a) RAID is a method to create live backups of physical hard disks but creating RAID will decrease the usable capacity of the hard drive. would you prefer to have backup at the cost of half of your disk space? What type of RAID would be better for a home based computer setup that has frequent power failures that could cause hard disk failures? b) Sequential and direct access are two methods to locate data in memory. Discuss why major devices now a days use direct access?How can we convert data that is written on a device that supports only sequential access to a device that only support direct access method? c) There are number of types of digital memory available, such as hard disk drive (HDD), random access memory(RAM), solid state drives (SSD) and cache memory. Is there an advantage to having multiple standards or would it be beneficial to consumers if there was only one memory standard, such as just the various sizes of SSDs? Would having a single standard be less expensive and more convenient for consum
