Singing Exercises

These exercises are written to familiarise the pupil with the notes so
as to avoid giving him two difficulties to overcome at once^the length
and pitch of notes; they should therefore be practised exclusively whilst
the first chapters of Rudiments are being studied.
When the pupil can pitch the notes easily he should be exercised in
beating the measures of two, three or four pulses, counting these beats
instead of naming or sol-faing the notes. For this exercise strict evenness
in the duration of the beats must be observed/1*
This first task accomplished with care will ensure great facility for
all that follows; it is, besides, for teachers or mothers of families who
commence young children in this essential part of the art to direct them
according to their youthful intelligence.

An Entire MBA in 1 Course by Chris Haroun

The contents of this book are all based on my work experience at several firms, including Goldman Sachs, the consulting industry at Accenture, a few companies I have started, the hedge fund industry where I worked at Citadel and most recently based on my experience at a prominent San Francisco based venture
capital firm. I also included helpful practical business concepts I learned while I did an MBA at Columbia University and a Bachelor of Commerce degree at McGill University. Think of this book as a “greatest hits” business summary from my MBA, undergraduate business degree, work experience in consulting, equities, hedge funds, venture capital and starting my own companies.

Chris is currently a venture capitalist at a prominent San Francisco Bay Area venture capital firm and has previous work experience at Goldman Sachs and several firms that he has founded. He has successfully raised and also has managed over $1bn in his business/finance career. He has an MBA in Finance from Columbia University and a Bachelor of Commerce Degree with a

major in Management Information Systems and International Business from McGill University.

Common Mistakes in English With Exercises

This book has been designed to meet the requirements of students whose mother tongue is not English, Its main purpose is to help to correct the common mistakes to which foreign learners of English are liable.
The method adopted throughout this work is uniform. All the errors dealt with are singled out, for they have to be recognised before they can be corrected: then correct forms are substituted for incorrect ones; finally, simple
explanations are given wherever necessary to justify particular usages. Exercises are set al the end to ensure that the principles may become firmly fixed in the students' minds.
It is no! claimed that this manual is exhaustive. Nevertheless, the difficulties tackled are real, and the examples arc representative of the mistakes commonly
made by foreign students of English, being the result of observations made over a long period of time.
Much care has been given to the preparation of the Index, which it ?s hoped will make the book a useful work ol reference.

Using Quickbooks Accountant 2014 Glenn Owen

The first course in accounting has evolved significantly over the last several
years. Educators are responding to the demand of accounting and nonaccounting
faculty who rely on this course to lay a foundation for other courses. Moreover,
the accounting profession relies on this course to attract the ‘‘best and the
brightest’’ to become accounting majors. The evolution of this course has also
put pressure on instructors to integrate computers into the classroom and, in so
doing, develop students’ skills in intelligently using and interpreting accounting
Faculty often want to incorporate computerized accounting into the first
course but are reluctant to invest the time and effort necessary to accomplish
this laudable goal. Existing materials are often ‘‘preparer’’ driven in that they
focus on the creation of financial reports only. Students are often discouraged
in their use of computers in the first accounting course because of the confusing
and complicated accounting software manuals that concentrate on accounting
This text responds to all of these needs. It provides a self-paced, step-by-step
environment in which students use QuickBooks Pro 2014 or QuickBooks
Accountant 2014 to create financial statements and other financial reports, to
reinforce the concepts they learn in their first course, and to see how computer
software can be used to make business decisions.

