1. OSI Model Questions

Question 1: What is the significance of the OSI model in computer networking?

Answer: The OSI (Open Systems Interconnection) model is a conceptual framework used to understand and describe how different network protocols interact with each other. It consists of seven layers, each with its own unique functionalities, ensuring seamless communication and data transfer across networks.

Question 2: Which layer of the OSI model is responsible for routing and logical addressing?

Answer: The Network layer (Layer 3) is responsible for routing packets and logical addressing. It determines the best path for data transmission, using routing protocols such as OSPF (Open Shortest Path First) and BGP (Border Gateway Protocol).

2. TCP/IP Protocols

Question 3: What is the function of the Transmission Control Protocol (TCP) in the TCP/IP suite?

Answer: TCP is responsible for ensuring reliable and ordered delivery of data packets over IP networks. It establishes a connection-oriented communication by establishing a reliable channel between source and destination devices. TCP handles packet acknowledgments, retransmission of lost packets, and flow control to prevent data overflow.

Question 4: Which protocol operates at the Application layer of the TCP/IP model?

Answer: The Hypertext Transfer Protocol (HTTP) operates at the Application layer of the TCP/IP model. It is responsible for enabling communication between web browsers and web servers, facilitating the retrieval and display of web resources.

3. Network Security

Question 5: What is a firewall, and what is its purpose in a network?

Answer: A firewall is a network security device that monitors and controls incoming and outgoing network traffic. It acts as a barrier between an internal network and external networks, filtering traffic based on predetermined security rules. The firewall's purpose is to prevent unauthorized access, protect against malicious activities, and secure sensitive data.

Question 6: What is the difference between symmetric and asymmetric encryption algorithms?

Answer: Symmetric encryption algorithms use a single shared secret key for both encryption and decryption. They are faster and more suitable for bulk data encryption. Asymmetric encryption algorithms, on the other hand, use a pair of public and private keys. Public keys are used for encryption, while private keys are required for decryption. They provide better security but are slower compared to symmetric algorithms.

4. IP Addressing and Subnetting

Question 7: What is the purpose of subnetting, and how does it help in network management?

Answer: Subnetting allows the division of an IP network into smaller subnetworks called subnets. It helps in optimizing network performance, improving security, and efficient utilization of IP addresses. Subnetting also enables logical grouping of devices and simplifies network management by reducing broadcast domains and controlling network traffic.

Question 8: How do you calculate the number of available hosts in a subnet?

Answer: The number of available hosts in a subnet can be calculated using the formula (2^n) - 2, where 'n' represents the number of host bits. The subtracted 2 accounts for the network and broadcast addresses, which cannot be assigned to hosts.
