Which of the following is true of parallel transmission?
Options: It involves the simultaneous transmission of eight bits., The speed is quoted in bits per second., It is slower than serial transÂ¬mission., Most microcomputers commuÂ¬nicate with other computers in this mode.
A p- channel enhancement type MOSFET performs much the same function as a PNP transistor, except that
Options: it operates much faster, it is considerably larger, it is controlled by voltage rather than by current, so that it requires very little current at the control terminal, it is controlled by current rather than by voltage like a bipolar transistor.
Options: Acts as the fastest port to all servers., Provides multiple collision domains on one switch port., Breaks up broadcast domains in a layer 2 switch internetwork., Provides multiple broadcast domains within a single collision domain.
