How do the three-way handshake and Nmap's four different scanning modes affect port scanning? Outside the default port scan that comes with Nmap, are there any others worth trying?

Due to the vast number of devices connected to the terminals, the system requires a method that will enable it to communicate without perpetually prioritising the process of abnormality detection. Do we need to take anything else into account at this time?

How does Microchip's MPLAB IDE support the development of firmware for Microchip microcontrollers? Discuss its key features.

What is the relationship between the three-way handshake and Nmap's four different scanning modes when scanning ports? Is there a more efficient port scan method than Nmap's default that you might recommend?

Rather than always prioritizing the process of searching for anomalies, the system should be able to communicate with all the devices inserted into the ports. Is there anything else we need to be considering at this time?
