KB (kilobyte) is a unit of digital information storage equal to either 1,000 bytes (10
3 ) or 1,024
bytes (2
10 ), depending on context.
Kbps (kilobits per second ) is a measure of bandwidth on a data transmission medium.
LGBT is an acronym that refers to the lesbian, gay, bisexual, and transgender community. Sometimes used to refer to anyone who is nonheterosexual.
MB (megabyte) is a unit of digital information storage equal to 10
6 (1,000,000) bytes.
MP3 (MPEG-1 Audio Layer 3) is a digital audio encoding format that compresses audio data by a
factor of 12 without losing noticeable sound quality.
P2P ( peer-to-peer) is a computer network that uses diverse connectivity between participants in
a network and the cumulative bandwidth of network participants rather than conventional centralized resources where a relatively low number of servers provide the core value to a service or
application.
Portal
1 if Web portal: is an online interface that allows Internet users to collect and view information
(e-mail, weather, stock prices, etc.) from various sources in a visually unified way.
1 if Intranet portal: is a single network-specific hub that provides unified access to information
and applications, often for a private company or organization.
Proxy (also Proxy server) is a server that acts as a go-between for clients (such as Web browsers
or other applications) and other servers. Proxy servers enable anonymous online activity and increase access speed through caching.
Reverse filtering (also known as Geolocational Filtering) is a practice that occurs on the Web
server hosting the content, as opposed to at a point along the way of the traffic flow, and is based
on restricting requests based on geographical location of the originating Internet Protocol address.
Copyright holders who want to restrict access to their content in certain markets often use reverse
filtering. Examples include hulu.com, BBC.com, and other sites that syndicate commercial video
and audio content that is subject to licensing.
SMS (short message service), also known as text message, is a communication service standardized
in the GSM mobile communication system, allowing the exchange of short text messages between
mobile devices.
Social networking sites are Web services that focus on communities of users with shared interests. Popular examples include Facebook, Twitter, MySpace, and Orkut.
TB (terabyte) is a unit of digital information storage equal to 1 trillion (10
12 ) bytes, or 1,000
gigabytes.
TCP/IP (Transmission Control Protocol/Internet Protocol) is the set of standards governing data
transmission over the Internet.
TCP/IP content filtering blocks communication on the basis of where packets of data are going
to or coming from, and not on what they contain.
