QUESTION 1
Which of the following storage devices has the FASTEST read/write speeds?
A) Hard Disk Drive (HDD)
B) Solid State Drive (SSD)
C) Magnetic Tape
D) Optical Media (CD/DVD)
E) Floppy Disk
CORRECT ANSWER: B) Solid State Drive (SSD)
EXPERT RATIONALE: SSDs use flash memory technology with no moving parts,
allowing for read/write speeds ranging from 500 MB/s to over 7000 MB/s
depending on the interface (SATA, NVMe). HDDs rely on mechanical spinning
platters and read/write heads, limiting their speeds to approximately 100-200 MB/s.
Magnetic tape, optical media, and floppy disks are significantly slower storage
technologies.
,QUESTION 2
What is the maximum length of a standard Cat6 Ethernet cable before signal
degradation occurs?
A) 50 meters
B) 75 meters
C) 100 meters
D) 150 meters
E) 200 meters
CORRECT ANSWER: C) 100 meters
EXPERT RATIONALE: Cat6 cables are rated for a maximum distance of 100 meters
(approximately 328 feet) at frequencies up to 250 MHz. Beyond 100 meters, signal
degradation and attenuation become problematic, requiring the use of network
repeaters or switches to extend the network. This distance limitation applies to the
cable run from the network device to the patch panel or wall jack.
QUESTION 3
Which processor socket is commonly used for Intel's 12th generation (Alder
Lake) processors?
A) LGA 1155
B) LGA 1200
C) LGA 1700
D) LGA 2066
E) AM4
CORRECT ANSWER: C) LGA 1700
EXPERT RATIONALE: Intel's 12th generation Alder Lake processors, such as the
Core i9-12900K and Core i5-12600K, use the LGA 1700 socket. This socket
,introduction represented a significant change in Intel's processor packaging. LGA
1200 was used for 10th and 11th generation processors, while AM4 is AMD's
socket, and LGA 2066 is used for high-end Xeon processors.
QUESTION 4
What is the primary purpose of RAM caching in modern processors?
A) To store permanent data
B) To reduce latency by storing frequently accessed data closer to the CPU
C) To replace the role of virtual memory
D) To increase storage capacity
E) To manage network traffic
CORRECT ANSWER: B) To reduce latency by storing frequently accessed
data closer to the CPU
EXPERT RATIONALE: CPU cache (L1, L2, L3) stores frequently accessed instructions
and data in fast memory located on or very close to the processor. This
dramatically reduces latency compared to accessing data from main RAM or
storage. Cache operates on the principle that accessing data from cache is
significantly faster than accessing the same data from main memory, improving
overall system performance and CPU efficiency.
QUESTION 5
Which type of printer uses heat to fuse toner powder onto paper?
A) Dot Matrix Printer
B) Inkjet Printer
C) Thermal Printer
D) Laser Printer
, E) Impact Printer
CORRECT ANSWER: D) Laser Printer
EXPERT RATIONALE: Laser printers use a heated fusing unit to permanently bond
toner particles to paper. The process involves charging a photosensitive drum,
applying toner to charged areas, and then using a fuser assembly (typically heated
to 350-400°F) to melt the toner into the paper fibers. Thermal printers use heat to
activate special thermal paper, inkjet printers spray liquid ink, and dot
matrix/impact printers use mechanical strikes.
QUESTION 6
What does BIOS stand for?
A) Basic Input/Output System
B) Binary Integrated Operating System
C) Basic Instruction Operating Software
D) Bootable Input Output Settings
E) Basic Internet Output Service
CORRECT ANSWER: A) Basic Input/Output System
EXPERT RATIONALE: BIOS (Basic Input/Output System) is firmware that initializes
hardware during the boot process and provides runtime services for operating
systems and programs. It controls basic operations before the operating system
loads, including hardware configuration, boot sequence, and system settings. BIOS
has largely been replaced by UEFI (Unified Extensible Firmware Interface) in
modern systems, but both serve the same fundamental purpose.
QUESTION 7
Which of the following is the CORRECT order of the OSI model layers from
bottom to top?
