Questions and Answers

1.

Which type of ROM can be erased by UV light?
- A.
  
  PROM
- B.
  
  EEPROM
- C.
  
  EPROM
- D.
  
  ROM
Correct Answer
C. EPROM

Explanation
EPROM stands for Erasable Programmable Read-Only Memory. It is a type of ROM that can be erased by exposing it to ultraviolet (UV) light. EPROM chips have a transparent window on the top that allows UV light to pass through. When the EPROM needs to be erased, the chip is taken out of the circuit and exposed to UV light for a specified amount of time. This erases the data stored in the EPROM, making it ready to be reprogrammed with new data.

Which technique enhances the CPUs performance by executing multiple peices of code simultaneously on each pipeline?
- A.
  
  CPU throttling
- B.
  
  Flashing the BIOS
- C.
  
  Hyperthreading
- D.
  
  CISC
Correct Answer
C. Hyperthreading

Explanation
Hyperthreading is a technique that enhances the CPU's performance by executing multiple pieces of code simultaneously on each pipeline. It allows the CPU to handle multiple threads or tasks at the same time, by creating virtual cores that share the resources of a physical core. This improves overall efficiency and can result in better performance, especially in situations where there are multiple threads or tasks running concurrently. CPU throttling, flashing the BIOS, and CISC are not related to the execution of multiple pieces of code simultaneously on each pipeline.

What print technology do laser printers use?
- A.
  
  Piezoelectric
- B.
  
  Electrophotographic
- C.
  
  Electrostatic spray
- D.
  
  Impact
Correct Answer
B. ElectropHotograpHic

Explanation
Laser printers use electrophotographic print technology. This technology involves a laser beam that scans the surface of a drum or a photosensitive belt, creating an electrostatic image. The drum or belt is then coated with toner, which is attracted to the charged areas on the surface. Finally, the toner is transferred onto the paper and fused using heat to create the printed image. This process allows for high-quality and precise printing, making electrophotographic technology ideal for laser printers.