Microsoft Computer Dictionary 5th Edition

The Microsoft Computer Dictionary, Fifth Edition is designed to be a comprehensive and authoritative source of definitions for computer-related terms and abbreviations. The dictionary includes terms drawn from a wide variety of topics relevant to computer users, including software, hardware, networking, data storage, graphics, games, information processing, the Internet and the World Wide Web, gaming, history, jargon and slang, organizations, programming, and standards.
Although this book covers nearly every aspect of computing, it does not include entries on most companies or on most makes and models of computers, nor does it contain entries on most application software products. The few exceptions to this rule of thumb are key companies and products that have a historical or universal importance within the computing industry.
This dictionary emphasizes terminology that the average computer user will encounter in documentation, online help, computer manuals, marketing and sales materials, the popular media, and the computer trade press. Because
most computer users operate personal computers and desktop systems at home, work, or both, the majority of the entries in this dictionary cover the terminology used in describing and working with these systems. However,
some specialized or highly technical language is included that pertains to areas of industry, academia, software and hardware development, and research. These terms have been included because they have a bearing on more common
computer terminology or because they are of historical significance.

Gul-Panra by Badshah room

a very interesting book in pashto language, read and enjoy. we are trying to upload as many books of pashto language as possible. but the real sorrow is this that there is a very small quantity of pashto readers.
a very interesting philosopy is lying in each line of this book.

“Sometimes, you read a book and it fills you with this weird evangelical zeal, and you become convinced that the shattered world will never be put back together unless and until all living humans read the book.” 
― John GreenThe Fault in Our Stars

Paradise on Fire Syed Ali Geelani and the Struggle for Freedom in Kashmir

When a man is denied the right to live the life he believes in, he has no choice but to become
an outlaw. —Nelson Mandela
PEACE IS A universal human yearning. Every society and every people need peace in order to flourish and to develop their resources, both individually and nationally. Nor is peace the mere absence of war. For peace of heart, mind and society can only exist when accompanied by the weighty presence of justice.
This book, then, is the story of one man’s self-sacrifice told through the struggle of an entire
people. Paradise on Fire is a call to the conscience of humanity. I pray that people from every part of the world will respond to this call and join the Kashmiri people in their non-violent resistance to oppression and occupation.
Free Kashmir, free Palestine!

Learn Python the hard way by Zed A. Shaw

Python is a widely used high-levelgeneral-purposeinterpreteddynamic programming language.

This simple book is meant to get you started in programming. The title says it’s the hard way to learn to write code, but it’s actually not. It’s only the “hard” way because it uses a technique called instruction. Instruction is where I tell you to do a sequence of controlled exercises designed to build a skill through repetition. This technique works very well with beginners who know nothing
and need to acquire basic skills before they can understand more complex topics. It’s used in everything from martial arts to music to even basic math and reading skills.

This book instructs you in Python by slowly building and establishing skills through techniques like practice and memorization, then applying them to increasingly diffi cult problems. By the end of the book, you will have the tools needed to begin learning more complex programming topics. I like to tell people that my book gives you your “programming black belt.” What this means is that
you know the basics well enough to now start learning programming.
If you work hard, take your time, and build these skills, you will learn to code.

Build Your Own Electric Car by S.Leitman and B.Brant

  Seth Leitman (Briarcliff Manor, NY) is currently President and Managing Member of the ETS Energy Store, LLC, which sells organic, natural, and
sustainable products for business and home use (from energy efficient bulbs to electric vehicle conversion referrals). Previously, he worked for the New York State Power Authority and the New York State Energy Research and Development Authority, where he helped develop, market, and manage electric and hybrid vehicle programs serving New York State and the New York metropolitan area. Seth is the consulting editor for a series of upcoming titles called the “Green Guru Guides,” which focus on implementing environmentally friendly technologies and making them work for you.
  Bob Brant was the author of the first book, and some might say ahead of his time in his passion to convert to electric. The first edition of this book was published in 1993. While there have obviously been updates and technological advances since that time, many of the concepts in that first book are still in use today. Bob grew up in New York City, got a BSEE, and worked on NASA projects such as Apollo, Lunar Excursion Module, and the Earth Resources
Technology Satellite. He then went on to get an MSEE and MBA, and worked for a company that worked on the Lunar Rover. Bob was always fascinated with every electric vehicle breakthrough, was convinced of its personal and environmental benefits, and was curious why stronger steps had not been taken to make electric vehicles a reality.
  Seth Leitman and everyone at McGraw-Hill would like to think of this updated edition as a tribute to Bob and other forward thinkers like him.

