Network Definition And Explanation of Computer Networks
The generic term of ‘network’ defines a set of entities (people, objects ,etc.) interconnected with each other. A network allows you to circulate immaterial or material l elements between each of these entities according to well defined rules.
Network (in English network): all computers and devices connected to each other. Note that two computers connected together to them constitute only a minimum network. Networking (in English networking): implementation of the tools and tasks to link computers so that they can share resources of the network.
Depending on the type of entity concerned, the term will be so different:
- Transportation Network: A set of infrastructure and allowing to transport persons and goods between various geographical areas
- Telephone network: infrastructure to circulate between several telephones
- Neural network: set of interconnected cells between them
- Crime Network : set of crooks who are in contact with each other (a crook cached usually another!)
computer network Definition: a set of computers connected through physical lines and exchanging information in the form of digital data (binary values, i.e. in the form of signals that can take two values: 0 and 1)
A computer network can serve several different purposes:
- The sharing of resources (files, applications, or hardware, internet connection, etc.)
- Communication between people (e-mail, discussion online, etc.)
- Cross-process communication (between industrial computers for example)
- The guarantee of the uniqueness and universality of access to information (network database)
- The multiplayer video game
The networks also allow to standardize applications, generally referred to groupware to qualify the tools allowing multiple people to work in network. For example e-mail and group agendas to communicate more effectively and more quickly. Here is an overview of the benefits of such systems:
- Reduction of costs through shared data and devices,
- Standardization of applications,
- Access to data in a timely manner,
- Communication and more efficient organization.
Today, with the internet, there is a unification of the network. Thus, the interests of the establishment of a network are multiple, whether for a company or an individual.
Similarities between different types of networks
- The different types of Computer networks usually have points in common:
- Servers: computers that provide shared users by a network server resources
- Customers: computers that access to shared resources provided by a network server
- Connection support: determines how the computers are connected in
