A (a) is a container in which data is transmitted over networks
When a packet is sent through a network, it usually has to pass through a number of (a) before reaching its destination.
A router uses the recipient address on a packet to determine where to send the packet. Every time that a packet passes through a router, a (a) is said to occur.
Each packet can only pass through a finite number of hops. A packet’s (a) is a number that indicates how many hops the packet can partake in and is reduced by one with each hop
Two types of network device, ________ and ________, both perform essentially the same job. They connect different networks, allowing packets to reach their destination
(a)
Gateways are similar to routers, but they connect networks using different (a)
Reorder the following
data broken down into packet
source/destination (address) is added to each packet
packets routed independently
request for corrupted packets to be resent
packets reassembled into message at destination
Draw a simple diagram showing how a packet might travel across the internet
