Three categories of TCP/UDP port numbers

Today my topic is port number, three categories of port numbers, and some well-known port numbers we need to know for the National CompTIA Network+, Security+, and other tests
Port number is 16-bit values. 2^16, 2 to the 16th power is 65,536. The range of the port number is 0 to 65,535.
A port number defines a virtual port to a specific application or service running on a computer. A port number can define a virtual port to access a specific service on a server or a connection point on a client computer.

I think the TFTP is using UDP port 69 rather than TCP. at 5:50

[@Metalninja89]

Underrated comment, also DHCP uses UDP and not TCP

[@albertk3677]

Hello Sunny, I do not know if you are reading this but 67-69 = UDP. Greetings

Isn't ports 67 and 68 UDP, not TCP?

[@SecretAgentPaul]

correct

[@abdirahmanabdullahi1150]

What

[@clashingwithprolooters]

DHCP uses UDP instead of TCP, Sunny.

[@alexandredelode2913]

TCP/UDP should be checked on the last table "14 well known port"
