Question 1

What is the TCP/IP transport layer responsible for?

Accepted Answer

End-to-end communication and reliability between applications

Answer

The transport layer (TCP/UDP) provides end-to-end communication between applications, handling reliable delivery and flow control.

Accepted Answer

Resolving IP addresses to MAC addresses on a local network

Answer

ARP (Address Resolution Protocol) maps a known IP address to the corresponding MAC address needed for local network communication.
