System Access

[jonselby]

What is the difference between logical and physical acces to a computer system?

[Sensei]

Logical access occurs internally within semiconductor circuits....for example, your video card in your pc is logically addressed by the processor for operation. There's nothing mechanical there. Physical access would be something like a hard drive or cd rom. The information, in that case, is physically transferred from a spinning disk. Incidentaly, the hard drive is logically addressed to perform the physical accessing.
