FAQs on Basics of Network- 2 Video Lecture - Crash Course: Electronic Communication Engineering (ECE) - Electronics and Communication Engineering (ECE)

1. What are the basic components of a network?
Ans. The basic components of a network include computers, routers, switches, servers, cables, and network interface cards (NICs). These components work together to enable communication and data transfer between devices in a network.
2. What is the difference between a local area network (LAN) and a wide area network (WAN)?
Ans. A LAN is a network that covers a small geographical area, such as a home, office, or building. It typically uses Ethernet cables or Wi-Fi to connect devices within the area. On the other hand, a WAN is a network that covers a larger geographical area, such as multiple cities or countries. It uses leased lines, satellite links, or internet connections to connect devices across different locations.
3. What is a router and what is its role in a network?
Ans. A router is a networking device that connects multiple networks together. It receives data packets from one network and forwards them to the appropriate network based on the destination IP address. It also helps in determining the best path for data transmission and ensures efficient data routing within the network.
4. What is the purpose of an IP address in a network?
Ans. An IP address is a unique numerical identifier assigned to each device in a network. It helps in identifying and locating devices within a network or across the internet. IP addresses are essential for proper data routing and communication between devices in a network.
5. What is the difference between TCP and UDP protocols?
Ans. TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are two different transport layer protocols used in network communication. TCP provides reliable and ordered delivery of data packets, ensuring error detection and correction. UDP, on the other hand, is a connectionless protocol that does not guarantee delivery or order of packets but offers faster transmission. TCP is commonly used for applications that require reliable data transfer, such as web browsing and file downloads, while UDP is used for real-time streaming, online gaming, and voice/video communication.
