Hardware:the physical components in a system
Software:disk utility software is used to change the system(control panel in system preferences) 3 types=
-set of commands
-operating system
-application
Components: input device (eg. keyboard,mouse) CPU, RAM(random access memory)-holds what's going on now/ ROM(read only memory(non-volatile), Secondary Storage(hardrive), Output(printer)

Interface: One thing talking to another, allows communication. Allowing you to talk to the machine.GUI(graphical user interface) GUI's are WIMPS(windows,icons,menus,pointers),Command line interface(when a geek types what he wants the computer to do)

Primary memory is closest to the CPU,which is RAM/ROM. Secondary storage is the hardware
