data compression
1. Increasing the amount of data that can be stored in a given domain, such as space, time, or frequency, or contained in a given message length. 2. Reducing the amount of storage space required to store a given amount of data, or reducing the length of message required to transfer a given amount of information. Note 1: Data compression may be accomplished by simply squeezing a given amount of data into a smaller space, for example, by increasing packing density or by transferring data on punched cards onto magnetic tape. Note 2: Data compression does not reduce the amount of data used to represent a given amount of information, whereas data compaction does. Both data compression and data compaction result in the use of fewer data elements for a given amount of information.

Data Compression
A method of reducing the number of bits that are needed to represent information. Data compression allows gigher communications speeds and allows more information to be stored on a disk.

Data compression
In computer science and information theory, data compression or source coding is the process of encoding information using fewer bits (or other information-bearing units) than an un-encoded representation would use through use of specific encoding schemes. For example, this article could be encoded with fewer bits if one were to accept the convention that the word "compression" be encoded as "comp." One popular instance of compression with which many computer users are familiar is the ZIP file format, which, as well as providing compression, acts as an archiver, storing many files in a single output file.
