Unit for Data Measurement

There are 8 bits in 1 byte, and 16 bits in 2 bytes. A 16-bit value is called a word

Bits, Bytes, Mega, Giga, Tera

1 bit = a 1 or 0 (b)
4 bits = 1 nybble (?)
8 bits = 1 byte (B)
1024 bytes = 1 Kilobyte (KB)
1024 Kilobytes = 1 Megabyte (MB)
1024 Megabytes = 1 Gigabyte (GB)
1024 Gigabytes = 1 Terabyte (TB)

BIT :

- A bit is the smallest unit of data that the computer can process. Bit is a short for binary digit. A bit is represented by the numbers 1 and 0. These numbers represent the binary system. They correspond to the states of on and off, true and false, or yes and no.

- All digital data use the binary system to process the information. This information include letters, digits or special character.

BYTE :

- Byte is a unit of information built from bits. One byte is equals to 8 bits. Eight bits that are grouped together as a unit. A byte provides enough different combinations of 0s and 1s to represent 256 individual characters.

- One byte represents a single character such as the number 3, letter b or a $ symbol. Bits and bytes are the basis for representing all meaningful information and programs on computers.

CHARACTER

8 bits = 1 byte

- One byte represents one character such as A, 7, 9 and +.Eight bits that are grouped together as a unit. A byte provides enough different combinations of 0s and 1s to represent 256 individual characters.

KILOBYTE (KB)

- In mathematics, 1 KB = 1000 bytes.

- In computer, 1 KB = 1024 bytes or can be said as:

1 KB = 2¹⁰ bytes

-This is how we get the calculation for 1024 bytes.

MEGABYTE (MB)

- 1 MB = 1 048 576 bytes or it can be said as:

1 MB = 2²⁰ bytes

GIGABYTE (GB)

- 1 GB = 1 073 741 824 bytes or it can be said as:

1 GB = 2³⁰ bytes

TERABYTE (TB)

- 1 TB = 1 099 511 627 776 bytes or it can be said as:

1 TB = 2⁴⁰ bytes
