Explanation
The operating system is not a physical part of a computer. It is a software program that manages the computer's hardware and software resources and provides a user interface for interacting with the computer. The motherboard, central processing unit, and keyboard are all physical components of a computer that are necessary for its operation.

Explanation
Firmware is the correct answer because it refers to the software that is permanently programmed into a hardware device. It is specifically designed to control the functions and operations of the hardware it is coupled with. Unlike regular software, firmware remains in the hardware even when it is powered off and is responsible for booting up the device and providing essential functionality.

Explanation
Software drives the hardware to excite an instruction. Software refers to the programs and instructions that are written to be executed by a computer. These instructions are processed by the hardware components of the computer, such as the CPU, memory, and input/output devices. The software tells the hardware what tasks to perform and how to perform them, including exciting specific instructions. Therefore, software is responsible for driving the hardware to excite an instruction.

Explanation
Random access memory (RAM) stores code and data used by the central processing unit (CPU). RAM is a type of computer memory that allows data to be read from and written to by the CPU. It is volatile memory, meaning that its contents are lost when the power is turned off. The CPU uses RAM to temporarily store instructions and data that it needs to access quickly during program execution. Unlike read-only memory (ROM), which stores permanent data and instructions, RAM can be read from and written to, making it a crucial component for the CPU's operations.

Explanation
The video card is responsible for processing and generating computer graphics. It is a hardware component that is specifically designed to handle the complex calculations and rendering required for displaying images and videos on a computer screen. The video card has its own dedicated memory and processing unit, which allows it to efficiently handle the graphics-intensive tasks. It works in conjunction with the computer's CPU and software to create and display the visual elements on the screen.

Explanation
The correct answer is chipset. The chipset is a collection of integrated circuits that manages the flow of data between the CPU, memory, and peripherals. It includes the north bridge, which connects the CPU to high-speed components like the memory and video card, and the south bridge, which connects to lower-speed components like the hard drive and USB ports. The chipset plays a crucial role in the overall performance and functionality of the motherboard.

Explanation
Chipset supports hardware monitoring and fan control. A chipset is a collection of integrated circuits that are designed to work together and provide various functionalities for a computer system. One of the functionalities provided by the chipset is hardware monitoring, which allows the system to monitor the temperature, voltage, and other important parameters of various hardware components. Additionally, the chipset also supports fan control, allowing the system to adjust the speed of the fans based on the temperature readings, ensuring efficient cooling and preventing overheating.

Explanation
Read-only memory (ROM) makes bootstrapping possible. Bootstrapping is the process of starting up a computer system. ROM contains firmware that is permanently stored and cannot be modified. During the boot process, the computer's firmware is loaded from ROM, providing the necessary instructions for the system to initialize and start up. This allows the computer to perform basic functions and load the operating system from other storage devices. Random access memory (RAM) is volatile and temporary, not suitable for bootstrapping. Watch battery and video card are unrelated to the bootstrapping process.

Explanation
A braille embosser is not an output device because it is used to create tactile braille output for individuals who are visually impaired. It converts digital text into braille characters that can be felt by touch. Therefore, it is not a device that displays or produces visual or auditory output like a joystick, printer, or speaker.

Explanation
A Braille embosser is not an input device because it is used to produce Braille text on paper, rather than taking in information from a user or external source. Input devices are typically used to enter data or commands into a computer or electronic device, such as microphones for voice input, image scanners for scanning documents or images, and joysticks for controlling movement or input in video games or other applications.
