DoS attack (denial of service attack) is an attempt to prevent users from accessing a specific computer resource, such as a Web site. DoS attacks (sometimes called DDoS, or distributed denial of
service, attacks) usually involve overwhelming the targeted computer with requests so that it is
no longer able to communicate with its intended users.
DSL (digital subscriber line) is a family of technologies that provides digital data transmission over
existing telephone wires.
EDGE (Enhanced Data rates for GSM Evolution) also known as EGPRS or Enhanced GPRS is a GSM
extension that improves data transmission rates by up to three times their original speed.
GB (gigabyte) is a unit of digital information storage equal to 10
9 (1,000,000,000) bytes. However,
this term is also often used to mean 1,024
3 (1,073,741,824 bytes).
GPRS (general packet radio service) is service for mobile devices that divides data into packets for
transmission purposes. It can be used with 2G and 3G wireless telephone technology operating
on the GSM standard.
GPS (Global Positioning System) is a free global navigation satellite system that is used for both
military and civilian purposes.
GSM (Global System for Mobile communications) is a digital mobile phone standard used by as
much as 80 percent of the global market. Its widespread use enables international roaming among
different mobile phone operators.
HTTP (Hypertext Transfer Protocol) is a set of standards for exchanging text, images, sound, and
video by means of the Internet.
HTTP proxy filtering blocks communication on the basis of the specific HTTP address or URL
being requested.
ICP (Internet Cache Protocol) is a set of rules used to coordinate Web caches (places where duplications of online data are temporarily stored, enabling faster access and reducing bandwidth).
ICP (Internet content provider) is an online service provider that creates or provides informational,
educational, or entertainment content.
ICT (information and communication technology) is an umbrella term that includes all technologies
intended for the manipulation and communication of information.
IP address (Internet protocol address) is a numerical identification assigned to devices participating
in a computer network utilizing the Internet Protocol.
ISP (Internet service provider) is a company that provides users with access to the Internet.
IT (Information technology) describes the use of computers, computer software, and other communications technologies to create and manage information.
