MQ-1 Predator

The MQ-1 Predator is an unmanned aerial vehicle (UAV) which the U.S. Air Force describes as a MALE (medium-altitude, long-endurance) UAV system. It can serve in a reconnaissance role, and it can also carry and use two AGM-114 Hellfire missiles. The aircraft has been in use since 1995, and been in combat over Afghanistan, Bosnia, Serbia, Iraq, and Yemen.

The MQ-1 Predator is a system, not just an aircraft. The fully operational system consists of four air vehicles (with sensors), a ground control station (GCS), a Predator primary satellite link communication suite and 55 people. In the over-all U.S. Air Force integrated UAV system, the Predator is considered a "Tier II" vehicle.

Ring network

A ring network is a network topology in which each node connects to exactly two other nodes, forming a circular pathway for signals: a ring. Data travels from node to node, with each node handling every packet.

Because a ring topology provides only one pathway between any two nodes, ring networks may be disrupted by the failure of a single link. A node failure or cable break might isolate every node attached to the ring. FDDI networks overcome this vulnerability by sending data on a clockwise and a counterclockwise ring: in the event of a break data is wrapped back onto the complementary ring before it reaches the end of the cable, maintaining a path to every node along the resulting "C-Ring". 802.5 networks -- also known as IBM Token Ring networks -- avoid the weakness of a ring topology altogether: they actually use a star topology at the physical layer and a Multistation Access Unit to imitate a ring at the datalink layer.
