Computer Applications And Parts Quiz! Trivia

The purpose of a computer's hard drive is to store data such as pictures, music, and documents. It is a non-volatile storage device that allows users to save and retrieve their files. The hard drive provides a large storage capacity for users to store their personal and professional data. It is where all the files and programs are stored, allowing users to access and use them whenever needed.

The keyboard is considered an input device because it allows Jim to input data into the computer system. In this case, Jim is using the keyboard to type his research paper, which means he is entering text and commands into the computer. Input devices are used to send data and instructions to the computer for processing.

If Sara accidentally unplugs her mouse while typing her final English paper, she will still be able to perform all operations because the mouse is not a required input device. She can utilize keyboard commands to navigate and perform all necessary tasks on her computer, including plugging her mouse back in, restarting her computer, and retyping her entire paper. The absence of a mouse does not hinder her ability to use the computer effectively.

The CPU inside of a computer is compared to the human brain because both the CPU and the brain process instructions. The CPU is responsible for executing instructions and performing calculations in a computer, just like the brain processes information and controls the body's functions. Both the CPU and the brain are considered the central processing units in their respective systems.

The early computers that were developed starting with the ABC were primarily focused on performing calculations such as adding, subtracting, and multiplying. These computers were designed to automate and speed up the process of performing complex mathematical calculations. They were not lightweight, as they were large and bulky machines. They also did not have the capability to store large amounts of data for an extended time period. Additionally, they were not commonly found in most American homes, as they were primarily used in research institutions and government facilities.

RAM stands for Random Access Memory, and it is the component that is needed to allow more programs to be stored while they are open. RAM is responsible for temporarily holding data that the computer is actively using. When Tom opens a game or any other program, it gets loaded into RAM, allowing the computer to access and process the data quickly. If the computer has insufficient RAM, it may struggle to handle multiple programs at once, causing it to slow down and not perform well. Therefore, increasing the amount of RAM can help Tom play numerous games on his computer without experiencing performance issues.

Sam removed several components from his computer system and cleaned them before placing everything back. However, when he tried to power on his machine, he realized that no processing was occurring. Since the central processing unit (CPU) is responsible for executing instructions and performing calculations in a computer system, it can be inferred that Sam left out the CPU. Without the CPU, the computer cannot carry out any processing tasks, resulting in the observed lack of processing.

The author is referring to "run-of-river" hydrokinetic, which means using the natural flow of water to generate electricity. This method does not involve using steam, air, or turbines to manipulate the water, but rather harnesses the kinetic energy of the flowing water to turn a turbine and generate electricity.

The given features of the computer system - 19" flat panel monitor, 300gb Hard Drive, Canon Printer, and Intel processor - can be classified into the group of the four main components of a computer. These components typically include the monitor, storage device, input/output device, and the central processing unit (CPU).

The operations described in the question, such as typing on the keyboard, seeing the letters appear on the screen, and saving the work, all fall under the category of information processing. This cycle involves the manipulation and transformation of data or information. Typing on the keyboard is the input, seeing the letters on the screen is the output, and saving the work involves processing and storing the information. Therefore, the correct classification for these operations is information processing.

The passage discusses the importance of finding alternative power sources, specifically focusing on hydro-power. It explains how hydro-power can be a sustainable and environmentally friendly alternative to traditional power sources like fossil fuels. The article highlights the benefits of hydro-power, such as its renewable nature and ability to reduce greenhouse gas emissions. It also mentions various hydro-power projects and initiatives that are being implemented in the United States. Overall, the passage emphasizes the significance of exploring alternative power sources to reduce dependence on fossil fuels and mitigate environmental impacts.

The first paragraph of the article suggests that the United States utilizes hydroelectric power but is also looking for other options concerning the use of "water" power. This implies that while hydroelectric power is currently being used, there is a search for alternative methods of harnessing water power. The paragraph does not mention that the United States relies very heavily on hydroelectric dams or that it protects the environment by not allowing the creation of new dams. It also does not mention that the United States leads the world in the design of alternative power systems.

The Altair 8800 was the first personal computer sold to the public and was developed by MITS. It did not have a monitor, keyboard, or disk storage. This statement accurately identifies the particular computer system and its specific qualities.

The author of the article would be least likely to recommend installing numerous hydrokinetic power stations and recording results for later study and review. This is because the author does not mention anything about conducting experiments or studies in the article. Instead, the author focuses on the benefits and potential of hydrokinetic power as an alternative power source, emphasizing the need for examination and study of its cost-effectiveness and environmental friendliness. The author also mentions the use of green resources such as water and wind to generate power, which aligns with the recommendation to generate power using green resources.

The third paragraph of the article states that hydrokinetic power is "an unproven power source that has the potential to be more cost efficient than wind power." This suggests that while hydrokinetic power is not yet proven, it has the potential to be a more cost-effective alternative to wind power.
