Calculation of development : first, when most people are way process of calculation is about: finger count count --- --- stone rope knot count ---- pi - Abacus -....--- Pascal computer (Modern )
Eight on the Eight Diagrams bar chart , if the binary related, as it related to mathematics bar chart consists of three lines, each line may be one or two which is an array of 2 * 2 * 2 is the thought of mathematics. Gossip can be seen from 0 to 7, a binary word, which is a three-digit binary number, and extended to 64 Book 6 is a diagram.
Loom is a long history of semi-mechanized cloth weaving tools. Early Neolithic people in addition to hand-woven, woven fabric has been invented original machine.
a vintage jacquard: vintage jacquard is one of the important inventions of ancient China, it is in use as early as the Shang period.
. B Jacquard Jacquard: Early 19th century French Lyon is world famous silk capital. Lyon silk workers weave silk brocade pattern gorgeous, exquisite, had been regarded as treasures, but they are using tools but still old-fashioned hand-jacquard. Such machines needed someone to stand above the warp effortlessly lifted one by one, put down, as if the actors manipulate marionette same. One can imagine the intensity of work in this way is very large, the efficiency is very low.
c computer originator: In 1836, two years after the death of Jacquard, computer science pioneer, the famous British mathematician Charles Babbage (Charles Babbage, AD 1792-1871 years) created a computer-iron wheel with wooden teeth, with to calculate the many mathematical problems. In this iron wheel with wooden teeth computer, using the Babbage principle of the Jacquard punched tape computer programming.
d computer development: Following Babbage, 1889 American statistician Herman Hollerith (Herman Hollerith, AD 1860-1929 years) in accordance with the principle of Jacquard Jacquard loom, the use of punch cards, development the punched card tabulation system for population census, the census substantial increase in work efficiency. Hollerith punch card tabulating system, in fact, a mechanical computer systems, is considered the prototype of the modern computer.
With the development of history
The parent computer - Babbage Difference Engine invention: complex into simpler arithmetic operation
The world's first general-purpose computer mathematics - analysis machine (whose drawings by the founder of Babbage and Ada programmers create technology together to achieve but because the machine ahead of a century and therefore could not create)
IBM predecessor was founded in 1896 by Dr. Huolie Si drawings by the Analytical Engine Support
1906 Father Lee Devils Lester tube of foundation (triode vacuum tube called a computer development )
In 1924 IBM formally established
(Mark One last a prehistoric computer (mechanical / electrical))
The first computer 1937 Atanasoff - Berry Computer (Atanasoff-Berry Computer, a computer typically abbreviated ABC) only for solving linear equations
In 1946, ENIAC, called the Electronic Numerical Integrator And Computer, namely Electronic Numerical Integrator and Computer. ENIAC was the world's first general-purpose computer, also following a second computer after the ABC. Then von Neumann (the father of the computer) to improve the ENIAC, in the "Computer Industry" which can be seen more computer history, but some of the content inside is not cleared as expressed on first general-purpose computer and now says some contradictions .
I like more than just a rough summary of contents
Here are my general knowledge about computer knowledge
CRP is the first computer monitor (is the big ass) - (with the development) - liquid crystal displays
About the relationship between applications and os and applications
Probably constructed chassis
Operating system development: 1, batch processing system
2, online batch processing, offline batch processing system (CPU requires busy, etc.)
3, time-sharing processing system (a one execution - after serial, using the time-sharing, to the user as if the task is complicated by the disadvantages are: the time each task will take longer, and can not be real-time processing. not suitable for real-time tasks requiring high)
4, a general purpose processing system
