How do computers communicate in a network?
Computer networks connect nodes like computers, routers, and switches using cables, fiber optics, or wireless signals.
These connections allow devices in a network to communicate and share information and resources.
Networks follow protocols, which define how communications are sent and received..

Advantages of computer networking
File sharing - you can easily share data between different users, or access it remotely if you keep it on other connected devices.
Resource sharing - using network-connected peripheral devices like printers, scanners and copiers, or sharing software between multiple users, saves money..

The U.S.
Advanced Research Projects Agency Network (ARPANET) was the first public packet-switched computer network.
It was first used in 1969 and finally decommissioned in 1989.
ARPANET's main use was for academic and research purposes..
What are the computer communication and network models?
There are three primary types of transmission modes based on the direction of exchange of information.
The first is simplex, followed by half duplex, and finally full duplex.
The Simplex transmission mode is used in computing networks when there is a single or one-way flow of information from sender to receiver..
What is a communication network?
A communication Network is a collection of methods that users employ to pass on valuable information.
The communication network is the sum of all the means and methods that an organization employs to communicate..
What is computer and communication network?
A computer communication network is an interconnection of a collection of several computers from which the user can select the service required and communicate with any computer as a local user..
What is computer network and communication?
Computers use common communication protocols over digital interconnections to communicate with each other.
These interconnections are made up of telecommunication network technologies based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies..
What is data communication and computer network?
Thus, data communication refers to the exchange of data between two or more networked or connected devices.
These devices must be capable of sending and receiving data over a communication medium.
Examples of such devices include personal computers, mobile phones, laptops, etc..
What is the main purpose of computer networks?
Computer networks are generally used to allow devices within the network to transmit, exchange or otherwise share information and resources with one another.
Networks may be set up to connect the devices within a home or business environment, all the way up to connecting a nationwide or global enterprise..
Why and where computer networks are used?
Uses of computer network :
Resource sharing: One of the primary uses of computer networks is to share resources, such as printers, scanners, and data storage devices.
This allows multiple users to access the same resources, which can help to reduce costs and increase efficiency..
