The data flow on the system board

The data flow on the system board
On the system board, you will find the CPU, which is the "brain" of the PC and the busses. The
busses are the nerve system of of system board. They connect the CPU to all the other
components. There are at least three busses, which you can see below. You can read more
about those on the following pages.
The busses are the PC's expressways. They are "wires" on the circuit board, which
transmit data between different components. One "wire" can move one bit at a time.

In the following text, we start from a modern Pentium board. We will look at busses, chip sets
and CPU's. Here is an illustration of the system board "logic," which you can print out.

Here, you can switch to read about what data really are. Or click to move to the page about the
CPU. Or read more about data, and how they are saved in the PC file systems.
