The Internet: The Largest Network of All
With the meteoric rise in demand for connectivity,
the Internet has become a major communications highway for millions of users.
It is a decentralized system of linked networks that are worldwide in scope. It
facilitates data communication services such as remote log-in, file transfer,
electronic mail, the World Wide Web and newsgroups. It consists of independent
hosts of computers that can designate which Internet services to use and which
of their local services to make available to the global community.
Initially restricted to military and academic
institutions, the Internet now operates on a three-level hierarchy composed of
backbone networks, mid-level networks and stub networks. It is a full-fledged
conduit for any and all forms of information and commerce. Internet websites
now provide personal, educational, political and economic resources to
virtually any point on the planet.
Intranet: A Secure Internet-like Network for Organizations
With advancements in browser-based software for the
Internet, many private organizations have implemented intranets. An
intranet is a private network utilizing Internet-type tools, but available only
within that organization. For large organizations, an intranet provides easy
access to corporate information for designated employees.
