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.
in contiguous allocation overhead during execution of a program. in non contiguous allocation address translation is performed during execution of a program..
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.
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.
Contiguous Allocation Linked Allocation Indexed Allocation
it is allocation strategy using variable size portions
Static storage allocation is when a program dedicates an amount of memory for its use at the start of the program. Dynamic storage allocation is when a program only takes storage as it needs it.
malloc or calloc
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
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, ...
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.
Supports fast sequential and direct access
Dfference between contiguous and noncontiguous 1) In contiguous allocation there is no overhead during execution of a program. 1)In noncontiguous allocation address translation is performed during execution 2)Contiguous memory allocates single area of memory 2)Noncontigious memory allocates several memory areas - one memory are to each component of a process
Paging is a memory management scheme that permits the physical- address space of process to be noncontiguous.
structure is a collection of heterogeneous datatypes.it stores these datatypes into contiguous memory allocation
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!!!
Storage allocation is a method of saving overall disk space in computer programming terms. This method involves saving similar pieces of data in the same location.
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… Read More
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".
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.
They mostly deal with pointers and new operators in memory.

Memory allocation is the act of reserving a chunk of memory for some set of data. In programming terms, this is normally done by declaring a variable. Large arrays of data will require large blocks of contiguous memory, which the programmer must request from the operating system.
When seeking a contiguous block of memory to allocate, the first block that is at least as large as the size being requested is allocated.
What are the three major activities of an operating system in regard to secondary-storage management?
1. Free space management. 2. Storage allocation. 3. Disk scheduling. Your Welcome.
Managing the free space available on the secondary-storage device. Allocation of storage space when new files have to be written. Scheduling the requests for memory access.
A contiguous file in a computer is one that is placed on a storage drive in such a way that it is in sequential portions of the drive. This is generally regarded as advantageous because it results in better performance by decreasing the amount of time it takes the computer to read the data (compared to when a single file is spread over a larger portion of the drive and not located in contiguous sectors)… Read More

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.
Differentiate between contiguous and non contiguous memory
Contiguous means touching. Alaska is not one of the contiguous states.
My research shows that usage of "contiguous to" has greatly exceeded "contiguous with" for several centuries until relatively recently. Usage of "contiguous to" still exceeds "contiguous with," but by a very narrow margin. Try plugging these into a Google n-gram and you'll see the usage history since 1800.
"is my disease contiguous
Contiguous because everyone wanted to play it see it etc it spread all across usa and the world
A certain amount of disk space is used for the file allocation table (FAT). The FAT is like a books table of contents.
A one-dimensional array is always represented as a single contiguous block of memory. The size of the allocation is determined by the array's type and the number of elements of that type. For instance, if you create an array of 10 elements where each element is 4 bytes in length, the total allocation will be 40 bytes. The array name is a reference to the start of the allocation and individual elements are accessed via… Read More
in java the memory allocation can be dynamic in nature. The java array enables the user to store values of the same type in contiguous memory allocations. Arrays are always a fixed length abstracted data structure which can not be altered when required.
48 states are contiguous. Two states, Alaska and Hawaii are non-contiguous.
What are the advantages and disadvantages of dynamic memory allocation and the allocation of files in secondary storage?
Two disadvantages of dynamic allocation: a) Freeing memory b) Fragmentation Freeing Memory The user is responsible for freeing up memory when he is finished with it. This is a serious responsibility, a potential source of bugs that are very hard to find. For example, suppose you free up a location before you're actually finished with it. Then further access to the location will either cause a run-time error (memory violation) or, what is worse (but… Read More
Spain is contiguous with Portugal and France

Contiguous means physically in contact. So for example, of the 50 American states, 48 are contiguous.
static allocation is when something is moved to a location permanantally and dynamic allocation is when something is moved temporarily, but will move again.
The word "allocation" is a noun and means "distribution". Synonyms of the world "allocation" would be: "allotment", "apportionment", "portion", "quota", "ration", and "share".
Four parcels of land have contiguous borders
Contiguous is pronounced - kon-tig-you-us
the southern ocean is contiguous with the atlantic
No, not 50; only 48 states are contiguous.
Contiguous means part of the continental United States. So the non-contiguous states are Alaska and Hawaii.
