What is the Internet and how does it differ from the World Wide Web?
✔✔ The Internet is a global network of interconnected computers that communicate using
standard protocols, while the World Wide Web is a system of interlinked hypertext documents
and multimedia content accessed via the Internet using web browsers.
Explain the role of IP addresses in the Internet.
✔✔ IP addresses are unique numerical labels assigned to each device connected to the Internet.
They serve as the primary means for identifying and locating devices, enabling them to send and
receive data to and from other devices.
What is DNS, and why is it important for the functioning of the Internet?
✔✔ DNS (Domain Name System) translates human-readable domain names (like
www.example.com) into IP addresses that computers use to identify each other on the network.

,It is crucial for allowing users to access websites using easily memorable names rather than
numerical IP addresses.
Define HTTP and explain its purpose in web communication.
✔✔ HTTP (Hypertext Transfer Protocol) is the protocol used for transmitting data over the web.
It enables the transfer of web pages and other resources from a web server to a web browser,
allowing users to access and interact with websites.
What is packet switching, and how does it contribute to Internet data transmission?
✔✔ Packet switching is a method of data transmission where data is divided into small packets,
each of which may take a different route to reach the destination. It enhances network efficiency
and reliability by allowing multiple data transmissions to share the same network paths.
Describe the function of a router in a network.
✔✔ A router is a device that directs data packets between different networks or segments of a
network. It determines the best path for data to travel from the source to the destination and helps
manage traffic within and between networks.
2
, What is bandwidth, and how does it affect Internet performance?
✔✔ Bandwidth refers to the maximum amount of data that can be transmitted over a network
connection in a given time period. Higher bandwidth allows for faster data transfer rates and
better performance for activities such as streaming and downloading.
Explain the concept of latency and its impact on Internet usage.
✔✔ Latency is the delay between sending a request and receiving a response over the Internet.
High latency can lead to slower performance and delays in communication, affecting activities
such as online gaming and video conferencing.
What are protocols, and why are they essential for Internet communication?
✔✔ Protocols are standardized rules and conventions that define how data is transmitted and
received over a network. They ensure that different devices and applications can communicate
effectively and understand each other, facilitating reliable and consistent Internet interactions.
