Solution
The Correct answer is Option 1: A-IV, B-III, C-I, D-II
A. Address Space - Virtual Address (IV):
Address Space refers to the set of all virtual addresses generated by a program. Virtual address space is the range of memory addresses that a process can use.
It is abstracted from the physical memory by the operating system, allowing programs to utilize more memory than what is physically available.
Hence, Address Space is associated with Virtual Address.
B. Memory Space - Physical Address (III):
Memory Space refers to the actual physical memory available in the system. Physical addresses are the real addresses in memory hardware, used to access memory locations directly.
The physical address is mapped from the logical or virtual address by the operating system and memory management unit.
Hence, Memory Space is associated with Physical Address.
C. Cache Memory - Associative Mapping (I):
Cache Memory is a small, high-speed storage location that stores frequently accessed data to speed up processing.
Associative Mapping is a technique used in cache memory where data is stored and accessed based on its content rather than its memory address.
It allows faster data retrieval and efficient memory usage, making it ideal for cache memory.
Hence, Cache Memory is associated with Associative Mapping.
D. Segmented Program - Logical Address (II):
Segmented programming divides a program into segments like code, data, and stack, which are stored in separate memory locations.
Logical addresses are generated within a segmented program to reference memory locations within those segments.
The logical address is later translated into physical addresses during execution.
Hence, Segmented Program is associated with Logical Address.
