tests if the system performs and functions correctly

Testing before a software is made available to the general public

Comments and suggestions from a Beta user, feedback is given before the release.

1.keep both information systems(high maintenance cost)2.replace both systems with a new one(high initial cost)3.select the best information systems from each and combine them(very difficult)4.select one over the other(policy problems)

different software entities or systems cannot operate satisfactorily on the same computer or on different computers linked by a local or wide area network.

process of identifying and correcting bugs in a computer program

contemporary delivery method that allows software and data to be hosted and managed centrally on a remote datacenter.

User documentation is shown online as well as as a hard copy. It should be well structured for easy understanding.

Help files include Manuals, email support.

accidental deletion,admisntrative errors,poor data storage,building fires,not saving the files,viruses,failure,data corruption,firmware corruption,natural disasters,hackers,physical damage,power failure

Examples would be : embedded assistance, frequently asked questions, live chat sessions, online portals, remote desktop connections

for example if the medical records of a patient in a hospital are lost, the the patient/s life can be in danger if the data cannot be retrieved, and painful examinations might have to be repeated

This allows the user their own time to understand and learn.This will allow self study

regular backup using hard disks, firewall installation, data storage in multiple locations,removed hard copies, installation of antivirus program for protection.

Online tutorials are more interactive and they allow for questions to be asked, for manual training iti is based on self discipline and self study
