How did computers evolve ?

Answer 1

Through the adaptation of the human brain to more technical matters.

The more the brain evolved the more it could invent/improve on things

Answer 2

We started out using a flip-flop (called a mono-stable multivibrater by Brits back then) to indicate if something was on or off. We used vacuum tubes to build banks of these to store information but they created lots of heat, used too much power & were very big for the small amount of info they stored. Then we discovered a means of storing the information on a magnitized iron core by sending a pulse to magnitize the core or de-mmagnitize said core (this was called core memory). Core memory was a big step up from the flip-flop, but 4K bytes filled a box about the size of today's PC. Chuckle, 512MB would fill an entire floor of a standard office building.
During the 50s the transistor arrived, making the flip-flop smaller & much easier to use, and reducing power use.
Card readers & paper tape readers/punches became the "fast" methods of entering programs & assy language programming replaced machine language programing (where we entered the program 1's & 0's from the front panel switches). Later higher level program languages like Fortran & Cobol made programming much faster & easier.
In the mid 60s Texas Instruments produced the 1st "micro-chips" & although they were slow, expensive & typically contained fewer than 30 devices, they drastically reduced the size of the average computer.
I'll cut this short & move to apple & IBMs introduction of the 1st home user class of computers in the early 80s. If you have further questions address them & I will give you specifics... as I designed many computers & peripheals in the era you are refering to.

Answer 3

"Who invented the computer?" is not a question with a simple answer. The real answer is that many inventors contributed to the history of computers and that a computer is a complex piece of machinery made up of many parts, each of which can be considered a separate invention.

This series covers many of the major milestones in computer history (but not all of them) with a concentration on the history of personal home computers.

Answer 4

Blaise Pascal was the first to make a working calculator, it may not be a computer, but still good enough...
Also, you may like to research about Automaton, made in the 17th century and onward, those were very interesting.

Actually the first discovery that enable the democratization of computers was the transistor. Discovered at the end of the 60`s. It enable the replacements of bulbs, that were burning often...

Answer 5

Back about 1970 a NASA Physicist showed me a computer in a large building that went all the way around the room. I'm not sure of the rooms size anymore. (About thirty by forty feet) and it had all of those spinning items you can see in some old movies or reports. And in the middle of the room was a new computer that was three feet X three feet X four feet. And he was so proud of it because the new smaller one could do all that the great big one could.
Today we could probably put all that the new one could do in the palm of our hands.

Answer 6

If I could draw a picture of it, it would be the opposite of the Evolution of man, where the computer starts huge and beefy but evolves to a tiny handheld device.

Answer 7

took the evolution of humans for computers to evolve ;p

Answer 8

by hundreds of Japanese scientists
working round the clock
to improve on the latest tech knowledge
and then the Japanese electrical engineering company's
are given the blueprints
for a improved comp system
by making a smaller faster and better computer
than the last edition,it originated from mathematicians

Answer 9

natural selection. the weaker forms (tandy TRS-60, commodore series and RF-2) died out and only 2 were left the IBM and the Apple.

Answer 10

in a way un answerable by yahoo answers, but we can point you in the correct direction, start of with a search of computers on wikipedia
