should be used for. EX: SMTP (email) uses port 25, while HTTP (normal web browsing) uses port 80
TCP - ANSWER✔✔-the data created into packets, which are then given a port/ packet number. IP adds
destination and return address. Go through routers to destination
routing table - ANSWER✔✔-Routers are programmed with instructions about where to send each packet
of data, depending on the destination's IP address. These instructions are often stored in a routing table.
Routers can judge, based on the initial
digits of an IP address, which direction packets need to be sent.
the router just sends the packet one step closer to the destination, and lets the next router
take care of the rest.

domain names
Dynamic Host Configuration Protocol - ANSWER✔✔-helps to assign each device an IP address. When
computers connect to a network, they will connect to a DHCP server. The DHCP server is able to access
a pool of available IP addresses, and the server is responsible for assigning each computer on the
network a
unique IP address.
