Computing networking

LANs offer users several advantages, including shared access to devices and applications, file exchange between connected users, and communication between users via electronic mail and other applications.
A metropolitan area network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN).
The Internet is a global network connecting millions of computers. More than 100 countries are linked into exchanges of data, news and opinions. Each Internet computer, called a host, is independent. Its operators can choose which Internet services to use and which local services to make available to the global Internet community. There are a variety of ways to access the Internet, either through an online service like AOL or through a commercial Internet Service Provider (ISP).
Intranet is as "An infrastructure based on Internet standards and technologies that supports sharing of content within a limited and well-defined group." The "infrastructure" referred to the organizational and management infrastructure that created, managed, and shared the content. The physical network is based on the Internetworking Protocol (IP) like the Internet.

Intranet is as "An infrastructure based on Internet standards and technologies that supports sharing of content within a limited and well-defined group." The "infrastructure" referred to the organizational and management infrastructure that created, managed, and shared the content. The physical network is based on the Internetworking Protocol (IP) like the Internet.
Benefits of using a sub-net.

The question suggests usage of a subnet. A subnet is defined as a portion of a network that shares a common address component. On TCP/IP networks, subnets are defined as all devices whose IP addresses have the same prefix. For example, all devices with IP addresses that start with 100.100.100 would be part of the same subnet. Dividing a network into subnets is useful for both security and performance reasons. IP networks are divided using a subnet mask. Subnets connect to the central network through a router, hub or gateway. Addresses in the same subnet are reachable without going through a router, and thus can be reached by broadcast.
Minimising network congestion

Network congestion can be minimised by the usage of a router and sub-net as shown above. The sub-nets keep the traffic of a particular office within that network and only external information travels between the various sub-nets through the router for data access and through e-mail. Therefore this would minimise network traffic between the four offices and will keep the network traffic within a particular office within a sub-net. Therefore the use of routers and sub-nets assists in minimising network congestions. The router will route only data traffic and e-mails meant to be transported to other offices outside the sub-net.
