Glossary of Internet terms Part-P/R

P

Pageview

The display of a web page by a user agent. Counting the total pageviewsoffers a good measure of web site popularity.
Password
A secret text snippet that allows a user to access a restricted area, upgrade
software, and other uses. A good password should be a hard to guess
combination of upper and lower case letters, numbers, and special characters at
least 10 characters long. You should use a different user name/password
combination for each account that has value to you.

PC
Personal Computer. A general term for IBM-compatible computers running the
Windows operating system. The term is historical; IBM no longer manufactures
personal computers.
PDF
Portable Document Format. An Adobe Acrobat proprietary file type; these files
are cross-platform (Windows and Mac OS) and are useful in electronic
publishing, prepress, and information sharing.
PERL
Popular Extraction and Report Language. Designed for processing text, this
popular programming language is also used for creating interactive web sites.
Permalink
Formed by combining the words permanent and link, a permalink is a link that
points to a specific blog post rather than to the page where the original post
occurred (since that page may no longer contain the posting).
PHP
PHP is a programming language for creating web server software that
interacts with HTML. PHP code is read and processed by the web server software
instead of by the web browser software on the user’s computer, as with HTML.
Pixel
A pixel is the basic unit of programmable color on a computer display or in a
computer image.


Plug-in
A program that is not part of the original software. For example, Macromedia
Flash, Real Audio, and a number of other companies have browser plug-ins to
make web sites more interactive. Also refers to components added to software
programs such as Corel Paint Shop and Adobe Photoshop that extend a
program’s capabilities.

Podcasting
Formed by combining iPod and broadcasting, a podcast is a form of audio
broadcasting via the Internet.
POP OR POP Account
Post Office Protocol. An email account for sending and receiving email. When
email is sent to a POP account, the mail is stored on the server until the user
logs in with their email software and downloads it. (Same as Email POP and POP
account.)

Protocol
Specific rules governing how data is exchanged between two electronic
devices.
Public Domain
Works in the public domain are available to the public at no charge because
their copyrights, trademarks, or patents have expired or somehow been nullified.
This may include information on government sites. This does not include
information that is publicly visible on private or commercial web sites. Just
because it’s there, does not mean you may copy it for your own site or
publications without permission from the copyright holder.

R

RAM
Random Access Memory. The most common type of memory used by
computers and other devices. The "random" part means that any byte of
memory can be accessed without touching the preceding bytes. RAM is
commonly known as the amount of memory that is available to programs.
RealAudio/RealVideo
RealMedia technology that allows you to stream audio and video from your
site.

Registrar
A company or organization that registers domain names. In the early days of
the Internet, Network Solutions was the only domain name registrar, but
competition for registrars opened up in November 1999. Nowadays there are
well over 100 registrars globally. ICANN is the new governing body for registrars.
Relative Address
An Internet address defining the path to a file within a domain (rather than
using the full Internet address). A link to a page within your own site can use a
relative address rather than an absolute address. This will speed up the load
time of your pages because the user’s browser doesn’t have to go back to a DNS
server to locate your site all over, which it does when internal links use an
absolute address.
Remove List
A file containing the email addresses of those who have asked to be removed
from a mailing list.
Resolution
The number of pixels per inch that an image is saved with or that a monitor
can display.
Router
On the Internet, a router is a mechanical device or software that determines
the network path a data packet should be sent to in order to reach its
destination.
RSS
Real Simple Syndication. RSS is a protocol for the syndication and sharing of
content. Also sometimes called Rich Site Summary.