The electric vehicle’s time has come. The electric vehicle (EV) movement has broadened to multiple levels of the public debate. Al Gore and Leonardo DiCaprio have recently made movies about the need to assist the environment and how oil and energy have created the global warming problems that our world currently faces. Al Gore just won a Nobel Peace Prize for his discussion and call to action about global warming/climate change. The price of oil has recently fluctuated around $140 per barrel and $4.50 per gallon. Well, EVs solve a lot of problems quickly. Electric vehicles bypass high energy prices. Electric cars cost pennies to charge. Electric cars have zero tailpipe emissions.
While they charge up on electricity from power plants, they can also charge on electricity from solar, wind, and any other renewable resource. Also, if you compare emissions from power plants for every car on the road versus gasoline emissions, electric cars are always always cleaner. In addition, as power plants get cleaner and our power plants reduce emissions, electric cars will only get cleaner.
Electric cars also help develop the economy. We all know that we need to increase the number of electric cars. Hybrid electrics, plug-in hybrids, and low-speed vehicles all expand electric transportation. We as a country—no, we as world—are increasing our involvement in this industry. From China to India, to Great Britain to France, and back here in the United States, electric transportation can only create a new industry that will increase our manufacturing sector’s ability to build clean efficient cars. I recently spoke with an owner of an electric car company who said that the UAW was
more than excited to build electric cars since the traditional car companies were leaving Detroit in single file. This can only increase domestic jobs in the United States and help our economy. Our world is depending on fossil fuels from countries that predominantly have not supported the best financial interests of the United States. It is a national security issue for all of us to be sending over billions of dollars to countries that are politically unstable and/or antagonistic with Western nations. Another way to ask the questions is: Should we be sending more money to Iran and Venezuela, or should we
keep it in our own pockets? That is why I believe in a pollution-free, oil-free form of transportation. My first company’s tag line use to be “Pollution-Free, Oil-Free, It’s Good
To Be Free.” That is the mantra I would like to provide for this book! When you drive an electric vehicle, that is how you feel—free.

The Pathan(English) By Khan Abdul Ghani Khan

This is the English version of Ghani Khan's book 'The Pathan'

The folk-songs of a nation are its spiritual self-portraits, provided the race is primitive enough to be honest. It is easy to be honest in feeling __ one cannot help it __ but extremely difficult to be so in the expression of it, specially as men become civilized. When custom begins to dictate to instinct, when the eyes look more at the listeners than the face of the beloved, that is time when convention overcomes music, ethics overcome passion, and desire is substituted for love. So if you find the Pathan folk-songs too brutal and naked direct, do not forget that he lives a straight and primitive life in a lonely valley or small village, and is too busy worrying about the next thing to shoot, to find time to be civilized.
Let us go to his valley in Dir. There he is__ walking towards us, of medium height and sensitive build. He has long locks, neatly oiled and combed, wrapped in a red silk kerchief which is twisted round the head like the crown of Caesar. He wears a flower in his hair and collyrium in his eye. His lips are dyed red with walnut bark. He carries his sitar in his hand and his rifle at his shoulder. You would think he is very effeminate until you looked at his eyes. They are clear, manly and bold. They do not know fear, and won’t live long enough to know death. He pays the most lavish price for the made-up eyes and painted lips. This son of the bravest tribe of the Pathans never takes cover in

a fight and always laughs and sings when he is frightened. He will soon die fighting, a man as brave and strong and handsome as he, for he knows only how to love and laugh and fight and nothing else. He is taught nothing else. Let us listen to his song: 

O the flowers are lined
In your hair
And your eyes, O my beloved,
Are like the flowers of Narcissus.
O my priceless rare treasure,
O my life, O my soul,
O my little mountain poppy,
You are my morning star,
You the flower on the slope,
You the white snow on the peak.
Your laughter is the waterfall,
Your whispers the evening breeze.
O my branch of apple-blossom,
Who split moonlight in your eyes?
O my little butterfly,
Come and live in my heart.

