IP address

The IP address is a 32-bit number, which identifies each network user in the Internet or Intranet unambiguously. It consists of a network part (Net ID) and a user part (Host ID).

LAN – Local Area Network

Local network within a limited area using a fast transmission medium as e.g. Ethernet.

Router

Routers connect two different networks. Contrary to bridges, they do not decide on the basis of the Ethernet address but as a function of the IP address, which data packages have to be forwarded.

Switch

Switches allow – just like hubs – to connect several users in a star-type network. A switch “learns” the Ethernet address of the network user connected to a port and only forwards those data packages which are addressed to this network user. In addition to switches for 100BaseT (100 Mbits/s), there are so-called auto sensing switches, which detect automatically if the terminal equipment connected works with 10 or 100 Mbits/s.

TCP – Transmission Control Protocol

TCP is based on IP and does not only ensure the connection between the users during data transmission but also the correctness of the data and the right sequence of the data packages.
