these technologies

TechnologyTechnology

Information can be stored and transmitted as either analogue or digital information

Analogue technologies are broadcast radio and television, traditional telephone, gramophone records, audio cassette players and, in health, X-ray machines and ECGs

Digital technology are computers, audio CDs, digital television, digital mobile telephone and, in health, CT scanning and MRI scanning

It is generally possible to convert information from analogue to digital..

A computer modem, e.g., connects a computer (digital) to the telephone network (analogue)

The modem converts the digital computer signal into an analogue signal for transmission (and then reverses the process at the receiving computer)

Telecommunication is moving towards digital signals:

audio, video, and other data can all be converted to digital signals and then transmitted through the same digital network

digital information can be transmitted more accurately; analogue information always degrades more the further it is sent

digital signals can be transmitted at extraordinarily fast rates

digital signals can be switched and routed more cheaply and flexibly than analogue/signals

Transmission:Transmission: Wires and cabling: telephone networks built

around copper wires and co-axial cables (the bandwidth depends on the type of cable or wire)

Fibreoptic cable: very fine glass fibres carrying digital signals as pulses of light (roll-out is expensive!)

Radio technologies: radio-waves based (low bandwidth and lack of reliability)

Microwave links (similar to radio with higher frequency; high bandwidth)
