Introduction To Binary Trees

A binary tree is a hierarchical data structure in which each node has at most two children generally referred as left child and right child.
Each node contains three components:
  1. Pointer to left subtree
  2. Pointer to right subtree
  3. Data element
The topmost node in the tree is called the root. An empty tree is represented by NULL pointer.
A representation of binary tree is shown:
Binary Trees

Common Terminologies

  • Root: Topmost node in a tree.
  • Parent: Every node (excluding a root) in a tree is connected by a directed edge from exactly one other node. This node is called a parent.
  • Child: A node directly connected to another node when moving away from the root.
  • Leaf/External node: Node with no children.
  • Internal node: Node with atleast one children.
  • Depth of a node: Number of edges from root to the node.
  • Height of a node: Number of edges from the node to the deepest leaf. Height of the tree is the height of the root.
Binary Trees

In the above binary tree we see that root node is A. The tree has 10 nodes with 5 internal nodes, i.e, A,B,C,E,G and 5 external nodes, i.e, D,F,H,I,J. The height of the tree is 3. B is the parent of D and Ewhile D and E are children of B.

Advantages of Trees

Trees are so useful and frequently used, because they have some very serious advantages:
  • Trees reflect structural relationships in the data.
  • Trees are used to represent hierarchies.
  • Trees provide an efficient insertion and searching.
  • Trees are very flexible data, allowing to move subtrees around with minumum effort.

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,...

INTRODUCTION OF DBMS

-
What is Database :- The database is a collection of inter-related data which is used to retrieve, insert and delete the data efficiently. It is also used to organize the data in the form of a table, schema, views, and reports, etc. For example: The college Database organizes the data about the admin, staff, students and faculty etc. Using the database, you can easily retrieve, insert, and delete the information. DBMS (Database Management System):- Database management system is a software which is used to manage the database. For example: MySQL, Oracle, etc are a very popular commercial database which is used in different applications.DBMS provides an interface to perform various operations like database creation, storing data in it, updating data, creating a table in the database and a lot more.It provides protection and security to the database. In the case of multiple users, it also maintains data consistency. DBMS allows users the following tasks:- Data Definitio...

Introduction to cache memory

Cache Memory in Computer Organization Cache Memory  is a special very high-speed memory. It is used to speed up and synchronizing with high-speed CPU. Cache memory is costlier than main memory or disk memory but economical than CPU registers. Cache memory is an extremely fast memory type that acts as a buffer between RAM and the CPU. It holds frequently requested data and instructions so that they are immediately available to the CPU when needed. Cache memory is used to reduce the average time to access data from the Main memory. The cache is a smaller and faster memory which stores copies of the data from frequently used main memory locations. There are various different independent caches in a CPU, which stored instruction and data. Levels of memory: Level 1 or Register – It is a type of memory in which data is stored and accepted that are immediately stored in CPU. Most commonly used register is accumulator, Program counter, address register etc. Level 2 or...
