SCCM Software Update Reporting - Understanding the Report

Question

I could use some help in understanding what makes a computer compliant and what makes a computer non-compliant in regards to SCCM’s Software Update reporting.
When I look at a report for a compliant computer and a non-compliant computer, I do not see the pattern which would cause a computer to be compliant or non-compliant.
Example for two computers:
For each report, every item with a check mark in the Approved column also has a check mark in the Installed column. 
For each report, if there is a check mark in the Is Required column, there are no check marks in the other two columns for that row.
Yet one computer shows as compliant while the other shows as non-compliant.
So in regards to the three columns in a Software Update report, what should be checked or un-checked to indicate whether a computer is compliant or not?

Answer 1

Okay,
When you run a Compliance 1 report, the resulting report lists three rows:
One row for “Non-compliant”
The second row for “Compliance state unknown”
The third for “Compliant”
Drilling down into each row displays the computers that fall under the three categories above. 
Drilling down further on specific computers within each category shows each update on its own row with three columns, “Approved”, “Installed” and “Is
Required”.
I have been assuming that a computer lacking approved updates would fall under the “Non-compliant” report while a computer with all approved updates installed would
fall under the “Compliant” report. (correct?)
With this assumption, I have comparing compliant vs non-compliant computer reports by looking at the “Approved”, “Installed”, and “Is Required”
column of each.  But I am not seeing the pattern that would designate one computer has compliant and another non-compliant.
So it is the report (not me) that is telling what is compliant and what is not compliant.
Am I understanding this incorrectly and if so, please fill me in (details would be great)?
