Network In information technology, a network is a series of points or nodes interconnected by communication paths. Networks can interconnect with other networks and contain subnetworks.
Local Area Network (LAN) A local area network (LAN) is a group of computers and associated devices that share a common communications line or wireless link. Typically, connected devices share the resources of a single processor or server within a small geographic area (for example, within an office building). Usually, the server has applications and data storage that are shared in common by multiple computer users. A local area network may serve as few as two or three users (for example, in a home network) or as many as thousands of users (for example, in an FDDI network). See also: WAN and MAN
Wide Area Network (WAN) A wide area network (WAN) is a geographically dispersed telecommunications network. The term distinguishes a broader telecommunication structure from a local area network (LAN). A wide area network may be privately owned or rented, but the term usually connotes the inclusion of public (shared user) networks. An intermediate form of network in terms of geography is a metropolitan area network (MAN).
Metropolitan Area Network (MAN) A metropolitan area network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN). The term is applied to the interconnection of networks in a city into a single larger network (which may then also offer efficient connection to a wide area network). It is also used to mean the interconnection of several local area networks by bridging them with backbone lines. The latter usage is also sometimes referred to as a campus network.
Network Backbone A backbone is a larger transmission line that carries data gathered from smaller lines that interconnect with it.
Nodes In a network, a node is a connection point, either a redistribution point or an end point for data transmissions. In general, a node has programmed or engineered capability to recognize and process or forward transmissions to other nodes.

Why Computers and Networks?
Computers have become a necessity for all types of working environment. No matter what type of work you are doing, computers can help you in maximizing your work efficiency. Due to this fact computers are being used in all types of offices. Some areas like banking, insurance, stock exchange as well as reservation systems completely rely on use of Computers and Internet.
In a computing environment people need inter connectivity of computers to share resources like (files and data). It further helps in use and management of information collected through various nodes. These kinds of network that is being implemented in a particular organization are known as Intranets. Intranet helps in information sharing between different offices of same organization at different locations. It works on LAN (Local Area Network), MAN (Metropolitan Area Network) or WAN (Wide Area Network). There are mainly three ways of implementing different type of networks – wired, wireless or mixed (wired and wireless both as and when required).
Why Internet?
Internet is information superhighway, one of the major and accurate sources of getting information on any topic quickly. It is also used as backbone for implementing Intranet. Company’s websites and email are completely dependent on Internet. In brief, internet is the most important and fastest medium of communication in current hi-tech world.
Network Related Problems
As an end user you must have experienced various types of problems in your network during your work. Due to network downtime organizations have to bear loss of several productive working hours or in turn loss of revenue. Network downtime for your web servers may result unavailability of your website, in that case your potential viewers may not find required information through your website. It may create a negative impact of your company/organization or business
To deal with such problems immediately organizations need network diagnosis and maintenance experts to fix such problems to further reduce loss of productive working hours. However, it is not possible for every organization to hire a fulltime team of networking experts to solve their network issues. They prefer to rely upon network security consultants, who help them whenever needed. It’s a cost-effective alternative for organizations because they don’t have to hire full time professionals for taking care of their network troubleshooting needs.
