Computer Operating System & Memory

The CPU, or Central Processing Unit, is often referred to as the "brains" of the computer because it is responsible for executing instructions and performing calculations. It is the primary component that carries out the majority of the computer's processing tasks, including running programs, managing data, and controlling the overall operation of the system. Without a CPU, a computer would not be able to function or perform any tasks. Therefore, the statement that the CPU is known as the "brains" of the computer is true.

A computer application refers to a program or set of programs that perform specific tasks or functions on a computer. This includes applications like word processors, web browsers, and video editing software. Therefore, the correct answer is software, as it encompasses all computer applications.

The statement is true because a hard drive is a storage device commonly used to store documents and software on a computer. It is a non-volatile memory device that permanently stores data even when the computer is turned off. Therefore, all your documents and software can be stored on the hard drive for easy access and retrieval.

The correct answer is monitor and printer. A monitor is an output device that displays visual information, while a printer is also an output device that produces physical copies of documents. Input devices, on the other hand, are used to input data into a computer system. The options mouse, webcam, microphone, and keyboard are all examples of input devices as they allow users to provide input to the computer.

No, One Kilobyte = 1,000 Bytes

The "paint" program is not part of the operating system. It is a standalone application that allows users to create and edit images. While it may come pre-installed on some operating systems, it is not an integral part of the operating system itself.

Opening the operating system from an icon is not possible. An icon represents an application or a file, not the operating system itself. The operating system is the underlying software that manages the computer's hardware and provides a platform for running applications. To access the operating system, you need to start or boot the computer, which involves powering it on and going through the startup process. Icons on the desktop or in the taskbar typically represent applications or shortcuts to specific files or folders, not the operating system.

RAM memory stands for Random Access Memory, which is a type of computer memory that is used to store data that is currently being used by the computer. It is a volatile memory, meaning that its contents are lost when the computer is powered off or restarted. The data that is stored in RAM memory is quickly accessible by the computer's processor, allowing for faster and more efficient data manipulation and execution of programs. Therefore, what you see on your monitor is stored in RAM memory.
