A computer network diagram is a schematic depicting the nodes and connections amongst nodes in a computer network or, more generally, any telecommunications network ...
Route table showing internet BGP routes . In computer networking, a routing table, or routing information base (RIB), is a data table stored in a router or a network host that lists the routes to particular network destinations, and in some cases, metrics (distances) associated with those routes.
A router [a] is a computer and networking device that forwards data packets between computer networks, including internetworks such as the global Internet. [ 2 ] [ 3 ] [ 4 ] A router is connected to two or more data lines from different IP networks .
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.
Network mapping discovers the devices on the network and their connectivity. It is not to be confused with network discovery or network enumeration which discovers devices on the network and their characteristics such as operating system, open ports, listening network services, etc. The field of automated network mapping has taken on greater ...
A local area network (LAN) is a computer network that interconnects computers within a single physical location. It is the most common type of computer network, used in homes and buildings including offices or schools, [ 1 ] [ 2 ] [ 3 ] for sharing data and devices between each other, including Internet access .
A routing protocol specifies how routers communicate with each other to distribute information that enables them to select paths between nodes on a computer network. Routers perform the traffic directing functions on the Internet; data packets are forwarded through the networks of the internet from router to router until they reach 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.
