PROTOCOLS

Okay ..
What are protocols ?

As I've learned,
Protocols are the rules between computers on a network.
There are many kinds of protocols (I think, there 5 or 6).

Here they are :

1.  IP - Internet Protocol
2.  TCP - Transmission Control Protocol
3.  UDP - User Datagram Protocol
4.  FTP - File Transfer Protocol
5.  HTTP - Hypertext Transfer Protocol
6.  SMTP - Simple Mail Transfer Protocol

There are other protocols which are not commonly used like
ARP, ICMP, and DHCP.
