Q & A

What is the internet and how does it work?

The internet is a vast interconnected network of computers that allows users to communicate and exchange data. It connects smaller local networks, such as LANs, to form a larger global network, enabling users to access information and communicate quickly. The internet also facilitates global collaboration and real-time data sharing.

What is the significance of the term WWW?

WWW stands for World Wide Web, which refers to the system of interlinked hypertext documents accessed through the internet. It stores data and information in the form of web pages, and users can navigate these pages via browsers.

How does cloud computing relate to the internet?

Cloud computing allows for the storage of large amounts of data online rather than on local machines. It provides users with the ability to store, access, and share files over the internet, thus making file management more efficient and accessible from anywhere.

What is a computer network?

A computer network refers to a group of interconnected computers that share resources such as data, files, or printers. Networks can be used within an organization or between individuals and are essential for tasks requiring multiple devices to work together efficiently.

What is the difference between a server and a client in a computer network?

In a computer network, a server is a powerful computer that provides services or resources to other computers, known as clients. The server manages data and responds to client requests, while the client accesses these resources.

What role does a gateway play in a network?

A gateway is a device or software that connects two networks with different communication protocols, enabling data transfer between them. It acts as a translator or mediator, allowing one network to communicate with another that may not use the same protocols.

What is a web server and how does it work?

A web server is software (or a physical machine) that handles requests for web pages. When a browser sends a request for a website, the web server processes the request and sends back the appropriate files, such as HTML documents or images, to be displayed in the browser.

What are some of the benefits of using a computer network?

The benefits of using a computer network include resource sharing (like printers and files), increased reliability (as data is stored across multiple devices), cost savings (reducing the need for duplicate equipment), and enhanced communication (through file sharing and collaboration tools).

What are the different types of computer networks?

Computer networks can be categorized based on their geographical scope. These include Local Area Networks (LAN), Metropolitan Area Networks (MAN), Wide Area Networks (WAN), and the internet. Networks can also be either wired (using cables) or wireless (using electromagnetic waves).

What is the difference between LAN and MAN?

A Local Area Network (LAN) is confined to a small geographical area, such as a building or school, while a Metropolitan Area Network (MAN) covers a larger area, such as several offices within a city. MANs are typically used by organizations that need to connect multiple buildings or locations within a city.
