Answer from AI
Main protocols of the TCP/IP stack and their functions:
-
IP (Internet Protocol) — responsible for addressing and routing data packets between network nodes.
-
TCP (Transmission Control Protocol) — provides reliable, connection-oriented data transfer, error checking, and delivery order.
-
UDP (User Datagram Protocol) — provides data transfer without establishing a connection, without delivery guarantees, but with lower latency.
-
ICMP (Internet Control Message Protocol) — used for transmitting control messages, such as network diagnostics (ping).
-
ARP (Address Resolution Protocol) — converts IP addresses to physical MAC addresses within a local network.
-
DNS (Domain Name System) — translates domain names into IP addresses.
-
HTTP/HTTPS (HyperText Transfer Protocol / Secure) — application layer protocols for transmitting web pages and resources.
Each of these protocols plays its role in ensuring network interaction, from routing and data transfer to name resolution and connection management.
