What are the Critical Components of a Computer?
The critical hardware devices that comprise a computer architecture model are the output unit, the CPU, the cache, BUS Interface Unit, and the main memory. Importantly, all these devices are connected to one another through the I/O (local) bus, peripheral I/O Interface control unit, and system bus.
What Connects the Internal Hardware Components?
As such, every hardware
component, such as the secondary memory ((like USD Drive, Hard Drive, Optical
Drive), video monitor, keyboard, communication network, or any input-output
devices, are connected to an individual and localized control. With every hardware
component connected to a localized control through an IO bus, in turn, to the
peripheral I/O Interface control unit, and system Bus, The System connects to
the main memory and the CPU through the Bus Interface unit and the cache. Due
to the systematic interconnection of all the devices, an entire communication
system is made possible, enabling data flow.
What is the Data Flow Sequence from the Keyboard to the Monitor?
So, once the data enters the keyboard, the first thing is that the data will be flushed and become part of the main memory. The data reaches the CPU from the main memory using the BUS interface unit. Then, the CPU, the central processing unit, will process the data. And the processed information will be returned with the system BUS to the respective output device. So, this is what the hardware units inside the basic computer architecture model look like.
