Digital Media

1)Digital Madia is all aroung us these days. Its everywhere you turn for example:

* Cellphones

* e-book

* Digital Vedio

* Internet

2)Today Digital media is based on the binary numeral system. The two numbers that a used to code all digital date are "0" and "1"

3) A bit is the basic unit of information in computing and tellecommunication, it is the amount of information that can be stored by a device or other physical system that can mormally exist in only two distinct states.

The byte is a system of digital information in computing and telecomunications. it is an ordered collection of bits.

4) The sampiling rate, sample rate, or sampling frequency difines the number of samples per second(or per other unit) taken from a continuous signal to make a descrete signal

5) 1bit (2 colours) 4 bit (16 colours) 24bits (every colour)

6) Still media doesnt have sound so does not require sampling rate. Where as video digital meadia requires sound therefore needs sampling rate
