IG theory





















Hardware


The physical components of a system



















Software 

Set of commands that are processed for an output. For example utility software which is used to change the system (control panel or system preferences). Application software such as Word Processing and Call of Duty. The operating system is also software, it is used so everything such as the printer and word can function and work together.  

Components

Input devices: CPU (central processing unit), ROM (read only memory) is non volatile and is permanent, RAM (random access memory) holds what you are currently doing such as playing a game, it's continously changing and is volatile. RAM and ROM are primary memory, secondary storage is the hard drive.
Output devices: Printers such as laser. 

Interface

GUI's (graphical user interface)  are WIMP's (windows, icons, menu's, pointers) and Command line interface.
