With time, the classification systems have undergone numerous alterations. Aristotle made the first attempt at classification. He divided plants into three categories: trees, shrubs, and herbs.
On the other side, red blood cell presence or absence was used to categorise animals. The known organisms cannot all be categorised using this technique.
As a result, Linnaeus provided a two-kingdom classification scheme. Kingdom Plantae and kingdom Animalia are its constituent parts. However, this approach did not distinguish between eukaryotes and prokaryotes or between unicellular and multicellular creatures. As a result, there were numerous species that fell outside of the two kingdoms.
Thus, in order to classify the three kingdoms, Ernest Haeckel divided unicellular eukaryotic organisms into a separate kingdom called Protista.

Answer:
2048 blocks
Explanation:
From the information given:
The memory size of a computer with fully associative cache = 2¹⁶ bytes
The no. of blocks in a single cache = 64
In which each block size = 32 bytes
The no of blocks in the main memory = memory size ÷ block size
The no of blocks in the main memory = 2¹⁶ ÷ 32
The no of blocks in the main memory = 2¹⁶ ÷ 2⁵
The no of blocks in the main memory = 
The no of blocks in the main memory = 2¹¹
The no of blocks in the main memory = 2048 blocks
