What is dummy activity in job operation of a project?

Dummy Activity:

All projects consist of a number of job operations or tasks that are termed as activities. An activity is a tool of a project and this may be a process, material procurement or a material handling cycle. A dummy activity doesn’t consume time. As two activities start at similar instant of time, the head events are joined through a dotted arrow and it is termed as dummy activity. This activity may be non-critical or critical. This becomes a critical activity while its Earliest Start Time (EST) is similar as its Latest Finishing Time (LFT).
