Network: the network (the network) is a collection of two or more computer systems are connected.
Type of Network Computers based on the geographical coverage:
1. Local Area Network (LAN)
Local Area Network (LAN), a network of private property in a building
or the size of the campus until several kilometers. LANs are often used
to connect personal computers and workstations in the office
a company or factory to put together the resources (resouce,
for example, printers) and exchange information.
2. Metropolitan Area Network (MAN)
Metropolitan Area Network (MAN), basically, is a LAN version of the
the size larger and usually use the same technology with a LAN.
MAN could include offices of companies that are also situated near or
a city and can be used for personal purposes (private) or the public.
MAN able to support voice and data, can even be associated with the network
cable television.
3. Wide Area Network (WAN)
Wide Area Network (WAN), the outreach includes a broad geographic area, often covering a country even continents. WAN consists of a collection of machine engine
which aims to run programs (applications) user.
Based on the role and relationship of each computer in the process of data:
- Client-Server
In this network, there are 1 or more computer servers and client computers. Each computer can become a client and server
-Peer-to-peer
In this network there is no client computer and server computer because the computer can do all the delivery and reception of information so that all client computers to function as well as server.Ada that act as a server as a client.
Based on the data transmission media:
- (wired Network)
In this network, to connect one computer to another computer needed a cable network operator. Cable network functioning in sending information in the form of electrical signals between a computer network.
- Wireless Network (Wireless Network)
Is a network with a medium electromagnetic waves. In this network is not required to connect a cable between the computer because it uses electromagnetic waves that will send the signal information between the computer network.
Hardware Components
-Server
Computers that act as server.menyediakan files, printers and other services for clien
-Workstation
Is part of the existing network. In fact, the workstations used by consumers directly
-Network Interface Card (NIC)
NIC, or network adapter is a computer hardware that is absolutely necessary if we want to use up computer network connecting the cable media. NIC to the server operating system to pengkabelan network. Based on the type of slot on the motherboard are divided into two types:
* Type ISA slot (slot black / brown, long more)
* Type PCI slots (slot white, short more)
-Switch/Hub (Concentrator / Repeater)
a tool to make the network transparent bridging (communicator segementasi many network based on a forwarding address with the MAC).
Switch network can be used as a computer or router on one area, limited switch is also working on the data link layer, how the switch works almost the same as the bridge, but the switch has a number of ports that are often called multi-port bridge.
-Bridge, Router and Gateway
Bridge connecting the two work with the network to transfer data between the network. For example, the bridge can connect the cable segments from the Token Ring architecture with Ethernet architecture, or connect two Ethernet segments into one. Bridge is able to reduce traffic by only sending data that really diniatkan computer to the destination. Bridge smart (intelligent bridge) can do better with a filter or just to send packages to certain destinations.
-Uninterrutible-Power Supply (UPS)
UPS is a very important tool for companies that use computers to produktifitasnya and do not want to lose data or working time employees. In every situation that can, via UPS is a profitable investment for each workstation, the hub, and the server on the network.
