The Internet is a vast network of computers connected across the globe that can share both information and processing (Oz
and Jones, 2008). Information is transmitted from PCs whose users request services to computers that hold information
and host business applications that deliver the services in response to requests. The PCs within homes and businesses
are connected to the Internet via local Internet service providers (ISPs) which, in turn, are linked to larger ISPs with
connection to the major national and international infrastructure or backbones. The Internet can be described is as a
global network system made up of smaller systems. The Internet was conceived by the Defense Advanced Research Projects
Agency (DARPA), an American intelligence organisation, in 1969. The Internet began to achieve its current form in 1987,
growing from systems developed by DARPA and the National Science Foundation (NSF).
