Describe acceptance testing, list one manual other than the user manual for a software system, and give two reasons for software maintenance.

a) Acceptance testing is the final phase of software testing where the system is tested to ensure it meets the specified requirements and is ready for delivery to end-users. It verifies that the software functions as intended in a real-world environment.

b) One manual other than the user manual that would be provided with a new software system is the Technical manual.

c) Two reasons why a software system will require maintenance are:

• To correct errors or bugs discovered after the system has been deployed.
• To adapt the software to changes in its operating environment, such as new hardware or operating system versions.
