Answer:

At least need a hub Each machine is equipped with a network card 10-100M, with the network cable to connect all the machines to the hub of the network card, so that you can, if you want to access the Internet, you can find a telecommunications installation of a ADSL cat connected to the host computer network card On the dial-up Internet access, after sharing the network can be other machines through the LAN, but the host must have been connected to the network after the trip.
Respectively, is installed for the convenience of maintenance, side by side does not matter, the so-called AC electromagnetic effect due to the current line are twisted-pair has been the greatest degree of reduction. The distance between the requirements of the interval only the kind of grid that million-volt high-voltage line is needed, because the voltage is too large to prevent the air was breakdown of electricity, home improvement of 220 volts do not have to worry about this.
Office network must be online, and an ADSL telephone line, a ADSL cat (apply for ADSL will send a) router (with it not any host) a computer card, each computer a network cable (from the host even To the router), and then each computer running on the left side of the network neighborhood window set up a small family or office network on the OK.
