While running, programs are known as processes or jobs. The following illustration shows the relationship between the different software programs and the hardware.
Application programs are the top software layer. You can perform specific tasks with these programs, such as using a word processor for writing, a spreadsheet for accounting, or a computer-aided design program for drawing. The other two layers, device drivers and the operating system, play important support roles. Your system might run one application program at a time, or it might run many simultaneously. Device drivers are a set of highly specialized programs.
Device drivers help application programs and the operating system do their tasks. Though these components are capable of working independently, in order to make the computer system to give accurate outcomes, it is important for these components to function in harmony with one another.
There are many devices qualified as both input and output units for the computer systems. The input unit is the beginning of the computation process where the process completely involves the user interaction, as this component is responsible for capturing the input from the user so as to command or instruct the other components of the computer. This process gives a lead to the computer on what to work and lets the next component to decide on how to brew up the results for the given input.
There are multiple input devices available for performing this activity, and it depends on the type of input required for specific tasks. The following are some of the commonly used input devices for carrying out the activities of the input unit are,. The Central Processing Unit is commonly referred to as the CPU that is generally used for fetching the input data or instructions from the input units and converting the unprocessed input data into a machine-readable format, which makes it easy for the computer to carry out the processing activities.
The Output Unit, similar to the input unit, is designed only for the sole purpose of interacting with the user of the computer system. It is normally used to give the processed results to the user, based on the input provided by the user themselves. The devices that handle the output processing should be capable of delivering any type of data or a combination of data types on their display units, including text, numbers, images, audio, video, gifs, etc.
A baby using a computer is one cute example of humanware. Even after purchasing the freshest ingredients and the finest pots and pans, there will not be a good meal without a chef. Both hardware and software are complemented by the works of a human to produce a fully functional computer system. I am touched with your article. Perfectly done. I like the comparism, the arrnagement and everything involved in this article.
Nice article. I am not techy but your article was easy for me to follow. I particularly like the comparison in the end to kitchen utensils, recipes and chefs. Am glad, i have added to my knowledge in the field of "Elements of Computer system" by visiting the site Nice Excellent Job Please i would like to know the main component of a personal computer system, pls I need an answer now.
Thanks Cent and all that make their thoughts loud and clear. I am grateful the content herein is beneficial to the readers. I want to know Wow great stuff, really interesting how computers work. I'm 57 and my 11 year old grandson has been teaching me how to use them, but when he's not there i rely on stuff on the 'web. Thanks again for your helpful page, good to see someone is informing us old fokes on this new tech.
You make my day easy. Wow such a wonderful comprehensive, essential explanation on computer issues. Thanks you a lot for this excellent job Social Networking. Internet Culture. Internet Entertainment. Internet Security. Internet Browsers. Computer Repairs. Cell Phones.
