How is a network structured?
A computer network can either only be used between two computers or it can also be used through a router. Such a network is usually set up according to the general LAN topology and all computers are linked together in a larger network with equal rights.
General and understandable information
- Of course, a professional explanation is a lot more detailed, but is next to not understood by most beginners. For this reason, simple terms and only the most necessary technical terms should be used in the explanation. A network that has a classic structure is usually a LAN (Local Area Network). Such networks are used in most companies and, of course, in many people at home.
- There are usually plenty of reasons for a LAN, and this also has a number of advantages. the computer are networked with one another and can communicate with one another. Networking can also be used, for example Internet access realize on several computers. The most important terms you should know about a LAN are: router, Ethernet or RJ45 cable, IP address, server and client.
This is how the network is built up in the classic way
- Networks do not necessarily have to be connected to the Internet, but it is usually common for all computers to have Internet access. For this reason, the modem is included in the network and installed near the router. The most important device with most of the tasks is the router, a kind of distributor that the communication between the individual computers. The router is connected to the modem via the WAN port and can therefore dial into the Internet.
- There are several LAN inputs on the back of the router and Ethernet cables are connected to these. The other end of this cable plugs into the computer's network card. In addition to the physical networking, it is also necessary in the software set the most important parameters. The router should ideally take on the role of a DHCP server and automatically assign IP addresses to the individual computers. All computers in this LAN can now exchange data with one another or access the Internet. Often a particularly powerful computer is also used, which takes on the role of a server and acts, for example, as a data storage device.
