The telecommunication industry includes satellites, closed computer networks, and wireless networks.
- A telecommunications network is a group of terminal nodes, any intermediate nodes, and links that are connected to enable telecommunication between the terminals.
- These transmission links between them connect the nodes.
- The nodes use different types of switching such as circuit switching, message switching, or packet switching to pass the signal through the right links and nodes to reach the right destination terminal.
- Each terminal in the telecommunication network usually has a unique kind of address so that the messages or connections will be routed to the right recipients.
- The collection of addresses within the network is named the address space.
