Computer Basics
What does the term "bit" represent in computing?
Binary digit
What device is used to move the cursor on the screen?
Mouse
What component inside the system unit generates heat and requires cooling?
CPU
What is the purpose of cache memory?
To speed up data access for the CPU.
What are the main types of output devices?
Monitors, printers, and speakers.
What technology allows computers to communicate over the internet?
Networking
What does LAN stand for?
Local Area Network.
What is the role of the chipset on a motherboard?
To manage data flow between components.
What slots are used to add expansion cards to a motherboard?
PCIe slots
What is the primary function of an input device?
To allow users to enter data and commands into a computer.
What is the function of RAM in a computer?
To provide temporary memory for active processes.
What is the purpose of an operating system?
To manage hardware and software resources
What does a power supply unit (PSU) do?
Converts AC to DC power.
What is the standard voltage supplied by a PSU to most computer components?
12 volts
How do touchscreens differ from traditional input devices like keyboards and mice?
Touchscreens allow direct interaction with the display, enabling gesture-based commands instead of relying on separate hardware.
How does the BIOS differ from the operating system in a personal computer?
BIOS initializes hardware at startup, while the operating system manages software and user interactions
What role does a router play in a local area network (LAN)?
A router connects different networks and directs data packets between them.
What are the key components typically housed within the system unit?
CPU, RAM, motherboard, power supply, and storage drives.
How does increasing RAM in a computer system affect multitasking capabilities?
More RAM allows for more applications to run simultaneously without slowing down the system.
How does resolution affect the quality of output on a monitor?
Higher resolution provides more pixels, resulting in sharper and clearer images.
What is the purpose of a bus in a computer system?
To facilitate communication between the CPU, memory, and other components.
What are the differences between a desktop computer and a laptop regarding hardware configuration and power management?
Desktops typically have more powerful hardware and require a constant power source, while laptops are designed for portability and use batteries.
What is the difference between primary memory and secondary memory in terms of speed and usage?
Primary memory (RAM) is fast and temporary, used for active processes, while secondary memory (HDD/SSD) is slower but provides permanent storage.
How does increasing RAM in a computer system affect multitasking capabilities?
More RAM allows for more applications to run simultaneously without slowing down the system.
What is the difference between SSDs and HDDs in terms of data access speed and reliability?
SSDs are faster and more reliable because they have no moving parts, while HDDs are slower and more prone to mechanical failure.
