All the data and information are stored in a computer, as well as preloaded programs, are stored in the form of byte, each byte is stored on computer memory and this specific location is called address.
A different computer has a different
size of memory. Every manufacturer states computer memory size in terms of bytes.
Different Size of Memory
KB,MB,GB,TB
1 kilobyte (KB) is 1,024 bytes

1 megabyte (MB) is 1,024
kilobytes

1 gigabyte (GB) is 1,024
megabytes
|
1 terabyte (TB) is 1,024
gigabytes

Kb, Mb,Gb,Tb
1 kilobit (kb) is 1,024 bits

1 megabit (Mb) is 1,024 kilobits
|
1 gigabit (Gb) is 1,024 megabits

1 terabit (Tb) is 1,024 gigabits

Computers store all information in
the form of "1" and "0"s in different types of storages
such as memory, hard disk, USB drives, etc.
A bit is the smallest unit of data in a computer. A bit has a single binary value, either 0 or 1. The bit term was first used in 1946 by John Tukey, a leading statistician and adviser to five presidents.
A single bit can hold only one of two value: 0 or 1

When we use two-bit together then
we called crumb or we can say crumb is defined as 2 bits.
Four bits (Half a byte ) is called
a nibble. The nibble is used to describe the amount of memory used to
store a digit of a number stored in packed decimal format (BCD)
within an IBM mainframe. This technique is used to make computations faster and
debugging easier.
An 8-bit byte is split
in half and each nibble is used to store one decimal digit. The last
(rightmost) nibble of the variable is reserved for the sign.
A byte represents with the eight
bits, and is the most commonly used term to related for information stored
within a computer’s memory, The byte was first named in 1956, during the design
of the IBM Stretch computer.
There are eight bits in one byte
of information. bits are used to measure rates of data transfer. The
abbreviation “Mbps” is one of the most commonly misinterpreted in all of the modern computing it refers to megabits per second.
A byte is a number of
bits used to encode a character of text in the computer, which
depended on computer hardware architecture.
Bytes or multiples of these are
used to specify the sizes of computer files and the capacity of storage units.
Computers are designed to manipulate data in whole bytes or groups of bytes,
rather than individual bits.
The units of information are
defined as follows.

Examples of data storage:
1 bit – answer to a yes/no
question.
1 byte – a number from 0 to 255.
90 bytes: enough to store a typical line of text.
512 bytes = ½ KiB: the
typical sector of a hard disk.
1024 bytes = 1 KiB: the
classical block size in UNIX filesystems
1 GB – 114 minutes of uncompressed
CD-quality audio at 1.4 Mbit
Graphics also described by
the number of bits used to represent each dot. A 1-bit image
is monochrome an 8-bit image supports 256 colors or grayscales
