An Introduction to Computer Science and Problem Solving
Chapter 1 An Introduction to Computer Science and Problem Solving What is in This Chapter ? This first chapter explains what Computer Science is all about. It will help you understand that the goal of a Computer scientist is to solve problems using computers. You will see how problems are formulated by means of algorithms and how the process of abstraction can be used to break problems down to easily manageable pieces. Finally, we will discuss the notion of efficiency. COMP1405/1005 An Introduction to Computer Science and Problem Solving Fall 2011 - 2 - What is Computer Science ? Computers are used just about everywhere in our society: Communications: internet, e-mail, cell phones Word Processing: typing/printing documents Business Applications: accounting, spreadsheets Entertainment: games, multimedia applications Database Management: police records, stock market Engineering Applications: scientific analysis, simulations Manufacturing: CAD/CAM, robotics, assembly.
So, computer science is all about taking in information and then performing some computations & analysis to solve a particular problem or produce a desired result, which depends on the application at hand. Computer science is similar to mathematics in that both are used as a means of defining and solving some problem.
