Transcript The History of Computers

When these machines weren’t so simple
and we had to run our own lives.
In this presentation, I will bring you back.
When I mean back, I only mean about 20 or so
years, because that’s when computers started
to be produced and used. I will go over how
simple they were, and show you:
O 1st – 3rd Generation Computers
O Early computer’s basic functions and
abilities
O Early Computer Specs and computer
languages
O Early (and current) Computer Companies
O And maybe the extra tid-bit or so.
But before we had computers, we had special
instruments that helped us make these complex
calculations on own.
O The Abacus
O Difference Engine
O Antikythera
O Slide Rule
There are more, but
these are come of the
few basic ancestors
that came up first.
Computer Generations
1st – 3rd Generation computers
1st Generation Computers
O These huge beasts were made up mostly of vacuum
O
O
O
O
O
tubes
Because of this, they over-heated often
They took up an entire room for just 1 of them!
They could only perform the simplest of calculations
Examples of some of the giant machines were the
Aniac, the Mk1, the Univac, and the Csyrac.
Some of the specs for one of these machines in
Australia was .001 MHz and 2kb of Ram. Not even a
penny’s worth compared to today’s PC’s.
2nd Generation Computers
O Transistors, a small
semiconductor
device, made these
new machines:
O Smaller
O Faster
O Cheaper
3rd Generation Computers
O Silicon chips were
produced at this
time, which brought
about a very
important computer
technology.
O Computer
Networking.
But, what does a computer
Do?
O I’ve told you what the computers are. But what do
O
O
O
O
O
O
they do?
Computer were built to make simple calculation
originally, but as time passed, they gained more
purpose.
Finding Information
Communication
Information Storage
Entertainment
All in all, making life easier.
O And in order for a computer to do these
O
O
O
O
things, it needed some way to communicate
with itself. So, we made computer
languages.
Cobal
Basic
4Tran
And by now, probably many more that we
could never hope to understand without a
working knowledge of computers.
Todays Computers, and
Who Made them.
I think we’ve had enough talk about the old days. Let’s
bring in something new! (Well, not completely.)
The Two known Computer
Companies.
Microsoft
O These are known to
be the two competing
companies in
computer production
O But what you don’t
know is that they
both started out from
a company called
Apple
IBM, the creator of the
PC.
O (PC Meaning
Personal Computer,
and the release of
computers to the
public.)
And now we have today’s computers,
which are mostly transportable.
O This is the technology of our
era, and it has actually has
come a long way from what
there was. (Not in time’s
length, however.)
O This is what we have today,
but in the future, who knows
what kinds of computer we
will have? Maybe we won’t
even need a console to use
one!
But now, the history of computers is
completely up to us. Maybe you will inspire it’s
next great leap!
But for now, we have what we have. And I can’t really tell
you any more, You are going to need to figure that out
for yourself.
Make History.
