Bit, Byte, Nibble, Word and Binary Arithmetic : Digital Logic

Bit, Byte, Nibble, Word and Binary Arithmetic : Digital Logic, what is bit?, what is byte?, what is nibble?, what is word?, what is binary arithmetic?, Bit, Byte, Nibble, Word and Binary Arithmetic : Digital Logic


Bit means binary digit, the smallest unit of information on a machine.  A bit has a single binary value, either 0 or 1. Where 0 means off and 1 means on or simply you can say false and true or no and yes.

Computer or digital devices can only understand bits or instruction that are provided in the form of bit.


It is the unit of storage which have the holding capacity of single character. On almost computers, a byte is equal to 8 bit 

for example, 
1024 byte = 1 KB  
10240 byte = 10 MB 
102400 byte = 100 MB etc... 


Half a byte (four bits) is called nibble. It means it is the combination of four binary digits or half or an eight - bit byte. A nibble can be conveniently represented by one hexadecimal digit. 


Technically word is a single unit of measurement that is assumed to be a 16-bits in length value. However, can be any set value, common values included: 16, 18, 24, 32, 36, 40, 48, and 64.

Binary Arithmetic

Binary means representation two digits which are 1 and 0. These two digits are also known as "On" and "Off" also may represent as "True" and "False".

Binary arithmetic system has base 2 and the base 2 system is a positional notation with a radix of 2.

The binary number system is different number system than other number systems. The coefficients of the binary number system have two possible values 0 and 1. Each coefficients is multiplied by 2.

i.e if a binary number 111011.11 is to convert in decimal than you have to do like this...
