Detailed explanation-1: -A data structure is a specialized format for organizing, processing, retrieving and storing data. There are several basic and advanced types of data structures, all designed to arrange data to suit a specific purpose. Data structures make it easy for users to access and work with the data they need in appropriate ways.
Detailed explanation-2: -Arrays make it possible to organize data in an efficient manner because the indices make it possible to retrieve any element. They are relatively easy to implement. However, all the elements have to be of the same type, and searching through a large array can be time consuming if it is not sorted.
Detailed explanation-3: -The most frequently used data structures for one-dimensional database indexes are dynamic tree-structured indexes such as B/B+-Trees and hash-based indexes using ex-tendible and linear hashing.
Detailed explanation-4: -Which data structure is used to store information about a process? Explanation: A process control block is a data structure which is used for storing information about a process. It is also known as task control block and is maintained by the kernel for maintenance of a process. Each process has its own pcb.
