What is the primary function of RAM (Random Access Memory) in a computer?
Answer: To temporarily hold data and instructions that the CPU is actively using
RAM is volatile memory that temporarily stores data and program instructions the CPU needs right now. Unlike a hard drive, RAM loses its contents when power is removed, which is why unsaved work disappears during a power outage.
What does a device driver do?
Answer: Acts as a translator between the operating system and a hardware device
A device driver is software that allows the operating system to communicate with specific hardware. Without the correct driver, the OS cannot send or receive data from a device like a printer or graphics card.
What is the role of the CPU (Central Processing Unit) in a computer?
Answer: To execute instructions and perform calculations for all running programs
The CPU is the brain of the computer — it fetches, decodes, and executes instructions from software. Every calculation, logic operation, and data movement passes through the CPU.
Which of the following best describes open-source software?
Answer: Software whose source code is publicly available and can be modified and distributed by anyone
Open-source software makes its underlying source code publicly accessible, allowing developers to inspect, modify, and redistribute it. Examples include Linux and LibreOffice, in contrast to proprietary software like Microsoft Windows.
What is the purpose of a computer's BIOS or UEFI?
Answer: To initialize hardware components and load the operating system when the computer starts
BIOS (Basic Input/Output System) and its modern replacement UEFI run the moment you power on a computer. They perform a POST (Power-On Self-Test) to check hardware, then locate and hand off control to the operating system bootloader.
What is the difference between application software and system software?
Answer: System software manages hardware and provides core services, while application software performs specific user tasks
System software (such as an operating system) forms the foundation that manages hardware resources and enables other programs to run. Application software (such as a word processor or web browser) sits on top of system software to fulfill end-user needs.
