Advantages And Disadvantages Of Data Communication

1)A network is when two or more computers are connected together and are able to share data and communication.

Communication is the sending and receiving messages and information between two or more people. The person receiving the information is called the receiver and the person sending the message is referred to as the sender. The information conveyed can include instructions, ideas, facts, concepts, beliefs, opinions and even emotions. Effective communication occurs if the receiver understands the exact information or idea that the sender intended to transmit.

Data is defined as useful raw material which is intended to be useful for both the originator and for the intended receiver. Data consists largely of facts and figures ideal for communicating the intended meaning. This data can be interpreted and can be categorised as follows;

It is generally limited to a geographic area such as a writing lab, school, or building. Rarely are LAN computers more than a mile apart. In a typical LAN configuration, one computer is designated as the file server. It stores all of the software that controls the network, as well as the software that can be shared by the computers attached to the network. Computers connected to the file server are called workstations. The workstations can be less powerful than the file server, and they may have additional software on their hard drives. On many LANs, cables are used to connect the network interface cards in each computer; other LANs may be wireless.

Computer Network: A LAN (local area network) that connects computers in a house, at school or at work.

Data communication is the exchange of data between a sender and a receiver of the information. The components data communication has to have, to be a data communication are:

data has to be, and what pieces of software computers need to have to send this kind of data.

A network is the way to communicating throughout the internet; also, it is connected to the group of computers that allow to sharing the information through a network. Not only that network is just for sharing the information though connected of group computers, but for internet that including social media, game online, telecommunication, programming that would be require network for professional career, and more that can be any in the real world, even that can be also for security throughout network to protect whoever uses network for personal and business. A network is a-must

Communication (from Latin "communis", meaning to share) is the activity of conveying information through the exchange of thoughts, messages, or information, as by speech, visuals, signals, writing, or behavior. Communication “is a fundamental aspect of all human relationships” and is an essential element of good care.

Data communication is when data is exchanged between a sender and a receiver. Data communication is made up of:

A network enables all PCs and devices to exchange data with each other which means they can all communicate with each other with information and data.

The word "data" may seem to be facts or numbers collected for future references and analysis of a subject that is being carefully examined, but data are pretty much used in all aspects of our lives. With these important facts and statistics, we can help an individual or a company reduce a significant amount of cost. These data can help companies such as Apple realized future growth potentials and where it can better maximize its income.

The Data link layer [also called layer 2] is responsible for moving a message from one computer or network device to the next computer or network device in the overall path from sender or receiver. It controls the way messages are sent on the physical media. Both the sender and receiver have to agree on the rules or protocols that govern how they will communicate with each other. A data link protocol determines who can transmit at what time, where a message begins and ends, and how a receiver recognizes and corrects a transmission error.

A computer network is a network that consist of two or more computers that are able to share information between them or their users. There are a large variety of different networks and the advantages or disadvantages are strongly related to the type of network we choose.

Advancements in the information technology sector have brought many benefits to the people all around the world.  Today with computer networking, we can chat, speak and see each other over a long distance. Data communication refers to the transmission of the digital signals over a communication channel between the transmitter and receiver computers. Communication is possible only with wired and wireless connectivity of the computers with each other.
