Stack Organization 19 Jul,2023 boomtecho2@gmail.comLeave a comment Please enter your email: 1. The Stack follows the sequence first-in-first out Last-in-last out first-in-last-out last-in-first out 2. A stack organized computer uses instruction of Indirect instruction two addressing zero addressing Index addressing 3. A stack is _ an 8 bit register in the microprocessor an 16 bit register in the microprocessor A set of memory location in R/WM reserved for storing information temporarily during the execution of computer 16 bit memory address stored in the program counter 4. A stack pointer is _ A 16 bit register in the microprocessor that indicate the beginning of the stack memory a register that decodes and executes 16 bits arithmetic expression the first memory location where a subroutine address is stored a register in which flags bits are stored 5. In stack organization the insertion operation is known as ____________: POP push both none 6. In stack organization the deletion operation is known as ____________ pop push both A and B none 7. A stack in a digital computer is a part of the ____________: ALU CPU Memory unit none of the above 8. In stack organization address register is known as the: memory stack stack pointer pop operation push operation 9. The stack is useful for storing the register status of the processor temporary storage of data storing contents of registers temporarily inside the CPU All of the Above 10. The Stack is accessed using Sp register ss register sp and ss register none of the above 11. As the storing of data words onto the stack is increased, the stack pointer is increment by 1 increment by 2 decrement by 1 decrement by 2 12. While retrieving data from the stack, the stack pointer is incremented by 1 decremented by 2 incremented by 2 decremented by 1 13. The process of storing the data in the stack is called ……… the stack. pulling into pulling out pushing into pushing out 14. In register stack a stack can be organized by a ____________ number of register: infinite number finite number both A and B none of the above 15. Which operation are done by increment or decrement the stack pointer: Pop Push both A and B none 16. In register stack a stack can be a finite number of: control word memory word transfer word All of the above 17. The stack based CPU organization _ Efficient computation of complex Arithmetic expression Execution of instructions is fast the length of instruction is short All of the above 18. The stack pointer contains the address of the word that is currently on ____________: top of stack down of stack top and down both none of the above 19. In register stack items are removed from the stack by using the ____________ operation: pop push pop and push both none of the above 20. Which register holds the item that is to be written into the stack or read out of the stack: SR IR RR DR 21. The operation is specified by a binary code known as the ____________: operand code opcode source code All of the above Loading …
