Important Networking Interview Questions

Categories: Hardware & Networking

Q1. What is a client-server model?

Ans. The client-server model or architecture is a communication framework for network processes. This framework is distributed among service requestors, clients, and service providers. It offers them transparent access to applications, data, computing services or any other resource of the workgroup and/or across the organization on multiple platforms.  

Q2. What is TELNET?

Ans. TELNET is a client-service protocol on the internet or local area network, allowing a user to log on to a remote device and have access to it. This is among the most commonly asked networking interview questions. Technically, it is a bidirectional interactive text-oriented communication facility which uses a virtual terminal connection.

Q3. What is RIP?

Ans. In networking, RIP is an abbreviation for Routing Information Protocol. It is a simple protocol that exchanges information between the routers.

Q4. What is half-duplex?

Ans. It is the mode of communication between two devices. Here the data flows bi-directionally but simultaneously. A perfect example of a half-duplex is a walkie-talkie.

Q5. What is a full-duplex?

Ans. It is a mode of communication between two devices, and the data flow is bi-directional, too, but the flow is simultaneous. One of the examples of a full-duplex is a telephone.

Q6. What is netstat?

Ans. Netstat is a command-line utility program that provides information about a connection’s current Transmission Control Protocol /Internet Protocol (TCP/IP) settings.

Q7. What is a peer-peer process?

Ans. The processes on each machine that communicate at a given layer are called the peer-peer process.

Q8. What is anonymous FTP?

Ans. With the help of an anonymous FTP, users can be granted access to files in public servers. Users can log in as anonymous guests, thus the name.

Q9. What is NAT?

Ans. Network Address Translation is a protocol that allows a network device, usually a firewall, to assign a public address to a computer/s inside a private network.

Q10. What is NIC?

Ans. NIC is the abbreviation for Network Interface Card. It is a peripheral card with electronic circuitry. It is attached to a PC and connects to a network. NIC has its own MAC address and this identifies a PC on the network.

Q11. Explain NAT in networking.

Ans. Network Address Translation (NAT) is a protocol used to convert the IP address of the computer network into a local network to a single IP address. It takes all your local network devices and provides a single IP address to share a single connection to the internet. NAT is used as a router, computer, and firewall in a local network.

Q12. Explain NOS.

Ans. Short form for Network Operating System. Specialized software that provides connectivity to a computer such that it can communicate with other computers and devices on a network.
