A Survey on Different Text Data Compression Techniques

Apoorv Vikram Singh ^[2] | Garima Singh ^[7]

Abstract: Data Compression refers to the process of reducing the data size and removing the excessive information. The main objective of data compression is to reduce the amount of redundant information in the stored or communicated data. Data compression is quite useful as it helps us to reduce the resources usage such as data storage space or transmission capacity. It finds its application in the area of file storage and distributed system because in distributed system we need to send data from and to all the systems. Data compression techniques are mainly used for speed and performance efficiency along with maintaining the cost of transmission. There are number of different data compression methodologies, which are used to compress different data formats like text, video, audio, image files. Data compression techniques can be broadly classified into two major categories, lossy and lossless data compression techniques. In this paper, reviews of different basic lossless data compression methods are considered and a conclusion is drawn on the basis of these methods.
