Answer / vishnu
Cron can be scheduled with different choices
(minute,hour,month,dayofmonth,dayofweek). cron can be
edited,deleted,listed,scheduled at any time and for
repeated time intervals.
AT can be scheduled for once.cannot be edited, can be
deleted, can be listed.
so, 2 main differences:-
cron:can be scheduled for repeated jobs
AT: can be scheduled for only once
cron can be edited
AT cannot be edited, after its schedule.
both can facilitate listing and deletion
