Computer Application (PG) Syllabus Higher Secondary (XIXII)

This syllabus is designed to provide students with a comprehensive understanding of fundamental and advanced computer concepts, programming skills, and practical applications essential for higher secondary education and competitive examinations like WB SLST 2025.

1. Computer Basics

• Components of a Computer: Input/output devices, CPU, memory units, storage devices.
• Memory Types: Primary (RAM, ROM), Secondary (HDD, SSD), Cache, Virtual memory.
• Software Categories: System software, application software, utility programs.
• Programming Languages: Low-level, high-level, compiled, interpreted languages.

2. Computer Arithmetic

• Number Systems: Binary, decimal, octal, hexadecimal conversions.
• Complements: 1s complement and 2s complement representation and arithmetic.
• Character Codes: ASCII, BCD encoding and decoding techniques.

3. Digital Logic

• Boolean Algebra: Basic laws, simplification of expressions.
• Logic Gates: AND, OR, NOT, NAND, NOR, XOR, XNOR truth tables and applications.
• Combinational Circuits: Adders (half and full), subtractors.
• Sequential Circuits: Flip-flops (SR, JK, D), counters, registers.

4. Operating System

• Types of OS: Batch, multiprogramming, time-sharing, real-time.
• Process Scheduling: Concepts of process, threads, scheduling algorithms (FCFS, SJF, Round Robin).
• Memory Management: Paging, segmentation, virtual memory.
• Deadlock: Causes, prevention, avoidance, and handling techniques.

5. Data Structures

• Linear Data Structures: Arrays, stacks, queues operations and applications.
• Non-linear Data Structures: Trees (binary trees, binary search trees), graphs (basic concepts).
• Algorithms: Searching (linear, binary), sorting (bubble, selection, insertion).

6. Programming Languages

• C Language: Syntax, data types, control structures (loops, conditionals), arrays, pointers, functions, file handling.
• Object-Oriented Programming (C): Classes and objects, constructors and destructors, inheritance types, polymorphism (function overloading, overriding).

7. Database Management System (DBMS)

• Relational Model: Tables, keys (primary, foreign), relationships.
• SQL Queries: Data definition, data manipulation (SELECT, INSERT, UPDATE, DELETE).
• Normalization: Concepts and normal forms (1NF, 2NF, 3NF).
• Entity-Relationship Diagrams: Entities, attributes, relationships, cardinality.

8. Computer Networks

• Network Types: LAN, WAN, MAN, PAN.
• Network Topologies: Bus, star, ring, mesh, hybrid.
• OSI and TCP/IP Models: Layers and their functions.
• IP Addressing: IPv4 addressing, subnetting basics.
• Protocols: HTTP, FTP, SMTP purpose and usage.

Important Notes: Focus on practical applications and programming exercises. Understanding concepts through examples and hands-on practice is essential for exam success. Pay special attention to programming and DBMS query writing as these are frequently tested.
