In everyday life, you are often faced with gathering various types of information and processing. There’s no way you manage all the data in your brain, right? To assist in managing these tasks that cannot be done by the human brain, then a computer is created. In managing information in the form of data, computers need a system called a computer system. This system acts as a bridge between components on a computer. This article will discuss more deeply about the definition of computer systems, especially the functions of computer systems. Check out more below.
Computer systems are a set of components that are interconnected with one another, allowing these components to interact with each other to perform tasks that have been instructed by the user or brainware. In general, the components of a computer system are divided into three, namely Hardware, Software & Brainware. The three components each have different functions and roles according to their uses. Although different functions and roles, but all three must work hand in hand, if one of them does not function properly then the other components will also experience the same thing. For example: Computers will not work without instructions from a user or brainware, as well as a software will not mean anything without a hardware.
The computer system has 4 main functions, namely:
Computer systems function to input all types of data that have been entered by the user through hardware devices such as a mouse, keyboard, microphone and others. Applications that are used in computers will also determine how data is input. This can be done manually, automatically or a combination of both.
The next main function is processing data. Where data that has been inputted by the user is still raw. Therefore after inputting the system will do a process which transfers raw data into information that can be read by computer memory. This data process is carried out on the Central Processing Unit (CPU) which also acts as the computer brain. It is important to note that processing units of modern personal computing devices continue to evolve and outperform their predecessors. One particular area is the incorporation of the CPU and graphics processing unit (GPU) into what is now known as an accelerated processing unit (APU). Merging enables new processors to integrate powerful graphics processing capabilities over traditional arithmetic and logical calculations. After the data is processed to information, it can be stored or displayed according to the user’s needs.
Computer systems function to produce an output which is the result of data that has been processed. The output can be in the form of information, images, sound or video.
The last and most important function of a computer system is the storage of data and information. Storage integrity is an important stage that can really determine the value of a computer system. In each case, what is the use of a computer without data or information? The computer system functions to store output data which is the processed product of the process in computer memory. Computers can store internal and external information. The hard disk drive (HDD) and / or solid state disk (SSD) drive is internal device storage and serves to protect all data and information on the computer. Whereas, external storage is achieved through accessories that attach externally to the computer. They include external and optical drives.
This is the main function of a computer system that is contained in your computers. Hopefully this info is useful to you.
