Aim: Study of following
Network Devices in Detail
- Repeater
- Hub
- Switch
- Bridge
- Router
- Gate Way
Apparatus (Software):
No software or hardware needed.
Procedure: Following
should be done to understand this practical.
LAN DEVICES
NIC Card-
A network interface controller (NIC) card is a computer hardware component that connects a computer to a computer network. it is also known as a network interface card, network adapter, LAN adapter, Ethernet card) is a computer hardware component that connects a computer to a computer network.You can see the NIC card picture given below.
Hub
Hub is a device that is
used to connect more than two computers together for data file, resource
sharing etc in the network.
Switch
A switch is a telecommunication device that
receives a message from any computer/device connected to it and then transmits
the message only to the device for which the message was sent. This makes the
switch a more intelligent device than a hub (which receives a message and then
transmits it to all the other devices on its network). Switch is also known as
multiport bridge.
Bridge –
Bridge is similar to Switch. Bridge has less number of connecting ports than switch
WAN DEVICES
Router
Routers are the physical devices that connect
multiple different networks together. As its name tells us that this device
defines the route for data packets. Like by which route the data will be
forwarded if more than routes are available.
Modem(Wireless/Wired)
Modems are networking devices that convert
analog and digital data for computer-to-computer communication. Analog data
used on telephone lines and the digital form used on computers. It is Also
Known As: modulator demodulator
