Document Summary
Input device-keyboard, mouse, touch screen(optical character/mark recognition reading) Output device-monitor(cathode ray tube or cpt and liquid crystal display (lcd), printer. The processing device contains the cpu and the main memory. The cpu has two components, the alu and the control unit. Mother board-contains all the components that do the actual processing work. Power supply-converts standard 110/240 volt ac to lower voltages such as 5/10 volt dc for use in the computer. Fan-low voltages device designed to protect the computer from the high heat generated by the. Central processing unit (cpu): performs the operations of the computer using two components: Control unit: this device interprets instructions and transmits direction to the computers components. Arithmetic logic unit(alu): device performs math as well as logical operations by interpreting and executing instructions. Data code to represent and transfer data between computers and network systems. This storage is used for temporary storage to support computer processing and comes in ram and rom types.
