Batteries are a form of contained electricity which allows you to provide an electrical charge to the components within your cell phone. Batteries are not permanent though and are susceptible to fatigue and loss of charge. New advancements in battery technology have been making leap forwards in providing longer lasting and smaller batteries. Fixed lines have just as many pros and cons as cellular phones. To receive or transmit data over the fixed line a modem is needed on each end of the line. The modem takes the digital information and turns it into tones that have been specifically selected for the transmission over telephone network. The modem at the other end is responsible for turning the tones back into digital data. Data rates were limited until digital subscriber line (DSL) was introduced. DSL used the...
