Explanation:
Capacity of main memory=16 Bytes=24
The number of address bits= 4 bits.
The size of the word= 1 Byte=20
The word bits=0.
Number of lines =4
Number of sets required=21
The sets bits is =1
The number of offset bits=20=0
Number of tag bits= total number of address bits - (word bits + offset bits + set bits)
= 4 - 0 -0- 1
= 3 bits
