a) To explain the concepts and reasons for data representation in a computer.

b) To define the terms bit, byte, nibble, and word.

c) To explain the different types of data representation in a computer.

d) To perform binary arithmetic operations.

6.2.0 Content

The content of this topic includes the following sub-topics:

6.2.1 Concepts and reasons of data representation

This sub-topic focuses on explaining the concepts and reasons behind data representation in a computer. It covers the importance of representing data in a way that a computer can understand and process.

6.2.2 Definition of terms bit, byte, nibble, and word

In this sub-topic, learners will learn the definitions of important terms related to data representation, such as bit (binary digit), byte (a group of 8 bits), nibble (a group of 4 bits), and word (the amount of data that can be processed by the computer’s CPU in one operation).

6.2.3 Types of data representation

This sub-topic covers different types of data representation. It includes the representation of integral values in decimal, binary, octal, and hexadecimal number systems. It also covers symbolic representation, such as Binary Coded Decimal (BCD), Extended Binary Coded Decimal Interchange Code (EBCDIC), American Standard Code for Information Interchange (ASCII), and the conversion between binary and decimal.

6.2.4 Binary arithmetic operations

In this sub-topic, learners will learn how to perform binary arithmetic operations. It covers binary addition and subtraction, including ones complement and twos complement.

By following this course outline, learners will gain a comprehensive understanding of data representation in a computer and be able to apply their knowledge in performing binary arithmetic operations.