The Pathan(Pashto) By Khan Abdul Ghani Khan.pdf

   This is the Pashto translation of Ghani Khan’s book The Pathan, read online or download for free.

Some Text from the book 
   The most difficult part of writing is to know where to begin, just as the most difficult part of speaking is to know where to stop. Nothing is more irritating than a blank sheet of paper staring stupidly into your face when you arc bursting to write but cannot make up your mind how to set about it.
   I want to talk about the Pathans, the people I love, which makes my task harder than ever. I want you to love them as I do. But the Pathan is not easy to love. He takes a lot of knowing. His is a most complicated simplicity. I want to bring him down from the peaks of Khyber and the fields of Hashnager face to face with you-in his torn clothes and grass shoes, his eyes full of manliness, laughter and the devil, and his head full of a childish and noble pride-the chief camouflage he uses to hide his poverty and want. Yes, I want to bring him to you and make him talk to you-of his struggle and his dreams, of love and feuds, his field and his watchtower, his new rifle and his old wife.
   The undertaking, you will admit, is difficult. No wonder I did not know where to begin. But I have a scheme. I shall make him sing his Jove-songs to you, so that you may feel the throb of his heart. He will tell you a Pathan fairy tale so that you may listen to what he tells his child. He will tell you a story of an incident in his village so that you may see how he lives. He will talk to you about the moon so that you may know how he loves. He will talk: to you about his customs so that you may understand his laws. He will talk of dacoities, raids and duels so that you may know the power that drives him. He will talk to you of priests and magic and charms so that you may know the darkness in his heart. He will talk to you of life and death and right and wrong, and I hope by that time you  know him and after you get to know him I shall butt in and try to talk about him, of his relation to you and his connection with your future. For whether you like it or not he is your neighbour. And on the most unfortunate side of your house- the side that faces Russia. You must know him because Russia will have a lot to say about the shape of things to come. They will come to the Pathan before they come to you.
   May I then introduce you to your neighbour! He has a fine turban and intriguing trousers. Let's have a look at him. But before we do that we might as well know something of his race and his origin.

From BCCI to ISI by Abid Ullah Jan

ENTRAPMENT is the illegal and unsavory practice of luring someone into committing a crime, and then prosecuting him for it. Sometimes the entrapped person, organization, or state has no intention or knowledge of the committed crime. The target becomes a victim of a set-up by government agencies, criminal elements, or a collaboration of both, all intent on achieving unstated objectives. Various agencies within the U.S. Government have been using entrapment in diverse ways.
“Frame-ups” in drug “conspiracies” are routine in the United States: there are literally thousands of drug-related conspiracy cases in the United States in which innocent people are implicated and punished. Arnold S. Trebach writes in his book, The Great Drug War: “In many of these cases, the DEA allowed some of its informants to traffic in drugs in exchange for turning in their friends and supplying other information. In too many cases, Gieringer claimed, DEA agents themselves
directly engaged in trafficking.”
Trapping innocent people is routine in the United States, and is by no means limited to crimes involving drugs. James Bovard gives numerous examples in his famous book: Lost Rights. Based upon his many years of research he concludes:
“During the past fifteen years, law enforcement officials have set up thousands of elaborate schemes to entrap people for ‘crimes’ such as buying plant supplies, asking for a job, or shooting a deer. Dozens of private accountants have become
double agents, receiving government kickbacks for betraying their clients to IRS.”
At the highest level, the classic example of entrapment, before Operation 9/11 to frame Osama bin Laden and company, was operation “C-Chase” in 1988, the purpose of which was to frame the Bank of Credit and Commerce International
(BCCI) and force its closure. Operation 9/11 is more complex because during this operation, Pakistan’s military intelligence agency (ISI) was entrapped while playing a role in facilitating 9/11.
Frame-ups are not a new idea for U.S. agencies. During the heyday of the Counter Intelligence Program (COINTELPRO), the FBI routinely used entrapment against members of the civil rights and antiwar movements. In a later, and much publicized, case known as Abscam, the FBI (at the behest of the Justice Department) used agents posing as Arab businessmen to bribe various public officials in return for political favors.
Writing in Governing magazine in 1998, Alan Ehrenhalt wrote, “Before the Abscam sting against members of Congress in 1980, the idea of inventing crimes and using them to tempt public officials was virtually unheard of in this country.”

