Memory units are used to measure and represent data. The data is stored in binary form (0 , 1).
Some of the commonly used memory units are:
BIT:-
It is the most basic information unit used in computing and formation theory. The smallest unit of data in a computer is called Bit (Binary Digit).
A single bit is 1 or 0, a true or false or a ‘flag’ which is on or off (use to distinguish two mutually exclusive states from each other).
A bit is abbreviated with a small “b”.
Nibble:-
Half a byte (four bits) is called a nibble.
BYTE:-
A byte is a collection of 8 bits. Eight-bit or bytes also known as Octets, the octets is a unit of digital information in computing and telecommunication that consist of 8 bits. The term is often used when the term 8 bytes might be ambiguous, as the byte has historically been used for storage units of a variety of sizes.
In most computer systems, a byte is a unit of data that is eight binary digits long. A byte is the unit most computers use to represent a character such as a letter, number or typographic symbol (for example, “g”, “5”, or “?”).
A byte is abbreviated with a capital “B”. A bit is abbreviated with a small “b”). Computer storage is usually measured in byte multiples.
Kilobyte:-
A kilobyte is unit information or computer storage equal to 1024 bytes. It is commonly abbreviated as KB.
In practical information technology, KB is actually equal to 210 bytes, which makes it equal to 1024 bytes. Decades ago, this unit used to be one of the most popular ones, but recently, since the volumes of information increased drastically, such unit as gigabyte has become more commonly used.
1KB= 1024 bytes
5KB= ? bytes
5×1024= 5120 bytes
Megabyte:-
A megabyte is unit of information or computer storage equal to 1024 kilobytes. It is commonly abbreviated as MB.
1 MB = 1024 KB
5 MB = ? KB
5×1024= 5120 KB
5MB = ? bytes
5×1024×1024= 6,164,480 bytes
Gigabyte:-
A gigabyte is unit of information or computer storage equal to 1024 megabytes. It is commonly abbreviated as GB.
Terabyte:-
A terabyte is unit of information or computer storage equal to 1024 gigabytes. It is commonly abbreviated as TB.
Petabyte:-
A Petabyte is unit of information or computer storage equal to 1024 Terabytes. It is commonly abbreviated as PB.
Exabyte:-
An Exabyte is unit of information or computer storage equal to 1024 Petabytes. It is commonly abbreviated as EB.
Zettabyte:-
A Zettabyte is unit of information or computer storage equal to 1024 Exabytes. It is commonly abbreviated as ZB.
Yottabyte:-
A Yottabyte is unit of information or computer storage equal to 1024 Zettabytes. It is commonly abbreviated as YB. At this time, no computer has one Zettabyte memory.
