1) What is Routing?
Routing is the process of finding a path on which data can pass from source to destination. Routing is done by a device called routers, which are network layer devices.
2) What is the purpose of the Data Link?
The job of the Data Link layer is to check messages are sent to the right device. Another function of this layer is framing.
3) What is the key advantage of using switches?
When a switch receives a signal, it creates a frame out of the bits that were from that signal. With this process, it gains access and reads the destination address, after which it forwards that frame to the appropriate port. This is a very efficient means of data transmission, instead of broadcasting it on all ports.
4) When does network congestion occur?
Network congestion occurs when too many users are trying to use the same bandwidth. This is especially true in big networks that do not resort to network segmentation.
5) What is a Window in networking terms?
A Window refers to the number of segments that are allowed to be sent from source to destination before an acknowledgment is sent back.
6) Does a bridge divide a network into smaller sections?
Not really. What a bridge actually does is to take the large network and filter it, without changing the size of the network.
