Answer . \nHere you are discussing two different things. One is bandwidth, the ability to transmit a number of different signals down a wire at the same time, by 'multipl…exing' the signals, which is a term for separating the frequency spectrum that the coaxial cable will carry into multiple bands, and sending different signals on each band. \n. \nThe other involves the operating system a computer's Central Processing Unit is using. This must be loaded into the Random Access Memory of the computer during the boot process. To switch operating systems means re-booting the computer, to load the new operating system. However, computers can interface with users using a variety of different programs in a time-sharing computer system, because the programs are kept in Random Access Memory until the user logs off. This type of arrangement is rather rare, these days, as computers have become commonly available. (MORE)
