Networking Protocols

TCP/IP - Abbreviation for Transmission Control Protocol/Internet Protocol, the suite of communications protocols used to connect hosts on the Internet. TCP/IP uses several protocols, the two main ones being TCP and IP. TCP/IP is built into the UNIX operating system and is used by the Internet, making it the de facto standard for transmitting data over networks. TCP/IP uses an IP address a series of numbers divided by a dot example 100.1.1.1.  TCP/IP is a connection oriented protocol.

Dial Up and Remote Access Networking Protocols

PPP Short for Point-to-Point Protocol, a method of connecting to a computer to the Internet PPP is more stable than the older SLIP protocol and provides error-checking features.

SLIP-Short for Serial Line Internet Protocol, a method of connecting to the Internet another more common method is PPP (Point-to-Point Protocol). SLIP is an older and simpler protocol, but from a practical perspective, there's not much difference between connecting to the Internet via SLIP or PPP. In general, service providers offer only one protocol although some support both protocols.

RAS – Dial up Protocol service use for connecting to a Microsoft Remote Access Server

PPPoE- Point to Point Protocol over Ethernet used for connecting multiple network users on an Ethernet LAN to a remote site through a common device. Very popular with DSL and wireless
