Contiguous memory allocation in C programming refers to theassigning of consecutive memory blocks to a process. Contiguousmemory allocation is one of the oldest and most popul…ar memoryallocation schemes in programming.
In a contiguous memory allocation there is no overhead duringexecution of a program. In a non contiguous memory allocationaddress translation is performed during execution.
to set apart for a particular purpose. EXAMPLE!- to allocate funds for new projects.
Supports fast sequential and direct access
it is allocation strategy using variable size portions
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 conti…guous 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.
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.
Contiguous is a word that is used normally when objects are spatially adjacent and Continuous is a word that is normally used when events are adjacent in time. This usage is… probably the reason why arrays are "contiguously" allocated and not "continuously" allocated. On the other hand, a function f(t) is "continuous" and not "contiguous".
in early, computer system has contiguous memory allocation,eachprocess is allocated in a single contiguous(together)memory!!(allocating into memory addresses one by one,)it ha…stackled memory fragmentation(both internal and external). notallocating for a fixed size memory block.so no internalfragmentation, allocating contiguously ,so no external fragmentation!!!

in contiguous allocation overhead during execution of a program. in non contiguous allocation address translation is performed during execution of a program..
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 i…s minimal The disadvantage of contiguous memory allocation is fragmentation.
