Applet

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.”

Read Webmonkey’s Apache for Beginners article for more details about Apache.

Information and downloads can be found at the Apache Software Foundation website.

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.

ISO Entities

ISO (International Standards Organization) entities, sometimes referred to as character entities, are a group of ASCII characters that can be used in HTML to display special characters. For example, you can’t simply type the registered trademark symbol ® from your keyboard since it’s not a standard ASCII character; it’ll show up as garbage on your web page. But if you use the ISO entity equivalent, the web browser will be able to interpret the character correctly.

For example, the umlaut ¨ appears if you write
¨
in your HTML code.

MIME

Defined in 1992 by the Internet Engineering Task Force (IETF), multipurpose internet mail extensions, or MIME types, are a specification for formatting non-ASCII messages so that they can be sent over the internet.

When a browser comes across a file in an HTML document with a MIME extension (like .gif), the browser knows to display that file as an image. Many email clients also support MIME, enabling them to send and receive embedded media via the internet mail system.

Scripting Language


A scripting language is a simple programming language used to write an executable list of commands, called a script. A scripting language is a high-level command language that is interpreted rather than compiled, and is translated on the fly rather than first translated entirely. JavaScript, Perl, VBscript, and AppleScript are scripting languages rather than general-purpose programming languages.
