	Some type of computer network is comprised of different devices to share, transmit, and boost the signal, voice and data.[http://www.billigaabercrombiebutiken.com/ abercrombie och fitch kjolar] , Network devices or components are the physical parts attached to a network.[http://www.varmetiffany.com/ tiffany ring] , There is a large number of the network devices and are increasing daily.[http://www.ghdsalonstyler.com/ pink ghds] , The basic network products are: Individual Computers, Server, Hub, Switch, Bridges, Routers, Modems, Printers, DSL Modems & Routers, Gateways, Network Interface Cards, Cabling & Wireless entry way.[http://www.cheapafsaleonline.com/ abercrombie and fitch scarf] , The following is a overview of each of these network devices.		<poem>
	INDIVIDUAL COMPUTERS: The personal computer is usually a pc, a work station or a laptop. The private computers are most widely used in a organization or personal use. The individual computers would be the most typical kinds of the microcomputers.		Saudade do não vivido
	SERVER: A server is a computer on a network, which process request and is accustomed to share the data and resources one of the other computers in a network. A server stores all the information you need and offers the different services like, workstation computer’s logon access, internet sharing, print sharing, disk space sharing etc. There are various kinds of servers e.g File and print server, database server, proxy server, Fax server, backup server etc. A database server stores all the data and software, which may associated with the certain database and it allows other network devices to access and process the database queries. Personal files server is used to keep the information associated with a user about the network and a print server manages a number of printers inside a network. Similarly a network server is really a server that manages the network traffic.		Saudade do sonho
	NETWORK INTERFACE CARD: Network interface cards are that come with the pc or other network devices and are accustomed to supply the connectivity between your two computers. Each network card is created specifically for that different types of the network like Ethernet, FDDI, Token Ring and Wireless Networks. The Network card operates on the foremost and second layers of the OSI models i.e Physical layer and datalink layer specifications. NIC basically defines the physical connection methods and the control signals providing you with the timings from the data transfer over the network.		que restou in vitro
	HUBS: Hub is a simplest network device. The purpose of the hub is broadcasting i.e data is forwarded for the all ports of a hub, whether or not the data was meant for the specific systems within the network or otherwise. Computers inside a network are attached to a hub with a twisted pair (CAT5) cables. There's two types of the hubs. 1. Active Hubs. 2. Passive Hubs.
	SWITCHING HUB: The Switching hub (also known as “switch” is easily the most advance form of the basic hub. In a basic hub all the computers are connected with the hub and the speed from the network is defined by the slowest computer network card connected. For example for those who have 10/100 Mbps cards in a network in support of one card of 10Mbps speed then your system cannot improve your speed than the 10 Mbps. Now if you've got a switching hub inside a network, it'll allow all of the faster connections in the network to remain at the higher speed but still interact with the 10Mbps system.

	SWITCHES: Switch is really a intelligence device than hub. Switch is a layer 2 device. Swith provides the same be the hub or perhaps a bridge however it has the advance functionality of connecting both computers together temporarily. Switch contains the switch matrix or switch fabric that can connect and disconnect ports. Unlike hubs, switch only transmit or forwards the information to the destined computer also it doesn't broadcasts the information to all its ports.
	~~MODEMS~~: Modems are the devices, which are accustomed to translate digital data into the analog format and vice versa. It performs the two main functions. Modulation and demodulation. A modulated data can travel over the conventional telephone lines. The modem modulates the signals in the sending end and demodulates in the receiving end. Modems are required for various kinds of the access methods such ISDN, DSL and 56K data modem. Modem can be the internal devices that plug in to the expansion slots in a system or can be external devices that plug into the serial or USB ports. In Laptops, PCMCIA cards can be used for this purpose and several new laptops getting the built in integrated modems. The specialized devices are designed for use within the systems for example handheld computers. In ISPs in which the large scaled modems are required, rack-mounted modems are used.
	ROUTERS: Routers route the data between two logically and physically different networks. A Router has the capability to determine the destination address for that data and therefore offers the easiest way for that data to continue its journey. Router gets this capability through its software called routing software. Unlike Switches and Bridges, which use hardware configured MAC address to look for the destination from the data, router uses logical network address for example Ip to make a decision in determining the destination of the data.
	GATEWAY: A gateway performs the function of translating the data from one format to another format without changing the information itself. A gateway could be a device, system, software. Some type of computer with two NIC cards can function as a gateway. Router provides a gateway e.g a router that routes the data from a IPX network to a IP network is technically a gateway. The same can be said of translational switch converts from the Ethernet network to a token ring network.
	CABLES: There are two most common kinds of the cables. 1. 10baseT and 10base2. 10baseT is a four paired cable. 10baseT has further two types 1. UTP (unshielded twisted pair) and a pair of. STP (shielded twisted pair. STP is most secure cable covered with the silver coated twisted paper to protect the cable. On the other end Thin 10base2 appears like the copper coaxial cabling that usually used to connect Tv's and VCR. 10baseT/Cat5 cables are most frequently used cables to connect the computers. It has the connector, (like a telephone connector) called RJ45 connector.
	~~Twisted pair cables are perfect for the small, medium or large networks. My recommendation for using cables for networking is to use 10baset/Cat5 cables~~
