You have a RAID level 4 system with eight data disks and one parity disk. (a) How many disk reads and disk writes must you make to write one data stripe if you do not make use of the old data and...

disk reads and disk writes must you make to write one data stripe if you do not make use of

the old data and parity values?
(b)
How many disk reads and disk writes must you make to

write one data stripe if you do make use of the old data and parity values?
12. *(a)
How many data bits are required to store one of the decimal digits 0 through 9?
*(b)

How many parity bits are required to
detect
a single error?
(c)
Write a single-error detection

code using even parity. Underline the parity bits.
(d)
