What Is Program Counter Stack Pointer? The Stack Pointer register will hold the address of the top location of the stack. And the program counter is a register always it will hold the address of the memory location from where the next instruction for execution will have to be fetched. What is the program counter

What Is Store Program Architecture? The basic architecture of almost every computer system ever made is based on the stored program architecture designed in 1945 design by the mathematician John Von Neumann. He described a computer architecture where data and instructions would be stored in memory. What is the purpose of the stored program concept?
What Is The Purpose Of HLT Instruction? In the x86 computer architecture, HLT (halt) is an assembly language instruction which halts the central processing unit (CPU) until the next external interrupt is fired. Interrupts are signals sent by hardware devices to the CPU alerting it that an event occurred to which it should react. What
