2. Motherboard - A motherboard is the central printed circuit board (PCB) in many modern computers and holds many of the crucial components of the system, while providing connectors for other peripherals.

4. Network - A network is a collection of terminals, computers, servers, and components which allows for the easy flow of data and use of resources between one another.
5. Signal - In electronics, a signal is an electric current or electromagnetic field used to convey data from one place to another. The simplest form of signal is a direct current (DC) that is switched on and off; this is the principle by which the early telegraph worked. More complex signals consist of an alternating-current (AC) or electromagnetic carrier that contains one or more data streams.
6. Local Area Network - a local computer network for communication between computers; especially a network connecting computers and word processors and other electronic office equipment to create a communication system between offices
7. Wide Area Network - A network that includes computers spread across a large geographical distance, usually involving several cities, states or countries. Communications connections in a WAN are typically done over modems, T1 lines, or satellite hookups.
8. Network Server - LANs use a powerful microcomputer with a large disk capacity as a file server or network server. The server handles resource sharing and telecommunications.
9. Work station - A workstation is a high-end microcomputer designed for technical or scientific applications. Intended primarily to be used by one person at a time, they are commonly connected to a local area network and run multi-user operating systems.
10. Host - In computer networking, a network host, Internet host, host, or Internet node is a computer connected to the Internet - or more generically - to any type of data network. A network host can host information resources as well as application software for providing network services.
11. Network TopologiesNetwork topology is defined as the interconnection of the various elements (links, nodes, etc.) of a computer network.[1][2] Network Topologies can be physical or logical. Physical Topology means the physical design of a network including the devices, location and cable installation. Logical topology refers to the fact that how data actually transfers in a network as opposed to its physical design.<br />Physical topologies<br />The mapping of the nodes of a network and the physical connections between them – i.e., the layout of wiring, cables, the locations of nodes, and the interconnections between the nodes and the cabling or wiring system<br />Signal topology<br />The mapping of the actual connections between the nodes of a network, as evidenced by the path that the signals take when propagating between the nodes.<br />Logical topology<br />The logical topology, in contrast to the quot;
physicalquot;
, is the way that the signals act on the network media, or the way that the data passes through the network from one device to the next without regard to the physical interconnection of the devices. A network's logical topology is not necessarily the same as its physical topology. For example, twisted pair Ethernet is a logical bus topology in a physical star topology layout. While IBM's Token Ring is a logical ring topology, it is physically set up in a star topology.<br />
