The difference between chain storage structure and sequential storage structure

The difference between chain storage structure and sequential storage structure: 1. Sequential storage needs to open up a fixed-length space and has fast read and write speeds. Its disadvantage is that it cannot be expanded; 2. Chain storage does not need to worry about capacity issues. , the reading and writing speed is relatively slow. Since the address of the next data needs to be stored, the storage space required is larger than that of sequential storage.

Difference:

1. Sequential storage needs to open up a fixed-length space, and the reading and writing speed is fast. Disadvantages Unexpandable (if you want to expand, you need to open up a new space large enough to rewrite the original data).

2. Chain storage does not need to worry about capacity issues. The read and write speed is relatively slow. Since the address of the next data needs to be stored, it requires larger storage space than sequential storage.

1. Introduction to chain storage structure:

Chain storage structure is also called linked storage structure. A set of arbitrary storage units is used in the computer to store the data elements of the linear table (this set of storage units can be continuous or discontinuous).

2. Sequential storage structure:

Sequential storage structure is one of the storage structure types. This structure stores logically adjacent nodes in physically adjacent storage locations. In a unit, the logical relationship between nodes is reflected by the adjacency relationship of the storage unit.
