Digital+and+Analog+Communication

=What is?=


 * Digital** communication is the change of information such as pictures, sounds and text into a computer readable format by changing them into a sets of 0's and 1's that have the ability to carry information that is encoded.


 * Analog** communication is the movement of information using continuously varying signals matching the sound and light originated by the source.

=The Benefits of Turning Digital:=

1. **Quality:** Digital signals are not influenced by interference and distortion as much as analog siglans and therefore the transmission quality will improve. Due to the use of the 1's and 0's as information carriers, the information can be restored clearly and any noise will be removed. On the other hand, the noise in the analog systems kept on adding to the noise everytime the information is reproduced.

2. **User Control:** Since there is a wide variaty of choices when it comes to choosing something spicific on a certain system. Digital systems such as digital radios give the user the chance to navigate though stations using search engines, where they input commands such as 'Trance seek' to find what they like in a shorter time span. Additionally filtering programs could be used in digital systems such as recievers to put away unwanted material such as sexual content.

3. **Channel Abundance:** Due to new methods in digital compression, useless repeated information can be eradicated and thus, allowing multiple channels to be available when only one was before. In other words, now it is possible to broadcast a variaty of programs simultaneously on digital cable television. Furthermore packet switching made it possible for users to share the same transmission channel simultaneously by taking turns, and the use of Fiber optic systems will only enhance such technology.
