Network: the network (network) is a collection of two or more computer systems connected. There are many types of computer networks:
a. Local-Area Network (LAN) connected computers are in place adjacent to geografis (eg a building).
b. Wide-Area Network (WAN) that connects computers located in a remote place and connected by telephone lines or radio waves. in addition, a computer network can also be classified based on the following criteria:
Topology: connection settings between computer systems. There are a variety of topologies such as bus, star, and ring.
Protocol: the protocol defines a bunch of rules and signals used by computers on the network to communicate. The most popular LAN protocol is Ethernet. Other LAN protocol that is widely used is the 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) is an expansion board that is used so that computers can be connected to the network. Most NICs are designed for networks, protocols, and certain media. Commonly called the NIC LAN card (Local Area Network Card).
Backbone: Backbone is a channel or high-speed connection to the main path in a network. Bandwidth: Bandwidth to show the capacity to carry information. This term can be used in many ways: phone, cable networks, buses, radio frequency signals, and monitors. Most appropriate, bandwidth is measured in rounds per second (cycles per second), or hertz (Hz), ie the difference between the lowest and highest frequency that can be transmitted. But it is also frequently used measure of bits per second (bps).
Bridge: Bridge is a device that forwards traffic between network segments based on the data link layer information. This segment has the same network layer address. Every network should only have a major bridge.
DNS: DNS (domain name system) is a system that translates Internet domain, such as www.microsoft.com into Internet addresses, a series of numbers that look like 101.232.12.5. The term control related to the conventions for naming hosts on the Internet and how to handling these names.
Ethernet: Ethernet is a LAN protocol developed by Xerox Corporation in cooperation with DEC and Intel in 1976. Ethernet uses a bus or star topology and call for support for data transfer up to 10 Mbps. A newer version of Ethernet, 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 as usual, but with a speed faster data transfer, up to 100 mbps. It also called 100BaseT Ethernet.
Gateway: The term gateway refers to hardware or software that bridges the two applications or networks that are not compatible, so the data can be transferred between different computers. One example of the use of an email gateway, so that email exchanges can be performed on different systems.
GPS: GPS (Global Positioning System) navigation system uses satellite 24 MEO (medium earth orbit or middle earth orbit) around the earth and the recipients of the earth. Satellites orbiting at an altitude of approximately 12,000 miles above the earth and is able to circle the earth twice in 24 hours. GPS satellites continuously transmit digital radio signals containing satellite location data and time corresponding to the recipient. GPS satellites equipped with atomic clocks with a precision of one per one million seconds. Based on this information, the receiving station knows how long it will be used to send signals to the receiver on earth. The longer the time spent to get to the recipient, the more distant position from the satellite receiving station. by knowing the position of satellites, the receiver knows that the satellite is located at a certain position on the surface of the imaginary sphere centered on the satellite. By using three satellites, GPS can calculate the latitude and longitude based on the intersection of the third recipient of the imaginary sphere. By using four satellites, it can also be determined height. GPS was developed and operated by the U.S. Defense Department. GPS, originally known as NAVSTAR (Navigation System with Timing and ranging). Prior to the broader purposes, GPS is used to provide navigation capabilities at all times and in all weather for military land, sea and air forces. In addition to navigation and geographic positioning, GPS can also be used in between for mapping, forestry, mineral exploration, management of wild habitats, and migration control.
Host: Host is a computer system that is accessed by users who work in remote locations. Typically, this term is used if there are two computer systems connected by modems and telephone lines. The system contains data that is called the host, the system was used to assess from a distance is called the remote terminal. The term is also used to refer to a host computer connected to a TCP / IP, including the Internet. Each host has a unique IP address. In addition, the term also refers to the host computer services infrastructure. For example, many companies that host Web servers, which means that the company provides hardware, software, and communication channels required by the server, but the content server (data) is controlled by another party. ISP (Internet Service Provider): ISP (Internet service provider) is a provider of Internet services. Most ISPs have a network of servers (mail, news, Web), routers, modems are connected with the "backbone" of a permanent Internet and high speed. ISP customers can get an Internet connection with modem and telephone. To access the ISP's Internet subscribers have to dial into the network by pressing a certain number of ISPs.
Internet: The Internet is a global network connecting millions of computers. Since 1999 the Internet has had 200 million users worldwide, and this number is increasing rapidly. More than 100 countries connected to the Internet to exchange data, news, and other information. Every computer connected to the Internet is called the host.
ISDN: ISDN (Integrated Services Digital Network) is an international communications standard for sending voice, video and data over digital telephone lines or normal telephone wires. ISDN has a data transfer rate of 64 Kbps. Most ISDN lines offered by telephone companies which allows the two channels, called B channels (B channels). One line can be used for voice and another for the other and both have data transfer rates of 128 Kbps. Initial version of ISDN uses baseband transmission. Other versions of ISDN, the B-ISDN, uses broadband transmission and can support data transmission speed of 1.5 Mbps.
Protocol (protocol): Language or procedures used by a computer system with other systems so the two can be mutually berhububngan. To be able to communicate. Both systems must use the same protocol. PPP (Point To Point Protocol): Protocol TCP / IP that allows the relationship between the host and the network between the router with a router or can be used for the serial connection between two systems.
Repeater: A device installed at certain points in the network to update the signals transmitted in order to achieve the strength and shape of the original, in order to extend the distance that can be in use. This is needed because the signals have weakening and changes shape during transmission.
Router: A device that serves to connect a LAN to an internetworking / WAN and manage the distribution of data traffic in it. Routing: The process of determining a path in use to send data to a specific destination.
RJ-45: RJ-45 (Registered Jack-45) is an eight wire connector is typically used to connect computers to a local-area network (LAN), especially Ethernets. RJ-45 connector is similar to the RJ-11 connector used in telephone connections, but bigger.

UTP cable is not as good as coaxial cable and fiber optics in terms of providing banwidth and resistance to interference.
VLAN: VLAN (virtual local-area network) is a computer network as if connected using the same wire even though it may be physically located in another part of the LAN. VLANs are configured through software and not hardware, which makes it very fleksible.Salah one advantage of VLANs is that when a computer is physically moved to another location, the computer remains on the same VLAN without any hardware reconfiguration.
VPN: VPN (virtual private network) is a private Internet connections are secure and encrypted to ensure that only entitled users can access it and transfer the data that do not be disturbed.
VSAT: VSAT (Very Small Aperture Terminal) earth stations that are used in satellite communications of data signals, voice, and video, except for television broadcasting. VSAT consists of two parts: a transceiver that is placed in the open so it can directly receive signals from a satellite and a device that is placed in the room to connect the transceiver and the end user communication device (end user), such as PC.Transceiver receive and send signals to the transponder satellites in outer space. The satellite sends and receives signals from an earth station computer that serves as a hub system. Any users that are connected with stasiunhub through the satellite, forming a star topology. hub to control all operations on the network. All transmissions for communication between the user must pass stasiunhub to kepengguna VSAT satellite and others. VSAT can transmit data up to speeds of 56 Kbps.
