The most incredible article about Basics of Networking you'll ever read

Networking is the process of connecting two or more computing devices with each other for sharing data. Computer networks are constructed using hardware and software.

Area Networks

Computer networks are categorized in various different ways. According to one approach the networks are defined on the basis of geographic area which it covers.

Local Area Networks( LANs) is used to connect  a single home, small office building, school whereas wide area network(WANs) is able to connect cities, states or more wider areas. Internet is considered as world largest public WAN.

Network design

Computer networks can also be defined on the basis of design approach. The two most common form of network design are client/server and peer to peer. Client server network comprises centralized server computer that can store email, files, web pages and applications. On the other hand in a peer to peer network, all computers will be able to support the same functions. Client server networks find its application in business whereas peer to peer networks are most commonly used in homes. 

A network topology defines its structure and layout from the point of view of data flow. In bus network, for example, all the computers communicate and share across one common conduit. While in a star network all the data flow takes place through one centralized device.

Common network topologies are bus, ring network, star and mesh networks.

Network Protocols

Computer devices use communication languages which are called network protocols. The set of protocols that computer network support is another way to classify them. Networks often use multiple protocols and each of them supports specific applications. One of the popular protocol is TCP/IP which is also the most common protocol found on the internet and in home networks.

Home Networking

Home Networks are managed by ordinary homeowners with little or no technical knowledge. Broadband router hardware produced by various manufactures has been designed to simplify home network setup. With the help of home broadband routers; devices in different rooms can efficiently share a broadband internet connection and that allow people to easily share the files and printer within a particular network and increase overall network security.

Home networks have grown with each generation of new technology. Earlier people commonly use home network to connect a few PC, and share some of the documents, but now there is increased usage of network game consoles, smart phones for streaming video and sound and digital video recorders. Home automation systems have grown in popularity with arrival of practical system for controlling lights, appliances and digital thermostats.

Business Networks

Often businesses require an additional communication, security and data storage therefore a business network contain multiple LANs. Companies with large set up uses wide area networking to connect various branch offices together. Voice over IP communication, back up technologies and network storage are most common in businesses. Some of the big companies also have their internal websites called intranets for connecting to other employees.

Internet and Networking

Computer networking has gained immense popularity with the introduction of World Wide Web (www) in the 1990s. Public web sites, peer to peer file sharing systems and a large no. of services run on internet servers all over the world.

Wired and Wireless Networking

Most common network protocols like TCP/IP, has its efficiency in wired and wireless networks. Networks with Ethernet cables are more commonly used in businesses, homes and schools for the several decades. Wireless networking has emerged as the popular technology for building new computer networks which include smartphones and other wireless gadgets that have contributed to the rise of mobile networking.
