Task vs. Assignment
Task is broader.

I need to complete a task.
This doesn’t say who gave it to you.

Task vs. Duty
A task is something you need to do.
A duty is something you are expected or required to do because of your role.

The second sentence emphasizes obligation.
Task vs. Responsibility
A task is generally a specific piece of work.
A responsibility can be a broader area that includes multiple tasks.

This distinction is especially useful in job descriptions and résumés.
Task vs. Chore
A chore is usually routine, repetitive, or somewhat unpleasant work.

Washing the car is a chore.
The second sentence suggests that the work is a routine obligation and perhaps not particularly enjoyable.

A project can contain many tasks.
For example:

Tasks:

Calling each individual step a project would be less precise.

An objective is a goal you want to achieve.
A task is an action you perform to help achieve that goal.
Objective: Increase customer satisfaction.
Tasks: Survey customers, review complaints, and improve support procedures.
This distinction matters in business and project planning.
Task vs. Errand
An errand is a short trip or practical activity performed to accomplish something.
