Computer Science (PG) WB SLST 2025 Syllabus

This syllabus is designed for Class XI-XII students preparing for the WB SLST 2025 examination. It covers fundamental and advanced concepts in computer science, focusing on both theoretical understanding and practical applications.

1. Basics & Number Systems

• Computer Generations: Evolution from first to fifth generation computers, characteristics and examples.
• Computer Architecture: Basic components of a computer system including CPU, memory, and I/O devices.
• Number Systems: Understanding and conversion between binary, octal, decimal, and hexadecimal systems.
• Data Representation: Binary Coded Decimal (BCD), ASCII codes for characters, Gray codes and their applications.

2. Digital Logic

• Logic Gates: AND, OR, NOT, NAND, NOR, XOR, XNOR gates and their truth tables.
• Combinational Circuits: Design and working of adders (half and full), subtractors.
• Multiplexers and Demultiplexers: Concepts and practical uses.
• Sequential Circuits: Flip-flops (SR, JK, D, T), counters (synchronous and asynchronous).
• Boolean Algebra: Laws and theorems, simplification of Boolean expressions.

3. Computer Organization

• CPU Structure: Components like ALU, control unit, registers and buses.
• Instruction Formats: Types of instructions and their formats.
• Addressing Modes: Immediate, direct, indirect, register, and indexed addressing.
• Memory Hierarchy: Cache, primary and secondary memory, characteristics and usage.
• I/O Devices: Types, functions, and interfacing basics.
• Arithmetic Logic: Basic arithmetic operations and logic operations inside the CPU.

4. Programming Fundamentals

• Algorithms: Definition, characteristics, and designing simple algorithms.
• Flowcharts and Pseudocode: Representation techniques for problem-solving.
• Complexity Analysis: Basic understanding of time and space complexity.
• Structured Programming: Concepts of sequence, selection, and iteration.
• System Software: Overview of operating systems, compilers, and assemblers.
• Data Structures: Introduction to arrays, stacks, queues, and linked lists.

5. Programming Languages

• BASIC: Syntax, simple programming constructs, and applications.
• C Language: Data types, control structures, functions, arrays, pointers, and file handling.
• C Language: Object-Oriented Programming concepts including classes, objects, inheritance, polymorphism, and encapsulation.
• Data Structure Implementations: Using C/C to implement stacks, queues, linked lists, and trees.

6. Software & Packages

• Operating System Utilities: Basic DOS/Linux commands for file and directory management.
• Shell Scripting: Writing simple scripts for task automation.
• Office Packages: Usage of spreadsheets, word processors, and presentation software.
• StarOffice Suite: Overview and practical applications.

7. Computer Networks & Web

• Network Basics: Types of networks (LAN, WAN), topologies, and protocols.
• Client-Server Model: Architecture and communication process.
• Internet Tools: Email, chat, FTP, and WWW essentials.
• Web Technologies: Introduction to HTML, CSS basics, and simple scripting for web design.

Important Notes & Tips

• Focus on understanding concepts rather than memorization.
• Practice programming regularly to build problem-solving skills.
• Use flowcharts and pseudocode to plan your programs before coding.
• Revise Boolean algebra and digital logic with practical circuit examples.
• Explore hands-on experience with Linux commands and shell scripting.
• Develop simple web pages to strengthen your understanding of HTML and scripting.

This syllabus aims to prepare students thoroughly for the WB SLST examination by balancing theory with practical exercises and real-world applications.
