instructions to complete various tasks.
2️⃣ What are the Main Components of a Computer?
💡The main components include:
1.​ CPU (Processor): The brain of the computer
2.​ RAM (Memory): Temporary storage for quick access
3.​ Storage (HDD/SSD): Stores data permanently
4.​ Input Devices: Keyboard, mouse, scanner
5.​ Output Devices: Monitor, printer
3️⃣ What is an Operating System (OS)?
💡An Operating System (OS) is software that manages hardware and software resources,
enabling users to interact with a computer (e.g., Windows, macOS, Linux).
4️⃣ What is the Difference Between Hardware and Software?
💡Hardware refers to physical components (CPU, RAM, keyboard), while software includes
programs and applications that run on the computer.
5️⃣ What is the Function of RAM?
💡RAM (Random Access Memory) temporarily stores data that the CPU needs to process
tasks quickly, improving system performance.
6️⃣ What is the Difference Between SSD and HDD?
💡SSD (Solid State Drive) is faster, more durable, and energy-efficient than HDD (Hard Disk
Drive), which has moving parts and slower performance.
7️⃣ What is the Purpose of a Hard Drive?
💡A hard drive stores the operating system, software, and user data permanently.
8️⃣ What is Cloud Computing?
💡Cloud computing allows users to store and access data online instead of on a local device.
Examples include Google Drive, Dropbox, and OneDrive.
