Week 7 - Routing Table

Routers handle a lot of information and need ways to store data. One of the main ways this is done is through a routing table. A routing table itself is stored on the RAM that a router uses that has information about direct connections and remote networks. The way routing occurs is by having packets come into the queue that are then stripped off Layer 2. The order in which the packet is handled is based on the arrival time. The router then works to inspect the packet's destination IP address and sends the IP on its way to the necessary port. Routing Tables handle this inspection process. The routing table has 4 pieces of information on the entry list: Destination LAN IP, Subnet Mask, Gateway, and Interface. Routers use the information that comes from the LAN IP and subnet to make sure the packet matches the correct route. This information gives a general idea of how routing tables pull information and what they deal with in networking.
