Algorithms & Data Structures

Webpage for Algorithms

Webpage for Data structures

Book	Description
<br /> Introduction to Algorithms C.L.R.S	Cormen covers entire GATE syllabus (and much more) in Algorithms as well as Data Structures. Language is simple for most part but some mathematics is required to understand the analysis parts. (This book is only for learning algorithms and theory of data structures and there is no sample programs given in it)
<br /> Fundamentals of Computer Algorithms Rajasekaran, Sahni, Horowitz
<br /> Algorithm Design: Foundations, Analysis, and Internet Examples Michael T. Goodrich	This book is Mini version of Cormen’s book , this cover almost everything with short discussions, which is written in Cormen with more pages. Use this book along with NPTEL lecture of Professor Naveen Garg . Actually if you see prof Garg’s Nptel upon DS you will find slides are taken from this book. Slides are available online in the following link: http://ww3.algorithmdesign.net/handouts/
<br /> Design & Analysis of Computer Algorithms Aho, Hopcroft, Ullman	Another classic book for algorithms.
<br /> Algorithm Design Eva Tardos, Jon Kleinberg	Develops the intuition behind algorithms with excellent examples. Dynamic programming and Greedy algorithm are explained best. Many consider this to be better and more approachable than CLRS. This book and CLRS are the only two you’ll ever need, even without a tutor.

Databases

Webpage for Databases

Book	Description
<br /> Database Systems Elmasri, Navathe	Covers entire GATE syllabus and especially good for file structures and normalization
<br /> Database Systems Connolly, Begg	Covers entire GATE syllabus and is easy to understand.
<br /> Database Management Systems Raghu Ramakrishnan	Another very good book especially for Transaction management and Normalization.
<br /> Database System Widom, Ullman, Garcia-Molina	Another very good book.
<br /> Database System Concepts Silberschatz	Very good book but English is bit high standard

Compiler Design

Webpage for Compiler Design

Book	Description
<br /> Compilers : Principles, Techniques, & Tools Aho, Sethi, Ulman, Lam	One and only book. If you find the explanations tough, start looking at the given examples, they are easy to follow
“Compiler Design in C” Allen I Holub	A more practical and example oriented approach toward compilers. You’ll actually be able to construct a compiler after reading this. The perfect supplement to the “Dragon book”.

Operating Systems

Webpage for Operating systems

Book	Description
<br /> Operating System Concepts Silberschatz, Galvin	Very good for learning theory in OS. English is good to understand. Writing style is pretty easy and fun. Enough for GATE
<br /> Modern Operating Systems Tanenbaum	The Book , but if you read Galvin it is ok , read Tanenbaum for more Knowledge. It contains great number of problems. Also includes some of theory that is not included in Galvin’s book.
<br /> Operating Systems : Internals and Design Principles William Stallings	Strikes the perfect balance between theory and implementation. Galvin makes OS look too easy, which it isn’t. To the uninitiated, Tanenbaum may bog you down in implementation specific details, so much so that at times, you may loose sight of the forest a midst the trees. This book paired with Tanenbaum strikes the perfect balance.

Theory of Computation

Webpage for Theory of Computation

Book	Description
<br /> An Introduction To Formal Languages and Automata Peter Linz	Most recommended one for GATE
<br /> Introduction to Theory of Computation Sipser	Sipser is a quick and comprehensive guide. It is recommended to be read after you have grip on the subject.
<br /> Introduction to Automata Theory, Languages, and Computation Hopcroft	In most colleges you will find this book as a Main book, but believe me, if you read Linz, Enough!

CO & Architecture

Webpage for CO & Architecture

Book	Description
<br /> Computer Organization Vranesic, Zaky, Hamacher	Most recommended one and cache memory and pipelines are described well.
<br /> Computer Organization and Design Hennessy, Patterson	This is the preferred text in most top institutions of India. Even NPTEL IIT D lectures are based on it. That book is simply awesome, right from Basics to pipelining and advanced topics.
<br /> Computer Organization and Architecture : Designing for Performance Stallings	Another good book.
Computer Systems : An Integrated Approach to Architecture and Operating Systems Ramachandran	Among two of the best introductions to this subject, the other one being by Carl Hamacher.
Computer Systems: A Programmers perspective	This is a really good book in perspective of architecture as a simple view of how the actual hardware is organised is given. Apart from the classical confusing diagrams, this book has simple ones which is quite clear in its meaning. The explanation for pipeline execution and hazards are really good. This book is no longer in print, but you can get its pdf by clicking in the link provided. Highly recommended if you have time as this covers many of the other CS subjects as well.

Computer Networks

Webpage for Computer Networks

Book	Description
Computer Networks Peterson, Davie	Most recommended for GATE
<br /> Data Communication & Networks Forouzan	Good book with Basics clear
<br /> Computer Netwroks Tanenbaum, Wetherall	One can not neglect the amazing book by Tanenbaum. It contains everything in a very well written way. It is amusing and it deals with issues in a manner you want to do. If you are starting the subject, go with it. It is not recommended for last time reading. Keep making good notes if you read his book.
<br /> Computer Networking: A Top-Down Approach Kurose	Kurose is best for Almost all fundamental concept with clear figure and very understandable manners

