History of computers
-
The Diffrence Engine
The first ever caculator/computer build by Charles Babbage it could only add numbers by one therefore the formula is n+1 and it had to be used manually. -
The Analytical Engine
The Ideas was from the same person who build the difference machine, it was unsuccessful and was only build in the late 1940s -
The Caculating Clock
A machine able to add and subtract numbers at more then 6 digits at a time and is a much better machine than the difference engine that charles babbage made during the 1830s, -
Stepping Reckoner
This Machine was able to add and subtract numbers up to 12.
It was lost somewhere and was never found out until recently. -
Arithmometer
Not exactly a calculator but it could calculate equations that were harder and it was the size of a desktop. -
Z1/V1
It was a pretty much a calculator but it was the size of a table. -
The Typewriter
It can type things like a keyboard but by using ink and adding the bad things, if you make a mistake you can't erase it. -
The Commodor PET
This is the first PC (Personal computer) it could do all the things a normal computer could do but a lot more pixelated and slow. This computer pretty much projects very little amounts of light therefore the background of the desktop is black and the words are green. Games can be played but they have to be simple like "Space Invaders" one of the first PC games to be ever created. -
The IBM 5150
The same thing as the Commodor PET except there are now disk readers for the monitors. -
The SUN SPARC-STATION
This computer is very similar to a modern computer but once again has much fewer options and is obviously slower. -
DELL Optiplex
this was a computer that was recommended for gaming as the moniter was much more higher performance but compared to a normal PC today it is very slow. -
The Mac PC
this is one of the first mac PCs and is slightly beter then the DELL Optiplex. but has a apple system as most people those times were more use to windows. -
The Lenovo Home PC
This is a very recent home PC made for home uses and is very and fast and reliable. -
The iPhone 4s
this is basically a smaller version of a computer that is portable. it is one of the most advanced technology ever created.
