Classification of computer network is divided into:A. Based
on geographical, computer networks are divided into a local area
network or Local Area Network (LAN), metropolitan area networks or
Metropolitan Area Network (MAN) and wide area network or wide area
network (WAN). Local area network]] is a private network inside a building or place that measures up to some 1-10 kilometers. LAN
is often used to connect personal computers and work stations
(workstation) in a corporate office or factories in order to use shared
resources (eg printers (printers) and exchange information. While the
metropolitan area network is a LAN network expansion that includes a
city ample,
consisting of dozens of buildings within 10-50 miles. cable
transmission used is a fiber optic cable (Coaxial Cable) wide area
network is a network of intercity, inter-provincial, inter-state, and
even between continents. distance can cover the whole world, for
example, a network that connects all the banks in Indonesia, or the
network that connects all Indonesian Representative Office in the world.
[8] is the main transmission medium of communication via satellite, but
many rely on fiber-optic connections between countries. [2. By
function, is divided into client-server network (Client-server) and End
to end Network (Peer-to-peer). [8] the client-server networks on a
single computer ddasaranya prepared a waiter (server) from another
computer as
a client (client). [8] All resources service request from a client
computer must be passed to the computer waiter, waiter computer that
will manage the service. [8] If the communication is very busy service
requests can even put more than one computer into a waiter, so there
is a division of tasks, such as file-server, print-server, database
server and so on. [8] Of course waiter computer configuration is usually
more than the client computer's configuration in terms of memory
capacity, hard disk space {disk), and the speed prosessornya. [ 8]
While the network end to end is indicated by the computers to support
each other, so each computer can request the use of shared resources
from other computers, so too must be ready to serve requests from other
computers. [8] The network model is usually only applied to the amount computer
that is not too much, maximum 25, because the communication would be
complicated and bogged down when the computer too much. [8]3. Based on network topology, network computers can be distinguished [3]:A. Bus topology2. Star topology3. Ring topology4. Mesh topology5. Tree topology6. Linear topology4. Based on the distribution of sources of information / dataA. Centralized networkThis
network consists of the client computer and the waiter where the client
computer that serves as an intermediary to access sources of
information / data from one computer waiter. [9]2. Distributed networkIs
a combination of several centralized network so that there are several
interconnected computer waiter with clients to form a specific network
system. [9]5. Based on data transmission mediaA. Wired Network (Wired Network)
