Happy Hump day everyone time for another riddle to exercise your brain 🙂

Bit by Bit, from where I sit,

Through me all must flow.

My mother holds me tightly,

And brings me all I know.

Encased within a tower,

Atop a desk, or lap, or palm;

When fans are all around me,

I must stay cool and calm.

If you think you know the answer, then by all means post it in the comment section 😉 Once the correct answer is posted I will confirm!
