1.1. The Ethernet and PPP in data transfer.
There are different methods for the effective transfer of data between different nodes. Ethernet and Point-to-point protocol are two of them. Ether net can be defined as a family of computer networking technology used for local area networks (LAN). The functioning of Ethernet is based on a set of coding system which allows the coding violations to mark the frame boundaries. It also defines the network layer interfaces to the physical interconnects.

There are several important features and advantages for the Ethernet; but there are some disadvantages too. One of the disadvantages is - it will not operate on wide variety of media, which includes the async serial ports which are usually used with the dial up modems and synchronous telecom services. Using Ethernet, only on synchronous links, it will be able to use 100BASE-TX 4B/5B or 1000BASE- X 8B/10B encoding for making an Ethernet-like serial implication. And the result of this will be less efficient too.

Point-to point protocol is a commonly used data link protocol for establishing direct connection. The connection authentication, encryption, transcription and compression are provided in by the PPP. The PPP is used in many types of networks like phone line, cellular telephone, serial cable, specialized radio links and fiber optical links. The PPP which is used over the Internet access is called broadband. The most commonly used forms of PPP by the Internet service providers are
