General terms in the Network Computer

Network: the network (the network) is a collection of two or more computer systems are connected. There are many types of computer networks:
a. local-area network (LAN) computer that is connected to the place near the gografis (for instance a building).
b. wide-area network (WAN) that connect the computer on which far apart and connected by phone line or radio waves. besides, the computer network can also be grouped based on the following criteria:
a. topology: keterhubungan between the computer system. There are various topology such as bus, star, and ring.
b. protocols: the protocol defines a set of rules and signals used by computers on the network to communicate. LAN protocol is the most popular Ethernet. LAN protocol that is widely used IBM token-ring network.
c. architecture: the network can be classified into the architecture of peer-to-peer or client / server.

NIC: NIC (network interface card) Expansion board, which is used so that the computer can be connected to the network. Most NICs are designed for the network, protocol, and certain media. NIC called with a LAN card (Local Area Network Card).

Backbone: background is the channel or high-speed connection that the main track in a network.

Bandwidth: Bandwidth showed the capacity to bring in information. This term can be used in many ways: phone, cable network, bus, the radio frequency signal, and the monitor. Most appropriate, bandwidth is measured by lap perdetik (cycles per second), or cindy (Hz), the difference between the lowest and highest frequency that can ditransmisikan. But also often used size bits per second (bps).

Bridge: Bridge is a device that continue to traffic between network segments based on the information in the data link layer. This segment has a network layer address the same. Each network should only have a main bridge.

DNS: DNS (domain name system) is a system that translates Internet domain, such as www.microsoft.com into Internet addresses, namely a series of numbers that look like 101.232.12.5. The term associated with the DNS naming convention for the host on the Internet and how recently the names of these.

Ethernet: Ethernet is a LAN protocol developed by Xerox Corporation who cooperated with DEC and Intel in 1976. Ethernet using the bus or star topology and medukung transfer data up to 10 Mbps. Ethernet version of the new called 100Base-T (or Fast Ethernet), supports data transfer up to 100 Mbps, and the newest version, Gigabit Ethernet, supports data transfer up to 1 Gigabit per second or 1000 Mbps.

Fast Ethernet: Fast Ethernet Ethernet as usual, but with the speed of data transfer faster, with up to 100 Mbps. Ethernet is also called 100BaseT.

Gateway: The term refers to the gateway hardware or software to bridge the two networks or applications that are not compatible, so that data can be transferred between computers vary. One example is the use of the email gateway, so that the exchange of email can be done in a different system.

GPS: Global Positioning System (GPS) navigation system is using 24 satellites MEO (medium earth orbit or a middle earth orbit) the earth and the recipients of the earth. Mengorbit on satellite altitude around 12,000 miles above the earth and able to circumnavigate the earth twice in 24 hours. GPS satellites send a continuous radio signal that contains a digital satellite location data and time related to the recipient. GPS satellites equipped with atomic clock with the accuracy of one per one million seconds. Based on this information, the station recipient know how long that is used to send a signal to the receiver in the earth. The longer the time used for up to the recipient, the more distant position from the satellite receiver station. The position of the satellite, the recipient knows that the satellite is located in a certain position on the surface of the ball imaginer based on the satellite. By using three satellites, GPS can calculate the latitude and longitude recipient based perpotongan third ball imaginer. By using four satellites, can also be specified height. GPS is developed and operated by the United States Department of Defense. GPS, originally known as the NAVSTAR (Navigation System with Timing and Ranging). Before the need for a broader, GPS is used to provide navigation capability over time and in all weather for military land, sea and air forces. Besides for navigation and geographic positioning, GPS can also be used on them for mapping, forestry, mineral exploration, wildlife habitat management, and monitoring the movement of the population.

Host: Host computer system that is accessed by users that work in remote locations. Usually, the term is used if there are two computer systems connected to the modem and phone lines. The system contains data that is called the host, is being used for any mengases called distance from the remote terminal. The term is also used to host his computer connected to the network TCP / IP, including the Internet. Every host has a unique IP address. In addition, the term also refers to host the provision of infrastructure services on the computer. For example, many companies that host Web servers, which means that the company is providing the hardware, software and communication channels that are required by the server, but the content server (data) is controlled by the other party.

ISP (Internet Service Provider): ISP (Internet service provider) is the Internet service provider. Most ISPs have a network server (mail, news, web), router, modem connection that is connected with the "backbone" of the Internet and high-speed permanent. ISP customers can get Internet connection with a modem and telephone. To access the Internet ISP customers must dial to make the network by pressing the phone number belong to a particular ISP.

Internet: the Internet is a global network that connects millions of computers. Since 1999 the Internet has 200 million users worldwide, and this number increased rapidly. More than 100 countries connected to the Internet to exchange data, news and other information. Every computer connected to the Internet called the host.

ISDN: ISDN (Integrated Services Digital Network) is an international communications standard for sending voice, video and data through a digital phone line or a regular phone wires. ISDN has a data transfer speed of 64 Kbps. Most of the ISDN lines offered by telephone companies, which allows two channels, called the canal B (B channels). One line can be used for voice and other data for the other and both have speed transfer of 128 Kbps. Early versions of ISDN use baseband transmission. Another version of ISDN, the B-ISDN, uses broadband transmission and can support data transmission with a speed of 1.5 Mbps.

