NETWORK DEVICES MODEM HUB SWITCH ETHERNET CARD REPEATER RJ-45 CONNECTOR GATEWAY

Slide 3: 

MODEM It is a computer peripheral that allows you to connect and communicate with other computer via telephone line. Modem changes the digital data from your computer into analog data, a format that can be carried over telephone lines. In the sane the the modem receiving the call then changes the analog signal back into digital data that the computer can understand.

Slide 4: 

EHTERNET CARD Type of LAN card developed by Xerox Corp. along with DEC and Intel. It uses a Bus or Star topology. Supports data transfer rates of upto 10 Mbps.

Slide 5: 

RJ-45 CONNECTOR The Registered Jack-45 connector is commonly used for network cabling and for telephony applications. It is an eight wire connector which is commonly used to connect computers on the local area networks, especially Ethernets. It is similar to telephone connector RJ-11 except that it has eight wires as compared to 4 in RJ-11.

Slide 6: 

HUB It is used to connect several computers together. A network device the information flow is accumulated and then distributed to various groups and users. It can be between users on the same LAN and users on different LANs. It is often used in Star or Ring topology.

A network switch is a computer networking device that connects network segments.Network switches appear nearly identical to network hubs, but a switch contains more "intelligence" (and comes with a correspondingly slightly higher price tag) than a network hub. Network switches are capable of inspecting data packets as they are received, determining the source and destination device of that packet, and forwarding it appropriately. By delivering each message only to the connected device it was intended for, a network switch conserves network bandwidth and offers generally better performance than a hub.Switches differ from hubs in that they can have ports of different speed. :

Slide 8: 

ROUTER A router is a computer whose software and hardware are usually tailored to the tasks of routing and forwarding. This device routes the information packet between two or more physically or logically connected networks. It is different from Bridge as this uses logical address while bridge uses physical address.

Slide 9: 

BRIDGE It is a device that lets you link two same networks together. Same networks mean networks with same protocol. REPEATER It is a device that amplifies and restores the power of a signal being transmitted on the network. It is used in long network lines.

Slide 10: 

GATEWAY This device usually a server is used to communicate between dissimilar networks i.e. networks with different protocols. e.g. to connect a LAN with Novell Netware with another LAN with Microsoft NT. In enterprises, the gateway is the computer that routes the traffic from the workstation to the outside world. In homes, the gateway is the ISP that connects the user to the Internet.
