DES works by using the same key to encrypt and decrypt a message, so both the sender and the receiver must know and use the same private key. Once the go-to, symmetric-key algorithm for the encryption of electronic data, DES has been superseded by the more secure Advanced Encryption Standard (AES) algorithm.

6. 64 MB
Explanation:
Following is the solution for question step-by-step:
<u>Part 1:</u>
No. of Tag bits = No. of bits to represent
Tag bits = Main memory - cache size bits -------- (A)
Given:
Main memory = 128 KB =
Cache Memory = 16 KB =
Putting values in A:
Tag bits = 17 - 14 = 3 bits
<u>Part 2:</u>
Tag bits = Main memory - cache size bits -------- (A)
Given:
Main memory = 32 GB =
Cache Memory = 16 KB =
Putting values in A:
Tag bits = 35 - 15 = 20 bits
<u>Part 3:</u>
Given:
Tag bits = 7
Cache Memory = 512 KB =
So from equation A
7 = Main Memory size - 19
Main Memory = 7 + 19
Main memory = 26
OR
Main Memory =
<u>Part 4:</u>
Given that:
Main Memory Size =
Tag bits = 10
Cache Memory Bits = 34 - 10 = 24
Cache Memory Size =
<u>Part 5:</u>
Given that:
Main Memory Size = 64 MB =
Tag bits = 10
Cache Memory Bits = 26 - 10 = 16
Cache Memory Size =
<u>Part 6:</u>
Cache Memory = 512 KB =
Tag Bits = 7
Main Memory Bits = 19 + 7 = 26
Main Memory size =
