Before we start writing programs and performing other tasks, such as debugging, let's understand how the components are organized in the system with the help of the following diagram:
We can see clearly that every primary component in the system is connected using the System bus. Therefore, every communication that takes place between the CPU, Memory, and I/O devices is via the System bus.
The CPU is the central processing unit in the system, and it is indeed the most vital component in the system. So, let's see how things are organized in the CPU by understanding the following diagram:
The preceding diagram shows ...
