What part of the OSI Model is responsible for Logical Addressing and Routing?
Network
the __ __ describes the time that is taken to position the R/W heads across the platter with a radial movement. In other words, it is the time that is taken to position and settle the arm and the head over the correct track. The lower the seek time, the faster the I/O operation.
seek time
