FAQs on PPT: Internet Protocol - Computer Awareness and Proficiency - SSC CGL

1. What is the Internet Protocol and why is it important?
Ans. The Internet Protocol (IP) is a fundamental set of rules that govern how data is sent and received over the internet. It is responsible for addressing and routing packets of data so that they can travel across networks, ensuring they reach their intended destinations. IP is crucial because it enables communication between devices on different networks, which is essential for the functioning of the internet.
2. What are the two main versions of Internet Protocol?
Ans. The two main versions of Internet Protocol are IPv4 (Internet Protocol version 4) and IPv6 (Internet Protocol version 6). IPv4 uses a 32-bit address scheme allowing for approximately 4.3 billion unique addresses, while IPv6 uses a 128-bit address scheme, vastly increasing the number of available addresses to accommodate the growing number of devices connected to the internet.
3. How does Internet Protocol handle data transmission?
Ans. Internet Protocol handles data transmission by breaking down messages into smaller packets, each containing a header with addressing information and the actual data. These packets are sent independently over the network and can take different paths to reach the destination, where they are reassembled in the correct order to form the original message. This packet-switching method enhances efficiency and reliability in data transmission.
4. What is the difference between TCP and UDP in relation to Internet Protocol?
Ans. TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are two protocols that operate on top of the Internet Protocol. TCP is connection-oriented, ensuring reliable and ordered delivery of data packets, which makes it suitable for applications like web browsing and email. In contrast, UDP is connectionless and does not guarantee delivery or order, making it faster and more efficient for applications like video streaming and online gaming, where speed is more critical than reliability.
5. How do IP addresses work, and why are they essential?
Ans. IP addresses are unique numerical labels assigned to each device connected to a network, identifying them on the internet. They function as addresses for data packets, allowing devices to locate and communicate with each other. IP addresses are essential for routing traffic, ensuring that data sent from one device can reach another device accurately, thus enabling seamless communication over the internet.
