Coding theory is the study of the properties of codes and their fitness for a specific application. Codes are used for data compression, cryptography, error-correction and more recently also for network coding. Codes are studied by various scientific disciplines—such as information theory, electrical engineering, mathematics, linguistics, and computer science—for the purpose of designing efficient and reliable data transmission methods. This typically involves the removal of redundancy and the correction (or detection) of errors in the transmitted data.
There are four types of coding:
Data compression and error correction may be studied in combination.
Source encoding attempts to compress the data from a source in order to transmit it more efficiently. This practice is found every day on the Internet where the common Zip data compression is used to reduce the network load and make files smaller.
Well, the sun sets in the west
But as fast as you go
How would you know?
You're a busy boy, I guess
Who just wants the gold
At the end of the road
Think of all you miss
Passing through like this
You want an answer
As soon as you say a prayer
You want to land
The moment you're in the air
Baby, the living is all
In the getting there
Don't be the first in every line
Now and then you can be at the end
'Cause there's only so much time
And you can't get back
Every minute you spend
You're not even sure
What you're running for
You want an answer
As soon as you say a prayer
You want to land
The moment you're in the air
Baby, the living is all
In the getting there
Think of all you miss
Passing through like this
You want an answer
As soon as you say a prayer
You want to land
The moment you're in the air
Baby, the living is all
In the getting there
The living is all
In the getting there
