What does the term 'Memory Footprint' refer to in software and systems administration?
A. The physical dimensions of a RAM chip.
B. The amount of carbon emission produced during memory manufacturing.
C. The total amount of main memory (RAM) a program consumes while running.
D. The historical layout of old memory tracks on a legacy drive.
Answer: Option C
Solution (By JKSSB Mock Tests)
The memory footprint represents the quantity of physical or virtual memory runtime space an active application requires or occupies while executing operations.
What is the name of the high-speed data transfer mechanism that allows specific hardware subsystems to access main system memory independently of the central processing unit?
Explanation:
DMA (Direct Memory Access) allows peripherals like network cards or graphics adapters to read/write directly to system RAM without routing the data through the CPU, reducing processor overhead.
Explanation:
The POST (Power-On Self-Test) routine is hardcoded into the system BIOS/UEFI ROM and runs instantly at startup to verify that essential hardware components are operational.
