Conclusion 1.3 (Introduction)

Finally I am presenting you the first conclusion about the first chapter. Have fun and comment what could be better;)

The first chapter gives us a overview all topics in the book but mor technical than the chapter before ("Conclusion 2.1" about the foreword). At first it decides between

-Manual data processing (Without tools or something like pen and paper.)

-Mechanical data processing (With tools like mechanical typewriter or something other mechanical)

-Electrical data processing (Uses tools that are electrical like electrical typewriter or something else)

-Electronic data processing (Means to use electronical recources like computers.)

After that we get an overview about the different fields of computer science which includes the theoretical, technical, practical & applied fields. I will describe that in another post! If it is already uploaded you can read the post "here".

Now chapter one get out the common path and describes regional differents between apprenticeships studies and so on. Which are very interresting and important for me because I was born and life in germany until that post but I am going to spare you that.

After that the author writes something about the story of the computers. From abacus & the introduction of the "place value system" or the "positional nation system" to the modern computer. Names that you should know if you are interested in that are (If there are important dates or topics named in the chapter I added them): 1. Mohamed Ibn Musa Al-Chwarizmi

2. Blaise Pascal (adding machine)

3. Gottfried Wilhelm Leibniz (1690)

4. Charles Babbage (differential engine analytical engine)

5. "Ada Lovelace"

6. Konrad Zuse (Z1, Z2, Z3)

7. John von Neumann

8. Bill Gates

9. John Warnock

10. Steve Jobs

11. Clive Sinclair

12. Dennis Ritchie & Brian Kernighan

13. Bjarne Stroustrup

14. Noam Chomsky

Know we know the most important people that invented or created something, like a Computer, a programming language or something else. next we will differentiate between a electrical, electromechanical and electronic. At first electrical is if some mechanical parts are controled by electric. electromechanical in the other hand is something that will be controled by an elctromagnet and is a switching element.

The generations of computer will be cut of into 4 different generations.

Generation 1: "Tube calculator"

Generation 2: "transistor calculator"

Generation 3: "Calculator with integrated circuts"

Generation 4: "Calculator with micro processor"

I'll hope you enjoyed the first conclusion about the first real chapter of this book. I did.

In this chapter was also the talk about different kinds of computer languages but that is something that will be also posted in a different post. I'll hope you keep healthy and have a nice rest of the week.
