All About Computer Networking
Computer networking is the process of connecting computer devices together with hardware and software that supports data transmission across the devices. Hardware devices that make up computer networking often include computers, printers, servers, scanners, and faxes.
Computer networks allow you to share files and other resources with co-workers, customers, family, and friends. Computer networks can be simple home networks with just a few personal computers or a business network with hundreds or thousands of clients. In a business environment, computer networking allows users of the network to save and share data from and to central locations which is usually located on a server.
Computer networks use software called an operating system that helps run their programs. Operating system software can run on laptop computers, desktop computers, cell phones, network routers, and other devices. An operating system can provide basic networking support for Ethernet, WI-Fi, Bluetooth, and other wireless protocols.
Before the popularity of computer networks, users were only able to share data on floppy disks or external hard drives. With computer networking users of a network can copy over large amounts of data, and save files to a central location that is usually backed up by a network administrator.
Types of Computer Networks:
A local area network is a computer network that connects computers and devices in an area such as an office building, school, home, computer lab, or group of buildings that are close in proximity.
Home computer networking usually involves a residential local area network which is used for communication between devices in the home, usually a small number of computers, printers, and/ or mobile devices. Computer networking is an affordable way to connect computers, printers, and other devices in order to share files and the devices.
Wide area networks involve computer networking between offices that are located longer distances from each other such as cities or even countries. Telephone carriers, telephone lines, cables, and air waves are a few of the communication factors involved in a wide area network. Routers are usually placed between the offices that allow connections and communication between the offices. Larger computer networking allows the networks to share files, printers, and send and receive email.
The Internet is an example of a very large computer network and is often referred to as the "cloud." The Internet is a world-wide system of interconnected academic, public, governmental, corporate, and private computer networks. The Internet is the communications backbone that is fundamental to the World Wide Web.
The two main types of computer networking are wired and wireless. Wired computer networks are connected using a cable, such as an Ethernet cable, to a device such as a router. Wired computer networking is usually faster and more reliable than wireless.
Domains are for larger networks. A client-server model of a domain involves a server that is used for a central location for managing and configuring printers, users, and permissions on the network.
Hardware for Computer Networks:
Communications media is not the only thing that computer networks need; computer networks must have some basic hardware such as network interface cards. Networks must also have at least one of the following: router, switch, hub, or bridge.
