Focus vs Multi-task

Can they coexist?

Focus:
1. Close or narrow attention; concentration
~ The Free Dictionary @ http://www.thefreedictionary.com

2. The concentration of attention or energy on something
~ WordReference.com @ http://www.wordreference.com

Concentrate on 'something' instead of 'many-thing' ? =)

More interesting, what is multitask?

Multitask is the verb of multitasking and multitasking means:
The concurrent operation by one central processing unit of two or more processes
~ The Free Dictionary @ http://www.thefreedictionary.com

Hmm.... so that begs the question of are human brains to be considered a form of 'central processing unit' ? After all, humans are suppose to be able to function in a parallel form and multitask. Very interesting thought on that. I wonder what recent progress has been made in trying to replicate human brain function by simulating single unit neurons and linking them together in software.
