What is the difference between system software and application software?
Answer: System software manages hardware resources; application software performs user tasks
System software (like operating systems and utilities) manages computer hardware and provides a platform for running applications. Application software (like word processors and browsers) is designed to help users perform specific tasks.
Which unit is commonly used to measure CPU processing speed?
Answer: Gigahertz (GHz)
CPU clock speed is measured in gigahertz (GHz), which indicates how many billions of cycles per second the processor can execute.
What is cloud computing?
Answer: Delivering computing services over the internet on demand
Cloud computing delivers computing resources such as storage, processing power, and applications over the internet, allowing users to access them on demand without owning physical infrastructure.
What type of port is commonly used to connect external displays to a computer?
Answer: HDMI
HDMI (High-Definition Multimedia Interface) is a standard port used to transmit both high-definition video and audio signals from a computer to an external display.
What is multitasking in the context of operating systems?
Answer: The ability to run multiple programs or processes concurrently
Multitasking allows an operating system to run multiple programs or processes at the same time by rapidly switching between them or distributing work across processor cores.
What is the function of a motherboard in a computer?
Answer: It serves as the main circuit board connecting all components
The motherboard is the main printed circuit board that connects and allows communication between all major components including the CPU, RAM, storage devices, and expansion cards.
