Kinds of Network.

ursuant to wide scope of working area geographically, computer network can be differentiated into some kinds of among others as follows.

1.LAN ( Local Area Network)
LAN that is a[n network system where each;every computer or hardware and software used so that earning is communicating each other in certain [job/activity] area by using [is] same program and data, also have speed of[is transfer of quicker data. LAN have maximal reach 100 metre.LAN formed caused by supporter component that is cable, And network card RJ45.

Amenity use LAN

• Data Sharing that is usage of resource with, printer case, modem, facsimile, and others

• Program Sharing that is accumulator with data bases and program

• Internet Sharing or intranet that is usage of broader network computer, either in office, international world and building

• quicker Data information

• Data distribution Prose

Type technological of LAN

• its Reach 100 speed metre Ethernet 100 / 10 Mbps applying of young yan.

• technological Lino 300 14 mbps metre Power of This LAN can use power cable which have there is. have been equiped by enkripsi 56 DES beet, and his excess of this is network technology very cheap.

• Wi-Fi ( 802.11b) reach from this technology reach 30 metre , and speed if when using this network technology 11/ 5.5 Mbps.

• Wi-Fi5(802.11A) reach from technological usage of this network only 15-20 metre, its speed 54 / 22 mbps. Technological of this network consist of 8 canal, while bandwidth which in earning very big.

• Reach Bluetooth if/when using this network technology only 9-20 metre, its of lower nya even also compared to other network technology only 1 Mbps / 300 Kbps, technological of this network integrated at PDA or ponsel.

Difference of Network LAN have cable to with LAN nirkabel network
conventional Network LAN with LAN nircabel network basically is same, just only is of connection method and component or peripheral in its of different nya.
Elementary difference which is very between LAN konversional network with LAN nirkabel network that is at usage of extension and cable in LAN itself development.
Excess use LAN nirkabel network very conducive access to workstation which do not have Ethernet card and very easy its development of using cable. Difference apart its reach for the network of LAN konversional as far as 50 metre, while for the network of area niekabel or reach energy between workstation by using relative point access farther

2. WAN (Wide Area Network)
WAN that is network technique having intercontinental activity area, by passing geographical boundary of public And property state.

3. MAN (Metropolitan Area Network)
MAN that is network having area work office region one town, building, factory, campus, and head office in its reach area. There by, MAN have geographical reach broadly between 10 kilometre up to 50 kilometre.

4 . INTERNET (Interconnection Networking)
Internet that is computer network globally able to be accessed to whole world, and can yield all infomasi.
5 WIRELES (Tanpa Kabel)
Wrireles that is network without cable using radio technology ( frekuensi) or recognized with WLAN (WIRELESS network area local term) or referred as also with Wifi term
