1. a. Scp is the "Secure Copy" program and it works just like the "cp", or "Copy" program, only it works through via the Secure Shell.
Ftp is the "File Transfer Protocol" and has nothing to do with security. Usually operates as its own interface with its own set of user sub-commands.
Both are used to transfer files from one host to another via network connection
b. Telnet is a terminal emulator application. A terminal emulator lets users on one computer see the command line of another computer as though the actions displayed on the screen were happening on the local computer. SSH is called Secure Shell. It is also a terminal emulator
c. rsh and ssh are similar in that they can execute commands on remote systems. The main difference between the two (besides the actual TCP ports) is that rsh traffic is not encrypted and therefore a security risk; ssh traffic is encrypted
