Networking Interview Questions and Answers for 2024
Categories: Hardware & Networking
Q1. What is Network Topology? Ans. This is among the important networking interview questions. Network topology is the physical or logical arrangement in which the devices or nodes of a network (e.g. computers, printers, servers, hubs, switches, routers, etc.) are interconnected over a communication medium. It consists of two parts – the physical topology, which is the actual arrangement of the cables (the media), and the logical topology, which defines how the hosts access the media. Q2. What are ‘client’ and ‘server’ in a network? Ans. Clients and servers are separate logical entities that work together over a network to accomplish a task. A client application is the element of communication that requests or requests a network service, for example, accessing a web page, or downloading a file, or sending an email. A server application is the element of communication that responds to customer requests, providing the required service, that is, sending the web page or the requested file or email. Q3. What is a ‘frame relay’, and which layer does it operate? Ans. Frame Relay is a data link layer digital packet-switched network protocol technology designed to connect local area networks (LANs) and transfer data over wide area networks (WANs). Frame Relay shares some of the same underlying technology as X.25. Q4. What are the different features of Frame Relay? Ans. The different features of Frame Relay are: a. Frame Relay is a connectionless service, which means that every data packet that passes over the network contains address information b. Frame Relay is a service that is provided with a variety of speeds from 56 Kbs to 25 Mbs. Although the speeds most used for the service are currently 56 Kbs and 1,544 Mbs c. The frames are of variable length and go up to 4,096 bytes Q5. How does a Frame Relay Work? Ans. Frame Relay supports the multiplexing of traffic from multiple connections over a shared physical link. It uses hardware components that include router frames, bridges and switches to pack data into individual frame relay messages. Q6. What is ‘beaconing’? Ans. Beaconing is the process that allows a network to self-repair network problems. This is among the important networking interview questions; you must also prepare for the related terminologies. Q7. What is an IP address? Ans. An Internet Protocol address (IP address) is a numerical unique address of a device in a network. IP is a datagram-oriented connectionless protocol, therefore, each packet must contain a header with the source IP address, the destination IP address, and other data to be delivered successfully. There are two types of IPs – a. Private IP Address – A private IP address is a set of numbers assigned to each computer or system connected to a private network. An example of a private IP address is your mobile phone or your home router, which has a default local address. b Public IP Address – Public IP addresses are global addresses visible to anyone browsing the Internet. A user needs an internet connection to connect to such devices. Q8. What is ‘bandwidth’? Ans. The limited range of frequencies of signals that a line can carry is called the bandwidth. Bandwidth is often confused with Internet speed when the volume of information can be sent over a connection in a measured amount of time, calculated in megabits per second (Mbps).
