The History of Computers
Atanasoff–Berry Computer
Although there were mechanical and electrical computers developed between 1833 and 1941, it wasn't until 1942 that the first fully electronic digital computing device was conceived.
The Atanasoff–Berry Computer (ABC) was not programmable and was only able to solve systems of linear equations.
Although limited to equations, the "ABC" pioneered computing elements such as binary arithmetic and electronic switching - elements still used in computers today.

1943 saw the creation of the first programmable digital electronic computing device, "Colussus".
This was to be the first program controlled computer designed by British engineer, Tommy Flowers.
It was designed during World War II and was used for the
code-breaking of German messages.
Programmable computers were to become the standard way of computing thereafter.

Ferranti Mark 1
Fast Forward
From the 1960s, computer and IT companies started to mold the personal computer into more user friendly models. They were capable of much more than just equations, designed to be interactive, display graphics and produce sound.
Companies like Hewlett Packard, IBM, Atari, Apple, Microsoft, Xerox, Commodore, Compaq and Dell brought us through the 80s, 90s and some are still going strong.
Today there are desktops, laptops, tablets, smart phones and games consoles to name a few.
They are as much a part of our daily lives now as toasters or televisions.
A Brief History of Computers
The history of computers is a fascinating and intriguing story.
Today, computers are fully incorporated into everyday living and their uses are vast and varied.
In the last century computers have been a crucial building block of modern day society and are still developing at an astounding rate.

Did you know?
The first recorded use of the word "computer" was in 1613 and referred to a person who performed computations or calculations.
It wasn't until the 19th century that the word started to refer to machines.
The Ferranti Mark 1 was the first commercially available general purpose electrical computer.
The first Ferranti machine arrived at the University of Manchester in February 1951.

The Ferranti just beat The UNIVAC I in the US.
The UNIVAC I ( UNIVersal Automatic Computer ) arrived in The United States Census Bureau one month later.

From here computers were becoming accessible to the masses.

Computer Software
Software advances have paralleled alongside computer technology and shaped how we communicate, create, store and present within our daily lives.
- Adobe photoshop has edited most of the media's images in magazines and posters
- Microsoft operating systems are used by the majority of PC users
- Oracle systems are the back bone of many companies and corporations

But where does the future of computing lie.......?

Did you know
The code behind [ctrl]+[alt]+[delete]
was written by David Bradley who worked for IBM.

He also shares the same name as the actor David Bradley who played Argus Filch the janitor in the Harry Potter movies.
Tech of Today
Google Glasses
The iRing
Virtual Reality Treadmill Game Controller
Future of Computing
The Virtual Reality Treadmill Game Controller, iRing and Google glasses are the leading tech of today and may change the course of our interaction with computers and the internet.

So What's Next
We as computing graduates are in the front line of this technology movement and may indeed be the next big name or great idea of the future.

We are all on a similar journey but our destination will be what defines us.
Computer Software Continued......
There are now amazing advances in motion sensor technology making our interaction with computers more realistic.
We are already on the way to 24/7 connectivity, so could we see a merging of reality and virtual becoming the norm?
Did you know ?
Future of Computing Continued....
All of these started as ideas, dreams or passions brought to life through hard work and determination by people like: Chuck Peddle, Bill Gates, Steve Wozniak, Steve Jobs, Mark Zuckerberg, Larry Page and Sergey Brin to name a few.

Future of Computing Continued......
We are now at a point of transition, like when mechanical computers developed into the electronic ABC computer and the Colussus, and from keyboards to mice and graphic tablets to touch screens.

I have a dream
My dreams
come true
Computer Software Continued......
With the production of apps and android software ruling today's marketplace alongside tablet / smartphones production, computing technology has become even more personal than the laptops and desktops of the noughties, but where or how else can it enhance our society?

The first hard disk drive,
was introduced by Seagate in 1979,
which could hold 5 M.B. of data.

So What's Next continued....
Indeed we might just be a smaller cog in the development of the industry,
but regardless of our role, we will be partaking on a fast moving, ever evolving technological journey.

Weather we take the front line or follow in the ranks, we all move together on this journey. A journey that for us starts here and now, our armor being the mistakes of others our weapons, ideas and dreams.

So What's Next Continued..........
Did you Know ?
Hewlett Packard
was first started in a garage
at Palo Alto in the year 1939.
While it took the radio 38 years and the television a short 13 years, it took the World Wide Web only 4 years to reach 50 million users.
