These frequently asked sample questions on Computer are given with correct choice of answer that you can check instantly. 10. Answer: In a computer network, to enable data transmission from one computer to another, the network devices send messages in the form of packets. But the Internet has made it all so easy. Answer: Network is defined as a set of devices connected to each other using a physical transmission medium. Explanation: The community cloud allows systems and services to be accessible by a group of organizations. Answer: An IP address has 4 sets (octets) of numbers each with a value up to 255. Many will most likely get a 100% which means they definitly did their home work. Routers send the information in terms of data packets and when these data packets are forwarded from one router to another router then the router reads the network address in the packets and identifies the destination network. VPN keeps company information secure against any potential intrusion. Most Frequently asked Networking Interview Questions and Answers with Pictorial Representation for your easy understanding: In this advanced technology world, there are none who have never used the Internet. Translating the names into numbers or IP address is named as a Forward lookup. The main disadvantage of the star topology is that all the devices of the network are dependent on a single point (hub). And more than two links located nearby form a topology.
