Q & A

What is the role of the CPU in a computer system?

The CPU (Central Processing Unit) is the brain of the computer. It processes all instructions, including mathematical calculations, data management, and deciding the sequence of tasks.

What is the function of the Arithmetic Logic Unit (ALU) in the CPU?

The ALU performs mathematical operations and logical decisions (like true or false). It is responsible for handling the computational tasks within the CPU.

How does the Control Unit work in the CPU?

The Control Unit manages the flow of data and instructions within the CPU. It decides which task should be executed first and directs data to the appropriate parts of the system.

What is the role of registers in the CPU?

Registers store temporary data that is actively being processed by the CPU. They ensure efficient data handling and prevent slowdowns during computation.

What is the difference between a CPU and a GPU?

The CPU handles general processing tasks, while the GPU (Graphics Processing Unit) specializes in rendering images, videos, and animations. The GPU works in parallel, completing tasks faster, especially in graphics-heavy applications like gaming and video editing.

null

RAM (Random Access Memory) temporarily stores data that is being actively used by applications or games. It allows for faster access compared to reading from a hard drive, making multitasking smoother.

What is the purpose of ROM in a computer?

ROM (Read-Only Memory) stores permanent instructions necessary for booting the computer, such as BIOS or UEFI. It retains data even when the computer is turned off.

How does cache memory enhance CPU performance?

Cache memory is a small but extremely fast storage unit attached directly to the CPU. It stores frequently accessed data and instructions, allowing the CPU to access them quickly, speeding up performance.

What is the difference between HDD and SSD in terms of performance?

HDD (Hard Disk Drive) uses mechanical parts and spinning disks for storage, which makes it slower in accessing data. SSD (Solid-State Drive) uses flash memory, offering faster, quieter, and more durable data access.

What is the role of input devices in a computer?

Input devices, like keyboards, mice, and microphones, allow users to interact with the computer by entering data and giving commands. They act as the communication bridge between the user and the machine.

What are output devices and why are they important?

Output devices, such as monitors, printers, and speakers, provide the results or responses from the computer to the user. They allow users to see, hear, or print the processed information.

How does the power supply function in a computer?

The power supply converts electricity from an outlet into a safe, usable form of power for the computer's components, ensuring they operate with the correct voltage and current.

What is the role of the motherboard in a computer?

The motherboard connects all the computer's components. It houses the CPU, RAM, GPU, storage devices, and provides the pathways for data to travel between them, enabling the system to function as a whole.
