High end keyboards help N key rollover and may accept an arbitrary number of keys on the identical time. Modems can be attached via USB, a conventional serial port, or an inner card slot. Internal modems and USB modems are extra easily auto-detected by the operating system and fewer prone to have problems with setup. USB and serial port modems often require an extra energy supply block. Mobile broadband modems are sometimes used to attach computers wireless to mobile networks.
