Question

Byte ordering:

a) is not a problem in modern computers

b) has been solved with specialized hardware

c) can cause a problem if ASCII files are transferred between machines

d) can cause a problem if binary files are exchanges between CPUs

e) is not a problem between a Pentium and a Sparc processor

RAID is used:

a) as a memory speed-up mechanism

b) as a tape backup policy

c) as a safer way to store data on physical disks

d) as a way to compute checksums

e) to decrease the number of physical disks in a system

Explanation / Answer

1. (D) Byte ordering can cause a problem if binary files are exchanged between CPUs - Yes it can be a problem if byte ordering is not considered while transfering data across two different computers with different byte ordering or endianness. It wont cause problem if data is transferred byte by byte but will be a problem if data is transferred in words of more than a byte

2. (C) RAID (Redundant Arrays of Independent disks) is used as a safer way to store data on physical disks - RAID uses multiple disk to increase the reliability of data on them by keeping multiple copies of same data on more than one disks.
