The computers on a local network can be large computers or personal computers, with different types of peripherals. Although there are many types of local networks among them there are some common characteristics:
All devices can communicate with the rest and some of them can operate independently.
The two basic types of devices that can be connected to a local network are workstations and servers:
'A workstation is a computer from which the user can access network resources.
-A Server is a computer that allows other computers to access the resources available. These servers include:
dedicated: they are only used to provide resources to other nodes
not engaged: they can work simultaneously as a server and workstation.
There's kind of a little special server that will be discussed separately, is the communications server. This server allows any of the computers on a network to communicate with external devices or systems. In turn, will be divided into two groups: bridges and gateways.
Generally, in a network node requesting a service or initiates communication, is called client. The node will respond to the request is called a server.
- A common communication medium through which all devices can share information, software and hardware, regardless of the physical location where the user or device is found. Local networks are contained in a small physical area: a building, campus, etc.
- A very high transmission speed so that it can adapt to the needs of users and equipment. The team from the local network can transmit data at the maximum speed that can communicate network stations, usually one Mb per second.
- A relatively short distance between stations between a few meters to several kilometers.
All devices can communicate with the rest and some of them can operate independently.
- A reliable system with a very low error rate. Local networks usually have their own system of detection and correction of transmission errors.
