Which of the following is not a contiguous memory management technique...
Concept:
Contiguous memory management:
A traditional memory allocation model is contiguous memory allocation. In this case, a system gives a process access to successive memory blocks, or memory blocks with consecutive addresses. One of the earliest types of memory allocation is contiguous memory allocation.
There are three types of contiguous memory management:
- Over lays
- Partition
- Buddy system
Paging is a non-contiguous memory allocation technique that divides secondary and main memory into equal-size divisions. Secondary memory partitions are referred to as pages, whilst major memory partitions are referred to as frames.
Hence the correct answer is Paging.

Contiguous Memory Management Techniques
Contiguous memory management techniques are used to allocate memory in a contiguous manner to processes. Among the techniques mentioned, paging is not a contiguous memory management technique.
Overlays
- Overlays involve dividing a program into smaller modules and loading only the required modules into memory at any given time.
- This allows for efficient use of memory and can help overcome the limitations of small memory sizes.
Partition
- Partitioning involves dividing the memory into fixed-size or variable-size partitions and allocating these partitions to processes.
- Each process is allocated a partition based on its memory requirements.
Paging
- Paging is a non-contiguous memory management technique where the physical memory is divided into fixed-size blocks called pages.
- Processes are divided into fixed-size blocks called pages as well, and these pages are loaded into any available physical memory frame.
- This allows for efficient use of memory and simplifies memory management.
Buddy System
- The buddy system is a memory allocation technique that divides memory into blocks of various sizes.
- When a memory request is made, the system searches for a block of the appropriate size or splits a larger block into smaller ones to fulfill the request.
- This technique helps reduce fragmentation and improve memory utilization.
