TYPES OF INFORMATION SIGNAL - Coggle Diagram
TYPES OF INFORMATION
SIGNAL
Data
store in computer or retrieve from it
carry information from 1 point to another
using codes electrical ,radio and light signal
email , file , web page
Digital Signal
non-continuous electrical signal
easy signal regeneration
Convertion are easy from decimal numbering system to binary and computer can readily store binary numbers
Binary values within data frame represent specific protocol information
Data Rate
correspond to the speed that digital signal
transfers data across wireless network
gives some insight on how
long it will take to send data from one point to another, identify
amount of bandwidth that medium must supply to support the signal
Throughput
more accurate way of representing the
true performance and efficiency of a network
The higher the throughput, the higher the performance
It usually includes actual information being sent across the network
ANALOG SIGNALS
a continuous signal whose characteristics
(amplitude, voltage or frequency) changes continuously over a period of time
EXP:light and human voice, radio waves
