Keywords

💡Internet

The Internet is a global network that interconnects computers and devices, enabling them to share information and communicate with one another. It is the foundational infrastructure that supports a wide range of activities, from email and social media to cloud computing and remote work. In the video, the Internet is described as a vast network connecting computers worldwide, facilitating data sharing and communication.

💡World Wide Web (WWW)

The World Wide Web, often referred to simply as the Web, is a system of interlinked hypertext documents that are accessed via the Internet. It is a collection of websites that contain text, images, and other multimedia resources. The video emphasizes that the Web is accessed through the Internet and is composed of various websites, highlighting its role in providing information and services.

💡End Systems

End systems are the devices, such as computers and smartphones, that are connected to the Internet and use its services. They are the endpoints where users interact with the network. The video mentions end systems as part of the Internet's components, indicating that they are the devices through which individuals access the Internet and its services.

💡Routers and Switches

Routers and switches are networking devices that forward data packets between networks. They play a critical role in directing traffic and ensuring that data reaches its intended destination. In the context of the video, these devices are part of the Internet's infrastructure, facilitating the flow of information between different networks.
