TAILIEUCHUNG - Lecture Discrete structures: Chapter 1 - Amer Rasheed

Lecture 1 - Introduction. The following will be discussed in this course: Discrete vs continuous, what is discrete structures? Applications of discrete mathematics, logic, elementary number theory and methods of proof, set theory, relations, sequences and recursion, mathematical induction, counting, relations and equivalence relations, graphs, trees. | (CSC 102) Dr. Amer Rasheed COMSATS Institute of Information Technology Discrete Structures Discrete vs Continuous Examples of discrete Data Number of boys in the class. Number of candies in a packet. Number of suitcases lost by an airline. Examples of continuous Data Height of a person. Time in a race. Distance traveled by a car. What is discrete Structures? Discrete mathematics is the part of mathematics devoted to the study of discrete objects (Kenneth H. Rosen, 6th edition). Discrete mathematics is the study of mathematical structures that are fundamentally discrete rather than continuous (wikipedia). Applications of discrete mathematics How can a circuit that adds two integers be designed? How many ways are there to choose a valid password on a computer? What is the shortest path between two cities using transportation system? How can I encrypt a message so that no unintended recipient can read it? How many valid internet addresses are there? How can a list of integers be sorted so that the integers are in increasing order?
