Which generation of computers uses a vacuum tube?

What are computer tubes used for?

Computer tubes, also known as vacuum tube computers are programmable computers that uses vacuum tube logic circuitry. They were used to solve computational problems much like modern day computers.

What are the uses of vacuum tubes in today's computers?

Since the second generation transistorized computers there has been no use of vacuum tubes in computers except for one thing, CRT displays. In the last few years even that has been eliminated by modern flat panel LCD & LED displays, which are much lighter and less power hungry than CRT displays were.

Anyone know where you can find vacuum tube diagrams for a 2003 Dodge Dakota Pickup truck?

No vacuum tubes on the Dakota. It uses electric servos.

How many vacuum tube in one transistor?

There are no vacuum tubes in a transistor. A vacuum tube is an electronic device that uses a heated cathode in a vacuum to direct and control an electron stream to an anode, also known as the plate. The vacuum tube is old technology, but it is still used today, typically in high power applications such as transmitters. A transistor is an electronic device that uses solid-state semiconductors to similarly control an electron stream. The transistor is newer than the vacuum tube. It offers lower power, smaller size, easier use and other enhancements over vacuum tubes, within limits, of course, such as voltage and power.

What are the advantages and disadvantages of the third generation?

The advantages of the third generation computers are:1. faster2. smaller3. uses less energy4. uses high level programming5. cheaper7. lower maintenance costthe disadvantages are:1. still require air conditioning

What are characteristics of each computer generation?

Each computer generation had different characteristics. The first generation used vacuum tubes, the second used transistors, the third used integrated circuits, and the fourth uses microprocessors. The fifth generation is still developing and will use Artificial Intelligence.

What is involved in microdermabrasion?

the physician uses a handheld instrument that buffs the skin with aluminum oxide crystals; skin flakes are removed through a vacuum tube.

What are the difference between computers 1 generation to 5 generation?

This is a rather broad question... There are numerous differences between various generations of computers, and numerous things that could be meant by the term "computers." I have to assume the question refers more specifically to the various generations of computer processors. Between the first Pentium and the latest Core 2 Duo processors, for example, quite a few changes have taken place. * Clock speed - newer processors generally run at higher speeds; this is a measure of how quickly the processor can operate, expressed in hertz. This is not the only relevant figure when comparing different processors. * Number of cores - in the last couple of years, chip makers have touted the number of cores on their processors; think of each one as a separate mini-computer of sorts, able to complete its own tasks; a limitation with multi-core processors is the software, which often cannot take full advantage of multiple cores. For further information, please clarify the question, and perhaps the intended purpose (is this information intended to help with an upcoming purchase or simply personal edification?).

When was the last computer that uses vacuum tube turned on?

At least one hobbiest designed and built vacuum tube computer was built after 2000. It is probably still runningtoday.The ABC recreation vacuum tube computer at Ames, Iowa still runs today as a museum exhibit.Four panels of the original ENIAC are still running today as a museum exhibit.The last UNIVAC I was shutdown in 1971 by a Tennessee insurance company that had used it for over 13 years.The last SAGE air defense AN/FSQ-7 vacuum tube computer was shutdown in 1986.

What generation of computer require air conditioner?

All really large computers regardless of generation need an active cooling system (e.g. air conditioner, circulating liquid Freon, circulating chilled water) to dispose of their waste heat.I even have a quad-core microprocessor desktop computer that uses an internal sealed liquid coolant system to transport the waste heat from the microprocessor to the blower. The air leaving this computer's vents can be hot enough when it is working hard that it would really help if the room had an air conditioner!first generation (vacuum tube) computers all needed internal active cooling systems, because vacuum tubes produce very large amounts of waste heat even when idle!second generation (transistor) computers may or may not have needed internal active cooling systems, but the computer room they were installed in was usually air conditioned to the point of being uncomfortable to be in (except for the smallest machines in this generation, some of which could be installed in ordinary office rooms).third generation (integrated circuit) computers only large machines (e.g. supercomputers) needed significant internal active cooling systems (which were usually either circulating liquid Freon or circulating chilled water), although usually no longer necessary for most computers of this generation the computer room they were installed in was usually air conditioned to the point of being uncomfortable to be in.fourth generation (microprocessor) computers have usually not needed internal active cooling systems, with the exception of very high performance multicore microprocessor systems and microprocessor based supercomputers.

What sealed vacuum chamber on a television set where images are displayed?

A cathode ray tube (CRT) television set uses a sealed vacuum chamber to display images. The chamber is filled with phosphor-coated glass screen where electrons generated by the cathode ray tube strike to create the images we see on the screen.

Features of 1st to 5th computer generation?
