Explanation:

• The timer is counted the inside the clock whereas the counter counted outside the clock i.e  external clock is there in the counter.

• Because of constant frequency in Timer the interrupt is generated whereas there is varying in the frequency so interrupt is not generated in a limited period of time.

• To measure the frequency of undefined sources used the timer. Counter is not used for this.
