The Computing Revolution
 
Distant Pre-history (prior to 1945)
 
Birth of “Digital” Computers around WWII
 
Repeated revolutions since then with
computing technology becoming pervasive

We will examine what that is
and what its implications are

The Software Revolution
 
Relatively few people actually 
program
computers.  Most use software (programs)
developed by others, intended to be used by
people with limited understanding of how
computers work, hence a huge market in
commecial computer appications
 
E.g., spreadsheets, accounting, databases,
powerPoint, word processing, web design, games,
mathlab, computer aided design, graphics,
imaging, simulation
 
The Communications and Multimedia
Revolution
 
 
The Internet (email, world wide web, file
transfers, messaging, mobile computing, etc)
 
The convergence of Computers, TV, Telephone,
Multi-Media, Personal Digital Assistants that now
communicate with each other in increasing
numbers using a wide variety of media (images,
video, sound, text, etc.)
 
     All made possible due to Moore

Law
Law
 
The number of transistors that can be manufactured
into a square inch of an integrated circuit doubles
every 18 months or so.  This means:
 
The amount of memory that can be supplied for a
given cost doubles every 18 months or so and,
The speed of computation goes up by a factor of 2
about every 1.5 years for the same cost!
 
   
Gordon Moore, co-founder Intel Corp
       
made this observation 60 years ago!
Implications of Moore
s Law
 
The Apple iPhone would have needed more space
than this room 40 years ago!
 
The equivalent amount of memory and
computing power in your average PC would have
cost >$3M 25 years ago!
 
A miniaturized computing device today can fit on
a chip small enough to be injected into your
blood stream and perform a diagnostics on your
heart and send the results back using a wireless
network.
 
Moore
s law in action
 
 
 
The Emergence of a New 
Law
 
Bandwidth
 (the amount of information one can
pump though a connection) doubles every nine
months or so.
 
Interestingly, it seems that the amount of
information we want to send doubles at the same
rate, due in large part to the growth and
commercialization of the internet.
 
 
 
 
 
 
Bits ( = Binary Digits)
 
Internally, all data in a digital device is stored in electronic
devices that are either on or off (binary).
 
These devices are made from electrical components called
transistors.
 
Thus all data can be thought of as being expressed in 
bits
,
where each bit is either on = 1 or off = 0. 
(also expressed as
true/false)
   In future lectures we will understand how using large
numbers of bits, data can be stored and manipulated in a
binary system at incredible speeds
 
 
Analog to Digital Conversion….How does it work?
 
Sound around the world with the click of the
mouse!
 
Analogue-to-digital conversion ...

In this course, you will gain insight into how all of this works!
 
Inside the machine the binary
looks something like this…

The Digital (Re)-Evolution
Some Examples
 
Digital Documents(Email, E-Books, Presentations)
Digital Music (CD, Streaming, Downloading)
Digital Imaging (CMOS Imagers)
Digital Video (DVD, Streaming)
Digital Television (HDTV)
Digital Communications (Internet, Wireless)
Digital Signatures and Identities!!!
Digital Money (Crypto Currency)
Digital Art  (Non Fungible Tokens)
 
Where Does This Flexibility Come From?
 
 
All data that the computer will work on, and the
instructions it will execute (the software) , are
stored in electronic digital memory in binary
format.
 
Thus the same physical device, but loaded with
different instructions and data, acts quite
differently.
 
Each “App” is in effect a different and unique
combination of 1’s and 0’s that the machine
knows how to interpret
In Other Words
,
 
Digital representation of information
    
 is now the norm
 
Affects practically every aspect of modern
life
 
Similar to Medicine, advancements
continue to occur at an ever quickening
pace

Summary
 
Today
s digital and computer systems are far
more than computational and text processing
tools
 
They enable a new communication paradigm
 
This paradigm is enhanced by the rapid
expansion of the Internet and the applications
that ride on it
 
It pervades society and everyday life in ways
that we rarely appreciate or think about
 
In CS2 we will examine this phenomena from
many aspects and give you useful tools that
help you master it!
