TRANSMISSION OF DIGITAL INFORMATION, e.g. TELEGRAPHIC COMMUNICATION

Scope Notes

Glossary: Circuit switching A system in which a communication path is physically permanent during the communication. Packet switching A system in which information is divided into discrete data units, characterised by a data payload and an address part known as a header part. The data units are able to travel over different communication paths to the destination. Message switching systems A system in which a message is sent into a network with the address of its destination added and it is routed to its destination through the network, e.g. electronic mail network systems. Hybrid switching Combinations of different switching systems (e.g. packet switching systems and circuit switching systems). Gateway gateways Arrangements for connecting between networks having different types of switching systems. | Limiting references: Interconnection of, or transfer of information or other signals between, memories, input/output devices or central processing units Interprocessor communication using networks
