Answer 2

The fundamental parts of a microcomputer are:

1) CPU

2) Software memory

3) Data storage

4)Output ports

5) Ports for input

6) Clock generator

• The CPU is made up of three parts: the Arithmetic and Logic Unit, the Register Unit, and the Control Unit. The CPU stores processed data in memory as well as stored commands and data words in storage.
• A microcomputer system's fundamental job is to make sure that its CPU correctly carries out the intended instruction sequence. The CPU begins by carrying out the instruction at a preset point in programme memory upon initialization, which is often a power up and manual reset.
• The microcomputer can interact with the external world thanks to the input and output ports.
• The input interface allows data to enter the system through the outside world, which is something the microcomputer will utilise to manipulate data before sending it to output devices.
• The microprocessor executes instructions within the proper clock periods that are generated by the clock generator. This requirement guarantees that events can develop in various paths of the systems in a methodical manner.
