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.

Paging is a memory management scheme that permits the physical- address space of process to be noncontiguous.
in continuous memory aallocation method no overhaead for trhe execution of progtram. and in non continuous memory aalocation there is overhead on the execution of program
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.
Differentiate between contiguous and non contiguous memory
Supports fast sequential and direct access
it is allocation strategy using variable size portions
In contiguous allocation there is no overhead during execution of a program.. In noncontiguous allocation address translation is performed during execution. Contiguous memor…y allocates single area of memory. Noncontigious memory allocates several memory areas - one memory are to each component of a process
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!!!

Sharing is caring: this one curtesy of badmoon36: According to Wikipedia, Alaskans and Hawaiians don't typically use either phrase, instead preferring "the mainland", "sta…teside", "outside" or "the lower 48" (these last two exclusive to AK). Wiki also claims the phrase "continental United States" originated around 1898, when the US acquired Hawaii and other off-shore territories. Proper linguists could argue against this. "Continental" is easily defined, but "contiguous" is often mistaken. According to Dictionary.com, "contiguous" has a few definitions, and not only means "touching" or "in contact" (as in real estate), but also "near" or "in close proximity without actually touching." This then, when applied to this issue, could include Alaska, depending on whether you regard a little less than 500 miles as "close proximity". To complicate things further, there is also the "conterminous United States". "Conterminous" means having common borders, the definition often erroneously attributed to "contiguous".
in contiguous allocation overhead during execution of a program. in non contiguous allocation address translation is performed during execution of a program..
contiguous is "separated in space" and continuous is "separated in time"
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.
