Inside a typical home, water is carried in pipes that are from one-half to three-quarters of an inch
in diameter. The pipes are part of the house, and if one springs a leak, the owner of the house is responsible
for fixing the problem. The pipes buried under the street that supply the water to your house, however, are
owned by the town in which you live and if they spring a leak, the town is responsible for making the repair.

Furthermore these pipes are typically much larger (some may be more than a foot in diameter), and because
they connect many homes, have the capacity to deliver more water than the pipes in your home.
Computer networks that most people use on a daily basis appear to span the globe. In reality, most computer
networks consist of smaller networks, which are in turn connected together to form larger networks. An internetwork,
or Internet, is formed when two networks are connected together. In an internet the networks are not connected
directly, but instead are connected using a computer that is connected to each of the individual networks. This
common machine is referred to as a gateway or router, and passes information between the two networks.
In this chapter we will take a look at computer networks.
