Local networks come in all sizes. They can range from simple networks
consisting of two computers, to networks connecting hundreds of
thousands of devices. Networks installed in small offices, or homes and
home offices, are referred to as Small Office Home Office (SOHO)
networks. SOHO networks enable the sharing of resources, such as
printers, documents, pictures and music between a few local users.
In
business, large networks can be used to advertise and sell products,
order supplies, and communicate with customers. Communication over a
network is usually more efficient and less expensive than traditional
forms of communication, such as regular mail or long distance phone
calls. Networks allow for rapid communication such as email and instant
messaging, and provide consolidation and access to information stored on
network servers.
Business and SOHO networks usually provide a
shared connection to the Internet. The Internet is considered a "network
of networks" because it is literally made up of thousands of local
networks that are connected to each other.
Review the different types of networks below.
Small Home Networks
Small home networks connect a few computers to each other and the Internet.
The Small Office/Home Office
The
Small Office/Home Office or SOHO network enables computers within a
home office or a remote office to connect to a corporate network or
access centralized, shared resources.
Medium to Large Networks
Medium
to large networks, such as those used by corporations and schools, can
have many locations with hundreds or thousands of interconnected
computers.
World Wide Networks
The Internet is a network of networks that connects hundreds of millions of computers world-wide.
