Addressing mode calculation determines the effective address.

Mode field bits are part of the instruction format

Instruction format defines the layout of bits of an instruction

Variable-length instructions reduce processor complexity.

Variable-length instructions provide efficient and compact variations.

Stack is a reserved block of memory locations

Index addressing is mainly used for recursive procedures

Index addressing is efficient for iterative operations.

Time complexity of Push operation is:

In postfix expression, operator comes:

Postfix form of (A + B) is:

Postfix of (A + B) * C is:

Evaluate postfix: 3 4 + 2 *

In infix expression, operator is:

Which operation removes element from queue?

Queue follows which principle?

In linear queue, insertion happens at:
