  1. Capabilities of ICT Advantages & capabilities… what ICT can do…

  2. Capabilities of ICT • Speed of access: access to results – queries, calculations… • Speed of response: feedback - fast processors – computer control/monitoring… Car? Plane? • Optimum performance: stock maintenance, throughput of cars on a production line, bank transactions • Guaranteed results – same quality throughout

  3. Capabilities of ICT • Smaller • Increased storage capacity • Faster processing • Accessibility e.g. voice recognition • What about the future? • Look at the past first…

  4. ICT – a quick look back • The first integrated circuit was invented by Jack Kilby in 1958. • The first computers using integrated circuits were built in 1967.  • In 1971, INTEL developed the first Microprocessor • The floppy disk was also developed in 1971.  • 1975 saw the introduction of the IBM 5100, the 1st mass-produced personal computer. • In 1975, both the Microsoft Corporation and the Apple Corporation were founded.

  5. ICT – a quick look back • Microsoft introduced MS-DOS version 1.0 in 1981, the same year that IBM introduced the first IBM "PC" personal computer. • The term "hackers" was introduced in 1985. • In 1985, Microsoft introduced their first version of Windows. • In 1985, Intel introduced the 386 microprocessor. The 486 microprocessor was introduced in 1989, the 586 Pentium microprocessor in 1992, the Pentium Pro (X86) was introduced in 1996, the Pentium II in 1997, the Pentium III in 1999, and, most recently, the Pentium IV in 2001.

  6. ICT – a quick look back • BGS 1980 … our first computer was a Commodore “Pet” • 16k or 32k memory! • Save work on tape • Later versions and disk support (100k) • BASIC was the programming language used – very easy to program!

  7. ICT – a quick look back • Then we added some Commodore Vic 20s and Commodore 64s… • More memory! Colour too! • Connect to your TV (!) • 1984…

  8. ICT – a quick look back • 16k to 48k memory • 128k memory later • Colour via TV • Printers available (printing on thermal paper 10cm wide!) • 1982 - 1988

  9. ICT – a quick look back • The BBC computer • 32k memory • Save to tape or disk drive (100k) • Later… network developed (Econet) to connect to a “file store” (server)… 20 Mb HDD! • 1981 - 1986

  10. ICT – a quick look back • RM Nimbus computer • 8086 processor! • Windows! • Almost looked like a real computer • (Did have a monitor) • Networked • 1985 -

  11. ICT – a quick look back • 1990s – DAN computers • 16Mb RAM, 100Mb HDD, 486 processors at 33Mhz, networked • 1996 – Dotlink computers • 32Mb RAM, 500Mb HDD, Pentium processors at 166Mhz, networked • 2000 – 128Mb RAM, 10Gb HDD, Pentium III at 500 Mhz, networked • 2003 – 512Mb RAM, 40Gb HDD, Pentium IV… at 3Ghz? …, networked (cable & wireless)

  12. And now… + =

  13. And now… • Tablet PC… • Future?
