What does CPU stand for?
Central Performance Unit
Central Power Unit
Computer Processing Unit
Central Processing Unit
The CPU, or Central Processing Unit, performs the core computations and operations in a computer by executing instructions from programs. It is often referred to as the 'brain' of the computer because it manages all processing tasks. Without the CPU, the computer could not run software or perform calculations. For more details, see this article.
Which device is used for pointing and clicking?
Printer
Mouse
Keyboard
Monitor
A mouse is an input device that allows users to point to objects on a screen and perform click actions. It typically features buttons and a scroll wheel to navigate and interact with graphical user interfaces. The mouse translates physical movement into pointer movement on the display. For more information, see this page.
Which component provides power to the PC?
Power Supply Unit (PSU)
Graphics Processing Unit (GPU)
CPU cooler
Hard Disk Drive (HDD)
The Power Supply Unit (PSU) converts AC power from the wall outlet into the DC power required by internal components. It distributes regulated voltage to the motherboard, drives, and peripheral devices. Without a PSU, a desktop computer cannot turn on or operate. Learn more at this resource.
What does HDD stand for?
Hard Drive Disk
High Definition Disk
Hard Disk Drive
Heavy Duty Drive
HDD stands for Hard Disk Drive, which stores data magnetically on spinning platters. It offers high storage capacity at a lower cost per gigabyte compared to SSDs but generally has slower read/write speeds. HDDs are commonly used for mass storage in desktops and servers. More details can be found at this page.
Which device is used to input text?
Speaker
Mouse
Keyboard
Scanner
A keyboard is an input device that lets you enter letters, numbers, and symbols into a computer by pressing keys. It is the primary tool for text entry in applications, documents, and command-line interfaces. Keyboards can be wired or wireless and come in various layouts. For a deeper look, visit this link.
What is the primary function of RAM in a desktop computer?
Provide long-term storage for files
Temporarily store data for quick access by the CPU
Process graphics and render images
Supply power to internal components
RAM (Random Access Memory) provides fast, volatile storage that the CPU uses to read and write data during active tasks. It allows quick access to programs and data, speeding up system operations. When the system powers off, RAM contents are lost, unlike long-term storage. See this resource for more.
Which interface is most commonly used to connect external storage devices?
USB
VGA
HDMI
PS/2
USB (Universal Serial Bus) is the standard interface for connecting a wide variety of external devices, including storage drives, keyboards, and printers. It supports hot-swapping and provides power to peripherals. USB ports come in different versions (e.g., USB 2.0, USB 3.0) that offer varying data transfer speeds. Learn more at this page.
What does GPU stand for?
Graphics Performance Utility
General Purpose Unit
Global Processing Unit
Graphics Processing Unit
A GPU, or Graphics Processing Unit, is specialized hardware for rendering images and video to a display. It offloads graphic-related computations from the CPU, improving performance in gaming, visualization, and compute-heavy applications. Modern GPUs also support parallel processing for scientific workloads. For details, see this article.
Which storage type is generally faster in data access times?
Hard Disk Drive (HDD)
Optical drive
Floppy disk
Solid State Drive (SSD)
SSDs use flash memory with no moving parts, resulting in much faster read/write speeds and lower latency compared to platter-based HDDs. They improve boot times and application loading significantly. HDDs remain useful for cost-effective large-capacity storage. Additional comparisons are available at this page.
What is the purpose of the motherboard's BIOS?
Initialize hardware and boot the operating system
Render graphics output
Regulate the power supply voltages
Store user documents
The BIOS (Basic Input/Output System) performs hardware initialization during the boot process and provides a runtime environment for the operating system. It runs a Power-On Self-Test (POST) to ensure components are functioning before handing control to a bootloader. Modern systems often use UEFI instead of traditional BIOS. Read more at this link.
Which bus speed setting primarily affects data transfer rates between the CPU and RAM?
Front Side Bus (FSB)
SATA speed
USB Bus speed
PCIe lane speed
The Front Side Bus (FSB) was historically the main communication channel between the CPU and system memory, determining how fast data could travel between them. Modern CPUs often use integrated memory controllers and point-to-point connections like Intel's QuickPath Interconnect. Understanding bus speeds remains crucial for compatibility and performance tuning. More at this article.
What port type on older PCs is typically color-coded purple?
HDMI port
USB port
PS/2 keyboard port
Ethernet port
On legacy motherboards, the PS/2 keyboard port is color-coded purple, while the mouse port is colored green. PS/2 connectors provide a serial communication interface for keyboards and mice. Although largely replaced by USB, PS/2 ports remain for certain compatibility uses. See this resource.
Which RAID level mirrors data across two drives for redundancy?
RAID 0
RAID 1
RAID 6
RAID 5
RAID 1 duplicates data identically on two or more drives to provide redundancy; if one drive fails, the data remains available on the other. RAID 0 stripes data without redundancy, improving performance but risking data loss if a drive fails. RAID 5 and 6 add parity for fault tolerance across multiple drives. More details at this page.
What is the main difference between USB 2.0 and USB 3.0?
Voltage standard
Connector shape
Power on/off behavior
Maximum data transfer speed
USB 3.0 (also known as USB 3.1 Gen 1) increases maximum data transfer rates up to 5 Gbps, compared to 480 Mbps for USB 2.0. USB 3.x ports are often color-coded blue to differentiate them. The voltage standard remains largely the same, but power delivery capabilities may differ in advanced USB versions. For more, see this article.
Which memory technology used in modern high-end GPUs stacks memory dies to achieve very high bandwidth?
GDDR6
DDR4
SDRAM
High Bandwidth Memory (HBM)
High Bandwidth Memory (HBM) stacks multiple DRAM dies vertically beside the GPU die, connected through an interposer, to deliver much higher bandwidth and lower power consumption compared to GDDR memory. It is used in high-performance graphics cards and compute accelerators. HBM2 and HBM2e improvements further increase capacity and speed. Read more at this page.
