What is the difference between chain storage structure and sequential storage structure

Xiaobian to share with you what the difference between chain storage structure and sequential storage structure, I hope you have something to gain after reading this article, let's discuss it together!

The difference between chain storage structure and sequential storage structure: 1, sequential storage needs to open up a fixed length of space, read and write speed is fast, its disadvantage is that it cannot be expanded;2, chain storage does not need to worry about capacity problems, read and write speed is relatively slow, due to the need to store the address of the next data, so the storage space required is larger than sequential storage.

Difference:

1, sequential storage needs to open up a fixed length of space, read and write speed is fast, the shortcomings can not be expanded (if you want to expand the need to open a new large enough space to rewrite the original data).

Chain storage does not need to worry about capacity problems, read and write speed is relatively slow, because to store the address of the next data, the storage space required is larger than sequential storage.

I. Introduction to Chain Storage Structure:

Chain storage structure, also known as linked storage structure. In a computer, an arbitrary set of storage locations (either contiguous or discontinuous) is used to store the data elements of a linear table.

II. Sequential storage structure:

Sequential storage structure is one of the storage structure types. This structure stores logically adjacent nodes in physically adjacent storage units, and the logical relationship between nodes is reflected by the adjacency relationship of storage units.

After reading this article, I believe you have a certain understanding of "what is the difference between chain storage structure and sequential storage structure". If you want to know more about it, please pay attention to the industry information channel. Thank you for reading!
