The use of computers developed and became used both in businesses and homes, and it became one company, and sometimes one house includes more than one computer, where companies carry out and save business on computers, and with the expansion of some companies and the diversity of their businesses, the company shows the need for more than one computer and But at the same time, you need to link these devices so that information can be easily transferred between devices without the need to obtain paper copies to continue the work, and here the need for networks that combine these devices with each other appeared, and with progress, communication between devices became easy That is, even if these devices are in different countries, using or without Internet technologies, if they are in one place.
How are interconnection networks made?
To make a network link between two or more computers, it can be done with or without the Internet.
Network work without the presence of the Internet.
1- Needs.
• Computers provided that they contain a port or a place for a (LAN) card or network card.
• Switch, which is the device that is used to connect devices, and devices with 8 or more outputs are available.
• The connection cable, and in this type of network, (Twisted Pair Cable) is used.
• The head of the cable or the clips, which are made of plastic, and we need for each connecting cable 2 from the head of the cable.
• Araja or a tool for cutting and installing wires, which is the tool that is used to install the connecting wire in the cable head. Twisted Pair Cable-OptimizedCable head-OptimizedTop cable installation tool-Optimized
2- Installing a LAN card in each network device and defining the card.
3- Begin to prepare the connection cables, where you use the araga to expose the two ends of the connection wire, where the plastic outer layer that covers the internal wires is removed, which is a group of colored wires consisting of 8 wires of different colors.
4- Cut the end of the wires so that they are flattened and make all the ends of one length.
5- Arrange the wires according to the correct shape from right to left (white-orange, orange, white-green, blue, white-blue, green, white-brown, brown), then insert them into the head of the plastic cable, and to fix the wire in the head, use the brackets that are pressed to be installed.
6- The process of installing the cable head is done at both ends of the connection cable, and thus the manual or hardware work is finished. Only the two ends of the connection cable between the switch and the devices are installed.
7- Open the computer, then from the (Star) menu, enter the (control panel) and from it to (My Network Places) and then go to the option ((Set up a home or small office network), which is an option found in the existing menu On the left of the page, and here the steps will be arranged where a window opens, click on next, then (next), in the new window, click on the second option, then (next), now put a name for the device, then a name for the group, then mark the first option Then wait for a while and click on (next), from the new window choose the last option and click (next), go back again to (My Network Places) and from there to the (Properties) option, then click on Internet Protocol (tcp/ip)) where you click twice with the mouse, after that the (ip) is entered and the same steps are followed with the rest of the devices, and it is taken into account when entering the (ip) number in the rest of the devices, only the last number is changed.
network if there is internet.
1- Steps 1 to 6 are done as they are with regard to preparing cables and cable heads.
2- Restart the computer and then go to (Network Connections) and here you will find a new connection. To prepare the network settings, contact the service provider so that he tells you how to configure your router, then follow the same steps (Set up a home or small office network) and share files with other parties.
3- Take care that there is an outlet for the modem or internet connection in the network switch, and in this case it is usually the router.
4- The network can be done without wires or connection cables with the same steps, except for cables and cable heads, and by using a router or a wireless switch.
