In the first part of my articles about basic architecture of computer, I had explained to you about 4 main basic components that took responsibility to support the computer’s operation that transform data become usable information.
Now, in this second part article, I will try to explain how the data flow among these components until it being transformed to become the usable information. In other words, I will try to explain how computer transform data into usable information.
How Computer Transform Data Into Usable Information
- Based on the above picture, let say you type the words SAYA in your word processing program using your keyboard (input device).
- The data S, A, Y and A will flow to the RAM (primary memory). It will be kept in there temporarily. At this stage, if you powered off your computer, the data will disappear.
- The processor will fetch (take) the data from RAM (primary memory). Then it will decode and execute the data to be usable information. In this case, the information is SAYA.
- The information will be sent back to RAM (primary memory) and then will be displayed on your monitor or will be printed using printer (output devices) based on your needs.
- If you save the information (the words SAYA that you typed in your word processing program), it will be kept permanently in your hard disk (secondary memory). So, the information will not disappear even you powered off your computer.
