Thermal printers are widely used in ATMs and POS systems. Why are they preferred over impact printers in these contexts?
Requires ink cartridges
Quiet, fast printing without mechanical impact
Slower printing speeds
Can print in color
GPU acceleration is commonly used in AI computations. What role does GPU play in this scenario?
Replaces RAM
Stores large datasets
Performs parallel processing on matrices faster than CPU
Runs the OS
EEPROM is a type of non-volatile memory used in embedded systems. What feature differentiates it from standard ROM?
Requires constant power
Can be electrically erased and reprogrammed multiple times
Only stores audio data
Faster than RAM
Multi-function printers combine several capabilities. Why might a business prefer an MFP over separate devices?
Uses less electricity than an LED
Always portable
Cheaper than paper
Consolidates printing, scanning, copying, and faxing in one device
