[Q.6] In the 8085 microprocessor, what is the size of the Stack Pointer (SP) register?
The Stack Pointer is a 16-bit register holding memory addresses.
[Q.7] Which memory write policy updates both cache memory and main memory simultaneously?
Write-through updates both cache and main memory on every write.
[Q.8] The BCD (Binary Coded Decimal) representation of the decimal number 29 is:
2 = 0010, 9 = 1001 in 4-bit BCD.
[Q.9] Which DMA data transfer mode hands control back to the CPU after transferring a single byte?
Cycle stealing transfers one word/byte at a time by stealing a bus cycle.
[Q.10] In a 8086 microprocessor, the Bus Interface Unit (BIU) is primarily responsible for:
BIU fetches instructions and calculates 20-bit physical addresses.
