Python chapter 1 Hello, World TECH KNOWLEDGE MASTER, What you should know You should know how to edit programs in a text editor or IDLE, save the file and run the file once the files have been saved to your disk. Printing Programming tutorials since the beginning of time have started with a little program called "Hello, World! The syntax changed in Python 3.0.

It has the ability to store, retrieve, and process data. You probably already know that you can use a computer to type documents, send email, play games, and browse the Web. You can also use it to edit or create spreadsheets, presentations, and even videos. => The computer as we know it today had its beginning with a 19th century English mathematics professor name Charles Babbage (Father of Computer). He designed the Analytical Engine and it was this design that the basic framework of the computers of today are based on. => Generally speaking, computers can be classified into 5 Generations. Each generation lasted for a certain period of time, and each gave us either a new and improved computer or an improvement to the existing computer. 1. First Generation (1936-1956) Vacuum Tubes a.  In 1937 the first electronic

Introduction of computer :      The year of 20 and 21st century has witnessed rapid developments in science and technology influencing every aspect of human life. One of the greatest things that man has ever created is, perhaps, 'the Computer'. The computer is truly an amazing machine. Computer is being used in areas of administration, medicine, education, sports, defence, shops, home, markets and many more. Computer and Information Technology (IT), in recent years, has become an integral part of our life. We can see it almost everywhere.     A computer is an electronic machine that helps to process data. It is used to solve problems relating to almost all fields such as education, home, medicine, science and technology, research, designing, publishing, communication etc.       A computer is an information-processing and information-accessing tool. This means that a computer accepts some information or data from the outside world. It processes it to produce a new
