2. Suppose we have a magnetic disk with the following parameters. # heads # cylinders # sectors per track sector size controller overhead average seek time rotation speed 8192 128 sectors/track 512 bytes 1 ms 5 ms 7200 revolutions/minute 1) What is the size (in bytes) of the disk? 2) How much data (in bytes) can be accessed without repositioning the read heads? 3) What is the data transfer rate (in bytes/sec) for the disk? 4) What is the average time (in seconds) to read a 50 Kbyte file. Assume the file is contiguously stored in a single track. 2.
