Which type of ROM requires a specialized hardware device called a 'ROM programmer' or 'burner' to write data onto it for the first time?
A. Mask ROM
B. PROM
C. DRAM
D. SRAM
Answer: Option B
Solution (By JKSSB Mock Tests)
PROM (Programmable Read-Only Memory) chips are manufactured blank and require a dedicated hardware device called a PROM burner to permanently blow internal fuses, writing the data once.
Explanation:
Legacy IDE/PATA drive architectures required users to set small physical plastic blocks (jumpers) over pins to designate a drive as 'Master' or 'Slave' on a shared ribbon cable.
Explanation:
DRAM stores data using capacitors, which lose charge over time. This design requires continuous refreshing cycles, introducing latency that makes it slower than SRAM.
