you will find a comprehensive glossary of Internet and Computer terms with definitions that are helpful and easy to understand.
To find a term, click the letter of which the word begins with and scroll
alphabetically to find your term. For example, to find the definition for the
word "Media", click the letter "M", then scroll the list
alphabetically until you find "Media".

Developed by Microsoft for its Windows operating systems. The icon for the
ODBC is named "Data Sources" and is located in the Control Panel under
Administrative Tools in the Windows 2000 and XP operating systems. This Data
Source Administrator is responsible for managing database drivers and
configuring the user and system Data Source Names (DSN). A UNIX system does
not use this method, its data source information is stored in text

The quality that defines how much light passes through an objectís

The most important program that runs on a computer. Every
general-purpose computer must have an operating system to run other
programs. Operating systems perform basic tasks, such as recognizing input
from the keyboard, sending output to the display screen, keeping track of
files and directories on the disk, and controlling peripheral devices such
as disk drives and printers.
For large systems, the operating system has even greater responsibilities
and powers. It is like a traffic cop -- it makes sure that different
programs and users running at the same time do not interfere with each
other. The operating system is also responsible for security, ensuring that
unauthorized users do not access the system.
Operating systems provide a software platform on top of which other
programs, called application programs, can run. The application programs
must be written to run on top of a particular operating system. Your choice
of operating system, therefore, determines to a great extent the
applications you can run. For PCs, the most popular operating systems are
DOS, OS/2, and Windows, but others are available, such as Linux.
As a user, you normally interact with the operating system through a set of
commands. For example, the DOS operating system contains commands such as
COPY and RENAME for copying files and changing the names of files,
respectively. The commands are accepted and executed by a part of the
operating system called the command processor or command line interpreter.
Graphical user interfaces allow you to enter commands by pointing and
clicking at objects that appear on the screen.

To run a microprocessor faster than the speed for which it has been
tested and approved. Overclocking is a popular technique for eking out a
little more performance from a system. In many cases, you can force your CPU
to run faster than it was intended simply by setting a jumper on the
motherboard. Overclocking does come with some risks, however, such as
over-heating, so you should become familiar with all the pros and cons
before you attempt it.
Overclocking is sometimes called speed margining.
