what does SFTP stand for

secure file transfer protocol

what's the purpose of SFTP

provide excellent security when receiving and sending files

what are the requirements to use SFTP

connect to a SFTP server, one open port to send + receive

what's different about SFTP from other FTP protocols

needs only one port and packet-based instead of text-based (faster)

what's the purpose of NAT

provides private IP networks accessibility to the internet and the cloud. it translates private IP to public IP addresses

what does TFTP stand for

trivial file transfer protocol

what's the purpose of TFTP

what does the FC mean infront of an ipv6 address (ex: FC00::/7)
