Explanation / Answer

IT services provides various IT solutions to their client, this includes either :

A)Software as a service

B)Platform as a service

C)Infrastructure as a service.

MNC's relies on these IT solution providers in order to reduce the degree of the extra work load.

By making multiple computer systems available, the memory or the data present on the memory can be distributed in all the network of these computer systems. This achieves the extra layer of security, since all the data is scattered and evenly distributed among all those computers.

Abstraction of services: Consider a scenario in which a single computer system is used to complete a single task, this may take some time, lets say 'n' amount of time. Then if we use 4 more systems and made them work together, then the time required would be reduced to 'n/4', thus huge difference can be obtained.

Abstraction of Files: In order to proved some level of security, the confidential files can be evenly distributed among all the available computer systems, thus id someone gets an access to one computer system, he may have a few pieces of the file, but most of the files will still be unavailble to him.
