What is the difference between event and task in Salesforce?

An event is a calendar event scheduled for a specific day and time.
Examples:
1) Meetings
2) Scheduled Conference Calls
A task is an activity not scheduled for an exact day and time. You can specify a due date for a task or there may not be a particular time or date that the tasks or activities need to be completed by.
Examples:
- A list of phone calls you need to make.
- An email that needs to be sent.
