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, ...
Memory protection: Normally some sort of limitation on who can write to which memory, to reduce the risk that a bug or a virus can damage data or bring down the computer.

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.
Compare Contiguous memory allocation with internal fragmentation?
in early, computer system has contiguous memory allocation,each process is allocated in a single contiguous(together) memory!!(allocating into memory addresses one by one,)it has tackled memory fragmentation(both internal and external). not allocating for a fixed size memory block.so no internal fragmentation, allocating contiguously ,so no external fragmentation!!!
Contiguous memory allocation program in Linux?
malloc or calloc
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.
What is Arrays of Pointers?
An array of pointers is a contiguous block of memory that contains pointers to other memory locations. They essentially allow non-contiguous memory locations to be treated as if they were an actual array.
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
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 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 is contiguous memory?
The largest chuck of available memory that is not fragmented.
