fender squier affinity strat

What’s the difference between these two guitars?
What is the difference between a standard/normal SQUIER (NOT FENDER) stratocaster, and a SQUIER (AGAIN, NOT FENDER) Affinity Series Stratocaster.
Also, what is the difference between a normal affinity series strat and a “two tone” affinity series strat. If they both have at least two volume controls, doesn’t that mean they have at least two pickups, which means at least two tones?
Thanks!

The standard has a slightly wider neck (42mm at the nut vs 40.9mm on the Affinity).
“Two tone” means it has individual tone controls for two pickups.
