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, ...
What is external fragmentation in operating system?
External fragmentation refers to the division of free storage into small pieces over a period of time, due to an inefficient memory allocation algorithm, resulting in the lack of sufficient storage for another program because these small pieces are not contiguous.
What is contiguous memory?
The largest chuck of available memory that is not fragmented.
Difference between internal fragmentation and external fragmentation in operating system?
Fragmentation occurs in a dynamic memory allocation system when many of the free blocks are too small to satisfy any request. External Fragmentation: External Fragmentation happens when a dynamic memory allocation algorithm allocates some memory and a small piece is left over that cannot be effectively used. If too much external fragmentation occurs, the amount of usable memory is drastically reduced. Total memory space exists to satisfy a request, but it is not contiguous. Internal Fragmentation: Internal fragmentation is the space wasted inside of allocated memory blocks because of restriction on the allowed sizes of allocated blocks. Allocated memory may be slightly larger than requested memory; this size difference is memory internal to a partition, but not being used
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.
What is the difference between contiguous and non contiguous memory allocation?
in contiguous allocation overhead during execution of a program.in non contiguous allocation address translation is performed during execution of a program..
What is contiguous storage allocation?
Contiguous means to share an edge or boundary, touching, adjacent, neighbouring and so on. Thus contiguous storage allocation is any allocation that consumes two or more contiguous storage elements. In the case of contiguous memory allocation, this means two or more contiguous memory addresses are allocated. A one-dimensional array is an example of a contiguous memory allocation, where one array element (a data type) is immediately followed by the next.
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.

What are advantages and disadvantages of contiguous memory allocation?
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.
Difference between contiguous and non contiguous memory?
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
