equipment". The first sound card was of 8 bit 11 kHz audio quality‚ similar to an AM radio. There are two parts to the "complicated piece of electronics"‚ the sound card. ADC and DAC were they. ADC is the analog-to-digital converter and DAC being the opposite (digital-to-analog converter). ADC took an analog signal from a device and converts it to digital signals for the computer to use‚ as DAC did the exact opposite‚ taking a digital signal and converting it to analog. However‚ in the future‚ there

Environmental effects of copper Copper can be released into the environment by both natural sources and human actions. Examples of natural sources are wind-blown dust‚ decaying vegetation‚ forest fires and sea spray. Other examples are mining‚ metal production‚ wood production and phosphate fertilizer production. Because copper is released both naturally and through human activity it is very widespread in the environment. Copper is often found near mines‚ industrial settings‚ landfills and waste

Second Industrial Revolution is considered to have begun in the 1860’s. New technologies and innovations such as the Bessemer steel converter‚ the internal combustion engine‚ the production and refining of oil and gasoline‚ the telegraph‚ the radio‚ electricity and the American system of manufacturing were created in the mid to late 19th century. The Bessemer converter worked by blowing air through holes at the bottom of the convertor to create a reaction that oxidizes the silicon and excess carbon
