When the OS literature teaches you that processes aren't cows since cows needs two parents to spawn a child while a process only needs one.

Processes are hermaphrodites

I was wondering because processes and cows else have so much in common

Metaphors: abusing the nonsensical parts of terminological relationships for the entertainment of those who take time to think about them.

Also, @lamka02sk, I think you mean asexual. Hermaphrodites have both sets of sexual characteristics, but (at least so far as I know) are incapable of reproduction without assistance, just like other humans. (Hermaphrodites aren't cows, either.) The term "asexual" is less entertaining to say, though.
