There are five types of terminal and keyboard is a common terminal and the most popular.
- Keyboard input terminal is a terminal that is very popular among computer users. Users can use the keyboard mengentri data, provide specific instructions to publish reports and so on.
- Telephone Terminal keys: the computer can also be equipped with audio response. Can send messages that can be heard by the user on the telephone keypad. Key presses are used to transmit data and instructions into the computer.
- Point of sale terminal (point of sale) We can also see how the optical character reader used in the supermarket. This terminal provides a way of entering transaction data into the database at the time penjuala (point of sale). For this reason the terminal is called the terminal point of sale (POS)
- Terminal Data Collector. A special type of terminal is designed for use by factory workers. Device known as a data collection terminal (data collection terminal) used to collect data, identifies employee attendance and job performance. OCR tool used to read characters and document that accompanies the work that goes on in the factory.
- Special terminal is a terminal that is designed specifically for certain keperlua such as cash registers equipped with special buttons. One button for one type of seller
2.NIC (Network Interface Card)
Network cards installed on each computer that will be connected to a computer network nic. Many types and brands of network cards are available in the market, but some basic things you need to know which type of network card is ISA or PCI card with a speed of 10 or 10/100 Mbps, must be tailored to the type of Ethernet switching HUB or to be used, the type of protocol and cable types it supports as it also ruled out quality products. New kind of computer is not equipped with even ISA slots onboard Network Interface is generally a system that is already available on the mainboard so no need to be installed LAN Card
In accordance with the level of demand for computer networks, many new types of computer mainboard equipped with a network card on board. Good quality, but the author believes is better to use a separate network card. One advantage is that it can choose a specific brand and easily replaced if damage occurs.

3.Hub or Concentrator
Hub is a network device that consists of many ports for connecting a Node or point-and hup-switch.jpgsehingga form networks that are connected in a star topology. If the number of ports available is not sufficient to connect all computers to be connected into a single network can be used several hubs connected in up-link.

If the number of ports available is not sufficient to connect all computers to be connected into a single network can be used several hubs connected in up-link.
Ports are available usually until 8, 16, 24 or more to suit your needs. For speed, you can use a HUB or Switch 10 10/100. We recommend using 10/100 because it can be used for network speed up to 10 or 100. There Hub which supports the use of coaxial cable and UTP support their BUS topology that supports the STAR topology. But the latest type tend to only provide support for the use of UTP cabling.
4.Konektor UTP (RJ-45)
RJ45. UTP cable required to connect the RJ-45 jack or similar that looks similar to a phone jack cable but has more holes in the cable. The connector is mounted at both ends of the cable with pliers special equipment UTP. But if you can not install it, you can ask at the time of purchase as well as installation of UTP cables

6.Bridge
Bridge is used to link between networks that have the same protocol. The end result is a single logical network. Bridge can also use the network that have different physical media. Tissue samples using a fiber network using obtik with coacial.
Bridge study destination address and directs traffic to pass through to the destination. Also used to insulate the network. If network traffic is slowed by the presence of full then the network can be divided into two smaller unit.

7.Switch
Bridge is a development of the concept. There are two basic architectures used on the switch, the cut-through and store and forward. Cut-through switches have advantages in terms of speed because when a packet comes, the switch is only concerned with the destination address before being forwarded to tijuannya segment, while the switch store and forward is the opposite. These switches receive and inspect the entire contents of the package before it passes into the goal and to check the package needs the time, but this process allows the switch aware of the damage and prevent the data packets so as not to disrupt the network.
By Swith there are several advantages for all segments of the network has a bandwidth of 10 Mbps full. Such undivided share in the use of the Hub network.

9.Multiplexer
When a terminal must share a single channel at the same time, the multiplexer can be added at each end. Multiplexer is a device that allows sending and receiving of multiple messages simultaneously. The addition of such an impact alter multiplexer one lane road becomes a freeway with multiple lanes. Setting port numbers and protocols that send data at the correct software module within the host.

10.Front-end Processor
Front-end Processor handles the computer network traffic in and out of the host computer. Both of these computers can be of any type, but the general configuration consists of a special kind of a mini computer that serves as a front-end processor and a host mainframe.
Front-end Processor serves as input from the host unit to collect the messages that come in and prepare the data for the host. Front-end processor also functions as a unit with the output from the host to receive messages for transmission to the terminal.
Although the transmission speed between the channel and the front end processor is relatively slow (in most cases the bits are transmitted serially) tarnsmisi speed front-end processor with a host can take place quickly (a few bits are transmitted in parallel).
Most of the front-end processor do message switching by setting the route (routing) messages from one terminal to another without involving the host. If for some reason the receiver can not receive a message (perhaps Whereas, used or damaged) front-end processor can store the message in the secondary storage and send it later. This capability is called store and forward (store and forward).

11. Host
Host data processing work for the network. Incoming messages are handled the same way with the data received from the unit in any type of unit. After processing the message can be transmitted back to the front-end processor for routing.

12.Router
Routers do not have the ability to learn, but can specify the path (flow) data between the two networks are most efficient at. Routers operate at the Network layer (OSI layer three.). Routers do not care about the topology and the level used by the network acces. Because it operates at the network layer. He is not hindered by the media or communications protocol. Bridge can know the final destination of data packets, Router only knows where the next router is placed. It can be used to connect networks that use the same high level protocol.
If a data packet arrives at the router, it determines the best route for packets to conduct checks on the router table. He only saw only see the packets sent to it by the previous router.

15.Modem
The only time is when the modem is not required to use the telephone as a terminal. All other computer network channels requires a modem at each end. Modem is designed to operate at a certain speed is usually 300, 1200, 2400, 4800 or 96 000 bits per second and so on modem speed determines the speed of data transmission.
ADSL is a type of modem to use high speed internet accses. Generally ADSL modem is an integration of the modem, firewall and ethernet switches and routers, and possibly also with transiever. ADSL modem working on a different frequency to the frequency used in conversation, so telephon telephon lines can be used to percapapan conjunction with the use of data transmission via the ADSL modem.

16.Radio
Data transmission is also done through radio frequency as the banking network digunalan, Travel, cafe. This equipment is still dominated by public service providers (providers) such as the PT Lintas Artha, Indosat, Telkomsel. Fren. For smaller scope for making available werless local network without wires. For example, the ADSL modem router comes with werless can be used for local networks in the room. Only werles ability can not be disturbed by the partition or partitions mainly concrete. so it is not effectively used for local network of an enterprise in which the client computer in confined spaces scattered.
