Question

I am really confused, In questions like this, when do we have to use the access time? Is the access time included in writing/updation time here?

Comments

write through mecahnism updations done only when any modifications done in either memories i.e) replace previous data by origina data like.

so in case of read hit no need of updations.

yes,that concept is wrong.

I am asking in case of write hit and not read hit. The question asks for avg writing time. So definitely we have to consider updations,  isn't it?

---

if it is write hit what is the need of updations.required data is in cache i think no need of updations.
