Data Representation in the Computer | Introduction to Data Representation

For the computer to be able to manipulate any data or information from whatever source, or act on any instruction, that data, information or instructions must be represented in a certain form that the computer can be able to process. In addition, any data or instructions entered into the computer must first be converted from human readable form to machine readable form for processing to take place. So, the way data or instructions are handled, stored, read, and even processed depends on the form in which they are represented. This is because data and instructions cannot be entered and processed directly into computers using human language. Therefore, this topic on data representation is very important because it helps computer users and professionals be able to gain some basic understanding on how the computer handles data under various systems. This topic on Data Representation in the Computer is thus covered in three parts, with this presentation being part 1 of 3 under the following headings: Concepts and reasons for data representation, Definition of terms, Number systems and their representation of integral values : Decimal, Binary, Octal, Hexadecimal, and Symbolic representation: BCD, EBCDIC, ASCII. You can also access part 2 of 3 and part 3 of 3 videos as posted in ‪@emeliswapict‬ YouTube channel. #computerstudies
