Physical memory is the total RAM in a machine (e.g. 512x2 = 1024) and logical memory is the amount of space allocated to a logical partition.
But is would the physical and logical memory of a USB. Is there such a thing as physical and logical memory on a USB stick or am I talking nonsense?
Cheers!
I gueess you are making a bit of confusion.
Leave the RAM alone.
On a normal hard disk drive, you have a "PhysicalDrive" that represents the whole device and (one or more) "LogicalDrive"(s) that represent the partition(s).
On a floppy or "super-floppy" device the PhysicalDrive is the same as the LogicalDrive, since there are no partitions and no hidden sectors.
A USB drive is conceptually a Mass Storage Device, identical to a HDD.
And just like on a HDD the manufacturer puts a few "spare reserved sectors", a USB pendrive usually has a number of sectors that are only accessible through special utilities.
So, a USB pendrive has
- a "logical memory" (the part that the OS normally "sees", LogicalDrive(s))
- a "physical memory" (the above + the part that the OS can "see" with utilities accessing the PhysicalDrive)
- a "hardware memory" (the actual capacity of the chips, that cannot normally be entirely accessed)
