These days we take the world of
computing for granted, using it in almost every aspect of our lives; emails,
streaming, social media, at work and so on. The question is do we really know
where this technology came from? Do you know who invented the first computer or
the first modern computer? Is there a difference between the two? Now let’s
find out here.
A computer is defined as an
electronic device capable of receiving information and performing a sequence of
operations predetermined by a program to produce a result as information or
signals. The original computers weren’t anywhere near the likes of the Apple,
HP or Dell devices we’re all used to, they were huge mechanically driven
juggernauts utilizing relays, telephone equipment and vacuum tubes.
Most of the original computer concepts were used during World War II. The most
famous being the Bombe created by Alan Turing, used to help decipher German Enigma
codes.
Here we’re going to focus on
the PC, the version of the computer we all know best, as well as the main
developments in technology that affected it. The PC, or Personal Computer, was
a massive leap for technology and it was all due to the development of the
first microprocessor which allowed machines to be sold at a much lower cost and
effectively made them consumer goods. The term PC covers a broad range of areas
including, desktop, laptop or tablet. This is nowhere near a complete list but
here is a timeline of the significant PCs and technologies;
1977 – The first wave of home computers, ‘The
Trinity’ as dubbed by Byte Magazine. These were the TRS-80 selling over 10,000
in the first month which had, hence the name, a Z80 microprocessor. The Commodore
PET used the newly marketed MOS 6502 microprocessor and was quickly beaten by
the Apple II due to its high color graphics and it even came with the game
‘Breakout’ on cassette as standard. All these offered 4KB or 8KB of RAM,
utilized BASIC programming language and cassette storage.
1978 – The 5 ¼” floppy disc was released, and
although there were previous versions, they were too expensive for the PC. The
5 ¼” was the most common form of PC data storage until the CD’s release.
1981 – The dawn of the laptop, or portables,
begins. In this year, both the Osborne 1 and Epson HX-20 were released. The
Osborne 1 weighed 24 pounds, had no battery and a 5″ CRT screen. The Epson had
a 120×32 pixel LCD screen, a small printer and a re-chargeable battery.
The IBM PC 5150 was, to many,
the PC they remember as the original. It had dual 5.25″ floppy disk drives,
64KB RAM and successful BIOS, so successful in fact that it led to a group of
new companies termed ‘IBM compatibles’, including Compaq, Dell and HP.
1982 – The Commodore 64 was the highest-selling
single personal computer ever, with over 20 million sold by 1994. In 1983 it
was selling as many units as every other computer combined due to its low cost
and availability in retail stores. This was also the year the first flip
style laptops appeared, including the GRiD Compass 1100 which cost over $8000
and was used mainly by NASA, the military and other organizations.
1983– This
was a big year for touch technology, The Gavilan SC was the first computer
advertised as a “laptop” and had the world’s first touch-pad. The HP-150, the
first home computer with touch screen technology, was also released. It
detected finger movements through a built-in grid of infrared beams across the
monitor’s front. However, the sensors collected dust and needed a lot
of cleaning. Touch technology would be a difficult concept to master with
many brands releasing their devices, all with their own issues, and
many chose to go for the simpler stylus system including Apple with their PDA,
the Newton many years later in 1993.
1984 – The reign of Apple continued
with the Macintosh, giving many their first look at a GUI or Graphical User
Interface, a vital part of any modern PC. Its supreme graphics were a result of
the MacPaint program. In this year, one of the biggest changes came for
computing, the CD-ROM, it was a few years until CD-R & RW’s came along but
the CD allowed for greater storage and easier data management.
1985 – Windows 1.0 was born, giving the GUI
interface of the Mac to Windows and stepping away from MS-DOS. It was quoted by
Gates as “unique software designed for the serious PC user” utilizing drop-down
menus, icons, scroll bars and information boxes as well as the much loved MS
Paint.
1988 – The Compaq SLT 286 was released and was
the first laptop to use VGA display commercially.
1990 – Windows NT was released; another GUI
style interface and an improvement on 1.0, sparking legal issues between
Microsoft and Apple about the way the software looked and felt.
Tim Berners-Lee also built the
World Wide Web in 1990, giving us the first look at the internet as we know it.
It included; HTTP – the most important internet protocol, HTML – a web
coding language and the first Web browser, web server, and Web pages describing
the project.
1994 – The
Apple Power Macintosh was released; a high-end PC aimed at digital media and
graphic designers and thus the bond was established. Also in this year,
Netscape’s browser was born and gave way to a new wave of people accessing the
web.
