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 contex-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).
