When memory allocation is , it means all portions of the program and OS are loaded into sequential locations in memory.

Contiguous

Explanation:

A Contiguous memory allocation is known to be a classical memory allocation model. In this situation, we have a system which assigns consecutive memory blocks to a process. It is one of the oldest methods of memory allocation. If the process is in need of execution, the memory would be requested by the process. The processes size would then be compared to the amount of Contiguous memory that is available for the execution of the process.
