Anetwork limit, called the can be placed on how many times any packet is copied.

hop limit

Explanation:

Hop limit (as called in IPV6), or Time to live (as called in IPV4) is one of the fields in data packet. It is used to limit the life time of a packet in a network by specifying the allowable limit on the number of hops for which a packet is allowed before being removed from the network. It prevents a network from holding a packet forever. So when a router receives a packet, before forwarding it, it decrements the packet's hop limit by 1. If the hop limit gets to zero, any router holding it will drop it rather than forwarding it. This will help remove the packet from the network.

a macro is a tool that allows you to automate tasks and add functionality to your forms, reports, and controls. for example, if you add a command button to a form, you associate the button's onclick event to a macro, and the macro contains the commands that you want the button to perform each time it is clicked.
