Difference between cron, crontab, and cronjob?

Question

Technically speaking, what is the difference between a cron, crontab, and cronjob?

From what I can gather, cron is the utility on the server, crontab is a file which contains the time intervals and commands, and cronjob is the actual command (or file/script which contains commands).

Is this correct?

Answer 1

cron is the name of the tool, crontab is generally the file that lists the jobs that cron will be executing, and those jobs are, surprise surprise, cronjobs.
