And finally, the exhaust stroke. This is when the piston moves up and pushes the burnt gas through a one-way valve, which then goes back into the cylinder head and then through the exhaust manifold and exhaust tubes and the leads out of the car.

message over the Internet, it is broken into tiny pieces, called 'packets'.
These packets travel over many different routes between the computer that it is
being sent from to the computer to which it is being sent to. Phone lines,
either fibre-optics or copper wires ones, carry most of the data packets.
Internet computers along the path switch each packet that will take it to its
destination, but no two packets need to follow the same path. The Internet is
designed so that packets always take the best available route at the time they
are travelling. 'Routers' which are boxes of circuit boards and microchips,
which .....

established in 1977, led to wide-scale use of the technology. In 1987, just

providers rushed to install light wave systems. The US Sprint network was
the first to use a total fiber optic network to traverse the nation. By
1990, AT&T had installed 300 million miles of interexchange light wave
networks.
The advantages of light wave systems are many and include
• freedom from electrical disturbance
• tremendous bandwidth or information-carrying capacity
• small physical size
• relative low cost
The speed at which information can be moved through the fiber optic .....

The Internet: It Was To Be The Great Equalizer
<view this essay>.... get a seat at the commercial Internet table
a year ago, Baxter Phillip sees the Internet-induced level playing field as

While Web site affordability has made it easier for companies like
Phillip's to .....
