What are routers?

Routers can connect two or more network segments. These are intelligent network devices that

store information in its routing table such as paths, hops and bottlenecks. With this info, they are

able to determine the best path for data transfer. Routers operate at the OSI Network Layer.

What is point to point link?

It refers to a direct connection between two computers on a network. A point to point connection

does not need any other network devices other than connecting a cable to the NIC cards of both

computers.

What is anonymous FTP?

Anonymous FTP is a way of granting user access to files in public servers. Users that are

bits.

 What is the maximum length allowed for a UTP cable?

A single segment of UTP cable has an allowable length of 90 to 100 meters. This limitation can

be overcome by using repeaters and switches.

 What is data encapsulation?

Data encapsulation is the process of breaking down information into smaller manageable

chunks before it is transmitted across the network. It is also in this process that the source and

destination addresses are attached into the headers, along with parity checks.

Describe Network Topology

Network Topology refers to the layout of a computer network. It shows how devices and cables

are physically laid out, as well as how they connect to one another.
