Computer
Networking in general there are five kinds, namely LAN (Local Area Network),
MAN (Metropolitan Area Network), WAN (Wide Area Network), Internet, and
Wireless (cordless). Actually, the concept of the type of computer network,
which is to connect the various network devices to communicate and share
resources. Only difference is the location of the geological his (include area
and area network) and the technology used (such as the use of different types
of cable, IP Addressing its corresponding class, and security systems
(security) is different). So, I will explain about the 5 Types Computer
Networks according to sources I get, both from the teachers of SMK N 3
Singaraja and softcopy or hadrcopy I have.
* LAN (Local Area Network)
Local Area Network or LAN, is a type of computer network which includes a local area. By using a variety of network devices is quite simple and popular, such as using UTP (Unshielded Twisted-Pair), Hubs, Switches, Routers, and other sebagainya.Contoh of the LAN network as the computers that are connected to the school, in the company, figuring , and between neighboring houses that still covers an area LAN.
The advantage of using LAN Computer Network Type as more economical in operating expenses, more efficient in the use of cables, data transfer between nodes and computers seem to be more rapid because it covers a narrow area or local, and does not require operators to create a LAN network.
The disadvantage of using LAN Network Type is narrower network coverage so as to communicate outside the network becomes more difficult and area coverage data transfer is not so wide.
* MAN (Metropolitan Area Network)

Metropolitan Area Network or MAN, is a type of computer network wider and more sophisticated than Type Computer Network LAN. Known as Metropolitan Area Network MAN Computer Network Type is commonly used to connect a computer network from a city to another. To be able to make a MAN network, usually necessary to telecommunications operators to interconnect computer networks. Examples such as the Ministry of Education network between cities or regions as well as modern malls networks interconnected between cities.
The advantage of this type include Computer Network MAN is a broader network coverage so as to communicate becomes more efficient, in terms of ease of doing business, as well as in the network security better.
Loss of Computer Network Type MAN as more use of operational costs, could be targeted by the operation of the Cracker for personal benefit, and for tissue repair MAN it takes a long time.
* WAN (Wide Area Network)
Wide Area Network or WAN, is a type of computer network wider and more sophisticated than the type of computer network LAN and MAN. JaringanWAN technology is used to connect a network to another state or from one continent to another. WAN network can consist of different types of LAN and WAN computer network for wide area coverage of Computer Network WAN type. Networks WAN, typically using fiber optic cable, and implanting them in the ground or under the sea passing lane.
Advantages Types Computer Networking WAN as a wider network coverage of Computer Network Types LAN and MAN, the exchange of information becomes more covert and targeted due to communication from one country to another requires more security, and also easier to develop and ease in terms of business.
Loss of type Network WAN as operational costs needed to be more, are particularly vulnerable to the dangers of theft of important data, care for WAN networks become more severe.
* Internet
The Internet is a global computer network or the global. Because the Internet is a network-connected computer networks worldwide, so the communication and transfer of data or files is easier. Internet can be said to be a mix of different types and their Computer Network Topology and Network Type interconnected with each other.
Advantages of Internet Network Types include communication and sharing of resources from one network to another easier, dissemination of knowledge becomes more rapid, delivering information faster and easier, and into the fields to earn
Loss of Internet Network Types include cyber crime or cyber criminals become widespread, pornography is becoming increasingly widespread, the transaction illegal goods such as drugs became rampant, and can also cause a scandal due to incorrect information delivery.
* Wireless (Without Cable)
Wireless is a type of computer network that uses the medium of data transmission without cables. The media used such as radio waves, infrared, bluetooth, and a microwave. Wireless can work into a LAN, MAN, and WAN. Wireless intended for high mobility.
Advantage Wireless Network Type as convenience to connect to the network without being restricted by cables, more towards users who need greater mobility, and do not actually need a network cable.
Wireless Network Type losses such as the transmission of data to the users is slower than using a wired network, requiring tight security because people who are outside the network can break into a wireless network.
* LAN (Local Area Network)

By using a variety of network devices is quite simple and popular, such as using UTP (Unshielded Twisted-Pair), Hubs, Switches, Routers, and other sebagainya.Contoh of the LAN network as the computers that are connected to the school, in the company, figuring , and between neighboring houses that still covers an area LAN.
