The acronym PC stands for:
Correct Answer
B. Personal Computer
Explanation
The acronym PC stands for Personal Computer. This term refers to a computer that is designed for individual use, typically for tasks such as word processing, internet browsing, and gaming. The term "personal" emphasizes the individual ownership and use of the computer, distinguishing it from larger, more centralized computer systems. The term "computer" refers to the device's ability to process data and perform various tasks based on instructions given to it.
2.
Another name for supercomputer is:
Correct Answer
C. Monster Computer
Explanation
The term "supercomputer" refers to a high-performance computing system that is capable of processing vast amounts of data and performing complex calculations at incredibly fast speeds. The term "monster" is often used figuratively to describe something that is exceptionally large, powerful, or impressive. Therefore, "Monster Computer" is an appropriate alternative name for a supercomputer as it conveys the idea of a powerful and formidable computing machine.
3.
This computer is a multiprocessing computer system that is smaller and slower than a mainframe:
Correct Answer
C. Minicomputer
Explanation
A minicomputer is a suitable explanation for the given answer because it fits the description of a multiprocessing computer system that is smaller and slower than a mainframe. Minicomputers were commonly used in the 1960s to 1980s and were smaller in size compared to mainframes, making them more affordable and accessible for smaller organizations. They were capable of performing multiple tasks concurrently, but were slower and had less processing power compared to mainframes. Therefore, a minicomputer is the correct answer in this context.
4.
This computer is mainly used in homes for recreation:
Correct Answer
A. Personal Computer
Explanation
A personal computer is mainly used in homes for recreation because it provides individuals with the ability to engage in a variety of recreational activities such as gaming, watching movies, browsing the internet, and listening to music. Personal computers are designed to be user-friendly and accessible, making them suitable for non-technical users who primarily use them for entertainment purposes. In contrast, mainframe computers and minicomputers are typically used in large organizations for complex data processing tasks and are not typically found in homes for recreational purposes.
5.
Complex scientific research is usually done using:
Correct Answer
B. Supercomputer
Explanation
Supercomputers are used for complex scientific research due to their ability to process large amounts of data and perform complex calculations at incredibly high speeds. They have a high processing power, large memory capacity, and parallel processing capabilities, allowing scientists to analyze and simulate complex phenomena such as climate modeling, genetic research, and nuclear simulations. Their advanced computational capabilities make them essential tools for scientific research that requires massive data processing and complex simulations.
6.
Mainframe computers are very cheap.
Correct Answer
B. False
Explanation
The statement is false because mainframe computers are not cheap. Mainframe computers are large, powerful, and highly specialized machines that are designed to handle large-scale processing and storage tasks. They are typically used by large organizations and require significant investment in terms of hardware, software, maintenance, and operational costs. Therefore, they are generally expensive compared to other types of computers.
7.
Minicomputers have become outdated.
Correct Answer
A. True
Explanation
The statement "Minicomputers have become outdated" implies that minicomputers are no longer in use or relevant in the present time. This suggests that advancements in technology have made minicomputers obsolete or less popular compared to other computing devices. Therefore, the correct answer is "True" as it aligns with the given statement.
8.
Supercomputers are used extensively in the scientific field for research and simulations.
Correct Answer
A. True
Explanation
Supercomputers are indeed used extensively in the scientific field for research and simulations. These powerful machines are capable of processing massive amounts of data and performing complex calculations at incredibly high speeds. Scientists and researchers rely on supercomputers to model and simulate various scientific phenomena, such as weather patterns, climate change, molecular interactions, and astrophysical simulations. The use of supercomputers enables scientists to gain deeper insights into these phenomena and make advancements in various scientific disciplines. Therefore, the statement "Supercomputers are used extensively in the scientific field for research and simulations" is true.
9.
Personal computers are also called microcomputers.
Correct Answer
A. True
Explanation
Personal computers are commonly referred to as microcomputers because they are designed for individual use and are smaller in size compared to mainframe or minicomputers. The term "micro" in microcomputers signifies the use of microprocessors, which are the central processing units (CPUs) of these computers. Microcomputers are widely used by individuals for various purposes such as work, communication, entertainment, and personal tasks. Therefore, the statement that personal computers are also called microcomputers is true.
10.
A laptop is an example of a personal computer.
Correct Answer
A. True
Explanation
A laptop is considered a personal computer because it is designed for individual use and can perform similar functions as a desktop computer. It has a built-in keyboard, display screen, and trackpad or mouse, allowing users to complete tasks such as browsing the internet, creating documents, and running various software applications. Laptops are portable and can be easily carried around, making them convenient for personal use in different locations. Therefore, it is accurate to say that a laptop is an example of a personal computer.
