TEK

Very useful project - TEK , which stands for Time Equals Knowledge, is an email-based system designed to
deliver Web content to users in low-bandwidth and low-connectivity environments. The system has
three components. First, the TEK Server evaluates pages for relevant content, and performs clientspecific
selection, filtering, and compression of pages to improve the information density of the results.
Second, and most importantly, an asynchronous communication protocol allows users to interface with
the TEK Server using email instead of a full-fledged TCP connection. Third, the TEK Client provides
a user-interface that is integrated with a Web browser, thereby emulating the look-and-feel of the Web
even though e-mail is being used as the transport mechanism.
