the data communication is like in which all working of networks through which we communicate each others.
communication system are concerned with the transfer of data and information from one location to another
The scope of work and the educational requirements are the difference between data communication and data communication information.

Data communication networks can affect businesses by being the foundations for distributed systems in which information system applications are divided among a network of computers. Data communication networks facilitate more efficient use of computers and improve the day-to-day control of a business by providing faster information flow. They also provide message transfer services to allow computer users to talk to one another via electronic mail.
communication media are the physical components through which the communication devices transmit data. e.g. cables, telephone lines, terminals.

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.

Some of the characteristics of enterprise data include the ability to create precise data, as well as the ability to quickly and efficiently retrieve said data. This can apply to both applications and communication.
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 depends upon three fundamental characteristics which are: 1->delivery:source system must deliver data to the desired or correct destination. 2->accuracy:source system must ascertain that the data is delivered accurately. 3->timeliness:the source system must ascertain that the data is delivered in a correctly or timely manner. apart from this effectiveness of data com. can be also related to the speed of data exchange.

Structured organization of data: Data is stored in tables with defined relationships. Data integrity: Database systems enforce rules to maintain accuracy and consistency of data. Query processing: Allows users to retrieve and manipulate data using SQL queries. Concurrency control: Manages access to data to prevent conflicts in multi-user environments.
