    the microprocessor: the vacuum tube, the transistor, and the integrated circuit. The Vacuum Tube American physicist Lee De Forest invented the vacuum tube in 1906. However, one must look back to 1879 when Thomas Edison first revealed the incandescent electric light bulb to understand how De Forest developed his idea. Edison’s invention consisted of a conducting filament mounted in a glass bulb. Electricity passing through the filament caused it to heat up and created a vacuum that prevented the filament

    miniaturization and optimization of electronics. To understand the monumental influence integrated circuits have in technology, one must understand what kind of technology society had before. Many computers in the 1950’s used something called vacuum tubes. These tubes were used in controlling electrical signals but were big (about the size of a cell phone), sometimes unreliable, and used a fair amount of power. Next came transistors (about the size of a coin), which greatly reduced the size of electronics

    containing three active electrodes of which vacuum tubes are a variety, by De Forest (Leach, 1995). This invention became the primary focus of the amplification industry, resulting in the discovery of stable operating vacuum tubes by Langmuir of General Electric in 1913. Consequently, the Japanese established a vacuum tube laboratory in 1914 and created a prototype high-quality vacuum tube in 1916. With the beginning of radio broadcasts in Japan, in 1925, vacuum tube technology quickly spread to England

    more powerful and more efficient and reliable devices .The history of computer development is always referred to in reference to the different generations of computing devices. The first generation (1940-1956) is the Vacuum Tubes. The first generation computers used vacuum tubes for circuitry and magnetic drums for their memory, and because of that they big and were often large, taking up entire rooms to build. They are so expensive to operate because they are very large and took a lot of maintenance

    or development of computer nowadays. The first generation of computer starting from years 1940-1950, this can be called as the first electronic computer. During this time, the computers were using vacuum tubes and it is more complex and huge. The vacuum tube is designed by Lee De Forest. The vacuum tube is a device that is used to amplify the signal by controlling the movement of electrons in an evacuated space. The first general purpose electronic computer was known as ENIAC or Electronic Numerical

    semiconductor that can act as a faucet for electrical current. The transistor can act as a switch maximizing the amount of current flowing through or minimizing it. This device has been essential in the advancement of modern technology; by replacing vacuum tubes and electromechanical switches that were unreliable, bulky, would overheat, and used too much energy. A basic electronic device can contain thousands to millions of transistors due to their small build. Transistors also lowered the cost of electronics

    or what kind of strings are used. The guitar amp is an instrument in itself just as a guitar, not all amps are created equally. An amplifier allows the guitarist to express his playing to the world. Some amplifiers are made using really simple vacuum tube circuits, and others are made from really complex solid state circuitry. Not any two similar guitars will sound alike, just as how any two similar people are not exactly identical. Amps are very similar in context; no two similar amps will sound
