What is contiguous allocation?
Paging is a memory management scheme that permits the physical- address space of process to be noncontiguous.
advantages of static partition allocation scheme?
It supports multiprogramming since multiple processes can be stored inside the main memory.
What are types of memory allocation?
There are two types of memory allocations. 1. Static memory allocation 2. Dynamic memory allocation
What is paging?
Paging is a memory management scheme, in which data is fetched from the disk to memory in the form of equal size blocks called pages.paging is a method for allowing the non-contiguous allocation of memory space to processes when nedded.
WHAT IS SINGLE USER CONTIGUOS SCHEME?
Single user contiguous scheme is a memory allocation technique where a single block of contiguous memory is allocated to a process. This means that the entire memory space needed by a process must be available in a single block without any breaks or fragmentation. It simplifies memory management but can lead to wastage of memory due to fragmentation.
What is meant by contiguous memory allocation in C?
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.
Compare and contrast dynamic memory allocation and the allocation of files in secondary storage?
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.
What Linked list uses.type of memory allocation?
Linked lists use dynamic memory allocation (also called "heap memory allocation", as the linked list is stored in heap memory).
What is contiguous memory allocation in os?
Memory allocation: When a program asks for memory and gets it. Contiguous allocation: When the memory is in one big block, for example memory addresses 1000-2000, as opposed to "fragmented allocation" where the memory comes as several smaller blocks in different places, for example memory addresses 1000-1050, 2050-2125, ...
How do you display matrix in c using dynamic memory allocation?
Memory allocation is not necessary to display a matrix.

Difference between contiguous and non contiguous memory allocation?
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.
