A computer, or CPU does not multitask. A person multitasks when a
person uses two or more programs simultaneously (e.g. listening to
music while working on a spreadsheet). A CPU just adds numbers.
Subtraction involves the addition of negative integers. Multiplication
involves addition a number of times, and division involves subtraction
a number of times. Computer memory allows the computer to "count"
or keep track of all these numbers being added, or counted. Memory
allocates special characters to certain numbers. Everything gets
reduced to machine language, 1's and 0's, "on and off". I think you
are thinking of what is called parallel processors, or parallel computing,
or cloud computing.

Regarding Faizalhuques quote, Can you not judge and love another,
simultaneously? Can you not judge without meeting out measure?
"Hey, that's not cool" is that not what a loving parent might teach a
child, poking him in the rib with his finger, "a rod of correction"? For
to love somebody is to want that person to be holy. You decide for
yourself what is right, and what is wrong, but the question is, Will you
decide correctly? It is not a choice between two philosophies called
Moral Relativism and Moral Absolutism, but both together help describe
the "real world". You need both Truth and Love. It is a kind of parallel
computing, or multitasking.
