What is Info?
Organization that provides some that means agreed upon by simply some guidelines
between tv-sender and device.
Former mate: 1000001
Types of Data
Photo, Text, Music, Video, and so on
Digital and Analog data
What is Communication? What makes it
Connection is the technique of exchanging data.
Process of communication:
Non Verbal(body language)
Example of Conversation Techniques:
Pigeon, Post, telephone, telegraph, mails, networks.
Cellular network, a radio station, VOIP.
Methods of conversation.
Face to face.
Data Conversation System
• Sound to Audio Signal
• key press to binary.
• Convert Temperature, Pressure, collection and so on to
Consists of brake lines to make the insight data indicators to a
• Carry tone signal from microphone to headset. Ex lover:
Coaxial Cable television for TV SET Signals.
• Twisted match for LAN.
• Fiber optic wire or lumination pipe which carries concept on light wave.
• Information can be converted to digital form may be used to make lazer diode ON and OFF.
• Applied in one point to an additional. It uses
Various other media
• SONAR ( Water as being a medium).
• Earth as a medium in electrical signal.
Sound is arbitrary, undesirable electric energy that enters the communication system via the conversing medium.
Does not carry any which means to the program.
Distorts the sent signals.
Types of Communication
Info and Signs
Takes on constant values. Ex girlfriend or boyfriend. Voice or perhaps video
Takes on discrete beliefs. Ex. Text message and integers
Continuously various voltage amounts representing data
carried on the variety of channel
Sequence of voltage signal representing data transmitted on the wire method. Voltage levels are predetermined and
Constant valued data over continuous time.
Can take unlimited no of values.
Data can be sent since signals of continuous electromagnetic wave. Used in hopes of transmitting info across a network.
Prone to EMI and mistakes more.
Analog technology records waveforms as they are.
All analog signals happen to be represented by utilizing sinusoidal
Case: Voice, Online video, Real time data
Discrete valued data over time.
Predefined voltage levels – M ary communication
Less vulnerable to noise....
