1 :: What is network?
A network is a set of devices connected by physical media links. A network is recursively is a connection of two or more nodes by a physical link or two or more networks connected by one or more nodes.
2 :: Explain Link?
At the lowest level, a network can consist of two or more computers directly connected by some physical medium such as coaxial cable or optical fiber. Such a physical medium is called as Link.
3 :: What is node?
A network can consist of two or more computers directly connected by some physical medium such as coaxial cable or optical fiber. Such a physical medium is called as Links and the computer it connects is called as Nodes.
4 :: Explain a gateway or Router?
A node that is connected to two or more networks is commonly called as router or Gateway. It generally forwards message from one network to another.
5 :: Explain point-point link?
If the physical links are limited to a pair of nodes it is said to be point-point link.
6 :: Tell us multiple access?
If the physical links are shared by more than two nodes, it is said to be Multiple Access.
7 :: Describe the advantages of distributed processing?
☛ Security/Encapsulation
☛ Distributed database
☛ Faster Problem solving
☛ Security through redundancy
☛ Collaborative Processing

8 :: Tell me the criteria necessary for an effective and efficient network?
☛ Performance:
It can be measured in many ways, including transmit time and response time.
☛ Reliability:
It is measured by frequency of failure, the time it takes a link to recover from a failure, and the network's robustness.
☛ Security:
Security issues includes protecting data from unauthorized access and viruses.
