sign-on (computer)

[James Zhang]

Hi, teachers. I have some questions with the sentence below.
Integration with centralized corporate directories and authentication
services enable single sign-on for both telephony and other business-
critical applications.
My questions are:
1. What does "sign-on" mean here? registration?
2. Would you please explain the suffix-critical for me?

Thank you. Have a good day.

Many businesses have many different computer systems, each requiring users to log on and enter their passwords = sign-on.

Single sign-on is a service that allows users to do this only once. The service itself will negotiate any log-on dialogues required by other systems.

Business-critical is a much abused term.

It should be applied only to applications that are critical to the survival of the business.
