If a computer system has both data cache and TLB. During the address translation process first what will be checked? that is whether we will first search data in the data cache or we will search for address in TLB?

If there is a TLB then TLB will be searched first followed by the caches.

But why we will search TLB first? If we can find actual data in Data cache then what is the need of searching for its address in TLB? Plz explain
