The Advanced Research Projects Agency (ARPA) designed Advanced ResearchProjects Agency Network (ARPANET   ) for the United States Department of Defense. It was thefirst computer network in the world in late 1960s and early 1970s. [1] I Network classification The following list presents categories used for classifying networks. 1.Connection method  Computer networks can also be classified according to the hardware and software technologythat is used to interconnect the individual devices in the network, such asOptical fiber ,Ethernet, Wireless LAN,HomePNA,Power line communicationor  G.hn. Ethernet uses physical wiring to connect devices. Frequently deployed devices include hubs, switches, bridges and/or routers.Wireless LAN technology is designed to connect devices without wiring. These devices useradio wavesor infraredsignals as a transmission medium. ITU-T G.hntechnology uses existing home wiring (coaxial cable, phone lines and  power lines   )to create a high-speed (up to 1 Gigabit/s) local area network. Wired Technologies Twisted-Pair Wire - This is the most widely used medium for telecommunication. Twisted-pair wires are ordinary telephone wires which consist of two insulated copper wires twisted into pairsand are used for both voice and data transmission. The use of two wires twisted together helps toreduce crosstalk and electromagnetic induction. The transmission speed range from 2 million bits per second to 100 million bits per second. Coaxial Cable – These cables are widely used for cable television systems, office buildings, andother worksites for local area networks. The cables consist of copper or aluminum wire wrappedwith insulating layer typically of a flexible material with a high dielectric constant, all of whichare surrounded by a conductive layer. The layers of insulation help minimize interference anddistortion. Transmission speed range from 200 million to more than 500 million bits per second.  Fiber Optics – These cables consist of one or more thin filaments of glass fiber wrapped in a protective layer. It transmits light which can travel over long distance and higher bandwidths.Fiber-optic cables are not affected by electromagnetic radiation. Transmission speed could go up  to as high as trillions of bits per second. The speed of fiber optics is hundreds of times faster thancoaxial cables and thousands of times faster than twisted-pair wire. Wireless Technologies Terrestrial Microwave – Terrestrial microwaves use Earth-based transmitter and receiver. Theequipment look similar to satellite dishes. Terrestrial microwaves use low-gigahertz range, whichlimits all communications to line-of-sight. Path between relay stations spaced approx. 30 milesapart. Microwave antennas are usually placed on top of buildings, towers, hills, and mountain peaks. Communications Satellites – The satellites use microwave radio as their telecommunicationsmedium which are not deflected by the Earth's atmosphere. The satellites are stationed in space,typically 22,000 miles above the equator. These Earth-orbiting systems are capable of receivingand relaying voice, data, and TV signals. Cellular and PCS Systems – Use several radio communications technologies. The systems aredivided to different geographic area. Each area has low-power transmitter or radio relay antennadevice to relay calls from one area to the next area. Wireless LANs – Wireless local area network use a high-frequency radio technology similar todigital cellular and a low-frequency radio technology. Wireless LANS use spread spectrumtechnology to enable communication between multiple devices in a limited area. Example of open-standard wireless radio-wave technology is IEEE 802.11b.  Bluetooth – A short range wireless technology. Operate at approx. 1Mbps with range from 10 to100 meters. Bluetooth is an open wireless protocol for data exchange over short distances. The Wireless Web – The wireless web refers to the use of the World Wide Web throughequipments like cellular phones, pagers, PDAs, and other portable communications devices. Thewireless web service offers anytime/anywhere connection. 2. Scale  Networks are often classified as Local Area Network (LAN), Wide Area Network (WAN), Metropolitan Area Network (MAN), Personal Area Network (PAN),Virtual Private Network  (VPN), Campus Area Network (CAN), Storage Area Network (SAN), etc. depending on their  scale, scope and purpose. Usage, trust levels and access rights often differ between these types of network - for example, LANs tend to be designed for internal use by an organization's internalsystems and employees in individual physical locations (such as a building), while WANs mayconnect physically separate parts of an organization to each other and may include connectionsto third parties.
