Before learning about the types of memory, we learn together about the units of
memory measurement.
Memory measurement units:

Information is stored and processed in the computer in the form of bits. A bit
is the smallest unit that carries or transmits information. Thus, the term bit
expresses numbers in the binary number system, and it is the basic unit of the
amount of information in computers and digital communications. This unit can
only have one of two values and is therefore physically implemented in a two-
state machine.

A bit is one bit of a binary number system and has only two possibilities (or
two positions). Either the bit is 0 or 1 .
1 byte equals 8 bits, 1,024 bytes equals 1 kilobyte.
Please refer to the table below for all memory measurement units.

bit 0 or 1
Byte equals 8 bit

Kilobyte Kb equals 1024 Byte
Megabyte Mb equals 1024 Kilobyte
Gigabye Gb equals 1024 Megabyte
Terabye TB equals 1024 Gigabye
Petabyte PB equals 1024 Terabye
Exabyte EB equals 1024 Petabyte
Zettabyte ZB equals 1024 Exabyte
YottaByte YB equals 1024 Zettabyte
