Question No 1 10 Marks
A hard drive has 4 surfaces, with 512 tracks per surface and constant 64 sectors per track. Sector size is 2K byte. The average seek time is 3 ms, the drive runs at 3,600 rpm.
a. What is the drive capacity? (5)
b. What is average access time for the drive? (5)
Question No 2 10 Marks
Use the hamming code to encode the following 4-bit values (8 marks)
Also write down the encoding scheme (2 mark)
Total (8+2 = 10 marks)
A. 0110
B. 1001
C. 0000
D. 1111
Note : Use odd bit parity to encode above values
