To design your own page Web can be huge, but sometimes you do not have the time necessary to realise this project. In a case as this generally ideal is to use some to freelancer, or some company. Many companies exist that can do this work by you, but you need to have a general concept of the content that you want to include in the site. You can include a description of how you want that it is the site. The creation of specialized Web sites has many advantages on securing to a group Web in which you are going to create your Web site. For example, the content in a page Web only adapts to the needs while a smooth group is obtained and still it requires of one to most of do the work of development. Often, the company that also creates the page Web maintains it by you. In order to initiate this process, one is due to discuss with the equipment of development with respect to the options and the sensation of the site.
You can also have surveys. A proposal that can show the concept before it is approved. Once approved, to initiate the work one would begin in the site and it can at any time ask for the updates on the progress during the creation process. To contract a company so that it constructs to your Web site is often the direction devises to follow. Nevertheless, all the developers are not equal to make the investigation to mainly find one that adapts to your needs and something that adjusts to your budget.
In this generation the auxiliary memories were extended and they were created magnetic disks of great capacity. The printers were designed and optical readers and were developed the programming languages, appear the new programming languages denominated High-level languages. Third generation 1965-1975 is characterized by the appearance of the integrated circuits realised with silicon, the increase of the speed, the greater number of programs and languages: Cobol, Fortran and the appearance of the terminals to transmit data to the central processor at a distance, or vice versa. They appear the operating systems for the control of the computer, central depots of data to which it is possible to be acceded simultaneously from several users. The first apparatus based totally on integrated circuits is IBM series 360 that incorporated in addition an Operating system for the control to the machine.
In the middle of the 70 they appear the first minicomputers. Fourth generation the 1975-1990 most important characteristic of this generation is the appearance of the microprocessors Chip, that are circuits with great amount of transistors integrated in a small space. Other characteristics are the increase of the entrance capacity and exit of data, major duration of the components, new programming languages Logo, Pascal, BASIC, data bases. Intelligent terminals with own memory arise and the word processors. It is reduced of the size and cost of the computers and improves the speed of calculation. A new era with the appearance of the Personal computers or Personal Computer is abre.
The first microcomputers had a price both superior to million pesetas. At the end of the 80, the price was on the two hundred thousand pesetas and its yield was 100 times greater. At this time it emphasizes the development of the operating systems, that look for an integration between the user and the computer, through the use of graphs. Fifth generation 1990-hoy the revolution arrives with the microprocessors of new generation. The speed goes off and the successive generations of microprocessors follow one another, becomes general the personal computer. The alliances between rival companies are tonic of this time, IBM signs agreements with Apple and Motorola, for the production of a new series of denominated microprocessors PowerPC. Intel sends the Pentium microprocessor like answer to this alliance. In agreement they advance the years the speed and the yield of the microprocessors is greater thanks to the advances in microelectronics. It is necessary to emphasize that on the other hand other companies continue working in supercomputers that incorporate several microprocessors in the same machine. According to Law of Moore the number of transistors by microprocessor duplicate every 18 months. One has turned 30 years in the last and it is anticipated is fulfilled during next the 20 years.
The present investigation on the Antecedents and Generations of the Computers, is directed to offer information updated on this important field of the Human activity, and to provide explanation about why and since it has been the advance of the computers until our times. The modern times the Computers have become a tool of extreme importance, not only for the development of our towns, but also, for the development of Science, new Technologies, due to the increasing advances that in the matter have been reached. Due to the increasing necessity of our present world, to obtain a greater knowledge and understanding of the technological advances in the industry of computer science, it is that I have decided to approach the subject of the simplest way, so that it is included/understood by which they are excited by this race. For the accomplishment of this work, besides systematically analyzing the different written sources of intelligence on the subject, also I obtained data (interviews) of some friendly that have attended the race previously. Finally, I want to mean that a work of the magnitude as " is them the subject; " Antecedents and Generations of the Computadoras" " hardly it can be boarded exhaustive, nevertheless I create to touch the aspects flagranter than they serve as aid to future investigations I HISTORY OF THE COMPUTATION UNTIL CENTURY XVIII THE FIRST STEPS 1.1 The ABACUS OR the TABLE OF CALCULATION Before having words or symbols to represent the numbers, the primitive man used its fingers to count.
The old abacus consisted of introduced stones in furrows that were realised in the sand. These movable stones took to the development of the abacus, which already knew in the year 500 A.C and was used by the Egyptians. " " The word calculation means stone; in this way calcular" arose the word; ".
Battery If you travel much or regularly you use your computer of movable way, the importance of the life of the battery is critical. The majority of laptops of medium size now has a life of the battery among 4 and 5 hours, so you are not satisfied to less. Once again, which beams with your laptop determines what so fast you will exhaust the battery. If you like to see films, decides by an option that lasts more. The secondary batteries or the packages of batteries are not cheap, but the investment definitively can merit the pain. Use of networks Almost all the laptops now include to a connection of Ethernet for the access at a high speed of Internet and cards of radio networks including, to be able to have wireless access in points as much public like in your homemade network. Perhaps you want to consider to include the Bluetooth capacity, that allow you to connect to your laptop with other apparatuses qualified by Bluetooth, such as printing, horns, etc.
Other Connections Some other connections what to look for includes a port VGA for an external monitor, cables of headsets and microphones and at least two ports USB to connect other apparatuses, such as digital cameras, reproductive MP3, flash memory, etc. Perhaps for use in the home, also you want audio-visual connections (A/V) to connect directly to your laptop with your television. In spite of the complexity of all the options available, the good news is that laptops of nowadays is fast, powerful and accessible. Armed with a little knowledge, there is no reason by which you cannot find laptop that she is perfect for you!
