The control group is necessary to know if the factor being tested is making a difference in the experimental group. Both should be subject to the same conditions, except for the one condition or factor being tested on the experimental group. Differences between the outcomes of the two groups, good or bad, can then be attributed to the one factor that is different. Without the control, it would be most difficult to tell what the factor being tested had done, because it's not really possible to tell what would have happened without it.

In an experiment a group that is identical to a control group except for one factor and that is compared with the control group?

That group is called the experimental group, and it is used to test the effect of changing the specific factor that distinguishes it from the control group. By comparing the results of the experimental group with the control group, scientists can determine the impact of that particular factor on the outcome of the experiment.
