Explanation

A Realtime operating system (RTOS) is designed to respond immediately to external events.

It is used in systems like aircraft controls, medical devices, and industrial machines, where delays can be critical.

Explanation

A microprocessor is an electronic component that is used by a computer to do its work.

Central processing unit on a single integrated circuit chip containing millions of very small components including transistors, resistors, and diodes that work together.

Explanation

PROM stands for Programmable Read-Only Memory.

A programmable read-only memory (PROM) is a form of digital memory where the setting of each bit is locked by a fuse or anti-fuse.

It is one type of read-only memory .

Explanation

Sensor is a device which detects or measures a physical property and records, indicates, or otherwise responds to it.

Explanation

• A microcontroller at least consists of a processor as its CPU with RAM, ROM, I/O ports and timers.
• It may contain some additional peripherals like ADC, PWM, etc.

Explanation

Microcontrollers usually integrate all essential components but may not have a separate Memory Management Unit (MMU).

The MMU is often found in more complex systems, not typically in basic microcontrollers.
