#COA #Disk
Consider a disk which has 64 tracks , in every track there are 1024 sectors , each sector has 2048 B . The disk is moving with 3000 RPM . Let the avg seek time is 10 ms and it is required to read a file of 64KB which was placed in outer track ... sector onwards . The current position of read/write head is 16th sector of inner track. What is the time taken to complete disk read operation?

ACE Test-4(GCO-2)
Correct Statements ??? S1 : Generally I/O mapped I/O technique is used to connect more number of I/O devices then memory mapped I/O technique. S2 : Processor generates memory read (MRD) and memory write (MWR) control signals while communication with I/ ... I/O, the valuable memory space address is wasted due to the utilization of this memory space address to the I/O devices.
