Brandon Douglas Bradshaw studied computer science and information systems for many years and it became his passion. In her studies, she discovered some very important facts founder. Computer networks can be defined as an engineering discipline to the interaction between the devices of the computer systems and computers. Routing protocols, networks, routers and network systems in all types of Internet services have appointed their coordinates defined in RFCs (Request For Comments). Computer networks is also available as a discipline of computer science, telecommunications, computer and information technology. It includes theoretical and practical applications of engineering and scientific disciplines. There are three types of computer networks: 1 Internet 2 Intranet and 3 Extranet.
Generally, a computer-network rates from various devices and computers that are connected with each other with function for sending or receiving data. Here are the different types of computer networks that is Brandon Douglas Bradshaw with known

* MAN (Metropolitan Area Network): This is the average size of the network with a city or state.
* WAN (Wide Area Network): This is a commercial network and the geographical area to grow.
* WLAN & WWAN (wireless LAN and MAN) networks are the equivalent of the WAN and LAN in a wireless form.
There are all types of computer networks that are interconnected to allow communication takes place between different media such as cable copper wire, fiber optic, coaxial cable, microwave systems, power lines and various wireless technologies. Computing devices for set-ups, up to a few meters or unlimited distances are used, depending on the area.
There are many organizations such as insurance companies, railways, hospitals, banks, etc. that meets the needs of real-time processing of the huge number of transactions that interact through many computer systems and communicate with each other via the same network. Thus, the process for the installation of a computer as a whole is very important and sensitive.
