It will be asumed that you are refering to the binary number system, which is used in computers and digital devices. A binary number is always either 0 or 1. This is also commonly refered to as "low" or "high". This is in contrast to the decimal number system, where the numbers can vary between 0,1,2,3,4,5,6,7,8 or 9.
hexadecimal
Number systems used mainly in encoding, cryptography, digital computing.
One of the biggest applications of digital logic is using circuits to perform arithmetical operations. While theoretically, any number system could be used, binary is the most simple to express in terms of digital logic circuits.
In it's simplest terms, a computer is actually a digital binary system. It is a very large number of containers or "bits" which are either numbered one ( for on) or zero (for off). As an electrical charge stores these alternating bit values, it is a digital system.
0xffef + 1 = 0xfff0.
Digital electronics deals with binary number system and the digital system can easily understand binary number system so processing is easy . no any more level like analog so chances of error reduce, very high speed of operation. These devices also require low power for proper operation.
A digital system can recognize digital data i.e. data only in form of 0 & 1, if data is not in digital form we have to convert it using analog to digital converters.
yes
