• input is the component that allows the computer to receive data from the outside world
• proccessing is done by the cpu and the results are either sent to an output or transferred to secondary storage
• storage primary and secondary
• the ouput componenet is for dislpaying data
• the purpose of the cpu is to proccess data and to control the rest of the computer system
• the control unit directs the flow of intructions. the control unit checks the intructions in the register
• the athmetic logic unit performs mathamatical or logic functions on values passing on from the register
• the registers temporily store data from the cpu. storres the results from the calculations of the alu
• teh cache hold data and intructions that the cpu is likely to use
• the cache stores the instructions
• rom means read only memory
• optical laser beams are projected onto a disc
• magnetic uses a magnetic plate and a read write head
• volatile = stored temporally
• non volatile = permeant
• the gpu role is used to show images the better the gpu the better the image quality
• motherboard is how all the computer parts communicate to each other
• as the number of cores increase the computer has more power to execute multiple processes at once
• rom stores your apps
• flash is a usb that can store music and videos
• Fetch decode cycle is when the cpu gets data from the rom which is then temporally stored in the registers. then it is decoded by the control unit. and then its sent to the alu. this is then repeated for every instruction
