Task (30 mins)
System software runs the hardware and applications. The best known example of systems software is the operating system which manages all of the programs in a computer as the interface between the user and the computer. The other systems software is


 * **BIOS** (Basic Input Output System) which starts the computer system and manages data flow between the O/S and attached devices
 * **Firmware - Boot program** - loads the o/s into the computers RAM
 * **Assembler** - takes the basic instructions and converts them into a pattern of bits that the processor can use
 * **Device Driver** - controls attached devices like printer/mouse etc
 * **System Utilities** - such as disk defragmenter

Create a presentation/video/animation/graphic to show how system software works together. The only software stipulation is **NO POWERPOINT.** Some suggestions include, PowToon, WeVideo, Prezi, Google Slides, Google Drawings. This has also been set as a task on Google Classroom - finished work should be linked/uploaded on FRIDAY.
