Interesting Facts

• In the 1770’s a Pierre Jaquet-Droz, a Swiss watchmaker, created some mechanical dolls and called them as automata.
• These dolls could read instructions and thereby considered programmable.
• These dolls could play music and write letters
• Charles Babbage also wanted to build a computer which is programmable and can perform analytical operations
• Charles Babbage (1833) met Ada Lovelace, She became very impressed in Babbage’s plan and she wrote notes outlining her ideas for Babbage’s Analytical Engine on how to be programmed.
• We can call her the inventor of programming.

What is a Program?

• A computer is dumb, in the sense that , without programs it can not do any thing.

• Program is set of instructions which the computer executes

• We are here to learn how to write these programs using Python so that computer can run our applications.

• The System Architecture

• We as programmers will write the user applications or make our application work on existing user applications

• Lets assume we are building an application for resume creation

  • Our application has to work on top of os
  • OS will create a Process in which our application runs
  • The code which we have written has to be executed by CPU and Process will be given some cpu cycles.
  • To remember the values used during the application Process will be given some memory (RAM)
  • Our application has to generate a word document for this our application will use disk through OS Kernel

• To make it easy to write applications we have programming languages (Python, Java, C, C#, Ruby…)

  • Understand the memory aspects
  • Understand the program execution process
  • Algorithms and Psuedo Code
  • Writing programs
