What are the Exploits of Metasploit?
From Vulnerability Scanner, it is identified that the machine used of testing is vulnerable to FTP service. To use the exploit that works, the command is:
use “exploit path”
Then type mfs> show options to check for the parameters to be set to make functional. RHOST is set as the “target IP”.
Type msf> set RHOST 192.168.1.101 and msf>set RPORT 21.

What is Metasploit Payloads?
The scripts that hackers use to interact with hacked system are payloads. Payloads are used by hackers to transfer data to a victim system.
Metasploit payloads can be of three types :
Singles − Singles are very small and designed to create some kind of communication, then move to the next stage. For example, just creating a user.
Staged − It is a payload that an attacker can use to upload a bigger file onto a victim system.
Stages − Stages are payload components that are downloaded by Stagers modules. The various payload stages provide advanced features with no size limits such as Meterpreter and VNC Injection.
