Computer Network :: Definition And Types of Computer Networks

Understanding Computer Networks
Understanding computer network is a combination of two or more computers interconnected by a media through wired or wireless network so that these computers can share resources and exchange of communication. All network based on the concept of sharing (sharing). As the development of computing technology, information and communication a personal computer models that serve the entire computing tasks an organization has now been replaced by a group of computers that would separate but interconnected in carrying out their duties, such systems are called computer networks (computer network). Computers included into a computer network can share resources such as:

1. data
2. printer
3. Internet
4. Etc.

TYPES OF COMPUTER NETWORK
The types of computer networks is divided into three classifications, namely the Local Area Network (LAN), Metropolitan Area Network (MAN) and Wide Area Network (WAN). The thing that distinguishes this is just the type of network coverage area or location of the network. Local Area Network (LAN) Local Area Network (LAN), a privately owned networks within a building or campus-sized to several kilometers. LANs are often used to connect personal computers and workstations in a corporate office or factories to use shared resources (eg printers and scanners) and exchange information Metropolitan Area Network (MAN) Metropolitan Area Network (MAN), essentially a version LAN are larger and typically use the same technology to the LAN. MAN can include corporate offices are located adjacent or also a city and can be used for private purposes (private) or the public.

MAN is able to support data and voice, can even be associated with the cable television network. Wide Area Network Wide Area Network (WAN), the range covers a wide geographical area, often covering a country or even continent. WAN consists of a collection of machines intended for running programs (applications) user. But in general, and at this moment practically we know there are two types of networks: LAN and WAN. The main advantages of network sharing directly feels it is a global Internet, because the Internet core itself is a series of computer (thousands and even millions of computers) that are connected to each other. Evolved and developed over time, thus forming a complex network as we feel today. Similarly, article glance understanding of computer networks and types of computer networks
