What is a web server?

• A. A type of database software
• B. A server that stores web pages and delivers them to users' browsers
• C. A network device that connects computers
• D. A software application for managing network security

Answer: (B)

A web server is specifically designed to store, process, and deliver web pages to users' browsers through the internet. When a user requests a web page by entering a URL into their browser, the web server retrieves the corresponding files and sends them to the user's device. This interaction typically utilizes the Hypertext Transfer Protocol (HTTP), which allows for communication between the server and the client (the user's browser).

The other options do not accurately define what a web server is. Database software, for instance, is focused on storing and managing data, and while some web servers may interact with databases, they serve distinct functions. A network device that connects computers generally refers to devices like routers and switches, which facilitate communication within a network, but this is separate from the specific role of a web server. Finally, software applications for managing network security, such as firewalls or antivirus programs, emphasize security measures rather than the delivery of web content, which is the primary purpose of a web server. Thus, choice B accurately encapsulates the essential role of a web server in the context of the internet.
