Session 3: FAQs and Related Articles
FAQs:
1. What is the difference between the OSI model and the TCP/IP model? The OSI model is a theoretical seven-layer model, providing a conceptual framework. The TCP/IP model is a practical four-layer model reflecting actual internet protocols. The TCP/IP model is more commonly used in practice.
2. What are the key differences between TCP and UDP protocols? TCP is connection-oriented, reliable, and ordered, while UDP is connectionless, unreliable, and unordered. TCP is suitable for applications requiring reliable data transfer, while UDP is used for applications where speed is prioritized over reliability.
3. How does IP addressing work? IP addresses are unique numerical labels assigned to devices on a network. They enable devices to communicate with each other. IP addresses are structured using IPv4 (32-bit) or IPv6 (128-bit) addressing schemes. Subnetting divides a network into smaller subnetworks for efficient network management.
4. What are some common network security threats? Common threats include malware, denial-of-service attacks, man-in-the-middle attacks, and unauthorized access. These threats can compromise data integrity, confidentiality, and availability.
5. How does DNS work? DNS (Domain Name System) translates human-readable domain names (like google.com) into machine-readable IP addresses. This allows users to access websites and services using easy-to-remember names.
6. What is the role of routers in a network? Routers forward data packets between different networks. They determine the optimal path for data packets to reach their destination using routing protocols.
7. What are firewalls and how do they protect networks? Firewalls act as barriers between a network and external networks, controlling inbound and outbound network traffic based on predefined rules. They help prevent unauthorized access and malicious traffic.
8. What is the Internet of Things (IoT)? IoT refers to the network of physical objects embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the internet.
9. What is the future of computer networking? The future of computer networking involves increased automation, Software Defined Networking (SDN), Network Function Virtualization (NFV), and the continued growth of the Internet of Things (IoT), requiring ever more sophisticated security measures.
