In a contiguous memory allocation there is no overhead during execution of a program. In a non contiguous memory allocation address translation is performed during execution.
In contiguous allocation there is no overhead during execution of a program. In noncontiguous allocation address translation is performed during execution Contiguous memory allocates single area of memory Noncontigious memory allocates several memory areas - one memory are to each component of a process

There are two types of memory allocations. 1. Static memory allocation 2. Dynamic memory allocation
Contiguous memory allocation in C programming refers to the assigning of consecutive memory blocks to a process. Contiguous memory allocation is one of the oldest and most popular memory allocation schemes in programming.
Static Memory Allocation: Allocating the total memory requirements that a data structure might need all at once without regard for the actual amount needed at execution time. Dynamic Memory Allocation: The opposite strategy of static memory allocation - Dynamic Memory Allocation, involves allocating memory as-needed.
Linked lists use dynamic memory allocation (also called "heap memory allocation", as the linked list is stored in heap memory).

Segmentation involves dividing memory into variable-sized partitions to allocate memory dynamically, while compaction rearranges memory to reduce fragmentation by moving allocated memory blocks closer together. Segmentation deals with memory allocation, while compaction improves memory utilization.
Static storage allocation is when a program dedicates an amount of memory for its use at the start of the program. Dynamic storage allocation is when a program only takes storage as it needs it.
In partition memory is divided in to fixed/variable size of the partitions . Programs are stored in partitions.In page allocation memory and programs are divided into small pages . These program pages are stored in the memory.One processor pages are need not allocate the continuous pages in memory.segmentation is the grouping of information that is treated as a logical entity.
