Connecting two computers to a local network

A person who has only recently begun to comprehend the wonderful world of computer technology, it may seem that the connection of two computers is used only in offices, and at home it is not necessary. But this is a delusion. It is difficult to indicate all the features and benefits that connects two computers.

Many know that just a few decades ago the computer was the size of a large hall, weighed several tons, and its price was enormous. Nobody could think of buying such a car for home use. Decrease in Cost of computing devices has made science fiction a reality! Now the situation is very common when there are several computers in the family: the husband has a full-fledged personal system unit, his wife has a compact laptop, and the schoolchild's child has his own electronic assistant for the Internet, games and abstracts. It is often necessary to connect two computers to the network. After all, it allows you to exchange information without a drive and a flash drive. In addition, the connection of two computers is sometimes used to save on paying bills for the Internet - just connect the provider's cable to the router, hub or switch so that everyone can simultaneously access the network.

Connection of two computers can be performed in several ways. The easiest is through Ethernet network cards . On the motherboard of each modern PC there is an RJ-45 connector (the card is disconnected on the main board). In form, it resembles the usual connector for a telephone wire, only 1.5 times more. Two plugs are connected (twisted) to the twisted-pair cable conductors. One of They are included in the RJ-45 of one computer, and the other - in the connector of the second. After that, it remains in the operating system settings to enable access to resources and scan the network environment in My Computer. The working group should be the same. If there are more than two computers, then you can use a splitter. In this case, the wires from them are included in a special device-switch, which distributes the data streams.

In addition to the wired solution, there are analogs that use as a carrier medium not copper conductors, but radio frequencies. This is the famous Wi-Fi and Bluetooth. Their advantages are obvious - just connect the devices to computers, adjust the parameters, and you can work.

The disadvantage is the additional source of radiation, which is already more than enough in the modern world. Each user decides for himself how best to connect computers to the network.

Also except for Ethernet (RJ-45) interface can be used COM and LPT ports

On forums, it is often asked whether it is possible to connect two computers via usb. Yes it is possible. It is necessary to purchase a special USB Link cable in which the controller chip is mounted. Then connect the ports and use a special program to exchange data. Disadvantage: high cost, restriction on cable length, availability of more convenient alternatives (outdated solution), infrared and even modem connection.
