Computer Networks
A computer network is made up of several computers that are linked to one another in order to share and receive resources. A computer, printer or any other device that can send or receive data can be considered a node. Communication channels are the linkages that join the nodes.
Distributed processing, which divides a task among multiple computers, is used by computer networks. Rather, each distinct computer completes a portion of the task that is handled by a single computer.
Uses of Computer Networks
A computer network can be used for many different purposes, such as:
Communication
Via computer networks, people and groups can work together via email, chat, and video conferencing, among other communication channels.
Remote access
By enabling information to be accessed from any location in the world, network technologies release the power of knowledge and support. As a result, this gives users greater comfort and freedom of operation.
E-commerce
Businesses may sell goods online and process safe payments thanks to computer networks, which facilitate online sales and payment processing.
Resource Sharing
By enabling users to share data, printers, and scanners, these bags are a blessing that will enhance productivity and cut expenses.
Entertainment
Online gaming, social networking, online streaming of movies and music, and other forms of entertainment all make use of networks.
Types of computer networks
- Local Area Network
- Wide Area Network
- Metropolitan Area Network
1. Local Area Network
The most popular kind of networks are local area networks, or LANs, which let users connect to a shared network within a short radius and share resources. A LAN might be used, for instance, when you connect your laptop to your home internet and print a document from a networked printer.
2. Wide Area Network
Wide Area Networks, or WANs, are large, non-geographic networks that corporations and multinational businesses use to create a common network with widespread connectivity. One use case for WANs is when employees who work remotely use the internet to access corporate data.
3. Metropolitan Area Network
A metropolitan area network, or MAN, is a medium-sized network. Although a MAN is an expensive network, it offers effective device connectivity over a large geographic area.
