Subnet

A subnetwork, called a subnet, is a smaller part of an organization's network. Instead of all computers being linked together in a common loop that shares all tools and resources, smaller clusters of computer users might be grouped for these purposes. One advantage of a subnet is that it allows a company to get one network address. Otherwise, the company could get a separate address for each of the subgroups or individual users in the organization, which could use too many of the Internet's available network names. A subnet can be arranged geographically, for example, encompassing employees that work in the same building or office area. It might include those working on a specific project or any other type of grouping that lends itself to a cluster formation. When an information packet arrives, the router knows how to read the identification number by the subnet mask that screens the numbers below it. Subnets help to deconstruct a complex or oversized computer user group for easier access to the Internet, sharing utilities and tools, and greater focus on projects or documents. Instead of an unwieldy company attempting to manage an incoming packet or coordinate a stream of outgoing messages, a subnet can handle these tasks in a more linear fashion and in less time, making things happen more expeditiously for the company and for the recipient or the send of the message. Many companies are using subnets to deconstruct the complexity of their organizations. They also are willing to let smaller units manage local issues rather than treat them globally. This approach will help to ensure that things get handled in a timely manner, which will benefit all concerned. As the Internet continues to expand and evolve, more regional applications can be expected to enhance the many global processes that are already in place.
