Hardware Components

Question: What is the primary function of the CPU?
Answer: The CPU (Central Processing Unit) is the “brain” of the computer. Its primary function is to execute instructions from software and hardware. It performs arithmetic, logical, control, and input/output (I/O) operations.
Question: What is RAM, and why is it important?
Answer: RAM (Random Access Memory) is a type of computer memory that stores data and program code that the CPU needs to access quickly. It is important because it allows the computer to run multiple programs and access data quickly. Without sufficient RAM, the computer will run slowly. It is volatile, meaning data is lost when the power is turned off.
Question: What is the difference between a hard drive (HDD) and a solid-state drive (SSD)?
Answer: A hard drive (HDD) is a traditional storage device that uses spinning platters and a read/write head to store data. A solid-state drive (SSD) uses flash memory to store data. SSDs are generally faster, more durable, and more energy-efficient than HDDs, but they are often more expensive per gigabyte. HDDs are suitable for large storage at a lower cost while SSDs are better for speed and responsiveness.
Question: Name three common input devices.
Answer:
- Keyboard
- Mouse
- Microphone
Question: Name three common output devices.
Answer:
- Monitor
- Printer
- Speakers

Software and Operating Systems

Question: What is an operating system (OS)? Give two examples.
Answer: An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. It acts as an interface between the user and the hardware. Examples include:
- Windows
- macOS
Question: What is the difference between system software and application software?
Answer: System software manages the computer hardware and provides a platform for application software to run. Application software is designed to perform specific tasks for the user, such as word processing, web browsing, or playing games. System software includes operating systems and utility programs, while application software includes programs like Microsoft Word, Google Chrome, and Adobe Photoshop.
Question: What is a web browser? Give two examples.
Answer: A web browser is an application software program that allows users to access and view websites on the Internet. Examples include:
- Google Chrome
- Mozilla Firefox

Basic Computer Operations

Question: What is a file extension? Give two examples.
Answer: A file extension is a suffix added to a file name, usually separated by a dot (.), that indicates the file type or format. Examples include:
- .docx (Microsoft Word document)
- .jpg (JPEG image file)
Question: How do you create a new folder on your computer?
Answer: The process varies slightly depending on the operating system, but generally, you can right-click in a blank area of a window (like your desktop or within another folder), select “New” from the context menu, and then choose “Folder.” Then you can type a name for the new folder and press Enter.
Question: What is the purpose of the “Ctrl + C” and “Ctrl + V” keyboard shortcuts?
Answer:
- Ctrl + C is used to copy selected text or files.
- Ctrl + V is used to paste the copied text or files.
