Course Objective O This course focuses on a breadth-first coverage of computer science discipline, introducing computing environments, general application software, basic computing hardware, operating systems, desktop publishing, Internet, software applications and tools and computer usage concepts; Introducing Software engineering and Information technology within the broader domain of computing, Social issues of computing

Computer: Definition (1/2) O The word computer comes from the word “compute”, which means, “to calculate” O Thereby, a computer is an electronic device that can perform arithmetic operations at high speed O A computer is also called a data processor because it can store, process, and retrieve data whenever desired

Computer: Definition (2/2) O The activity of processing data using a computer is called data processing O Step:1 Data O Step 2:Capture Data O Step 3: Manipulate Data O Step 4: Output Results O Step 5: Information O Data is raw material used as input and information is processed data obtained as output of data processing

Evolution of Computers (1/2) O Blaise Pascal invented the first mechanical adding machine in 1642 O Baron Gottfried Wilhelm von Leibniz invented the first calculator for multiplication in 1671 O Keyboard machines originated in the United States around 1880 O Around 1880, Herman Hollerith came up with the concept of punched cards that were extensively used as input media until late 1970s

Evolution of Computers (2/2) O Charles Babbage is considered to be the father of modern digital computers O He designed “Difference Engine” in 1822 O He designed a fully automatic analytical engine in 1842 for performing basic arithmetic functions O His efforts established a number of principles that are fundamental to the design of any digital computer