Programming & Data Structures

Webpage for Programming & Data Structures

Book	Description
<br /> The C Programming Language Kernighan, Ritchie	No comments- This is the best. To really understand the working of C, you must read this book. If you find this book tough, that means you have to correct your concepts by talking to knowledgeable people. Many local books, skips difficult to digest concepts and make easy to read books- but to get everything you have to follow this book.
<br /> Data Structures Using C Aaron M. Tenenbaum	Recommended for data structure concepts. Most of the data structure concepts are covered in Cormen, but for those finding data structure problems difficult to do can use this book
Parameter Passing University of Washington	This pdf describes parameter passing mechanisms in detail
<br /> Data Structures and Algorithms in Java Roberto Tamassia Michael T. Goodrich	For those knowing Java, this book would be good to understand Data Structures
<br /> C Programming King	Can’t praise this one highly enough. Wins hands down over K&R as both introductory and intermediate resource for learning C. Especially attractive are the “Q & A” sections, which highlight points that don’t get a place in the conventional C literature. Even compares and contrasts the C99 standard with the classic “K&R” style C, wherever differences may arise. Has entire chapters dedicated to topics that don’t even get mentioned in other books. Just take a look at one of the copies floating around online and you’ll get the idea.
<br /> Pointers on C Kenneth Reek	Another gem of a book. Contrary to its name, this book is not only about pointers, though pointers get their significant share.
<br /> Understanding and Using C Pointers Richard Reese	If you got to have a book on pointers and memory management in C, this should be it, not the one by Kanetkar.

Digital Logic

Webpage for Digital logic

Book	Description
<br /> Digital Logic & Computer Design Morris Mano	No Comment… One and only…

Engineering Mathematics

Combinatory & Probability

Webpage for Combinatory

Webpage for Probability

Book	Description
<br /> A First Course in Probability Ross	Sheldon Ross’s book (1st course in Probability) is undoubtedly very good. But you have to read this book very deeply page by page.

Discrete Mathematics

Webpage for Mathematical logic

Webpage for Set Theory & Algebra

Book	Description
<br /> Discrete Mathematics and Its Applications with Combinatorics and Graph Theory Rosen	Best book for Discrete Mathematics. Even covers Graph Theory and Mathematical logic portions for GATE.

Graph Theory

Webpage for Graph theory

Book	Description
<br /> Introduction to Graph Theory Douglas B. West	First 4 chapters are important for GATE
<br /> Graph Theory With Applications To Engineering And Computer Science Deo	Good and concise books. If you have followed this book during bachelors, then it is enough for GATE.

Linear Algebra

Webpage for Linear Algebra

Book	Description
<br /> Higher Engineering Mathematics Grewal	Grewal’s book is sufficient for Linear Algebra in GATE (it is needed for other mathematical subjects)
<br /> Linear Algebra and its Applications Gilbert Strang	This is the best book for Linear algebra

Calculus

Webpage for Calculus

Book	Description
<br /> Higher Engineering Mathematics Grewal	Enough for GATE
Calculus Gilbert Strang	Recommended for those who love Mathematics.

General Aptitude

This is for 15 marks and syllabus is not strictly told as core CS. So, I advise to solve 5 questions daily for 3-4 months. You can follow here for questions.

Numerical Ability

Webpage for Numerical Ability

Book	Description
<br /> Quantitative Aptitude For Competitive Examinations Aggarwal	Those having good aptitude skills can do without this book. But do refresh the problems in progression, cost-selling price etc. Questions in aptitude are easy but scoring in this topic is very important to the final GATE score.

Verbal Ability

Webpage for Verbal Ability

Book	Description
<br /> A Modern Approach to Verbal Reasoning Aggarwal	If your English is good enough no need to buy this book. But I recommend giving a little importance to this topic.

To buy GO hardcopy 2020.

For GATE2020 softcopy will be made available subjectwise and as per GO classroom schedule. This will include 2 versions for each subject with first for previous year GATE+TIFR questions and second for other standard questions.

Softcopy of GO 2019 (last year version)

Volume 1: Engineering Mathematics, Discrete Mathematics, General Aptitude

Volume 2: Algorithms, Programming & DS, Compilers, Theory of Computation

Volume 3: CO & Architecture, Databases, Operating Systems, Computer Networks

Change Logs

Update July 2018

This is a major update with regard to formatting. Content wise GATE 2018 and a few other new questions were added. Most of the images were redrawn and most of the contents were formatted using Latex. Also, a different version was made for printing with BW theme and QR codes for all reference links.

Update September 2017

This is a minor update over the last one removing some non-previous year questions which happened to come by mistake and also removing the background for questions and answers for better print quality.

Update July 2017

GO PDF is now being made available in multiple volumes due to the large size of the PDF and for ease of printing. The first one containing Engineering Mathematics, Discrete Mathematics, and General Aptitude can be downloaded from below link. GO classroom account is same as GO account with a new password which is automatically emailed to all GO users. You can enroll on GATE 2018 course (all courses are free) and get a notice for further PDFs or any other updates.

Update on GO PDF hard copy shall be given by August second week.

http://classroom.gateoverflow.in/course/view.php?id=4

New Features:

GATE 1987-1990 and 2017 questions added
New color scheme
ISI/CMI questions also added
Questions in each topic are now counted
All the questions are classified to a topic

Update October 2016

This is the recommended book by me for Q/A for GATE. Last year, exams like ISRO, IIIT-H and some PSU exams including Kerala had many previous year GATE questions ditto. Though such things happen only for aptitude section in GATE, many other questions are derivatives of previous year questions. TIFR questions are also of the same level if not a bit harder. I do not recommend any other questions.

New features:

Added number of questions to each Category
Better Topic listing
Ability to move to topic heading from any question and category head from any topic
Moved all answers to end of each topic
Topics added as bookmark in supported PDF viewers
