What is the difference between faulty coordination and faulty parallelism? [closed]

What is the difference between the two errors ? I've tried to understand the difference between them , but none of the sources helps .

Faulty coordination is joining two clauses in such a way that the meaning is illogical:

The iPhone is the best smart phone, and I bought one.

This should be one of

Because the iPhone is the best smart phone, I bought one.
The iPhone is the best smart phone, so I bought one.

Faulty parallelism is mixing different syntactic structures when they should be the same:

I enjoy reading, writing, and to calculate.

which should be

I enjoy readying, writing, and calculating.
