ICSE (Class X)
Syllabus (2013)
Subject: Computer Science
Class: X
There will be one paper of two hours duration carrying 80 Marks and Internal Assessment of 20 marks.
The paper will be divided into two Sections A and B.
Section A (20 marks): This section will consist of compulsory short answer questions, testing knowledge, application and skills relating to elementary/fundamental aspects of the entire syllabus.
Section B (60 marks): This section will consist of questions based on programming. There will be a choice of questions and candidates will be required to answer four questions from this section.
PART I -THEORY
1. Computer Structure
- Logic gates (NOT, AND, OR, XOR) and their use in computers.
- Review of number systems (binary, decimal, octal, hexadecimal), representation for different types - integers, float, characters.
- Simple binary arithmetic, including addition, subtraction, multiplication and division.
- Computer logic, Boolean operations, logical operators (NOT, AND, OR, XOR) and their truth tables.
The following points should be discussed:
- Some interesting real life examples can be taken to introduce propositional logic and fundamental Boolean operations.
- These can be connected to problem solving and programming.
- Verification of fundamental laws of Boolean algebra using truth tables.
- Writing inputs and outputs for a circuit like half adder and writing the SOP expression.
