The other options listed, Microsoft Windows, Apple OS X, and Linux, are all examples of computer operating systems that provide the foundation for running software applications like Photoshop.
4.
In what form does the Internet move information between users’ computers?
Correct Answer
A. Data packets
Explanation
The Internet moves information between users' computers in the form of data packets. Data packets are small units of data that are transmitted over the network. They contain a portion of the information being sent, along with addressing information that allows them to be routed to the correct destination. This method of breaking down data into packets allows for efficient transmission and ensures that large amounts of data can be sent and received reliably.
5.
Which of the following is a computer operating system?
Correct Answer
A. Linux
Explanation
Linux is a computer operating system. It is an open-source operating system based on the Unix operating system. It is widely used in servers, mainframe computers, and embedded systems. Linux provides a stable and secure platform for running applications and managing hardware resources. It is known for its flexibility, scalability, and community-driven development. Many distributions of Linux are available, such as Ubuntu, Fedora, and Debian, catering to different user requirements. Linux has a command-line interface and a graphical user interface, making it accessible to both experienced and novice users.
6.
Which of these operating systems is made by Microsoft?
Correct Answer
D. Windows
Explanation
Windows is an operating system made by Microsoft. It is one of the most widely used operating systems in the world and is known for its user-friendly interface and compatibility with a wide range of software and hardware. Unlike Linux, which is an open-source operating system, Windows is a proprietary operating system developed and owned by Microsoft. OS X, on the other hand, is the operating system used by Apple computers, and CP/M is an older operating system that was popular in the 1970s and 1980s.
7.
Which of these is not a computer font?
Correct Answer
D. Windows
Explanation
Garamond, Times, and Helvetica are all well-known computer fonts that are commonly used in various applications and operating systems. However, Windows is not a computer font but rather an operating system developed by Microsoft. It is important to note that operating systems may come with a default set of fonts, including fonts like Garamond, Times, and Helvetica, but the operating system itself is not considered a font.
8.
Which of these relates to a computer?
Correct Answer
D. Megabyte
Explanation
A megabyte is a unit of digital information storage commonly used in computing. It represents a large amount of data, approximately equal to one million bytes. In contrast, the other options (megaton, macrame, and megaphone) do not directly relate to computers. Megaton refers to a unit of explosive power, macrame is a form of textile art, and a megaphone is a device used to amplify sound. Therefore, the correct answer is megabyte.
9.
What is a word relating to transferring electronic data?
Correct Answer
C. Download
Explanation
The word "download" relates to transferring electronic data. It refers to the process of receiving or retrieving data from a remote system, usually a server, to a local device, such as a computer or smartphone.
10.
A computer cannot 'boot' if it does not have the
Correct Answer
C. Operating System
Explanation
A computer cannot 'boot' if it does not have the operating system. The operating system is responsible for managing the computer's hardware and software resources, including the boot process. During booting, the operating system is loaded into the computer's memory, allowing it to control the hardware and initiate the startup process. Without an operating system, the computer would not have the necessary instructions and resources to start up and perform any tasks.
11.
What do you call the programs that are used to find out possible faults and their causes?
Correct Answer
C. Diagnostic software
Explanation
Diagnostic software refers to programs that are specifically designed to identify and analyze potential faults or problems in a system or device. These programs are used to diagnose and troubleshoot issues by running various tests and scans to determine the cause of the problem. They help in identifying faults and their causes, allowing users to effectively resolve any issues and maintain the proper functioning of their systems.
12.
The technology that stores only the essential instructions on a microprocessor chip and thus enhances its speed is referred to as
Correct Answer
B. RISC
Explanation
RISC stands for Reduced Instruction Set Computer. It is a type of microprocessor architecture that focuses on simplicity and efficiency by using a small set of basic instructions. RISC processors have a smaller and more streamlined instruction set compared to CISC (Complex Instruction Set Computer) processors. This allows RISC processors to execute instructions more quickly, resulting in enhanced speed and performance. Therefore, RISC is the technology that stores only the essential instructions on a microprocessor chip and enhances its speed. CD-ROM and Wi-Fi are unrelated technologies to microprocessor architecture.
