Further, it can even perform logical functions like the comparison of data. It does basic mathematical calculations like addition, subtraction, division, multiplication, etc. This part of the CPU performs arithmetic operations. The memory unit uses a set of pre-programmed instructions to further transmit this data to other parts of the CPU. This data will now remain here until other components of CPU process it. Once a user enters data using input devices, the computer system stores this data in its memory unit. Here, it has to rely on a component called the central processing unit. The CPU further uses these three elements: Management Information Systems and Accounting Information SystemĪfter receiving data and commands from users, a computer system now has to process it according to the instructions provided.Capabilities of Computer System and Limitations of Computer Systems.Evolution and Features of Computerised Accounting Systems.Meaning and Elements of Computer System.Browse more Topics under Application Of Computers In Accounting From smartphones to ATM machines, these input devices are becoming very popular these days. Users can simply touch these screens without using any other device to enter commands. Other examples include barcode readers, Magnetic Ink Character Readers (MICR), Optical Character Readers (OCR), etc.Īnother example of input devices is touch-screens. Similarly, even a mouse can be an input unit for entering directions and commands. Computers then use their CPU to process this data and produce output.įor example, a laptop’s keyboard is an input unit that enters numbers and characters. Data can be in the form of numbers, words, actions, commands, etc. The main function of input devices is to direct commands and data into computers. These components help users enter data and commands into a computer system.
Hence, we can even call them building blocks of a computer system. They must work in complete synergy because that will ensure smooth overall functioning. While there are other components as well, these three are primarily responsible for making a computer function. Components of a Computer SystemĮvery computer system has the following three basic components:
These components are responsible for making computers actually function.
Apart from these elements, a computer system comprises of three basic components. No computer can function in the absence of these elements. These include hardware, software, programmes, data and connectivity. Going by this definition, several electronic devices, from laptops to calculators, are computers.Ī computer comprises of some basic elements. 157 Changing the Parameter values.Computers, in simple words, are machines that perform a set of functions according to their users’ directions.
