- Reducing the number of bits present in transmit data.
Methods of Data compression:
Lossless and Lossy methods:
Advantages:
- Storage space can be reduced.
- Reduces the bandwidth of the transmitted file.
- Increase the speed of transmitted file.
- Downloading speed is high.
- Less time consuming.
- Added complication.
- Effect of error in transmission.
- Need to decompress all previous data.
