Linked lists use dynamic memory allocation (also called "heap memory allocation", as the linked list is stored in heap memory).

Sequential allocation refers specifically to arrays. An array is, by definition, a contiguous block of memory. The index of the array is used as an offset from the memory address of the beginning of the array - this is why access to any element in an array takes a constant amount of time to compute. "Linked allocation" is best described by linked lists. These data structures are connected by a series of nodes. A node contains at least two pieces of information: some piece of data and a reference (link) to the next node in the chain. Since changing the position of a node in a linked list only requires changing references to other nodes, insertion and deletion is trivial. Note that these "referential" linked data structures are not the only way to link data, just the easiest to understand and implement.
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.

A linked list implemented with an array defeats the purpose of using a linked list, which is to address the memory allocation problems associated with arrays.
In a centrally planned economy, the disadvantages include lack of competition, inefficiency in resource allocation, slow innovation, and limited consumer choice.
Some of the disadvantages of centralization is the resources are concentrated to the center and do not reach the grassroots, it leads to delay of work, and has no secrecy or loyalty. The disadvantages of decentralization is that work allocation and performance evaluation is not uniform.

Because the C programming language leaves the responsibility for memory allocation and pointers entirely with the programmer, the disadvantage of linked lists over some other linear data structures (such as arrays) is that the bear a risk or memory leaks and invalid pointers. The fact that the size of a linked list is generally not deterministic is also commonly viewed a disadvantage over statically linked linear containers (e.g. arrays) in some systems, primarily in embedded systems. Compared to containers of higher order (such as trees or hash tables), search operations in a linked list are generally slower. Compared to a double linked list, removal and insertion of items (except head and tail) is generally more expensive.
