This is to remind you of the following ACM event. Once again, sorry for the delayed email.

- Durgesh, for ACM Mumbai

ACM Seminar Friday, June 29, 2001 - 6:30 p.m. Title: Data Compression Speaker: Sayyed S. A. A., NCST Venue: Lecture Theatre, NCST, Juhu

Abstract:Data compression techniques are applied to files to reduce their size, which in turn increases the capacity of data storage and speeds up data transmission. Data compression draws heavily from information theory, which deals with the probability of some symbol appearing in the input. For totally random sources, each symbol is equally likely, but random sources are uncompressible. This means that the more probable an event, the less information it contains. Data compression techniques also work on this principle. If we look at real-world files, we find a lot of redundant data in them. Data compression exploits this redundancy to its advantage. I intend to give an overview of data compression

About the Speaker: Mr Sayyed is a consultant in the Database and Knowledge Engineering division at NCST Juhu. His interests include Databases, compression and encryption.
