The internet is a network of interconnected computers and devices that communicate with each other using protocols. It enables the sharing of information, such as web pages, files, and media, through wired or wireless connections.

What is the difference between wired and wireless internet connections?

Wired internet connections typically use physical cables, such as fiber optic or coaxial cables, to transmit data at higher speeds and reliability. Wireless connections use radio waves to transmit data, offering more mobility but generally lower speeds and higher latency.

What is a browser, and which one is most commonly used?

A browser is a software application used to access and view websites. Chrome is one of the most widely used browsers, known for its speed and features such as support for multiple tabs, extensions, and synchronization across devices.

What are internet protocols, and why are they important?

Internet protocols are a set of rules that determine how data is transmitted and received over the internet. They ensure that communication between devices is standardized and efficient. Common protocols include TCP/IP for data transmission and HTTP/HTTPS for web browsing.

What is TCP/IP, and what is its role in the internet?

TCP/IP (Transmission Control Protocol/Internet Protocol) is the fundamental suite of protocols used for data transmission over the internet. TCP handles the reliable transmission of data, while IP manages the routing of data to its correct destination.

What is a web browser's function in internet usage?

A web browser serves as an interface for users to access and interact with the web. It retrieves, displays, and allows navigation through websites using URLs, supporting the viewing of multimedia content, documents, and more.

What are the different devices that can connect to the internet?

A wide variety of devices can connect to the internet, including computers, smartphones, tablets, printers, IoT (Internet of Things) devices, and even home appliances. These devices use different operating systems but can communicate through the internet if connected properly.

How does the World Wide Web differ from the internet?

The internet is the global network that connects millions of computers and devices, while the World Wide Web is a system of interlinked hypertext documents and resources accessed through the internet. The WWW is a subset of the internet, providing a way to view and interact with multimedia content.
