Por que alguns processos são destacados na parte superior? O destaque tem um significado especial? Obrigado!

Para expandir a resposta de Doug, observe os estados dos processos. Todos, exceto os três processos destacados, estão no estado S
e os três processos destacados estão no estado R
. Os estados do processo são fornecidos na seção 3a, item 20 da página de top
manual :
20. S -- Process Status
The status of the task which can be one of:
D = uninterruptible sleep
R = running
S = sleeping
T = traced or stopped
Z = zombie
Tasks shown as running should be more properly thought of as
'ready to run' -- their task_struct is simply represented on
the Linux run-queue. Even without a true SMP machine, you may
see numerous tasks in this state depending on top's delay
interval and nice value.

Changes highlighting for "running" tasks. For additional
insight into this task state, see topic 3a. DESCRIPTIONS of
Fields, the 'S' field (Process Status).

tty escape sequences.
