# How to ready for GATE

GATE: Graduate Aptitude Test in Engineering(GATE) is all India basis examination which is conducted by all IITs joint initiative every year of February. If you want to get a Masters in Engineering/Technology in IITS then you have to score well to get a chance.GATE is an entrance examination for IIT M.Tech admissions.GATE scores are also considered as a compulsory criterion for many PSUs nowadays.

### What is the Exam pattern of GATE?

First of all the duration of this exam is 3 hours. There are two types of questions. One is MCQ(Multiple Choice Questions)and other is NAT(Numerical Answer Type Questions). The total number of questions are 65 questions with total 100 marks Gate question paper consists of three sections.
1)General Aptitude
2)Engineering Mathematics
3)Subject-specific sections

### What is your syllabus for Computer Science/Information Technology?

Many of you are thinking that why I am giving only the syllabus of Computer Science/Information Technology. There are so many streams are Engineering. And from all background students can prepare for GATE. But the point is that I am from a Computer Science background and I did the Exam two times. So I know very well the syllabus of Computer stream.

Syllabus: There are ten sections of the syllabus for Computer Science including Engineering Mathematics.
Section1: Engineering Mathematics
Discrete Mathematics: Propositional and first-order logic. Sets, relations, functions, partial
orders and lattices. Groups. Graphs: connectivity, matching, coloring. Combinatorics:
counting, recurrence relations, generating functions.
Linear Algebra: Matrices, determinants, the system of linear equations, eigenvalues and
eigenvectors, LU decomposition.
Calculus: Limits, continuity, and differentiability. Maxima and minima. Mean value
theorem. Integration.
Probability: Random variables. Uniform, normal, exponential, Poisson and binomial
distributions. Mean, median, mode and standard deviation. Conditional probability and
Bayes theorem.
Computer Science and Information Technology
Section 2: Digital Logic
Boolean algebra. Combinational and sequential circuits. Minimization. Number
representations and computer arithmetic (fixed and floating-point).
Section 3: Computer Organization and Architecture
Machine instructions and addressing modes. ALU, data‐path and control unit. Instruction
pipelining. Memory hierarchy: cache, main memory, and secondary storage; I/O
interface (interrupt and DMA mode).
Section 4: Programming and Data Structures
Programming in C. Recursion. Arrays, stacks, queues, linked lists, trees, binary search
trees, binary heaps, graphs.
Section 5: Algorithms
Searching, sorting, hashing. Asymptotic worst-case time and space complexity.
Algorithm design techniques: greedy, dynamic programming and divide‐and‐conquer.
Graph search, minimum spanning trees, shortest paths.
Section 6: Theory of Computation
Regular expressions and finite automata. Context-free grammars and push-down
automata. Regular and context-free languages, pumping lemma. Turing machines and
undecidability.
Section 7: Compiler Design
Lexical analysis, parsing, syntax-directed translation. Runtime environments. Intermediate
code generation.
Section 8: Operating System
Processes, threads, inter‐process communication, concurrency, and synchronization.
Deadlock. CPU scheduling. Memory management and virtual memory. File systems
Section 9: Databases
ER‐model. Relational model: relational algebra, tuple calculus, SQL. Integrity constraints,
normal forms. File organization, indexing (e.g., B and B+ trees). Transactions and
concurrency control.
Section 10: Computer Networks
Concept of layering. LAN technologies (Ethernet). Flow and error control techniques,
switching. IPv4/IPv6, routers and routing algorithms (distance vector, link state). TCP/UDP
and sockets, congestion control. Application layer protocols (DNS, SMTP, POP, FTP, HTTP).
Basics of Wi-Fi. Network security: authentication, basics of a public key and private key
cryptography, digital signatures, and certificates, firewalls.

### From which subject I should start my preparation?

At the initial stage, you should focus only on your preparation. So you should start from the easy subject so that you can easily remember the topics. This will help you to build confidence. But if you start a difficult subject it can ruin your confidence level and it will hamper your preparation strategy.

### What are the key points you should remember for GATE preparation?

1)Understand the GATE syllabus
2)Plan the GATE preparation
3)Gather important resources
4)Study good and relevant books
