The type of error checking to be used. Uni-casting —Here one to one communication occurs Multi-casting —Here one to many communication occurs Broadcasting —here one to all communication occurs. Answer: Here nodes and servers share data roles. Nodes are defined as clients.
To control access servers are used. The server is the most important part computer. Packets sent to the hub. Again packets are sent by Hub to the destination. Advantages It is easy to set up in a network.
One single cable cannot crash the whole network. Disadvantages One single hub crashing downs the whole network It uses a lot of cables It is the most common topology 9 What is RING connectivity in computer network? Token is used for transferring data from computers.
Advantages Time for sending data is known. There are three ranges of IP addresses that have been reserved for IP addresses.
They are not valid for use on the internet.
If you want to access internet on these private IPs, you must have to use proxy server or NAT server. A public IP address is an address taken by the Internet Service Provider which facilitates you to communication on the internet.
This feature is generally found in Microsoft operating system. Anonymous FTP is used to grant users access to files in public servers.
Users which are allowed access to data in these servers do not need to identify themselves, but instead log in as an anonymous guest. A protocol is a set of rules which is used to govern all the aspects of information communication.
First is directly used by the users and the second supports application programs. The Domain Name System is the second type supporting program that is used by other programs such as to find the IP address of an e-mail recipient. A link is connectivity between two devices which includes the cables and protocols used in order to make communication between devices.
OSI reference model: OSI reference model is an ISO standard which defines a networking framework for implementing the protocols in seven layers.
These seven layers can be grouped into three categories:. The OSI physical layer is used to convert data bits into electrical signals and vice versa. On this layer, network devices and cable types are considered and setup. OSI session layer provides the protocols and means for two devices on the network to communicate with each other by holding a session.
This layer is responsible for setting up the session, managing information exchange during the session, and tear-down process upon termination of the session. It is a set of protocol layers that is designed for exchanging data on different types of networks. You can ping devices using its IP address or name. Sneakernet is the earliest form of networking where the data is physically transported using removable media.
A switch receives packets faster than the shared link. It can accommodate and stores in its memory, for an extended period of time, then the switch will eventually run out of buffer space, and some packets will have to be dropped.
This state is called a congested state. In Networking, multiplexing is the set of techniques that is used to allow the simultaneous transmission of multiple signals across a single data link. Address sharing provides security benefit instead of routing. This article is useful for those who are attending the interview on Networking.
As networking is a complex topic, one needs to be careful while answering the questions in an interview. If you go through the interview questions on networking of this article, you can easily face the interview.
Skip to content. A network is a set of devices that are connected with a physical media link. In a network, two or more nodes are connected by a physical link or two or more networks are connected by one or more nodes. A network is a collection of devices connected to each other to allow the sharing of data.
Example of a network is an internet. An internet connects the millions of people across the world. The types of topologies are:
