Computer Network GATE Questions with Answers
Question 1: What is the difference between a router and a switch in a computer network?
Answer: A router is a networking device that forwards data packets between computer networks, while a switch is a device that connects multiple devices within a single network. The main difference between them is that routers operate at the network layer and can connect networks of different types, while switches operate at the data link layer and are used to connect devices within the same network.
Question 2: What is TCP/IP and how does it work in computer networks?
Answer: TCP/IP is a suite of communication protocols that govern the transmission of data over the Internet. It consists of two main protocols: Transmission Control Protocol (TCP) and Internet Protocol (IP). TCP provides a reliable, ordered, and error-checked delivery of data packets, while IP handles the routing of packets between network nodes. Together, TCP/IP enables computers to communicate with each other over the internet.
Question 3: What is the purpose of DNS in computer networks?
Answer: DNS (Domain Name System) is a system that translates human-readable domain names into IP addresses that computers can understand. It enables users to access websites and other resources on the internet using easy-to-remember domain names instead of hard-to-remember IP addresses.
Question 4: What is the difference between symmetric and asymmetric encryption in computer networks?
Answer: Symmetric encryption is a method of encryption where the same key is used to encrypt and decrypt data. This means that both the sender and receiver must have access to the same key. Asymmetric encryption, on the other hand, uses a public key and a private key to encrypt and decrypt data. The public key is used to encrypt data, while the private key is used to decrypt it.
Question 5: What is a firewall and how does it work in computer networks?
Answer: A firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules. It can either allow or block traffic based on criteria such as IP addresses, port numbers, and protocols. Firewalls can help protect networks from unauthorized access, viruses, and other security threats.
