Document Summary

Computer uses dns to look up domain names. Path map to folder location where file is stored on server. Html: hypertext markup language: dns: domain name service. Internet directory service allows devices to be named and discoverable. Icann: internet corporation for assigning names and numbers: cybersquatting: acquiring a domain name that refers to a firm, person, product, or trademark, with goal of exploiting for financial gain. Tcp/ip: tcp(transmission control protocol)- like ae guaranteed mail service. Tcp makes sure all packets are there so you can receive the delivery. Make sure a perfect copy of a message is sent: packets: units of data forwarded by a network, all internet transmissions are divided into packets, tcp + router systems are scalable. Ip (internet protocol): routing protocol in charge of forwarding packets: routers: connects networks and exchanges data between them, udp (user datagram protocol): used instead of a tcp, if the message doesn"t have to be perfect.
