Man tries to create a tool to help calculate since ancient times, and have tried to develop the tools to be easy to use increased, respectively. In 5000 years ago. Humans began to recognize the use of fingers and toes to aid in the calculation and development as other devices.The evolution of the computer. Starting from the evolution of the calculation. Equipment used in any calculation or a calculator because it can be considered a "computer" was a calculated one exerted by may begin from the count with stones, wood chips, twigs, the tick as a symbol by a wall 3. This calculator is a template of the current computer: lukkhit (Abacus) 7. Ron a tea beige (Charles Babbage: 1792-1871), British scientists have fabricated machine difference (Difference Engine) in 1832 as a calculation that contains a large number of gear teeth. Be able to calculate the value of a table automatically, and then send the results to the pegs on the sheet for printing. The difference machine has developed a beige again in 1852 by obtaining subsidies from the British Parliament, but they must be stopped when the actions were not as hoped.After that, the beige, turned to machine design analysis (Babbage's Analytical Engine) by the "memory" which is the unit for counting "gear teeth" that can add, divide, multiply, divide. "operating" card punch card is similar to calculating what the "Variant" card. Select whether to use the information from memory, and "best visual effects", "or" card puncher, but the person who introduced the concept of a beige building tools and analysis (Analytical Engine) was the son of the famous Henry (Henry) beige in the year 1910.The idea of the beige and the difference analysis about the computer industry in a much later age. Receive a "a father operates a computer" somya because it contains an important part 4.1. private storage is used to store data and calculated results.2. as used in the mathematical processing.3. the console is used to move data between the storage and the processing section.4. get the data and displays the result in the receipt of external air into the storage section and the calculated results make this analysis. It looks similar to the components of the current computer system.There are 4 computer era.The era of one computer.Starting from the year 1951-1958 using vacuum tubes (Vacuum Tube) is an important working cycle is initiated at the age of knowledge about computer technology, reliance construction occurs. The UNIVAC computers, ENIACUNIVAC computer, for use in the business world's first machine.Light chali and คเกิรต on behalf of company a. Remington Rand (Remington Rand) has created a machine to another computer at a later time was UNIVAC (Universal Automatic Computer), the demographic of the United States to be working in the decimal number system, the same. However, it is still a very large UNIVAC length 14 ft wide, 7 feet, 9 feet, half have 5000 vacuum tube tube, but with high working speed. Numbers or letters can be stored in memory up to 12000 a.ENIAC, the first computer in the world.John Leu level. Maurice (John W. Mauchly) and chali je WordPress per El คเกิรต (J. Prespern Eckert), the received order from the United States Army. In the 1946 ENIAC created a calculator when it is considered to be "the world's first electronic calculator or the world's first computer" is the abbreviation of the ENIAC Numerical Integrator and Computer Electronics as the calculator is intended for use in the armed forces, using artillery firing table calculations. Artillery shells relies on vacuum tube number tube weighs 30 tons used 18000 room area 15000 square feet of working time must take up to 140 kW in the decimal number system, this light chali ENIAC machine is a concept derived from the ABC of Ta na car software.The identity of the computer era at 1.Use vacuum tubes as the main component.The machine is large. Using a high power High heatWorking with the language (Machine Language).With the development of Symbolic Language and sign language, such as Assembly.The second generation computers.ปี ค.ศ. 1959 - 1964 ใช้ทรานซิสเตอร์ (Transistor) เป็นวงจรสำคัญ ซึ่งเป็นอุปกรณ์ที่พัฒนาโดยนักวิทยาศาสตร์ชั้นนำสามคนจากห้องปฏิบัติการเบลล์ (Bell Lab.) ได้แก่ วิลเลียม ชอคลีย์ (W. Shock), จอห์น บาร์ดีน (J. Bardeen), วอลเตอร์ แบรทเตน (H. W. Brattain) โดยทรานซิสเตอร์เป็นแผงวงจรอิเล็กทรอนิกส์ที่มีขนาดเล็กกว่าหลอดสูญญากาศมาก แต่มีความจำที่สูงกว่า ไม่ต้องเวลาในการวอร์มอัพ ใช้พลังงานต่ำ ทำงานด้วยความเร็วที่สูงกว่า นอกจากเทคโนโลยีเรื่องวงจร ยังมีเทคโนโลยีอื่นมาร่วมด้วย เช่น เกิดภาษาคอมพิวเตอร์ขึ้นมา คือ ภาษาแอสเซมบลี (Assembly Language) และภาษาระดับสูงต่างๆ เช่น ภาษา FORTRAN, COBOL สำหรับหน่วยบันทึกข้อมูลก็มีการนำเทปแม่เหล็กมาใช้งานFORTRANA computer that has a less-than-performance mainframe machine is working more slowly than the surrounding equipment and controls. However, the highlight of the mini is more than affordable mainframe systems. Applications do not need to use people too much. In addition, there are also those who know how to use more of this kind of machine is used by as many higher education place.A variety of mini-computers suitable for the job are available, both in engineering and science, industrial machine that is used by government agencies, most often the Department as this category.COBOL (COBOL).COBOL (Common Business Oriented Language: COBOL) is a language for use in the business world's first language. Developed in 1962 by the Board of Directors of the hotel SI (The Conference on Data Systems Languages-CODASYL) has a good point is that the data file can be used. Define the data structure. There is a document describing the programming style, the program provides information to developers, the next generation has a simple and easy.Third-generation computers.In 1965, the age of the computer-1670 as modified because the Panel is developing integrated circuit (IC: Integrated Circuit) company of Texas is the string hole tournament (Texas Instruments Co.,) making equipment available.
