Arrays and linked lists are data storage facilities that can store data of similar types. Since both have a similar type of function, we use them differently in different situations. Going by the arrays and linked lists book should learn to identify the need for arrays or linked lists in different data storage situations. Since both arrays and linked lists are themselves a data storage topic, we will discuss their functions, and advantages and disadvantages in the coming section. Arrays and linked lists GATE questions come in many exams, including CAT, GATE CS, PDU CS, SDE interviews, and more. Arrays and linked lists online tests also form a part of various state and national level exams.
The data structure is a broad topic and has a vast syllabus. The major topics for arrays and linked lists study material for GATE CS is given below. We will check on some major differences between the arrays and linked lists.
Collection of similar types of independent elements.
Collection of similar types of elements connected with each other by pointers.
We can randomly access the elements of the array from any side.
We can online access the elements sequentially as random accessing is not allowed in case of pointers.
The following are some tips that you can follow while solving arrays and linked lists questions. Prepare for the topic by solving previous years’ question papers well.
Here's why the tree is an integral part of the GATE and other competitive exams:
The following are some excellent books of arrays and linked lists for computer science that can help you prepare for the arrays and linked lists syllabus for GATE CS.

Q. What is an array?
Arrays are the linear data storage places allocated in the memory to store similar types of data elements
Q. What is the importance of a linked list?
Linked lists are not fixed, and elements can be stored anywhere in the memory. It ensures that adding new elements is not as expensive, as it doesn't require creating a new memory.
Q. Which of the following has better cache locality: Arrays or Linked Lists?
Arrays have better cache locality from the given options, making a huge difference in the program performance
Q. Which operations can be performed easily on the linked lists?
Compared to arrays, the operations such as INSERT and DELETE can be performed easily on the linked lists as they save time.
Q. How can linked lists provide storage anywhere in the memory space?
Linked lists use pointers that reference the pointed element back to their source address.