If the FBI and U.S. Justice Department have no problem orchestrating witch hunts against public officials at home, what can we expect of them when it comes to safeguarding the country from the scourge of “international terrorism” from abroad? Especially when the neo-conservatives and religiously motivated officials of the current administration are determined to make invasion and occupation of Afghanistan and beyond their highest priority.

Active and Passive Voice Made Easy by Afzal Anwar Mufti

Need of English
The conditions under which English is taught in KPK (Khyber Pakhtunkhwa) is not conducive toteaching and learning the language. Courses are taught without specific curricular objectives;English language teachers are not equipped with efficient pedagogical tools; most Englishlanguage teachers rely on obsolete teaching techniques; inappropriate textbooks are chosen toteach English as a Second Language; language teaching facilities are not equipped with audiovisual aids; the examination system is erroneous, as it falls short of measuring attainment; andthe education system is lacking an observation and feedback mechanism.It is a fact that despite studying English in schools and colleges for about 6-8 years, students, especially coming from rural backgrounds, are not able to communicate inEnglish with relative ease and success. Even in some areas where students use a regionallanguage as a first language  besides Pashto - and in such areas English becomes a thirdlanguage  - they lack all the four major linguistic skills - reading, writing, listening, andspeaking. Since acquiring a second language is a skill, it should be approached in that light. It isclear that the methods of teaching the English language in Pakistan have not yielded the desiredobjective, i.e. communicative competence.

Problematic issues
1.       Shortcomings in the curriculum.
2.       Inefficient teachers.
3.       Methods and techniques.
4.       English language teachers incorporate.
5.       Inappropriate textbooks.
6.       Inadequate material facility.
7.       Erroneous examination system.

8.       lack of supervision

Dr. Abdul Qadeer Khan

Dr. Abdul Qadeer Khan is the undisputed hero of Pakistan's nuclear saga. Called "the father of the Islamic bomb," Dr. Khan pioneered and led Pakistan's effort to enrich uranium with gas centrifuges. In 1976 he took charge of the secretive Engineering Research Laboratories at Kahuta, now named the A.Q. Khan Research Laboratories in his honor, where he assembled the machinery and manpower it would take to produce weapon-grade uranium. Khan recruited scores of Pakistani scientists living abroad to work with him at Kahuta, boasting that "the scientists and engineers whom I recruited had never heard of a centrifuge, even though some of them were Ph.D.'s."

     Khan was born in 1936 in Bhopal, British India, into an Urdu-speaking family who were originally ethnic Pashtun.  His mother, Zulekha (née Begum), a housewife; his father, Abdul Ghafoor was an alumnus of Nagpur University and an academic who served in the British Indian Education ministry who permanently settled the family in Bhopal State after his retirement in 1935.  After the violent partition of India in 1947, his family emigrated from India to Pakistan in 1952, and settled in Karachi, Sindh. Briefly attending the D.J. Science College, he enrolled in Karachi University in 1956 to study physics.  In 1960, he graduated with degree in physics with minor in mathematics, where his degree concentration was in solid-state physics.

     For a short time, Khan worked for the city government as an inspector of weights and measures. In 1961, he went to Germany to study metallurgy at the Technical University in Berlin (TU Berlin) but made a transfer to Delft University of Technology in the Netherlands in 1965.  At Delft, he obtained engineer's degree in technology (an equivalent to MS) in 1967 and joined the Catholic University of Leuven for his doctoral studies. Supervised by Dr. Martin Brabers at Leuven University, Khan received D.Eng. in metallurgical engineering in 1972. His doctoral thesis dealt and contained fundamental work on martensite, and its extended industrial applications to the field of morphology— a field that studies the shape, size, texture and phase distribution of physical objects.

