**Computer Science and Information Technology** is one of the popular streams among engineering aspirants. It focuses on the basic elements of computer programming and networking. Before appearing in the exam, candidates must be well aware of the syllabus and GATE Exam Pattern. As per GATE latest pattern, **70% of Exam have Core Engineering Syllabus or subject syllabus, 15% of Engineering Mathematics, and 15% of General Aptitude**. Candidates can go through the syllabus given below to get an idea about GATE syllabus.

**SYLLABUS FOR GENERAL APTITUDE (GA) (COMMON TO ALL PAPERS) ****Verbal Ability****:** English grammar, sentence completion, verbal analogies, word groups, instructions, critical reasoning and verbal deduction.**Numerical Ability:** Numerical computation, numerical estimation, numerical reasoning and data interpretation.**COMPUTER SCIENCE AND INFORMATION TECHNOLOGY****Section 1: Engineering Mathematics****Discrete Mathematics:** Propositional and first order logic.

**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.**GATE LATEST EXAM PATTERN **

Students who would appeared in the exam understood the GATE exam pattern. The exam was held as a single paper of 3 hours duration consisting of questions from aptitude and the respective subject. The detailed latest exam pattern of GATE CS and IT is given below:
