GATE Computer Science Syllabus


Cracking the GATE CSE exam can be challenging but those who will prepare with hard work can clear it with a good score. Candidates may select one or two papers from the pre-approved combination on the GATE exams, and CSE, or Computer Science and Information Technology Engineering, is one of these.

This article is most important for those who want to crack the GATE exam. Here you can get a brief of the GATE CSE Syllabus. Also here details are available for the whole syllabus on where to focus and priority subjects, so preparation will be more strategic.


Section 1: 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, 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.
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 public key and private key cryptography, digital signatures and certificates, firewalls.

Students need to focus on subjects according to weightage. In GATE CSE, Programming and data structure, Algorithms, COA, DBMS, OS, and TOC are important subjects. These all subject weightage are higher than another. General Aptitude is also a great key to clear GATE CSE because its weightage is 15 marks. So, you have to prepare core engineering subjects and General aptitude parallel. This GATE CSE data may vary because it depends on the examiner.

  • A suggestion is that you should not skip any subject or topic while preparing for GATE CSE. Students have to start at least one year before the GATE exam.
Opportunities After GATE for CSE Students:
  • Eligible for M.Tech/ME in reputed colleges.
  • Can go for CSE Research with a good stipend.
  • Teaching jobs are open for M.E/M.Tech candidates after GATE exam.
  • IOCL, NFL, NLC, ONGC, and ECIL are recruits through GATE score.
  • After clearing GATE, Can go abroad for study purposes.


Engineering Mathematics, Digital Logic, Computer Organization, and Architecture, Programming and Data Structures, Algorithms, Theory of Computation, Compiler Design, Operating systems, Databases, and Computer Networks are the major subjects for GATE CSE.

Not in India, but also in the world, CSE is the most demanding field. There is a number of scopes after GATE CSE.

Data Scientist, Data Analyst, Data Engineer, BI developer, and also many other fields are good for CSE students.

Top companies are L&T, Google, Microsoft, TCS, and Infosys which are providing high packages.

Yes, both branches syllabus are same in GATE CSE.
