There are 4 elements that make up a personal computer system: the user, software, hardware and the electricity all working together for the whole system. Each of these elements is essential to the system itself.
The user is the person's who perform the task using the computer system. The nature of the task depends upon the application program or software that is needed to perform the task. The software that the user used requires certain hardware components to function properly.
The hardwares of the personal computer system are made up of its equipment that are usually connected (the computer, monitor, printer and so on). It is defined as hardwares because you can physically touch these components. The programs are called softwares since their function can only be used when the computer is turn ON. Software is a set of coded instructions that the computer uses in order to carry out the user's tasks.
The user can only use the computer when it is turned ON. Without any electrical power to run through the personal computer system, it will not function. The ability of the personal computer system to control its components is through a series of on/off signals.
Here is how it works, when a user tries to type a document or a letter using his/her personal computer. The first thing the user do is to turn ON the power for the computer. Choosing a Word Processor software in order to write the document. The user uses the hardware such as the keyboard to write the content of the document; the typed document is then displayed onto the monitor screen. After the user finished writing his/her document. The user will use the software to instruct the printer to print the document. The software works together with the hardware components (the keyboard, monitor and printer) to accomplish the task that the user requested.
All of the four elements: the electrical power, hardware, software and the user work together to make up a personal computer system.
