The ARPA Services
The ARPA services are a subset of the networking services originally developed by the
University of California at Berkeley for the Advanced Research Projects Agency (ARPA).
ARPA services have become a de facto standard for multivendor network communication.
FTP
FTP is an ARPA Service that allows users to transfer files among other networked
systems. FTP is the file transfer program that uses the ARPA standard File Transfer
Protocol (FTP). With FTP, you can also perform file management operations.
FTP is based on the client-server model as shown in Figure 1-1.. An FTP user on a system
(the client) accesses the remote host FTP server to perform FTP tasks. FTP conforms to
the de-facto industry standards RFC959 and RFC1123.
