Bridge

A bridge (not to be confused with a router) is a data network device used to connect two network segments of different protocols.

For example, if you want computers on a TCP/IP network to talk to computers on a token ring network, you need a bridge to connect the two segments.

Event Handler

Event handlers are functions that handle client-side events.

Commonly used JavaScript event handlers include onClick, onMouseOver, and onLoad. When one of these events occurs – the user clicks on a link, for example – the event handler for that event will be executed.

Meta Information

Meta information means “information about information.”

In HTML, meta tags describe the content of the document in which they’re written. Meta tags have two possible attributes:
<META HTTP-EQUIV="name" CONTENT="content">
and
<META NAME="name" CONTENT="content">
. Meta tags with an
HTTP-EQUIV
attribute are analogous to
HTTP
headers that can control the action of browsers. Meta tags with a
NAME
attribute are used primarily by indexing and searching tools. These tools can gather meta information in order to sort and classify web pages. One way to help your document show up more frequently in search engines and directories is to use the
META NAME
attribute to set keywords that will pull up your site when someone does a search for those words.

Perl


Practical extraction and reporting language, or Perl, is a scripting language first created by Larry Wall to be used as duct tape for programming with the Unix operating system. Due to its immense power for handling piles of text and, consequently, as a common gateway interface (CGI) scripting language, Perl became very popular among server-side scripters. Perl has a large community of contributing programmers and, what’s more, costs nothing and is free to redistribute. These circumstances have helped Perl evolve from a scripting language used to generate server stats into a language many use for database administration. All along Perl has maintained its zaniness. Most Perl documentation reads as though written by early vaudeville comedians.

Solaris


A popular and widely-used flavor of Unix, Solaris (formerly named SunOS) is used for large-scale enterprise networks with tens of thousands of active nodes. Solaris is capable of distributed computing (using multiple computers’ processors to complete a single task) and symmetrical multi-processing (running two or more processors in one computer). The OS ships on Sun’s Sparc workstations along with graphical interfaces to increase user-friendliness.
