NIMCET 2010 — Computer PYQ

The correct answer is: (d) Micro-computer

Explanation

A stored program machine is a computer that stores program instructions in electronic memory (RAM/ROM) alongside the data. This follows the Von Neumann Architecture.

• Micro-computer: This is a complete computer (like a PC or laptop) that contains a CPU, memory, and $I/O$ systems. It is designed to load various programs into its memory and execute them, making it a true stored program machine.

• Micro-processor: While it is the "brain," it is just a component. A microprocessor by itself does not have the built-in memory required to store a full program; it must be connected to external memory to function as part of a stored program system.

• Calculator: Standard calculators are generally hard-wired or pre-programmed to perform specific functions and do not typically allow users to store and execute arbitrary complex programs in the same way a computer does.

• Analog-computer: These use continuous physical phenomena (like electrical voltage) to model problems rather than storing instructions as digital data in memory.
