handshaking is basically two computers ensuring they have a connestion over a network
to secure analog data is called scrambling in data communication
In digital communication we talk about signal while in data communication we talk about data and the could be in the form of packets or frames.
The transmission time formula is calculated by dividing the size of the data packet by the transmission rate of the communication system. This formula helps determine the time it takes for data to be sent from one point to another.

The 8251 A is a programmable communication interface used for serial data communication. Its primary functions include the conversion of parallel data from a microprocessor to serial data for transmission and vice versa for reception. It supports various communication protocols, provides error detection, and allows for configurable baud rates. Additionally, it facilitates the management of control signals and handshaking for effective data transfer between devices.
communication system are concerned with the transfer of data and information from one location to another
the data communication is like in which all working of networks through which we communicate each others.
A terrestrial system for satellite communication is one that facilitates. This includes the facilitation of audio, data, and any other communication.
communication system are concerned with the transfer of data and information from one location to another
By ensuring that data does not change during transmission
Effectiveness of data communication system depends upon three fundamental characteristics 1. Delivery 2. Accuracy 3.Timeliness. 1.Delivery : System must deliver data to correct destination. 2.Accuracy : System must deliver data accurately. 3.Timeliness: System must deliver data in correctly manner.

Its because the CPU must know whether the printer is free or not?
Simplex communication Unidirectional transmission.
Data Communication is the transmission of data (text, voice, etc) from one computer to another (or to a peripheral device). The four things needed are a sender, a receiver, a channel and a protocol.
