What are the different Networking devices and explain each and every function and related OSI model layers.
There are three main networking devices hub,switch, router.
1. Hub is layer one device in OSI Model.
2. Switch is layer two device in OSI Model.
3. Router is layer device three in OSI Model.
Networking devices includes:
NIC (Network Interface Card) -an expansion card attached to a computer motherboard the connects network medium to the computer bus.
Hub -a device that connects all segments of a network together.
Router - a device that connects dissimilar network segments into one and selects path data travels through each network segment.
Switch - Similar to a hub but does not rebroadcast message to all computers in network but between the sender and receiver.
The OSI model is made up of seven layers; each layer with some associated protocols. The OSI model is only a logical model and provides guidelines of how network should be implemented. The layers are;
Modems -meaning MODULATION DEMODULATION, is a network device that changes data from a digital form into analog form and from an analog form into digital for transmission over an appropriate communication medium.
Gateways, a combination of hardware and software that connects dissimilar network environments.
MAU (Multi station Access Unit) - Has similar functionality to that of a hub but used in the Token Ring Network type. It creates data paths that form the ring in a token network.
Router - Combines the functionality of a router and that of a bridge, found on the Network layer although it’s not used nowadays.
Here is the solution.
On the client computer running Serial/IP.
