What is scrambling in data communication?
to secure analog data is called scrambling in data communication
How data communication and digital communication differ?
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.
What is the transmission time formula used to calculate the time taken for data to be sent from one point to another in a communication system?
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.
What are data communication terminologies?
data communication terminologies ther are many people distribute about computer
What is the purpose of data communication standard?
to enable data to be set
What is handshaking mode of data transceiver?
big europian org.
What are the functions performed by 8251 A?
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.
What is the communication system?
communication system are concerned with the transfer of data and information from one location to another
Fundamentals characteristics of data communication system?
the data communication is like in which all working of networks through which we communicate each others.
What is terrestrial system for satellite communication?
A terrestrial system for satellite communication is one that facilitates. This includes the facilitation of audio, data, and any other communication.
What is systemic communication?
communication system are concerned with the transfer of data and information from one location to another
How is accuracy achieved in an effective data communication system?
By ensuring that data does not change during transmission
What are the three fundamental characteristics of data communication system?
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.
When is the data communication system start or happen?
telegraph in early 1800s.
Why must data be sent to a printer on a handshaking basis?
Its because the CPU must know whether the printer is free or not?
What do you call a communication system in which Data cannot be sent in both directions at the same time?
Simplex communication Unidirectional transmission.
What is data communications and what four items are needed to make it work?
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.
