Question

difference between bit and byte

Answer 1

Actually no, there's a big difference between a bit and a byte. A byte is much bigger: eight times bigger, in fact, with eight bits in every byte. By extension, there are eight megabits in every megabyte and 1 gigabyte is 8 times bigger than 1 gigabit.

Answer 2

Computer memory :

BITE :

A computer can only understand two things that is "OFF" and "ON" - OFF represents " 0 " and ON represents " 1 " .In computer we know the computer only understands "binary digits" that 0,1 .These two digits - 0s and 1s are called "Bits/binary digits".

BYTE :

The amount of instructions and data that is stored in a computer memory is measured as "Bytes".

There are two types of computer memory:

1. Internal Memory.
2. External Memory.

Memory Size Table :

8 bits = 1 Byte

1024 Bytes = 1 kilo Byte ( 1 KB )

1024 KB = 1 Mega Byte ( 1 MB )

1024 MB = 1 Giga Byte ( 1 GM )

1024 GM = 1 Tera Byte ( 1 TB )

1024 TB = 1 Peta Byte ( 1 PB)

1024 PB = 1 Exabyte ( 1 ZB )

1024 ZB = 1 Yottabyte ( 1 YB )

Types of computer memory :

(1) Memory :-

1. Internal Primary Memory.
2. External Secondary Memory.

(2) Internal Primary Memory :-

1. RAM (Random access memory).
2. ROM (Read only memory).

(3) External Secondary Memory :-

1. Hard Disk.
2. CD / DVD / Blu-ray Disk.
3. Flash Disk.
