BIT AND BYTE DIFFERENCE | SIZE COMPARISON

INTRODUCTION

BIT AND BYTE DIFFERENCE | SIZE COMPARISON – A binary digit is a simple form of the English word ‘bit’. Bit means zero or one! Every component in a computer’s memory is called a cell.

The smallest section of this cell is the bit! The number one or zero is stored in it. Computer programs and data are stored on the computer in the form of bitumen.

Many sets of bits are used to represent instructions or data in a program. This set is called ‘Word’. A word can have 16, 32, 48, or 64 bits.

In practice, however, the byte is a bit more of a string than a bit.

One byte is a set of 8 bits! The length of a computer’s word can also be expressed in bytes. Word is created by combining one, two, or more bytes.

Computer memory is usually measured in kilobytes. In practice, the word kilo means 1000, but in the context of a computer, one kilo means 1024.

Where did this number come from? Such a question will naturally arise in front of anyone. Here is the answer in the definition of the computer!

1 kilobyte = 2^10 = 1024 bytes

The ZX Spectrum computer has 48 kilobytes of memory. This means that the memory of this computer is 48 x 1024 = 49152 bytes.

The average memory of an IBM computer is 640 kilobytes. That means that the computer has a huge memory of 640 x 1024 = 3 655360 bytes.

One byte is eight bits. Remember! Many times the memory of a computer is also measured in megabytes. Mega is the 6th power of ten which is ten lakh bytes!

Personal computer memory can also be in the range of 10 to 20 megabytes recently.
