Four Essential Elements of Computer System

          In these 4 Essential Elements of Computer System this would be easier to comprehend a nurse-computer interface by understanding this 4 Elements. These elements will help the computer system interplay.

         

The first element is hardware, this element can help the nurses to save data in storage devices like hard disk, optical disk, flash memory card and so much more, this will also allow you to enter information and view work. Hardware is consist of Input Devices that includes the keyboard, mouse, touch screen, scanner, camera, and microphone this is called Devices for entering data, another is Output Devices, this are the devices that are used to store data and can view works like hard disk, lastly is the Input/output Devices for processing and transmitting data like main board, processor, internal memory, card and communication devices. The second element is the software part of this is the graphical user interface, this GUI is most commonly do by the present computer now a days because by GUI it will provide a way to point and click with mouse or other pointing devices to select options in the screen we are like controlling what is flashed by the computer screen, compare to the command-line interface which required users to type memorized commands to run the program and accomplish tasks. The third element is user; this user is referring to the nurses. The nurse just like any user has to interact with the computer by this we are the one who will control the computer in order to do the tasks. But before using this it is required for us nurses who haven’t try using computers especially the old people now a day to have trainings in using this so that in the actual area it will be much easier for nurses to use computer. The last element is electronic data, being electronic, a computer works on discrete electrical impulses. To be useful, electronic data must undergo thre processes namely: transmission, processing, and storage. This can be stored into other physical forms by converting them into magnetic spots on hard disks, floppy disks, or magnetic tapes; or pits and bumps.
