Paging is a memory management scheme that permits the physical- address space of process to be noncontiguous.
The advantage of contiguous memory allocation is 1. It supports fast sequential and direct access 2. It provides a good performance 3. the number of disk seek required is minimal The disadvantage of contiguous memory allocation is fragmentation.
Dfference between contiguous and noncontiguous1) In contiguous allocation there is no overhead during execution of a program.1)In noncontiguous allocation address translation is performed during execution2)Contiguous memory allocates single area of memory2)Noncontigious memory allocates several memory areas - one memory are to each component of a process

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
The advantages are they will remember the shape that you want. The disadvantages is that they will be hard to change.
There are two types of memory allocations. 1. Static memory allocation 2. Dynamic memory allocation

Hence
Advantages: Stores more information with greater precision. Disadvantages: Takes up twice the amount of memory.
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.
