Informatica

by G. Michael Schneider, Judith L. Gersting

Questo libro parte dal presupposto che l'informatica sia una disciplina scientifica di base, al pari della fisica o della matematica, e che come tale debba essere insegnata in ambito universitario. Il testo, quindi, non si limita a descrivere un insieme di tecnologie centrate sul personal computer, né tanto meno fornisce le istruzioni per l'utilizzo di uno specifico pacchetto software; piuttosto, gli autori puntano a chiarire i fondamenti concettuali dell'informatica intesa come "scienza degli algoritmi". L'esposizione procede per livelli successivi. Il livello di base è costituito dallo studio delle proprietà formali e matematiche degli algoritmi; nei livelli successivi si affrontano l'implementazione degli algoritmi in appositi dispositivi hardware e nella "macchina virtuale" creata dal sistema operativo; la loro traduzione in appositi linguaggi di programmazione; infine il loro impiego in applicazioni di particolare rilevanza pratica, che stanno modificando profondamente la nostra vita quotidiana, aprendoci nuove opportunità e, allo stesso tempo, ponendoci nuove sfide in ambito etico, giuridico e sociale.

Excellent section on computer ethics. Thought this was a very solid textbook. I'd consider keeping it if I still gave a crap about computers.

I learned computer science!

Excellent introductory book to computer science. After learning the bases of code I wanted to dive deeper in what is the essence of a computer, so I decided one of the ways was to read a textbook about introduction to computer science. I got exactly what I wanted. From the basics of how transistors work to the software world, this book describes each step of what a computer is and how it works. It doesn't go deep into each topic but it touches a lot of them with clear explanations, and this is what we look for in an introductory book.

From algorithms to ethics and every bit and transistor in between. A little too indepth and boring in places but overall a solid intro to CS.

Yea I enjoyed it so what

Good book to get a better understanding of Computer Science and computers. This book is structured in such a way that it takes you through all layers of computer science by starting at 'Algorithmns and Foundations' through to the 'Social Issues' of computers and computer science. (Note: this book is merely an introduction into the computer science field, therefore no programming is taught)

Great for a textbook.
