    Traditionally animation is produced by drawing illusion of movement created by photographing a series of individual drawings on successive frames on film. Greenberg (1997) explains, "Animation is a deliberately interpreted "illusion of life." It has been practiced for the last 70 years in both drawn and stop motion animation, and as such, is not an attempt to mimic human and animal life exactly." ... View full abstract»

    The current IP-based networks are described as best effort. When a packet arrives at a router, the router looks at the destination address, checks with the routing-table entries, then selects the best match and sends the packet to the output queue. The routing is dynamic where the packets in a single flow may take different paths to the destination. Also packets in the output queues are serviced b... View full abstract»
