Explanation

A complete microcomputer system includes a microprocessor (CPU), memory (RAM/ROM), and peripheral devices (keyboard, monitor, etc.).

All components work together to input, process, store, and output data.

Explanation

System software includes the operating system and core programs that manage hardware and software resources.

It helps the computer run smoothly and provides a platform for application software to operate.

Explanation

The OS (e.g., Windows, macOS, Linux) manages all hardware/software operations, including:

• Memory allocation.
• File management.
• Running applications (like MS Word).

Without identifying the actual problem, no effective solution can be planned or executed.

Explanation

The CPU (Central Processing Unit) includes:

1. ALU (Arithmetic Logic Unit)
2. CU (Control Unit)
3. Registers (temporary storage inside CPU)

Primary Storage (like RAM) is not part of the CPU; it is part of the main memory.

Explanation

In batch processing systems, all tasks are executed without user interaction, so incorrect or undesired commands may run unnoticed.

This can lead to errors or wasted resources, making it a key drawback of the system.
