Q2). What does the engineering design process have in common with the scientific method discussed in a previous unit?
<u>Answer is:</u>
A). both have clearly defined steps.
<u>Explanation:</u>
While scientists study how nature works, engineers create new things, such as products, websites, environments, and experiences. Because engineers and scientists have different objectives, they follow different processes in their work. Scientists perform experiments using the scientific method; whereas, engineers follow the creativity-based engineering design process.
Both processes can be broken down into a series of steps.
I hope you get the idea.
Port 20 is ftp-data.
Port 21 is ftp.
Port 21 is the control channel. Port 20 is only used in Active mode. In Passive mode, port 20 isn't used, the data channel is established by the client to a high port number on the server. You can check RFC 873 for a LOT more info.
