Can you list the main protocols used for data transmission in networks?

The main protocols used for data transmission in networks include:

• TCP (Transmission Control Protocol) — provides reliable, connection-oriented data transfer.
• UDP (User Datagram Protocol) — provides connectionless transfer, faster but without delivery guarantees.
• HTTP/HTTPS — protocols for transmitting hypertext on the internet, HTTPS with encryption.
• FTP (File Transfer Protocol) — for transferring files between a client and a server.
• SMTP (Simple Mail Transfer Protocol) — for sending emails.
• IP (Internet Protocol) — the main network layer protocol for routing packets.

These protocols often work together, for example, HTTP over TCP/IP.
