https://doi.org/10.1057/9780230601802Asynchronous transfer mode (ATM) has been developed mainly by the telecommunications companies and is proposed as a standard for Broadband ISDN. It was independently developed by Bellcore, the research arm of AT&T in the USA, and several giant telecommunications companies in Europe. This has led to two possible future standards.

Thyroxine

Janina Brutt-Griffler,Catherine Evans DaviesInformation is transmitted as an energy from a source to a destination. This energy can take the form of light waves, radio waves or even sound waves. Any electronic signal can be analyzed either in the time domain or in the frequency domain. All electrical signals, no matter their shape, can be represented by a series of sine or cosine waves.

Janina Brutt-Griffler,Catherine Evans DaviesOne the greatest revolutions in data communications is the usage of light waves to transmit digital pulses through fibre optic cables. A light carrying system has an almost unlimited information capacity. Theoretically, it has more than 200 000 times the capacity of a satellite TV system.

Data communications models, networks and standards,A local area network (LAN) is a collection of computers within a single office or building that connect to a common electronic connection — commonly known as a network backbone. A LAN can be connected to other networks either directly or through a WAN, as shown in Figure 2.1
