ITPEC IP April 2018 Question 14
In the new system environment of Company X, three systems including the customer management system, the ordering management system, and the call center system run at separate locations and connected via a network and they can complement one another in the event of a failure. Also, the system operations are managed at their respective locations. Which of the following is the greatest merit of this new system environment?
Explanation
Risks of disasters and other problems are diversified — with the systems at separate locations, one site's disaster or failure does not stop them all.
This is distributed processing: each system runs at its own location and the others can take over part of its work if it fails. A fire, power cut or earthquake at one location affects only the system there, so the risk is spread instead of concentrated at one site.
Answer (b)
Why not others:
- •(a) — operations are managed separately at each location, so they are not integrated and staff are not reduced; that is a merit of centralized processing
- •(c) — software is installed at three locations, which makes keeping versions in step harder, not easier
- •(d) — backups are taken at each location, so they are not managed in one place
Key rule: Distributed processing spreads risk and load across sites; centralized processing makes operation, version control and backup easier to manage.