Understanding Islam

A Section From this Book

    When someone converts to Islam, God forgives all of his previous sins and evil deeds. A man called Amr came to the Prophet Muhammad(s.a.w) and said: “Give me your right hand so that I may give you my pledge of loyalty.” The Prophet (s.a.w) stretched out his right hand. Amr withdrew his hand. The
Prophet (s.a.w) said: { What has happened to you, O Amr? } He replied: “I intend to lay down a condition.” The Prophet (s.a.w) asked: { What condition do you intend to put forward? } Amr said: “That God forgive my sins.” The Prophet said: { Didn’t you know that converting to Islam erases all previous sins? }

    After converting to Islam, the person will be rewarded for his or her good and bad deeds according to the following saying of the Prophet Muhammad (s.a.w) : { Your Lord, Who is blessed and exalted, is most merciful. If someone intends to do a good deed but does not do it, a good deed will be recorded for him. And
if he does do it, (a reward of) ten to seven hundred or many more times (the reward of the good deed), will be recorded for him. And if someone intends to do a bad deed but does not do it, a good deed will be recorded for him. And if he does do it, a bad deed will be recorded against him or God will wipe it out. }

A prophet like Moses:

      There were hardly any two prophets who were so much alike as Moses and Muhammad (s.a.w) . Both were given a comprehensive law and code of life. Both encountered their enemies and were victorious in miraculous ways. Both were accepted as prophets and statesmen. Both migrated following conspiracies to assassinate them. Analogies between Moses and Jesus overlook not only the above similarities but other crucial ones as well. These include the natural birth, the family life, and the death of Moses and Muhammad (s.a.w)  but not that of Jesus. Moreover, Jesus was regarded by his followers as the Son of God and not exclusively as a prophet of God, as Moses and Muhammad (s.a.w)  were and as Muslims believe Jesus was. So, this prophecy refers to Muhammad (s.a.w)  and not to Jesus, because Muhammad (s.a.w)  is more like Moses than Jesus.
      Also, one notices from the Gospel of John that the Jews were waiting for the fulfillment of three distinct prophecies: 1) The coming of Christ, 2) The coming of Elijah, 3) The coming of the Prophet. This is obvious from the three questions that were posed to John the Baptist: “Now this was John’s testimony, when the
Jews of Jerusalem sent priests and Levites to ask him who he was. He did not fail to confess, but confessed freely, ‘I am not the Christ.’ They asked him, ‘Then who are you? Are you Elijah?’ He said, ‘I am not.’ ‘Are you the Prophet?’ He answered, ‘No.’” (John 1:19-21). If we look in a Bible with crossreferences,
we will find in the marginal notes where the words “the Prophet” occur in John 1:21, that these words refer to the prophecy of Deuteronomy 18:15 and 18:18.1 We conclude from this that Jesus Christ is not the prophet mentioned in Deuteronomy 18:18.

Computer Repair Service by Philip Spry - Lynn Spry

I love computers and have since I was in my early teens. Over the decades, I’ve watched them develop from giant clunky boxes with green screens to tiny works of art that project photo-realistic games on monitors the size of walls. I eagerly read each new issue of Byte and PC Magazine, waiting for the next breakthrough in hardware and software; it’s probably fair to classify me as a computer enthusiast. As a hobby, it’s relatively inexpensive.
     Think about it — the most expensive desktop CPU in existence at any given time is usually a little more than $1,000. That’s it! Imagine having the ability to buy a Formula 1 race car engine and pop it into your car for less than the cost of cable TV for a year! Of course, engines don’t double in power every two years, but the ease and simplicity of computer upgrades have made most of us relative experts in working on our own systems. Six years ago I was in this position. I had built my own computers for years and was the guy everyone came to for help. I’d been an IT professional for more than a decade so when my wife Lynn and I started looking for business opportunities we saw a computer store as a natural fit. I’d managed people for years and I loved computers. What could be better? I found a profitable store for sale, bought it, and prepared to enjoy my hobby while the money rolled in!

