A computer requires a power supply unit (PSU) in order to function. The PSU is responsible for converting the alternating current (AC) from the electrical outlet into direct current (DC) that the computer components can utilize. It supplies power to the motherboard, CPU, graphics card, and other hardware components. Without a PSU, the computer would not receive the necessary power to operate. Therefore, the statement "True" is correct.

RAM stands for Random Access Memory. It is a type of computer memory that allows data to be read from and written to in any order, regardless of the physical location of the data. This means that the computer can quickly access and retrieve data from RAM, making it an essential component for the smooth functioning of a computer system.

The given answer accurately defines a storage device as a hardware capable of holding information. This means that a storage device is a physical device that can store data, such as files, documents, or media. It provides the option to record and store information, allowing users to save and retrieve data as needed. Examples of storage devices include hard drives, solid-state drives, USB flash drives, and memory cards.

The correct answer is Power Supply Unit. PSU stands for Power Supply Unit, which is a hardware component that provides electrical power to a computer or other electronic devices. It converts the AC power from the wall outlet into DC power that is suitable for the computer's internal components. This is an essential component for the proper functioning of a computer system.

A keyboard is considered an input device because it allows the user to input data or commands into a computer or other electronic device. The user can type letters, numbers, and other characters on the keyboard, which are then processed and displayed on the screen or used to control the device. Therefore, the keyboard facilitates the input of information rather than producing an output.

The correct answer is "Central Processing Unit." The CPU is the main component of a computer that performs most of the processing inside the computer. It interprets and executes instructions from the computer's memory, performs arithmetic and logical operations, and controls the input and output of data.

A touchscreen can be considered both an input and output device because it allows users to interact with the device by touching the screen, which is an input action. It also displays information and visuals on the screen, which is an output action. Therefore, a touchscreen serves the purpose of both input and output, making the statement true.

The microphone and mouse are both examples of input devices. A microphone is used to input sound or voice into a computer or other electronic device. It allows the user to record audio or communicate through voice input. On the other hand, a mouse is an input device that allows the user to control the cursor and interact with the computer by clicking, dragging, and selecting items on the screen. Both of these devices provide input to the computer system, making them input devices.

Excel and Microsoft Access are both examples of application software. Application software refers to programs that are designed to perform specific tasks or functions for users. Excel is a spreadsheet program that allows users to create, edit, and analyze data in a tabular format. Microsoft Access is a database management system that allows users to store, organize, and retrieve data. Both of these software applications are widely used in various industries and are considered essential tools for data management and analysis.

If you didn't have a video card, you would not be able to see pictures on your computer. A video card is responsible for rendering and displaying images, videos, and graphics on your monitor. Without a video card, your computer would not be able to process and output visual information, making it impossible for you to see pictures or any visual content on your screen.

A kettle is a simple appliance used for heating water and does not require complex functions or calculations that would necessitate the use of a microprocessor. It typically consists of a heating element, a switch, and a thermostat to control the temperature. Therefore, it is unlikely to have a microprocessor inside it.

A microprocessor is a component that needs instructions. It is a small electronic device that functions as the central processing unit (CPU) of a computer. It is responsible for executing instructions and performing calculations, making it an essential component in any computer system. Without instructions, a microprocessor would be unable to carry out any tasks or functions. Therefore, it is accurate to describe a microprocessor as a component that needs instructions.
