First demonstrated in 1973, it was developed to explore alternatives to the early ARPANET design and to support network research generally. It was the first network to use the end-to-end principle and make the hosts responsible for reliable delivery of data, rather than the network itself.
Inter-network routing and global addressing are higher-layer functions, allowing data-link protocols to focus on local delivery, addressing, and media arbitration. In this way, the data link layer is analogous to a neighborhood traffic cop; it endeavors to arbitrate between parties contending for access to a medium, without concern for their ...
eth0 is the interface name of the network interface card representing an Ethernet port. ppp0 is a PPPoE interface, which is configured as the default route in this example. A default route is recognized by the destination 0.0.0.0 and the flag G. A network router is identified by the network mask 255.255.255.255 and the flag H.
A network is a medium to which many nodes can be connected, on which every node has an address and which permits nodes connected to it to transfer messages to other nodes connected to it by merely providing the content of a message and the address of the destination node and letting the network find the way to deliver the message to the ...
While IPv4 uses 32 bits for addressing, yielding c. 4.3 billion (4.3 × 10 9) addresses, IPv6 uses 128-bit addresses providing c. 3.4 × 10 38 addresses. Although adoption of IPv6 has been slow, as of January 2023 [update] , most countries in the world show significant adoption of IPv6, [ 10 ] with over 41% of Google's traffic being carried ...
Routing is the process of selecting a path for traffic in a network or between or across multiple networks. Broadly, routing is performed in many types of networks, including circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet.

The channel access control mechanism relies on a physical layer multiplex scheme. The most widespread multiple access method is the contention-based CSMA/CD used in Ethernet networks. This mechanism is only utilized within a network collision domain, for example, an Ethernet bus network or a hub-based star topology network.
