Does the TCP have it's own port number I don't understand this question could you guys help me out.
Which of the following protocols operates without a port number assignment?
A. SNMP
B. AFP
C. TCP
D. SSH

@@ismailakbar6449 tcp is the answer because it doesnt operate using a set of ports. TCP is a set of rules or standards

[@nehoha]

Just my 2 cents. This is only half explanation about the used ports. On both sides, local ports are getting assigned when the connection is being established. IP+Port = Socket. Two sockets are used for TCP communication. The server's listening port (80 in your example) is only used for establishing a connection by the client. After that the pair ServerIP:ServerLocalPort and ClientIP:ClientLocalPort are participating in the communication. These local ports are randomly assigned. This, I believe, needs to be explained in this video as well.

Excellent Explanation!

[@thereason1010]

Great explanation. Thanks sooo much!

[@archerline]

good video, the only thing missed was writing out the colon and port number next to the ip to wrap it up

this was awesome, thankyou

[@navneetkrishnasrivastava9521]

Well explained...Thank you!!!

[@riskexperts]

very good explanation. thank you

[@drygordspellweaver8761]

Can you expand on remote ports vs local? Say I want an inbound rule for windows defender to accept all connections addressed with port 1234... should that be the local port or remote?

[@davidsenneker7260]

So if u get this right, every port has its own task. Like you said 1001 till 1005 is used for the website for example. So how do i know what port are used by my Xbox for example? I want to open the ports, and i have to add new "command" in the list if you know what i mean..so is there a way to check this?

Hey that was really useful.

[@ariakelatwang4312]

Thanks for the example..

[@mikea-111]

Good explanation thanks. But did you just redefine numbers? 10003 is not one thousand and three. It is ten thousand and three.

[@benedictsimpson6953]

What I'm curious about are ports say between two site to site VPN connections. My guess is they would be listening on the one port only at both ends to keep the tunnel for eg. Openvpn using 1184 only on both sides? so I'm assuming here that no Ephemeral ports are used at all? does anyone know for sure? thanks

http on 80 is just convention or is it possible to set it to 25?

THANK YOU

[@redluck01]

I always explain it by telling people that the IP gets you to the machine then the port gets you to that individual application on that machine. I work on IBM mainframes so we have hundreds of applications on one machine which requires hundreds of ports on one machine.

[@jacobnsh]

Could it be used for malicious activities?
