History of Computer II
#1


In last thread we discussed about First mechanical computer which introduced the Automatic Computing engine Concept.
Now in this thread we will discuss about the First Programmable Computer which is the next evolution of Automatic computing concept.

First Programmable Computer:
The first computer which is programmed was developed by a German named Konrad Zuse. Now am gonna tell about him first.

KONRAD ZUSE:
  • Born June 22,1910,Berlin and Death December 18,1995 at an age of 85!!!!
  • Built the first programmable computer machine and he developed the Z1,Z3 and Z4 Computer will explain about it later.
  • Wrote the first algorithmic programming language called Plankalkul in 1946 and he is one of the first people to create a commercial computer and computer company.

Now lets back to computers he developed Z1,Z3,Z4 Modern Computers.
Now we can see about whats that Z1?
Z1 began development in 1936 by our hero Zuse in his parents living room.
Z1 had 64 word memory where each word contained 22bits and clock speed of 1Hz and to program the user insert the Punch tape into a punch tape reader and output is also available in punch tape format.

Z1 components:

and days rolled, developments changed in Z1 circuits and simulations and developed Z2,Z3,Z4.
I wonder that most of the scientist was caught by fund! Yes, Zuse was also fall in that. To develop Z2 Machine Dr.KurtPannke who manufactured calculating machines helped Zuse and completed in 1939.
In 1940 Zuse founded Zuse Apparatebau his own company to built computers.
Z3:
Zuse developed Z3 in 1941 which was a Secret project of German Government and it was an electromechanical computer.
In 12 May 1941 the Z3 was presented to audience of scientists in Berlin.

Z4:
Z4 was the first commercial digital computer and it is very similar to Z3 but it is enchanced in Memory of 32bit and a special unit Planfertigunsteil which punched program made programming.
Build in his own company between 1942 to 1945.

the quote by Zuse is

"At least Zurich has an interesting nightlife with the rattling of the Z4, even if it is onlu modest"
