How is data communication done?
Data Communication is a process of exchanging data or information In case of computer networks this exchange is done between two devices over a transmission medium.
This process involves a communication system which is made up of hardware and software..
How is data communication measured?
While higher frequency can mean a faster system, a truer measurement of communication speed is bit rate.
Most data communications systems operate at millions of cycles per second, or megahertz.
In high frequencies, such as values in the MHz range, the time the cycle requires is measured in minute fractions of a second..
What are the 4 criteria of data communication?
The effectiveness of a data communications system depends on four fundamental characteristics: delivery, accuracy, timeliness, and jitter..
What do we study in data communication?
Data communications, sometimes called computer networking, is the system by which computers or other technologies are connected and share data.
One common form of data communications is the Internet.
Data communications is part of the electrical engineering discipline, but also relies on computer science principles..
- Data communication is the process of transferring data from one place to another or between two locations.
It allows electronic and digital data to move between two networks, no matter where the two are located geographically, what the data contains, or what format they are in. - Tasks of communication system Tasks of Communication System list are given below: Transmission System Utilization (Multiplexing) Interfacing Signal Generation (Codding) Synchronization between transmitter and receiver Exchange Management (Connection Management) Error Detection and Correction Flow control Addressing
- The IEEE 802.6 standard describes a MAN (Metropolitan Area Network) standard called DQDB (Distributed Queue Dual Bus).
The network is defined as a high-speed shared medium access protocol for use over a dual, counter-flowing, unidirectional bus networks.
