How many 32-bit integers can be stored in a 16-byte cache?

A 32-bit integer requires 4 bytes of storage (since 32 bits divided by 8 bits per byte equals 4 bytes). A 16-byte cache can therefore store ( \frac{16 \text{ bytes}}{4 \text{ bytes/integer}} = 4 ) 32-bit integers. Thus, a 16-byte cache can hold a total of 4 32-bit integers.
