Apache

Apache is a freely available, and highly popular, open-source web server.

Originally, Apache was designed for Unix. Now versions are available for most operating systems including Windows, OSX and Linux. There are also numerous add-ons and tailored versions of the server using the Apache module API. The name Apache comes from its origins as a series of “patch files.”

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.

Hits

If anyone who isn’t a network engineer mentions “hits” to you, they’re probably trying to pull the cyberwool over your eyes. Hits are the individual requests a server answers in order to render a single web page completely. The page document itself, the various images on the page, any other media files embedded there – each of these items represents a separate hit. In other words, the more GIFs used in a page, the higher the hit count – so while hits may be a good indication of poor page design, they won’t tell you much about traffic.

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.
