To provide a detailed solution, let's break down the question and answer choices:
Question: Connected computers in a ______ get their resources from a common source called _____, which is also a type of a computer.
Answer Choices:
A. network, server
B. Server, Network
C. server, UPS
D. network, UPS
Explanation:
The correct answer is A. network, server.
- Network: A network refers to a group of connected computers that can communicate and share resources with each other.
- Server: In a network, a server is a computer or a system that provides resources and services to other connected computers. It acts as a central repository for files, applications, and data that can be accessed by the networked computers.
Therefore, the connected computers in a network get their resources from a common source called a server, which is also a type of computer.
The other answer choices (B, C, and D) are incorrect because they either mix up the order of the terms or include unrelated terms like UPS (Uninterruptible Power Supply), which is not the common source of resources in a network.

A website is a collection of related web pages or linked documents, including text and multimedia content such as graphics, animation, video and audio, typically identified with a common domain name, and published on at least one web server.

The information given about Mr. X and Mr. Y is as follows:
Mr. X: “I am a bunch of pages of information connected to each other around the globe”.
