How Gaming Servers Work
• When a person is
playing a game from
his or her computer
on the net, it connects
to game servers such
as these 

How Gaming Servers Work
• The following is a basic idea of how information
is sent from your computer to the server as well
as other computers on the network:
• When a person is playing a game online, what’s
a little more important is not the speed but
rather the amount of hops, traceroutes, that the
data packets from the computer have to bounce
through (routers/switches) to get to its
destination.
How Gaming Servers Work
• The moment When you input information from your computer it bounces.
• Here is a technical example:

How Gaming Servers Work
• The route that the data packet takes would be
from a house in Southern Idaho to several
places across the country until it reaches the
game server in Pasadena.

How Gaming Servers Work
You tell the computer to shoot
(Normally by pressing the left button
on the mouse)
The data packet is then sent to
the server, via traceroutes. The
server then receives the
information and sends another
data packet known as a reply
packet which confirms the
packet has been received.
How Gaming Servers Work
While at the same time, the server
calculates your position in 3D
space, the direction of the
projectile, and takes the position of
the enemy in 3D space and his
movement speed and direction. It
will then calculate whether or not
you successfully hit your target.
The server decides that you successfully hit your target.
It then sends data packets (hit points lost, armor, etc.) to
both you and the enemy telling you that the enemy has
been hit.
YOU ARE HERE

How Gaming Servers Work
• This is the basic idea of how information is
sent between gamers and the server.
• KEY TERM: Replication – Taking data
from a given client and replicating it
(duplicating + adding to it) back to all the
clients.
