Transcript of The Computer

The Computer
Impacts of the computer
Introduction
I am going to be looking at how the computer ended up being able to fit on a desk from a size of a room.
Commodore PET 4032
Apple Lisa
The Apple Lisa was introduced on January 1980.
It was the first commercial computer to have a graphical user interface and a mouse. The Lisa's CPU was a Motorola 68000 and had a speed of 5 MHz. It had a RAM of 1 MB.
The Apple Lisa was
unsuccessful

because it was expensive, there were not many software applications that were available and it was very slow.
Apple had to change the Apple Lisa because its floppy disks were unreliable. So they had to replace Apple Lisa owners with the new one. At first replacing the computer was free but then the owners had to pay $595.
Computer History

The first electronic and programmable computer was the Colossus.
The Colossus Computer

Colossus was demonstrated for the first time in December 1943. It was made to help read encrypted German messages during the Second World War.
It could do Boolean calculations. Boolean calculations are calculations that return true or false.
Colossus, the book written by B. Jack Copeland and others says that " the basic timing in Colossus was around 5 kilohertz (kHz), or 5000 cycles per second".

A computer is a programmable electronic device. It can run programmed instructions that may be pre-recorded.
The Definition of the Computer
Main PCs in history were
Manchester Baby Computer
The Manchester "Baby" was the nickname for the Small-Scale Experimental Machine. It was one of the first machines which contains everything that a computer has nowadays.
UNIVAC Computer
UNIVAC is short for Universal Automatic Computer and it was made in the USA.
IBM 701 EDPM Computer
The first commercially successful general-purpose computer.
Commodore PET 4032
The 40 in 4032 shows that there is a 40 character display and the 32 represents 32K RAM.
Apple Lisa Computer
Lisa stands for Local Integrated Software Architecture but it was also is the name of Steve Jobs' daughter. The Apple Lisa was the first commercial computer with a GUI. However the Apple Lisa was not popular.
Apple I
The Apple I was released by Apple in
July 1976. It was Apple 's first product and it was handmade by Steve Wozniak.

The CPU was a MOS 6502 @ 1 MHz. The memory was 4 KB but it could expanded to 8 Kb and 48 KB memory was achievable by using expansion cards.
40 years
The Commodore PET 4032 was introduced in May 1980. It was the newer and better version of the Commodore PET 2001. As mentioned before the number 4032 shows the PET's character display and RAM. The 40 in 4032 shows that there is a 40 character display and the 32 represents 32K RAM. The 4032's CPU was a MOS 6502 and had a speed of 1MHz. The Commodore PET 4032 was very successful in schools.
However there were some legal issues with Commodore's PET because there was already a
PET in Germany. Due to this Commodore's next computer was a CBM and not PET. CBM stands for
Commodore Business Machines.


I think that the Commodore PET 4032 and that the Apple Lisa were two of the most important computers in history even if one of them was not commercially successful.
In terms of popularity these two computers were very different. Over the course of
two years
only
100,000
Apple Lisa's were sold.
There was an extreme price difference of $8700 (£5323.05) between the $9995 (£6115.39) Apple Lisa and the $1295 (£792.49) Commodore Pet 4032.

Social, Ethical
and
Legal effects
Definitions
Social : wanting and enjoying being with others.
Legal : concerning the law or "permitted by law" (http://dictionary.reference.com/browse/legal?s=t).
Ethical : code of conduct and moral side of things.
Examples
Spending lots of time on websites such as Facebook.
Social :
Ends up spending less time with people they actually know and have met before. Many children nowadays spend lots of time on these websites instead of going outside or playing intelligent games such as puzzles.
Ethical : Information which was meant to be private ends up being public.
Doing work on a computer, such as essay writing at home.
Ethical : People could copy another persons work.
Legal : They could be copying copyrighted things which means that they are violating the law. The copyright means that the document officially cannot be copied without permission.
Being addicted to computer games.
Difference
Social : Sometimes when these people are in the real world and not playing computer games they are confused and still think that they are in the world of their last game. This has led to some of them to kill or harm others.
Ethical : They are not acting as one should to others and they should try to stop their addiction for the sake of others.
Legal : This could be counted as murder and it is violating the law.
