Without a doubt, TCP/IP.
A protocol is a set of rules by which computers communicate with each other across a network. A protocol is a convention or standard that controls or enables the connection, communication, and data transfer between computing endpoints, and may be implemented by hardware, software or a combination of the two.
"HTTP" is the protocol used by web browsers to communicate with web servers.
an email protocol is a method by which a communication channel is established between two computers and email is transferred between them

TCP
It's a protocol that enables communication between computers and servers.
Computers use communication protocols to communicate with each other. Just as humans generally communicate with each other using a common language, computers must do the same. A protocol defines the language the computers will use and both computers must agree upon which protocol to use, via a standard "handshake" protocol -- a simple two-way communication that establishes a connection as well as the protocol that will be used for the actual communication. Only when both sides agree upon the actual protocol can communication begin. As technology develops, protocols must evolve. Thus we have seen many ways for computers and devices to communicate and interconnect with each other over the years, each with their own set of protocols, each suited to a specific or general task. In the past we've seen COM, LPT, Ethernet, USB, FireWire and, more recently, wireless devices. Ethernet and wireless provide the basic transport system between any two computers today and often work together using intermediate devices, including wireless routers (which are themselves just simple computers). Without a common protocol, communication between all these devices would be impossible. The most prevalent protocol in use today is TCP/IP, without which the internet would not work. TCP/IP is actually two separate protocols: Transmission Control Protocol and Internet Protocol, but they work together with a third protocol, UDP (user datagram protocol), to provide a multi-layered suite of protocols. The top layer, the application level, is further split into separate protocols including HTTP (hypertext transfer protocol), FTP (file transfer protocol), SMTP (simple mail transfer protocol), DNS (domain name server), RIP (routing information protocol), SNMP (simple network management protocol) and TELNET (terminal emulation protocol), amongst many others. All Internet-enabled devices must support TCP/IP version 4 (the current protocol), although most also support version 6 which is expected to become the standard protocol at some point in the future.
A protocol is a set of rules which is used by computers to communicate with each other across a network. A protocol is a convention or standard that controls or enables the connection, communication, and data transfer between computing endpoints. In its simplest form, a protocol can be defined as the rules governing the syntax, semantics, and synchronization of communication. Protocols may be implemented by hardware, software, or a combination of the two. At the lowest level, a protocol defines the behavior of a hardware connection.A technique is a procedure used to accomplish a specific activity or task.
Some users have reported Yahoo! Chat and Upnp as using these ports, but there doesn't seem to be an "official" use of port 5000.TCP Port 5000 may use a defined protocol to communicate depending on the application. A protocol is a set of formalized rules that explains how data is communicated over a network. Think of it as the language spoken between computers to help them communicate more efficiently.
Windows is better for desktop computers. Linux is better for servers.
No it does not.
Telnet is a protocol for transferring plain text over TCP .
