Thursday, 23 June 2011. System Unit,Input and Output and Secondary Storage. Is a process of varing one or more properties of high frequency periodic waveform- carrier signal. Contains information to be transmitted. Enable the carrier signal to transport the information in the modulation signal to some destination.

Saturday, June 25, 2011. Demodulation separates the original signal from the modulated carrier. A demodulator is an electronic circuit that used to produce a signal to alter and recover the modulated carrier wave. It is common used in connection with radio receivers, but many other systems use other different kinds of demodulators. Server is a computer or device on network that handles the request and sends it back to the clients through the internet.

Sunday, 26 June 2011. Modulation is a signal which gives the addition of information to an electronic signal carrier. The same as morse code which are invented for telegraphy and still used in radios . Demodulation process is basically the reverse process of modulation. Node is a connection point either a redistribution point or communication.

Sunday, 26 June 2011. Is a process of inflection high-frequency periodic waveform,in music it inflect the volume,pitch and sort to enable the signal to transport all the information in the modulation signal to a particular destination. Is a process to extracting the original content signal from a modulated signal. Commonly used in connection that relate to radio receivers and modem. Is a rate or amount of data that can be transfer in one time.