1995 – The operating system I remember the most
fondly, Windows 95 was launched and, due to its huge success, became the system
at the forefront for a long time. 95 was the first Windows OS with built-in
internet support, to use the plug and play concept and to feature the iconic
start button, taskbar and minimize/maximize and close options.
1998 – Google, everyone’s favorite search
engine, was created. Google brought for many the developments in web browsing
they needed and saw more people using the web.
1999 – Apple released its new iBook, the first
device to have a Wi-Fi slot for the new industry-standard wireless platform and
other brands quickly followed suit. Wi-Fi drastically improved home computing,
allowing connection wherever you were within its range, this meant PCs would
soon become common place in bedrooms and studies without the need for a cable.
2000 – The first USB flash drives were sold,
improving on data management again. However this wouldn’t be as quick a death
for the CD as they were for floppy disks.
2001 – The most popular OS of our time, Windows XP,
was released. XP became the standard to which all else aspired, it had numerous
versions in its life time and supported the latest in technology including
remote desktop, system restore and encrypting file system.
2002 – The Microsoft Tablet PC was, as the name
suggests, the first real PC style tablet. It used a stylus based touch-screen
and ran Windows XP tablet edition but due to their weight had little success.
This was also the year 1 billion PCs were officially sold.
2004 – A game-changing year for home computing.
Facebook was launched gaining over 1 billion users to date. Skype was also
released giving a simple and cheaper way of internet communication.
2005 – This year saw the death of the much loved
IBM as it sold itself to Lenovo. YouTube was launched in 2005 giving us all
infinitely more ways to procrastinate.
2006 – This year gave way to Microsoft’s biggest
failure, Windows Vista. Vista was supposed to be a huge success offering
Bitlocker drive encryption software for the first time, a more focused media
centre and a brand new look. However, it was far from a success with the press
and techy’s, myself included, branding it a failure. It was released
prematurely with numerous problems such as its limited amount of compatible
drivers.
2007 – Asus released the Eee, the first
ultra-portable laptop called Netbooks, a term coined by Intel. The Eee was a
huge success due to its small size, low cost and weight. It had a 4GB disk and
7” screen and gave way to a new wave of computing with many other brands
releasing their version.
In this year, Estonia gave the
world definitive proof of the significance of home computing when it carried
out a general election on the internet. Although not technically home
computing, in this year the Apple iPhone was released, and like the tablet saw
many people move away from their PCs.
2009 – Windows 7, even after all these years and
reinventions released, it’s still the option many companies go for. Windows 7
was built for the wireless age after Microsoft realized the success of laptops
and the need to connect on the go.
2010 – The Apple iPad, the most well-known
tablet of all, was born. With its 9.7” touch-screen display and the hordes of
apps available it soon became a huge hit with customers, and competitor Android based devices started flooding the
market.
2012 – The best of both worlds as it seems, the
Microsoft Surface with its detachable keyboard and kickstand allowed you to
have the convenience of a tablet with the usability of a laptop.
This was also the era of
Windows 8 with its touch-friendly app and tile interface. 8 was the first real
multi-platform software for use with touch devices and traditional PCs. It
featured the Windows Store, a marketplace for apps. Although a great system for
touch devices, it seemed to be less successful for the traditional PC, the
start button being the biggest complaint.
2013 – The Apple MacBook used the
revolutionizing Retina display technology which had 400 pixels-per-inch and was
crowned one of the slimmest laptops around.
2015 – Windows 10 has been released, a free to upgrade
OS seeing 75 million devices running 10 in the first month. Microsoft have
definitely pushed the boundaries and improved the system significantly,
offering a voice system similar to Apple’s Siri called Cortana, and the return of the
start bar meant many sceptics are more than happy to fall for Microsoft once
again.
So there we go, the first
computers were nothing more than glorified mechanical machines built mainly for
war-games. ‘The Trinity’ were the first leap forward, especially for Apple,
establishing the home pc and leading the way for the likes of the Commodore 64
and the Apple Macintosh which made the PC more affordable and introducing new
concepts like a GUI to the desktop world. The creation of laptops seemed to
spell the end of the home PC, users loved the portability of these devices
compared to the bulky desktop, and the tablet with its touch technology and
size was the final nail in the coffin for most customers. Every concept, from
the floppy disk to the flash drive, Windows 1.0 to 10, the Apple II to the Asus
Eee, revolutionized the way we use the PC and home computing in general. There
will always be a want for the new, the fast, the easy and the different and I
personally can’t wait to see what the future holds. In 2009, laptops officially
outsold desktop PCs and in 2013 tablets outsold both desktop PCs and laptops,
reaching over 200 million more units by 2016. So whatever device you’re reading
this on, remember where it came from, the originals, all pushing the boundaries
of what we know as the PC.
