Introduction to Linked Lists

Linked List is a very commonly used linear data structure which consists of group of nodes in a sequence.
Each node holds its own data and the address of the next node hence forming a chain like structure.
Linked Lists are used to create trees and graphs.
Linear Linked List

Advantages of Linked Lists

  • They are a dynamic in nature which allocates the memory when required.
  • Insertion and deletion operations can be easily implemented.
  • Stacks and queues can be easily executed.
  • Linked List reduces the access time.

Disadvantages of Linked Lists

  • The memory is wasted as pointers require extra memory for storage.
  • No element can be accessed randomly; it has to access each node sequentially.
  • Reverse Traversing is difficult in linked list.

Applications of Linked Lists

  • Linked lists are used to implement stacks, queues, graphs, etc.
  • Linked lists let you insert elements at the beginning and end of the list.
  • In Linked Lists we don't need to know the size in advance.

INTRODUCTION Digital computer concept:- 1. Digital computers are designed to store, process and communicate information in digital form. 2. Digital computer is any of a class of digital devices capable of solving problems by processing information in discrete form. 3. It is used for processing data represented by discrete, localized physica signals, as the presence or electic current. 4.The main three components of digital computer:- >input:- The user gives a set of input data through input devices. >Processing :- The input data is processed with the help of CPU by well defined and finite sequence of step. >Output : - Some data available from the processing step are output to the user. TYPE OF DIGITAL COMPUTER :- 1.Microcomputer/Desktop computer 2.Minicomputer 3.Mainframe computer 4.Supercomputers Microcomputer :- 1.Microcomputer is also called a personal computer or desktop computer. 2.It includes a microprocessor, memory, and

There are 195 countries in the  world, some are developed countries, some are undeveloped , and some are underdeveloped or developing countries . The distinction between them is a different process but we can differentiate based on conditions like economic growth , GDP, employment rate , population, etc. Let's understand how we can say whether the country is developed. ADVANCE OR DEVELOPED ECONOMIES An advanced or developed economy is one, which carries on production with a large amount of machinery and advanced techniques. An advanced economy employs its human and other resources to the maximum extent possible.  The productive efficiency of a developed economy is of a very high order, and the per capita income is also high. Consequently, people in these countries enjoy high standards of living.  England, the U.S.A, France, west Germany, etc, are advanced economies. These economies are inhabited by over one-fourth of the entire population of the world. ADVANCED ECONOMY Advanced Ec
