How are data being represented in computers?
Computers work with a binary number system that consists of only two digits - zero and one. Inside the computer binary number is represented by an electrical pulse. One means a pulse of electricity and zero means no pulse. All the data entered into computers is first converted into the binary number system. One digit in binary number system is called bit and combination of eight bits is called byte. A byte is the basic unit that is used to represent the alphabetic, numeric and alpha numeric data

Data is the combination of characters, numbers and symbols collected for a specific purpose. Data is divided into three types; alphabetic data, numeric data and alphanumeric data. Numeric data consist of ten digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, two signs + and - and decimal point. There are different types of number system that are used to represent numeric data. These number systems are decimal number system, binary number system, octal number system and hexadecimal number system.

Alphabetic data is used to represent 26 alphabetic. It consists of capital letters from A to Z, small letters from A to Z and blank space. Alphabetic data is also called non numerical data. Alphanumeric data used to represent alphabetic data, numeric data, special character and symbols.
Data is represented inside a computer as a series of on and off pulses. Humans think of those pulses in terms of a binary-based numbering system.

Number Systems in Computer * Binary Number System - The binary number system is a numbering system that represents numeric values using two unique digits (0 and 1). Mosting computing devices use binary numbering to represent electronic circuit voltage state, (i.e., on/off switch), which considers 0 voltage input as off and 1 input as on.

This is also known as the base-2 number system, or the binary numbering system.

* Octal Number System - The octal numeral system, or oct for short, is the base-8
