Memory Units of Computer

MEMORY UNITS OF COMPUTER

Hello Readers,
Here we are representing to you all about "Memory units of computer" which can be very important for you...

DATA REPRESENTATION - 
Memory Units:

Binary Number = 0,1 (Machine Language)

4 bit = 1 nibble
8 bit = 1 byte
1024 B = 1 KB (Kilo Byte)
1024 KB = 1 MB (Mega Byte)
1024 MB = 1 GB (Giga Byte)
1024 GB = 1 TB (Tera Byte)
1024 TB = 1 PB (Peta Byte)
1024 PB = 1 XB (Exa Byte)
1024 XB = 1 ZB (Zeta Byte)
1024 ZB = 1 YB (Yota Byte)

bit < Byte < KB < MB < GB < TB < PB < XB < ZB < YB

Data:
  • The information you put into the computer is called Data.
  • Information of a computer is stored as Digital Data.
  • There are two basic types of Data, which are stored and processed by the computer:     1.Character      2. Number
1 Character = 1 Byte
1 Number = 2 Bytes
-1 Number = 4 Bytes

Bits (b):
The term Bit is nothing but the contracted form f Binary Digit.
A bit is the smallest possible units of Data.

Bytes (B):
the byte is the basic unit for measuring the size of the memory.

Mbps – mega bits per sec.
MBps – mega Bytes per sec.
