Computer on a single chip is called

A computer on a single chip refers to a system that integrates the central processing unit (CPU), memory, and input/output interfaces into one integrated circuit. This is known as a microcontroller. A microprocessor, on the other hand, is only the CPU and requires external components to function as a computer. An assembler is a software program used to translate assembly language into machine code and is not a hardware device. Therefore, the correct term for a computer on a single chip is microcontroller.

Basically, a microprocessor is only the CPU and needs external memory and I/O devices to work, so it is not a complete system. In contrast, a microcontroller has CPU, memory, and I/O ports all integrated on a single chip, making it a complete computer. Hence, “computer on a single chip” refers to a microcontroller, not a microprocessor.
