You can often hear: something or someone somewhere is working locally. This concept requires clarification. Let's look at the meaning of the word "local" in terms of networks.
general information
When they say "locally" - this means thatprocesses are carried out in a small area of one structural unit. An example is a private home or business. In the first case, a local computer will include a stationary computer, a laptop, smartphones and tablets. In the second variant, all computers, which are used to simplify the conduct of activity, are meant by it. So, in addition to the previously listed computer technology, the local network can include microcontrollers, sensors, network cards of control devices and so on. Due to the characteristic features, the computer is divided according to their purposes. As a result, a local subsystem is created, which is looped on performing a certain range of tasks. Let's look at how such networks function. Attention will be paid to the two most important areas.
Local working network for people
In this case,technique, with which a person works. A local area network can have a "management" center in the form of a server. But his presence is not necessary for functioning. When they say in this case "locally" - this implies the unification of all computers and mobile devices at home, office or enterprise, with which a person can work directly. For clarity, consider this example. There is a big company. In its framework, there is a department of supply, sales, advertising and accounting. The first three order the necessary materials, while information about them is driven into the computer, which sends it to the server in the database. When the accounting department will need to calculate the movement of funds for the enterprise, they turn to it. If we consider a home network, then in this case locally - this is when you can direct the work of all equipment to fulfill one specific goal. For example, if there are two stationary computers, then two people can play one game in the command mode (if it is provided in the program itself). Also, one can connect to the desktop of the other and perform the necessary actions there (for example, restore the computer if it is out of order).
Local network of machines
This, as a rule, can be seen at the enterprises. But similar communications are offered both by the clever house, and other computerized objects. The essence of this local network is that it unites a large number of boards, sensors, various mechanisms and devices in order to obtain performance in a certain direction. So, the automated assembly line of the enterprise should collect quickly, qualitatively and, most importantly, without respite products, to which the company trades. A smart house should organize the interaction of all its components in such a way as to provide the person with the highest level of comfort.
