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, whats 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.

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.

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.
