Flashcards do conjunto (9)
- 1EPROM- initially empty
-can be written multiple times
- if there is an error in the instruction it can be removed -erased using uv light
- must be out of the device
-eprom must be entirely erased before writing - 2EEPROM-initially empty
- can be written to multiple time
-if there is an error that error can be removed
- erased using voltage
-can be erased in its original position
- does not have to be fully empty for it to be written to - 3Bufferbuffer memory is a temporary storage area in ram that stores data that is being transferred between 2 or more devices
- 4mag state mediathe surface is covered with magnetic material
the magnets are altered to represent 1s nd 0s
magnetic tapes floppy disks - 5optical state mediathe surface is covered with light sensitive material
read/written by lasers
dvd-ram cd-r - 6ssdmade of a million tiny transistors
movement of electrons is controlled by a micro chip
no moving parts
memroy sticks , mp3 player - 7embedded systemmicroprocessor within a larger system that performs one specific task
(not easily updated)
(built into larger systems) - 8ssd internalno moving parts
permanent memory
uses nand nor gates
ssd controller manages the components
the movement of electrons is used to read/write
no overwriting data - first erase then add
1st transistor floating gate
2nd transistor control gate - 9laser printeruses laser beam and rotating mirror
to draw the contents of the page on the photosensitive drum as electrostatic charge. the toner is attracted to this charge
