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 DataO Step 2:Capture DataO Step 3: Manipulate DataO Step 4: Output ResultsO 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
