This act is considered illegal and a violation of copyright laws.

Tower, desktop, and CPU are all components of a computer. A tower refers to the case that houses all the hardware components of a desktop computer, including the CPU. The desktop is the entire computer system, which includes the tower, monitor, keyboard, and mouse. The CPU, or central processing unit, is the main component responsible for executing instructions and performing calculations in a computer. Therefore, it is correct to say that tower, desktop, and CPU are all the same components of a computer.

A keyboard is actually an input device, not an output device. It allows the user to input data, commands, and instructions into a computer or device. Output devices, on the other hand, are used to display or present information to the user, such as monitors, printers, and speakers.

The left button on a standard mouse is the most frequently used button in any usual operations of the computer. This is because the left button is typically used for selecting, clicking, dragging, and interacting with various elements on the computer screen. It is the primary button that allows users to perform actions such as opening files, navigating through menus, and interacting with applications.

The correct answer is "Mouse" because a mouse is a peripheral device that has a pointer, which is used to navigate and instruct the computer what to do. The mouse allows the user to move the cursor on the screen and select or interact with various elements or applications. The other options listed (Mice, Cursor, Arrow) do not accurately describe the device with a pointer.

The term "information" refers to processed data that has been organized in a meaningful way. While data is raw and unprocessed, information is the result of analyzing and interpreting that data. It is the knowledge or insights gained from the data. Therefore, "information" is the correct answer as it accurately describes the processed form of data.

The correct answer is Keyboard, Mouse, Scanner. These three devices are commonly used as input devices for computers. The keyboard allows users to input text and commands, the mouse enables users to navigate and interact with graphical user interfaces, and the scanner is used to convert physical documents or images into digital format.

A monitor is not an input device, but rather an output device. It is used to display information from the computer or other devices. Input devices, on the other hand, are used to input data or commands into the computer, such as a keyboard or mouse.

The term "hardware" refers to the physical components of a computer system, including the screen, keyboard, and storage devices. It encompasses all tangible parts that can be seen and touched. Output devices, such as screens, are a part of hardware, but they alone do not encompass the entire computer system. Input devices, such as keyboards, are also a part of hardware. Software, on the other hand, refers to the programs and instructions that run on the computer system, but it is not considered as part of the physical equipment. Therefore, the correct answer is hardware.

A scanner is not an output device because its main function is to input or scan physical documents or images into a digital format.
