After the execution of a standard near return instruction 'RET', what modification occurs to the Stack Pointer (SP) register?
Ch 10: Hardware Interrupts and PIC 8259
Examines hardware interrupt architecture, masking interrupts via IMR (port 0x21), cascading master and slave PICs, sending non-specific EOI (0x20) commands, and servicing asynchronous peripheral requests.

In order to convert a numerical single-digit value (0–9) into its corresponding ASCII character representation, which operation is performed?
Executing the assembly instruction 'MOV WORD [ES:160], 0x1230' writes a character '0' to text-mode Video RAM at which screen location?
In the 8-bit text-mode Video RAM attribute byte, which bit position controls the Red component of the background color?
In the 8-bit text-mode Video RAM attribute byte, which bit position controls the Blue component of the foreground text color?
In x86 assembly video routines, the clear screen operation initializes the entire text Video RAM block by writing which 16-bit word value?
How many traditional procedure parameter passing calling conventions (C and Pascal) exist in standard assembly integration?
When executing a far return instruction 'RETF', which register receives the offset component popped off the stack first?
After the execution of the instruction 'RET 2' (near return with 2-byte parameter cleanup), what is the total change to the Stack Pointer (SP) register?
