Units of Computer Memory

Units of Computer Memory is the part of Computer System. All the computer data which we are entered are stored in these Computer Memory. Here in this topic we will discuss the Units of Computer Memory and its sequence.


Units of Computer Memory and its Sequence

BIT

A binary digit is called a bit. It expressed as 0 and 1 the two numbers of the binary number system. A bit is the smallest units of computer information a computer can use. A 16 bit computer would process a series of 16 bits, such as 0100111101011000, repeating the process thousands or millions of times per second. Reading a series of bits is very difficult and to make this process easier they are often displayed in groups of 4 bits 0100 1111 0101 1000.
This grouping is quite interesting in that a group of 4 bits can be replaced by a single hexadecimal digit. Two groups of 4 bits, i.e. 8 bits ( a byte) can be replaced by 2 hexadecimal digits, and 4 hexadecimal digits are required to replace all 16 bits. There are some units of Computer.

Units of Computer Memory


BYTE

A group of 8 bits are called a byte. If 1 byte can store one alphabetical letter, single digit,or a single character/symbol, such as #.Then Large numbers of bytes can be expressed by kilobyte and megabyte.

KILOBYTE

The value of a kilobyte is 1024. Worked out as 2^10. Normally Kilo refers to 1000 but in computing kilobyte is 1024. It is represented as KB.

MEGABYTE

1024Kb is referred to as a "Megabyte". Mega refers to a million. In computing 1 Mega byte is 1,048,576 bytes. Worked out as 2^20, or 1024*1024. It is represented as MB.
1 byte of memory can normally hold one of the following:
a single alphabetical letter (upper or lower case),
a single number 0-9,

a symbol ( _ + £ # > etc
