What are the differences among Task, Duty and Responsibility?

Task:   Specific work given to anybody to complete within limited time period. 

Duty:   Job Structure employer hire for.

Responsibility:  Employees interest of doing his duty.

Sir, This is my own answer, may be wrong or right but I try to create.

In my View: 

• Task is a smaller part of a job that has to be performed within specific time, circumstances, and / or place.
• A duty is a liability upon an employee to perform some specific tasks as assigned to him by the organization from time to time as a part of his job.
• A responsibility is a degree of accountability of an employee for some task he performed of has to perform.

Tasks are a some works give to you do it on time. action will be possible in the same area or another area you accomplished .Duty: is part of the job description before you start the work .Responsibility : is supervising the group of persons to work on achieving the goals of the administration

TASK IS THE UNIR OF A WORK , DUTY: THE RESPONSIBILITY WHICH IS ASSIGNED BY THE SUPERVISOR OR BOSS.
