Solution
In computer architecture, when data is transferred from main memory to cache memory,
a process known as mapping determines where each block of main memory
will be placed in the cache. There are different types of mapping techniques such as
Direct Mapping, Associative Mapping, and Set-Associative Mapping.
This process ensures efficient and quick access to frequently used data.
Match List I with List II:
Choose the correct answer from the options given below:
| List I | List II |
|---|---|
| A. Address Space | I. Associative Mapping |
| B. Memory Space | II. Logical address |
| C. Cache Memory | III. Physical address |
| D. Segmented Program | IV. Virtual address |

Solution
- A. Address Space → Virtual Address (IV)
Address space refers to the range of virtual addresses a process can use in memory. - B. Memory Space → Physical Address (III)
Memory space corresponds to the actual physical memory locations in RAM. - C. Cache Memory → Associative Mapping (I)
Cache memory uses mapping techniques such as associative mapping to store data efficiently. - D. Segmented Program → Logical Address (II)
In segmentation, programs are divided into segments, each referenced by logical addresses.
The computer needs to process each instruction with the following sequence of steps:
A. Calculate the effective address
B. Fetch the instruction from memory
C. Decode the instruction
D. Fetch the operands from the memory
E. Execute the instruction

Solution
First fetch the instruction (B), then decode it (C). If required, compute the effective address (A), fetch the operands (D), and finally execute the instruction (E).
