[Q.6] Which memory mapping technique allows a block of main memory to be loaded into ANY cache line?
In Fully Associative Mapping, any memory block can be placed into any line of cache.
[Q.7] What is the primary function of a DMA (Direct Memory Access) controller?
DMA permits peripherals to transfer data directly to/from memory, bypassing CPU involvement.
[Q.8] How many address lines are needed to address a memory size of 4 KB?
4 KB = 4 * 1024 bytes = 4096 bytes = $2^12$. Thus 12 address lines are required.
[Q.9] Which interrupt in 8085 Microprocessor is non-maskable?
TRAP is the highest priority non-maskable hardware interrupt in the 8085.
[Q.10] What is the main advantage of RISC (Reduced Instruction Set Computer) architecture over CISC?
RISC relies on simple, uniform-length instructions optimized for fast, single-cycle execution via pipelining.
