Figure 4 A Mainframe Computer System
A diagram showing more detail of a typical personal computer’s components is shown in Figure below
Although early PCs used separate integrated circuits for each of the various functions, today most of the
functions shown in the diagram are combined into just a few very-large-scale integrated circuits (VLSIs)
(usually just called chips or support chips). The block diagram in Figure below connects together many
of the important concepts familiar to you from previous chapters. The PC is driven by one or more CPUs,
which interface to memory and to the various I/O peripherals and ports by one or more buses.
