What are megabytes and megabits?

For those who are new to computers, i know you always encounter puzzled with this terminologies so what are megabytes and megabits..

Bit: short form for binary digit. It is either a 0 or a 1 (binary code).

1 byte= 8 bits.

1 kilobyte = 1024 bytes.

1 megabyte = 1024 kilobytes.

Computers are electronic devices so they view everything as either being ON or OFF. By stringing together groups of on and off messages, computers can store and process information.

The code for ON and OFF are represented numerically as either a one (1) or a zero (0). 1=ON, 0=OFF. Individually, each one or zero is called a Binary Digit or BIT for short.

A collection of 8 BITS (or eight zeros and ones) is equal to 1 BYTE

In human terms, 1 BYTE is equal to one character (a letter, number, space, dash, etc.)

For example, when you type the letter "A" your computer sees "01000001" and if you type the letter "a" in lowercase it sees "01100001." Each zero and one by itself is a BIT; each collection of eight BITS makes up one BYTE.

1 Bit = 1 Binary Digit (either a 0 or a 1)
8 Bits = 1 Byte (1 Byte = 1 CHARACTER)
1,024 Bytes = 1 Kilobyte (KB)
1,024 Kilobytes (KB) = 1 Megabyte (MB)
1,024 Megabytes (MB) = 1 Gigabyte (GB)
1,024 Gigabytes (GB) = 1 Terabyte (TB)
1,024 Terabytes (TB) = 1 Petabyte (PB)
1,024 Petabytes (PB) = 1 Exabyte (EB)

Generally - Bits are used to talk about data transfer rates (1 kilobit = 1000 bits), while bytes are used to talk about storage size calculations (1 kilobyte = 1024 bytes). So when your Internet provider offers you a 1Mb connection, its megaBits not MegaBytes. So for a rough guide of how MUCH you can download, divide by eight. i.e. 1Mb speed = 128KB of data.

8 bits = 1 byte. so yung megabytes and megabits are 2 different measurements.
