#1
What does RAM stand for in computer hardware?
Random Access Memory
ExplanationRAM stands for Random Access Memory, a type of computer memory that allows quick access to stored data.
#2
Which of the following storage devices is considered non-volatile?
SSD
ExplanationSSD, or Solid State Drive, is considered non-volatile storage as it retains data even when power is turned off.
#3
Which technology is used in modern Solid State Drives (SSDs) to store data?
NAND flash memory
ExplanationModern SSDs use NAND flash memory technology to store and retrieve data.
#4
What is the primary purpose of a heatsink in a computer?
To dissipate heat away from the CPU
ExplanationA heatsink in a computer is designed to dissipate heat away from the CPU, preventing overheating and ensuring stable operation.
#5
What distinguishes a mechanical hard drive (HDD) from a solid state drive (SSD)?
HDDs use magnetic storage, while SSDs use integrated circuits
ExplanationHDDs use magnetic storage, while SSDs utilize integrated circuits, differentiating their storage mechanisms.
#6
What is the primary function of a CPU?
Process instructions
ExplanationThe CPU, or Central Processing Unit, is the primary component that processes instructions and performs calculations in a computer.
#7
In computer architecture, what does the term 'pipelining' refer to?
A technique to increase CPU instruction throughput
ExplanationPipelining is a technique in computer architecture that enhances CPU instruction throughput by overlapping execution stages.
#8
What is the main advantage of using RAID 0 configuration?
Improved performance
ExplanationRAID 0 configuration provides improved performance by striping data across multiple drives, enhancing data access speed.
#9
What does the term 'clock speed' refer to in the context of CPU performance?
The frequency of the system clock
ExplanationClock speed in CPU performance refers to the frequency of the system clock, determining how quickly the CPU can process instructions.
#10
Which of the following interfaces is primarily used for connecting graphics cards to a motherboard?
PCI Express
ExplanationPCI Express is the primary interface for connecting graphics cards to a motherboard, facilitating high-speed data transfer.
#11
What distinguishes DDR4 RAM from DDR3 RAM?
Higher speed and lower voltage
ExplanationDDR4 RAM differs from DDR3 RAM with higher speed and lower voltage, improving overall performance and efficiency.
#12
In the context of data storage, what does 'IOPS' stand for?
Input/Output Operations per Second
Explanation'IOPS' stands for Input/Output Operations per Second, measuring the speed of data read and write operations in storage devices.
#13
What is ECC memory primarily used for?
Detecting and correcting errors in data
ExplanationECC (Error-Correcting Code) memory is used to detect and correct errors in data, enhancing system stability and reliability.
#14
In terms of computer graphics, what does the term 'ray tracing' refer to?
A rendering technique for generating an image by tracing the path of light
Explanation'Ray tracing' is a rendering technique in computer graphics that simulates the path of light to generate realistic images with enhanced lighting effects.
#15
What is the main difference between an M.2 SSD and a SATA SSD?
M.2 SSDs can use the NVMe protocol for faster data access
ExplanationThe main difference is that M.2 SSDs can use the NVMe (Non-Volatile Memory Express) protocol, allowing faster data access compared to SATA SSDs.
