The document provides a chronological overview of the history of computers from the 1940s to the 2010s. Some of the early milestones included the creation of the Z3 computer in 1941, the ABC in 1942, and the ENIAC in 1946. Major developments in the 1960s included the CDC 6600 and IBM System/360. The 1970s saw the release of the floppy disk and C programming language. The personal computer era began in the 1980s and 1990s with products like the Macintosh, Windows 3.0, and the World Wide Web being introduced. New devices launched in the 2000s and 2010s included the iPad, Xbox One, and Apple Watch.

IT Fundamentals

2. The first computer
• In 1941, the z3 computer was created by an engineer fromGermany known
as Konrad Zuse.The Z3 can perform floating point binary arithmetic, and
has a 22 bit word length. However it was destroyed by a bombing raid in
1943.

3. 1942
• In 1942, the Atanasoff-Berry Computer or ABC for short is created by
Professor JohnVincent Atanasoff and Student Clifford Berry.

4. 1946
• Started in 1943 but unveiled in 1946, the ENIAC was created by John
Mauchly and J. Presper Eckert.This computer was used for programming
occupied over 1,000 square feet and weighed thirty tons.

5. 1948
• In 1949, NorbertWiener writes a book called Cybernetics, which contributes
to Artificial Intelligence orAI and control systems.

6. 1949
• In 1949 the EDSAC is completed by MauriceWilkes.This computer could
perform common repetitive calculations.
• EDSAC stands for Electronic Delay Storage Automatic Calculator.
• The MADDIDA was created to help with mathematical equations.

7. 1950
• In 1950, the SEAC and the SWAC were completed to be the first stored-
program computers.

8. 1961
• In 1961, the military started to use computers to continuously calculate their
position in flight.

9. 1962
• In 1962,Tom Kilburn an his team permitted a computer to use its storage
capacity

10. 1964
• In 1964, three computers were introduced, let’s take a look:
• The CDC 6600 performs up to 3 million instructions per second.The speed came from the
computers design which used 10 mini computers to offload the workload from the cpu (central
processing unit).
• The PDP-8 was designed by Gordon bell and Edson de Castro.This became the first
commercially successful minicomputer and sold for 18,000 dollars.
• IBM released the System/360 on April 7, and it became a major event in the history of computer.
All the models could run the same software and had a 50-to-1 performance range.

11. The rest of the 1960s
• The 3c DDP-116 was introduced as a general purpose computer that costed
28,500.
• The 2116A was HP’s first computer and was HP’s first recorded use of
integrated circuits in a commercial product.

12. The 1970s
• IBM released a read/write floppy disk .This became an industry standard.
• The pascal programming language was presented by Professor Niklaus
Wirth.This language is applicable to both commercial and scientific
applications.
• The C programming language is released by Dennis Ritchie and his team. C
is one language in programming being used today.
• The first computer installed in the white house was a XeroxAlto.

13. The 1980s
• The Sinclair ZX80 was introduced in Britain for 79 pounds.
• The first CD was released in 1983, and this game-changer still plays a role in
todays world.
• The C++ language by Bjarne Stroustrup.This is an important language in
today’s world as many people use it.
• The Macintosh was introduced.This was a failure and was shut down soon.
• Nintendo releases the Gameboy.

14. The 1990s
• Windows 3.0 is released by Microsoft.This was the first windows to really satisfy PC
users.
• Photoshop is released by brothers John andThomas Knoll.
• The world-wide-web (www) is introduced by CERN.
• Java 1.0 is made by sun microsystems.
• The first PlayStation is Released.
• Wi-Fi is available at home for the first time.

15. The 2000s
• The USB drive, and a camera with a phone is released.
• The first XBOX is released.
• Windows XP is released.
• Blue-ray discs and the PowerMac G5 are released.

16. The 2010’s
• The iPad is released by apple in 2010.
• Office 365 is released
• The ps4 and Xbox one are released.
• The apple watch is introduced.