     What followed were the most grueling three years of my life. My wife and I received a crash course in retail sales, customer service, follow-up, technical support, marketing, and on-site service. The lessons in this book are the direct result of years of trial and error, and of failing miserably and working through it, to emerge successful, happy, and profitable.

Vladimir Holan - Selected poems

Vladimir Holan was born in Prague in 1905. He spent his childhood in the rolling wooded countryside of central Bohemia but returned to Prague for his secondary
schooling. In 1926 he published his first book of verse. For the next seven years he worked in a social insurance (pensions)officeand during this time published two further volumes of poetry. In 1929 he visited northern Italy; the fascination of its architecture, scenery and cultural past colours some of his later poetry. In 1933 he became editor of an arts review, Zivot (Life), but since 1940 has given
all his time to writing. He has published more than twenty volumes of poetry, apart from various selections and anthologies, and four prose works, including Lemuria (1940), his diary of the years 1934-8.

MCQs in Computer Science

This book is primarily written for undergraduate students of computer Science seeking admission to master’s program in computer science through examinations like GATE and GRE (in computer science). It will also be helpful for those taking computer science tests conducted by some companies for recruitment. It contains more than 1800 questions from the core areas of computer science. The questions are grouped subject wise.
The book now has sixteen chapters. The first chapter deals with the programming language C that is still popular  in spite of its age. The second chapter contains questions on UNIX, which has become popular due to its simple and easy to understand structure. In the third chapter, a veriety of problems based on the principles of programming languages are discussed.
The fourth chapter, Mathematical Foundations of computer science, has been revamped. It has questions based on the mathematical principles that are vital to the better understanding of computer science. Numerous problems from operations research, numerical methods, matrices and determinants, permutations and combinations, probability and statistics, discrete math, calculus and theory of equations are included in this chapter. In almost all the other chapters also some revision has been effected and additional questions included.

A new chapter on Oracle that covers SQL, PL/SQL, SQL *Plus, FORMS and REPORTS has been added towards the end of the book. Also included is the computer science question paper for GATE 2005 as an appendix. This will help the students in the preparation of their GATE examination.

Quantum Computing Explained by David McMohan

At the present time quantum computers are mostly theoretical constructs. However, it has been proved that in at least some cases quantum computation is much faster in principle than any done by classical computer. The most famous algorithm developed is Shor’s factoring algorithm, which shows that a quantum computer, if one could be constructed, could quickly crack the codes currently used to secure the world’s data. Quantum information processing systems can also do remarkable things not possible otherwise, such as teleporting the state of a particle from one place to another and providing unbreakable cryptography systems.
A classical computer has a memory made up of bits, where each bit is represented by either a one or a zero. A quantum computer maintains a sequence of qubits. A single qubit can represent a one, a zero, or any quantum superposition of those two qubit states; a pair of qubits can be in any quantum superposition of 4 states, and three qubits in any superposition of 8 states. In general, a quantum computer with  qubits can be in an arbitrary superposition of up to 2^ndifferent states simultaneously (this compares to a normal computer that can only be in one of these  states at any one time). A quantum computer operates by setting the qubits in a controlled initial state that represents the problem at hand and by manipulating those qubits with a fixed sequence of quantum logic gates. The sequence of gates to be applied is called a quantum algorithm. The calculation ends with a measurement, collapsing the system of qubits into one of the pure states, where each qubit is zero or one, decomposing into a classical state. The outcome can therefore be at most classical bits of information. Quantum algorithms are often non-deterministic, in that they provide the correct solution only with a certain known probability.

An example of an implementation of qubits of a quantum computer could start with the use of particles with two spin states: "down" and "up" (typically written   and , or  and ). But in fact any system possessing an observable quantity A, which is conserved under time evolution such that A has at least two discrete and sufficiently spaced consecutive eigenvalues, is a suitable candidate for implementing a qubit. This is true because any such system can be mapped onto an effective spin-1/2 system.
