Storage (Permanent) The user can then choose to output the flyer to a page via the printer. Processing unit for graphics that converts information to colour outputs on a display. Applications like Browsers, MS Office, Notepad Games, etc., need some environment to run and perform its tasks. A Serial port only transmits 1 bit at a time and the cable is usually circular. Secondary storage differs from primary storage in that it is not directly accessible by the CPU. If the POST test detects any faults then you will hear a beep sound and the computer system would stop without booting up. An Operating System (OS) is a software that acts as an interface between computer hardware components and the user. Heat sink is a device that is attached to the processor chip which serves a purpose to draw heat from the processor to make sure that the temperature of the processor is down. So in other words most computer systems have a heat sink and a cooling fan together where they both work together to prevent components from overheating. Think of motherboards as alike an Airport, a centralised location connecting passengers (computer information) to various airplanes travelling to different destinations. A Cooling Fan is a small fan that is fitted on to the heat sink to prevent it from overheating. Secondary storage does not lose the data when the device is powered off and it is non-volatile. As certain components overheat it is necessary to have a heat sink and fan into to cool down the temperature of the components. When the data is inputted into the computer system by the user, it is then processed by the Central Processing Unit (CPU). These components are sub-categorized under softcopy and hardcopy output.
