Can you distinguish between defined contribution and defined benefit plans?

Defined contribution plans:

Are post-employment benefit plans under which an entity pays fixed contributions into a separate entity (a fund) and will have no legal or constructive obligation to pay further contributions if the fund does not hold sufficient assets to pay all employee benefits relating to employee service in the current and prior periods.

Defined Benefit Plans:

Are post-employment benefit plans other than defined contribution plans. Under defined benefit plan, the employer has the obligation to pay specified amount of benefits according to the plan to the employee and all investment and actuarial risk thus fall on the entity.
