Computer Hardware: What Am I? Worksheet

Explanation
The correct answer is CPU. The CPU, or Central Processing Unit, is often referred to as the "brain" of the computer. It is responsible for executing instructions and performing calculations, making it the most important component of a computer system. The CPU is responsible for carrying out all the tasks necessary for the computer to function properly, including running applications, managing memory, and handling input and output operations. Without a CPU, a computer would not be able to perform any tasks or process any data.

Explanation
The motherboard is the correct answer because it holds the CPU and other essential circuits. The motherboard is the main circuit board of a computer and it provides a platform for all other components to connect and communicate with each other. It houses the CPU, which is the central processing unit responsible for executing instructions and performing calculations. Additionally, the motherboard also holds other essential circuits such as the BIOS (Basic Input/Output System) which initializes the hardware during startup, the power supply which provides electricity to the components, and various ports for connecting peripherals.

Explanation
The GPU (Graphics Processing Unit) is responsible for handling high resolution graphics that are displayed on the monitor. It is specifically designed to process and render images, videos, and other visual content. The CPU, BIOS, power supply, hard drive, modem, ROM, motherboard, RAM, and port do not have the primary function of handling graphics.

Explanation
The correct answer is "port" because ports are the physical connectors on a computer or electronic device that allow other hardware components, such as the keyboard or monitor, to be plugged in. Without ports, it would not be possible to connect these external devices to the computer.

Explanation
RAM stands for Random Access Memory, and it is a type of computer memory that is used for short-term storage of data that the CPU (Central Processing Unit) needs to access quickly. RAM helps the CPU by providing fast and temporary storage space for data and instructions that are currently being processed. Unlike the hard drive or ROM, RAM is volatile memory, meaning that its contents are lost when the computer is powered off. Therefore, RAM is essential for the smooth and efficient operation of the CPU.

Explanation
The correct answer is "hard drive" because the information in the computer is stored on magnetic cylinders within the hard drive. The hard drive is a non-volatile storage device that permanently stores data even when the computer is powered off. It is used to store the operating system, software applications, and user files. The hard drive provides long-term storage and retrieval of data, making it an essential component for storing and accessing information in a computer system.

Explanation
RAM stands for Random Access Memory, which is a type of computer memory that allows data to be stored and accessed quickly by the CPU. It is a volatile memory, meaning that its contents are lost when the computer is turned off. This explains the statement in the question that if the computer is turned off, the person forgets everything. RAM is responsible for temporarily storing data that the CPU needs to access quickly, such as running programs and open files. When the computer is turned off, the data in RAM is erased, and the person would need to access the information again.

Explanation
The correct answer is ROM. ROM stands for Read-Only Memory, which is a type of computer memory that stores permanent data that cannot be modified. In this context, waking up the computer and reminding it what to do suggests that the computer is retrieving instructions or data from ROM. This is because ROM contains the firmware or startup instructions that the computer needs to begin its operations when powered on.

Explanation
A network card is responsible for connecting computers and allowing them to communicate with each other over the internet. It is a hardware component that enables a computer to send and receive data over a network. Without a network card, computers would not be able to connect to the internet or communicate with other devices on the network.
