👉 TCP sounds, also known as "ping" or "traceroute," simulate the TCP handshake process and are used to test network connectivity by sending an ICMP Echo Request packet with a specific TCP sequence number (usually 5000) back to the destination along with its own sequence number. These sounds help identify whether packets can be transmitted over a network path without significant delays or loss, effectively checking if devices in the local network and beyond can communicate using TCP.
