Text compression techniques
A file reduced in size through the application of a compression algorithm, commonly performed to save disk space.
The act of compressing a file makes it unreadable to most programs until the file is uncompressed..
Text compression techniques
Increasing the compression ratio means increasing the distortion of the reconstructed signal, which implies a decrease in the transmission energy as well as the allocated bandwidth..
What is compression used for in computing?
Data compression is a reduction in the number of bits needed to represent data.
Compressing data can save storage capacity, speed up file transfer and decrease costs for storage hardware and network bandwidth..
What is data compression in computer networking?
Introduction.
Data compression reduces the size of data frames to be transmitted over a network link.
Reducing the size of a frame reduces the time required to transmit the frame across the network..
What is the compression ratio in networking?
Definition.
Data compression ratio is defined as the ratio between the uncompressed size and compressed size: Thus, a representation that compresses a file's storage size from 10 MB to 2 MB has a compression ratio of 10/2 = 5, often notated as an explicit ratio, 5:1 (read "five" to "one"), or as an implicit ratio, 5/1..
What is the concept of network compression?
Compression of data is often necessary when transmitting across a network for several reasons: Reducing bandwidth requirements: Compressing data can reduce the amount of data that needs to be transmitted, which can help to reduce the amount of bandwidth required to transmit the data..
- Lossless compression is necessary for text, where every character is important, while lossy compression may be acceptable for images or voice (the limitation of the frequency spectrum in telephony being an example of lossy compression).
