Data compression techniques in Computer network
Data compression is the process of encoding, restructuring or otherwise modifying data in order to reduce its size.
Fundamentally, it involves re-encoding information using fewer bits than the original representation..
Data compression techniques in Computer network
Effect and typical ratios.
A high compression ratio is desirable because it allows an engine to extract more mechanical energy from a given mass of air–fuel mixture due to its higher thermal efficiency..
Data compression techniques in Computer network
It's a measure of how much the cylinder volume has been compressed. 10:1 the volume has been compressed down to 1/10 of original volume. 12:1 the volume has been compressed down to 1/12 of original volume..
How does compression ratio work?
The compression ratio is defined as the ratio between the volume of the cylinder with the piston in the bottom position, Vbottom (largest volume), and in the top position, Vtop (smallest volume).
The higher this ratio, the greater will be the power output from a given engine..

What is data compression and how does it work?

What is the compression ratio of data?
To determine the compression ratio, divide the size of outputFile value by groupPages value.
For example, if the size of outputFile value is 40 000 bytes and the size of the group of pages is 200 000 bytes, then the compression ratio is 40000/200000 or 0.20 (5:1 compression)..
