A notice of ruling or entry of order is generally served right after the hearing and filed with the court. This notice starts critical timelines for challenging the order or ruling.
Normally, if a notice of ruling is required, it is served and filed right after the hearing, and in most cases, no longer than 5 days afterwards. In regular practice, however, notice is usually "waived" if all of the parties were present at the hearing.
A notice of ruling if served, must also be filed with the court.
There is no penalty per se for failing to serve a notice of ruling, UNLESS the failure to serve notice causes prejudice to another party in the litigation. For example, if the plaintiff was supposed to give notice of a future hearing date but fails to do so, causing another party not to appear and causing a colossal waste of time for the court and other parties, the court might impose sanctions for failure to give notice of the court's ruling.

I agree with Mr. Chen, but add a couple of observations for next time. Following the next hearing, consider agreeing to "waive notice;" if all parties are present or represented at the hearing, they can agree to waive notice such that nobody must give notice of the ruling.
Alternatively, consider asking the court if the other party can give notice, especially if the other party is represented by an attorney.
