The first computers of this generation were developed for the atomic energy industry. Instead of typing commands, the user can simply speak into a headset. The computer became smaller in size, faster, more reliable and less expensive. In 1943 an electronic computer name the Colossus was built for the military. Even these systems are quite limited -- you must speak slowly and distinctly.

Silicon is commonly doped, or mixed,with other elements, such as boron, phosphorous and arsenic, to alter its conductive properties. There are over 400 generations of individual progressments in major computer technology. The day the microprocessors invaded into our lives, they put a major impact on our day-to-day life. Today's latest microprocessor contains tens of millions of microscopic transistors. The early versions of these machines were developed for the atomic energy industry.

Fourth Generation Computers 1975-Present The fourth generation computers started with the invention of Microprocessor. According to functionality, Type of computers are classified as : Analog Computer An analog computer spelt analogue in British English is a form of computer that uses continuous physical phenomena such as electrical, mechanical, or hydraulic quantities to model the problem being solved. I circuit , which is used in a computer for any arithmetical or logical functions to be performed in any program. Wilkes at Cambridge University in 1949. Feynman's classic talk in 1959, the term nanotechnology was first coined by K. There are no other truly fundamental aspects of computer programming; everything else we talk about will simply be the details of a particular, usually artificia … l, mechanism for telling a computer what to do. This is a rather broad question.

A number of voice recognition systems are available on the market. Intel 4004 chip was the first microprocessor developed in 1971. It is a very useful tool that will continue to experience new development as time passes. Other than that, have fun, enjoy, and share the knowledge. These were inefficient materials which generated a lot of heat, sucked huge electricity and subsequently generated a lot of heat which caused ongoing breakdowns.

Second Generation Computer were built usi … ng transistors that were much smaller and required less power and space. They used magnetic tapes and magnetic disks for secondary storage. This invention was the transistor whichfunctions like a vacuum tube in that it can be used to relay andswitch electronic signals. The First Generation: 1944-1958 The Vacuum Tube Years The first generation computers were huge, slow, expensive, andoften undependable. Transistors allowed computers to become smaller, faster, cheaper, energy efficient and reliable. The instructions are executed one by one in sequence and finally produce the desired result.

It is widely believed that lithography is quickly approaching its physical limits. These scientists include John Barden, William Brattain and William Shockley. The work of processing may be the calculation, comparisons or the decision taken by the computer. The proper and accounts diagnosis is done with the help of computer. About Dinesh Thakur Dinesh Thakur holds an B. Scientists are constantly working to increase the processing power of computers.

It was designed principally by and , the inventors of the. You have the greatest Customer care. Though computers do not have a very long history behind them, but they have very rapid evolutionary changing phases within a very short span. The machine was 25 feet by 50 feet in length, contained 5,600 tubes, 18,000 crystal diodes, and 300 relays. They stored in the form of propagating sound waves.

The five generations of computers

Computers at this time were usually kept in special locations like government and university research labs or military compounds. Computers consist of many chips placed on electronic boards called printed circuit boards. Manufacturing cost was also very low. Second-generation computers still relied on punched cards for input and printouts for output. Mostelectronic devices today use some form of integrated circuitsplaced on printed circuit boards -- thin pieces of paper or fiberglass bonded with phenolic or epoxy resins that have copper electrical connectionsetched onto them. The mercury delay line memory tank temperature was very closely controlled as the speed of sound in mercury varies with temperature. The output was displayed as printouts.

I can't write your speech for you -- that would be cheating and if you copied it, it would be plagiarism. The mini computers were introduced in this generation. It was first developed by T. Invented in 1947 at Bell Labs, transistors have become the key ingredient of all digital circuits, including computers. It's safe to say that without the invention of transistors, computing as we know it today would not be possible.

However, they generally require an extended training session during which the computer system becomes accustomed to a particular voice and accent. Dinesh authors the hugely popular blog. The increased power of these small computers meant they could be linked, creating networks. The honaur of developing microprocessor goes to Ted Hoff of U. These were a frequent source of failures. There were four competing technologies for providing computer memory: electrostatic storage tubes, acoustic delay lines mercury or nickel , magnetic drums and disks? There are also voice recognition systems that can convert spoken sounds into written words, but they do not understand what they are writing; they simply take dictation. There are different types of chips.
