Question

Write two features of each of doto structures:
1)  Record
2) Linear array 
3) Linked list 

Answer 1

1) Record : 
i) A record is as collection of relative data items, each of which is called as field or attribute.
ii) Collection of records is known as files. Collection of data is frequently organized into a hierarchy of fields, records and files. 
2)Linear array :
A linear array is the data structure which consists of finite ordered set of homogeneous data elements such that :
i) The elements of the array are reference respectively by an index set consisting on consecutive numbers.
ii) The elements of the array are stored respectively in successive memory locations.
iii) The number n of the elements is called length of size or array. 
3) Linked list :
i) A linked list if a linear of data elements called nodes where the linear order is maintained with the help  of pointers.
ii) Each node in the linked list is divided into two parts. First part is called as INFO part which contains the information about the element or actual element and second part is called as LINK part which is next pointer field e.g. it contains the address of next node in the list.
