Data Binding

As a computer science term, data binding is the substitution of a real value in a program after it has been compiled.

For example, during compilation a compiler can assign symbolic addresses to certain variables or instructions. When the program is bound, or linked, the binder replaces the symbolic addresses with real machine addresses. The moment at which binding occurs is called “bind time” or “link time.” In dHTML, data binding allows the client to look into a database and retrieve the content. This data can be automatically displayed in your table using the HTML data binding extensions, or you can manipulate the data with a script.

DHCP

The dynamic host configuration protocol (DHCP) is an addressing protocol for TCP/IP networks.

IP addresses are leased to individual computers on the network from a DHCP server. DHCP allows users to move to different locations on a network without having to bother a network administrator (and they hate being bothered) to manually assign a new IP address. DHCP is useful in homes with several computers sharing a single high-speed internet connection.

DSL

A digital subscriber line, or DSL, is a communications technology that allows data to travel at very high speeds over standard telephone wire without interrupting normal telephone service.

The primary market for DSL is the home office since the technology makes it easy for residential homes to receive high-speed internet access at a reasonable price. DSL speeds, on the average, run at about 600kbps for downstream and 128kbps for upstream.

HTTP

The conversation between browsers and servers takes place according to the hypertext transfer protocol, or HTTP.

Written by Tim Berners-Lee, it was first implemented on the web in 1991 as HTTP 0.9. Currently, web browsers and servers support version 1.1 of HTTP. It supports persistent connections, meaning that once a browser connects to a web server, it can receive multiple files through the same connection.