Protocol (the protocol): English, or the procedures used by the relationship that a computer system with other systems that can be mutually between both berhububngan. To be able to communicate. Both systems must use the same protocol.

PPP (Point to Point Protocol): Protocol TCP / IP, which allows the relationship between host and network with the router with a router or can also be used for the serial relationship between 2 system.

Repeater: A device installed in certain points in the network to update signals in order to achieve the return transmisikan strength and shape of the original, in order to extend the distance that can be located. This is in need because the signals have perlemahan and change shape during transmission.

Router: A device that functions as a link to an internetworking LAN / WAN and manage the distribution of traffic data in it.

Routing: The process of determining a path in life to send data to a particular purpose.

RJ-45: RJ-45 (Registered Jack-45) is eight cable connectors that are used to connect a computer to a local-area network (LAN), especially Ethernets. RJ-45 connectors similar to the RJ-11 connectors used in the telephone connection, but larger.

Server: A unit that works to save information and to manage a network server komputer.komputer will serve all of the client or worstation connected to the network.

TCP / IP: TCP / IP Transmission Control Protocol are two protocols developed by the U.S. military, which allows computers on the network can contact each other. IP packet used to move data antarsimpul. TCP dugunakan to verify the delivery of the client to the server. TCP / IP is the basis of the Internet and can be found on all modern operating systems, such as Unix and Windows.

Topology: In the computer network topology is a form of the keterhubungan between computer systems. There are various topology such as bus, star, ring.

UTP: UTP (Unshielded Twisted Pair) is the type of cable that consists of two wires that my not gyrate. UTP cable is used in many local-area networks (LANs) and a phone connection because cheaper. UTP cable is not as good as cable and fiber optic koaksial in supplying banwidth and resilience against interference.

VLAN: VLAN (virtual local-area network) is a network computer that is connected using cable as the same, although perhaps physically located on the LAN to another. VLAN configured by software and not hardware, which makes very fleksible.
One of the benefits of the VLAN if a computer is physically moved to another location, the computer is still on the same VLAN without re-configuration of hardware.

VPN: VPN (virtual private network) is a private internet connection in a safe and encrypted to ensure that only users who are eligible and can access the data trasfer can not be disturbed.

VSAT: VSAT (Very Small Aperture Terminal) earth station used in satellite communications signal data, voice and video, except the television. VSAT consists of two parts: a transceiver that is placed by open so it can directly receive signals from satellites and a tool placed in the room to connect the transceiver and a tool of communication end-user (end user), such as a PC.
Transceiver to receive and send signals to the satellite transponder space outside. Send and receive satellite signals from the ground station computer that functions as the hub system. Each user is connected with each other stasiunhub pass through satellites, forming a star topology. the hub to control all operating on the network. All transmission for communication between users must pass through the stasiunhub forward to kepengguna VSAT satellite and the other. VSAT can send data up to the speed of 56 Kbps.

WAN: WAN wide area network is the computer that is connected to the place that far apart and the relationship with the phone line or radio waves. See also LAN and network.

Wi-Fi: Wi-Fi Wireless Fidelity is the official trade name for IEEE 802.11b, which is made by the Aliance Wireless Ethernet Compatibility (WECA). The term Wi-Fi 802.11b replace terms such as IEEE 802.3 Ethernet replace. Products certified by WECA as Wi-Fi can operate together, although made by different companies.

Workstation: In the network computer, workstation computer that is connected with a local-area network (LAN).
The term is also used as a workstation for his computer used for engineering applications (CAD / CAM), desktop publishing, software development, and other applications that require high computing and graphics capability that is high enough.
Workstation usually consists of a large graphic display with a high revolution, at least 64 MB of RAM, network support built-in, and the graphical user interface.
Most of the workstations also have tools such as storage disk drives, but a special type of workstation, called diskless workstation, does not have a disk drive. Operating system used for the UNIX workstation and Windows NT. Like the PC, most of the computer workstation is a single user, however, the workstations are basically linked with a local area network, although it can also sebgian system that stand alone stand alone.

100BaseT: 100BaseT is another name that has a fast Ethernet transmission speeds up to 100 Mbps. This type of 100BaseT more expensive than 10BaseT and more rarely used in local area network (LAN).

10Base2: 10Base2 is a type of standard Ethernet (IEEE802.3) to a local area network (LAN). Standard 10 Base-2 (also called the Thinnet) using koasial 50 ohm cable (RG-58A / U) with a maximum length of 185 meter.kabel is smaller and more than flesibel used for the standard 10 Base 5. System 10 Base-2 operates at 10 Mbps and use the method tranmisi baseband.

10 Base5: 10 Base-5 adalqh standard Ethernet beginning to use the cable koasial. 10 Base5 name is based on the fact that the maximum data transfer speed is 10 Mbps. Baseband transmission using, and the maximum length of cable is 500 meters. 10 Base5 also called Thick Wire Net or thick.



10BaseT: 10BaseT Ethernet is the type most common. Name shows that the maximum transmission speed is 10Mbps. 10BaseT using copper cable and a standard card to connect computers on a local area network (LAN)
