computer
The history of the computer is very interesting because it shows how the man manages to produce the first tools to record daily events since the beginning of civilization, when nations began to form groups and trade was already a living. The historical evolution of data processing is divided into four phases: 1 .- Technical Records 2 .- computing devices 3 .- punch card programs 4 .- electronic computers a computer processes data. Companies develop data processing departments (computer programming), as the computer processed data to produce meaningful information. The data is built of facts and figures raw (unprocessed). The information consists of data processed, the information has meaning, not data. The computer and its applications perform the processing of the input, so the program converts the data into useful information.
Computer; definition: In the most basic level, a computer processes data. Companies develop data processing departments (computer programming), as the computer processed data to produce meaningful information. The data is built of facts and figures raw (unprocessed). The information consists of data processed, the information has meaning, not data. The computer and its applications perform the processing of the input, so the program converts the data into useful information. Data is typically inserted through an input device such as a keyboard. The information is often sent to an output device such as a screen, a printer or a disk file.The input and output of the computer may come and go many different device types.
Computer History: In 1670 the German philosopher and mathematician Gottfried Wilhelm Leibniz perfected this and invented a machine that could also multiply. The French inventor Joseph Marie Jacquard, when designing an automatic loom, used thin wood perforated plates to control the fabric used in complex designs. During the 1880 American statistician Herman Hollerith conceived the idea of using punched cards, similar to Jacquard's boards, to process data. Hollerith got compile statistical information for the population census of 1890 the United States using a system that pretended to punch cards over electrical contacts. Also in the nineteenth century British mathematician and inventor Charles Babbage worked out the principles of the modern digital computer. He invented a series of machines, as the Difference Engine, designed to solve complex mathematical problems.Many historians consider Babbage and his partner, British mathematician Augusta Ada Byron (1815-1852), daughter of English poet Lord Byron, as the true inventors of the modern digital computer. The technology of that time was not able to transfer their successful practice concepts, but one of his inventions, the Analytical Engine, as had many of the characteristics of a modern computer. It included a stream or input stream in packet form of punched cards, a memory to store data, a processor for math and a printer to make permanent registration. Analog computers began to be built in the early twentieth century. Early model calculations performed by rotating shafts and gears. These machines were evaluated numerical approximations of equations too difficult to be resolved by other methods.During the two world wars were used analog systems, first mechanical and then electrical to predict the path of the torpedoes on submarines and remote operation of the pumps in aviation.
History of Linux and UNIX: Linux was born as a result of Linus Torvalds, inspired by MINIX, the operating system developed by Andrew S. Tanenbaum in his book "Operating Systems: Design and Implementation". Book in which, after a comprehensive study on the services must provide an operating system and ways of providing these, enter your own implementation of the UNIX source code form in C and assembler, in addition to the instructions to install and improve it. The first version of Linux, listed as 0.01 contained only the rudiments of the kernel and run on a machine with the installed MINIX, that is, to compile and play with LINUX was necessary to install MINIX Tanembaum. On October 5, 1991, Linus announced the first version of 'official' version of 0.02 with this and could run the bash (GNU Bourne Shell) and gcc (GNU C compiler). After version 0.03, Linus changed this number by 0.10 and after input from an initial group of users increased again to 0.95 designation, reflecting clearly intends to announce soon a version of 'official' (under the name 1.0 ).
