Central Processing Unit.
Development of the computer chip started in 1958 when Jack Kilby of Texas Instruments demonstrated that it was possible to integrate the various components of aCPU onto a single piece of silicon. These computer chips were called integrated circuits (ICs) because they combined multiple electronic circuits on the same chip.Subsequent design and manufacturing advances allowed transistor densities on integrated circuits to increase tremendously. The first ICs had only tens of transistorsper chip com...

Since the late 1980s
mid-1990s, strong criticism emerged and researchers debated the pros and cons of developing such “dangerous” technologies. However, technological limitations at the time still allowed researchers to claim these social concerns were theoretical rather than actual, and the matter faded from public consciousness again until the early 2000s. By the turn of the 21 st century, mobile phone penetration was globally on the rise, and a vision of ubiquitous information and communication technologies n...

Electronic Music
I
INTRODUCTION
Electronic Music, music that requires the use of electronic devices to produce or manipulate sound during its composition and performance.
III SYNTHESIZERS AND OTHER ELECTRONIC TECHNOLOGY Moog SynthesizerThe musical synthesizer was invented by American Robert Moog. Soon after Moog introduced an early version in 1964, itbecame known as the “Moog Synthesizer,” and then simply as the “Moog.” Here, Japanese composer Isao Tomita uses aMoog synthesizer in his studio.Huynh Cong/AP/Wide World Photos In the 1950s sound synthesizers were developed, principally in the United States. Synthesizers enabled composers to produce sounds electroni...
