Parts & Functions Of Computer | Input, Process, Storage & Output


What makes a computer a computer? Is it necessary to have a few pieces to consider a computer a computer? Consider computers of the 1980s: they all consisted of a display screen, a keyboard, and a processing unit. Over time, computers have evolved into devices that do not look like "typical" computers. Consider an iPhone or Android tablet, where the method of input depends on touch, without the use of a separate keyboard.

Regardless of the machine's form factor, four basic functions - input, output, storage, and processing - make up a computer. Below is a demonstration of how those tasks work together.

Therefore, as we consider the history of computers and the future of computers, we must consider what is a computer and what is not. Obviously, we have desktop and laptop computers, as they perform input, processing, output and storage functions. But also because we have cellular phones and smartphones because they perform all these functions. What about our television? Many of these are also complex computers, as they take information from our inputs using a remote control, process the information, and return the output, such as an on-demand movie. Many of these televisions store information, such as your favourite channels or even video content for later playback. Some thermostats are even computers, as they perform these functions, such as "smart thermostats", such as NEST and other popular brands. Remember, the main determinant of something is the computer or not it depends on what works: does it do input, processing, output and storage? If so, it is a computer.
