A network's physical topology is a particular concern of the physical layer of the OSI model. Examples of network topologies are found in local area networks , a common computer network installation. Any given node in the LAN has one or more physical links to other devices in the network; graphically mapping these links results in a geometric ...
An internetwork is the connection of multiple different types of computer networks to form a single computer network using higher-layer network protocols and connecting them together using routers. The Internet is the largest example of internetwork. It is a global system of interconnected governmental, academic, corporate, public, and private ...
The weak topology of a CW complex is defined as a direct limit. Let X {\displaystyle X} be any directed set with a greatest element m {\displaystyle m} . The direct limit of any corresponding direct system is isomorphic to X m {\displaystyle X_{m}} and the canonical morphism ϕ m : X m → X {\displaystyle \phi _{m}:X_{m}\rightarrow X} is an ...
The topology of a flat network is not segmented or separated into different broadcast areas by using routers. Some such networks may use network hubs or a mixture of hubs and switches, rather than switches and routers, to connect devices to each other. Generally, all devices on the network are a part of the same broadcast area.
In link-state routing protocols, each router possesses information about the complete network topology. Each router then independently calculates the best next hop from it for every possible destination in the network using local information of the topology. The collection of best next hops forms the routing table.
In mathematics, a topological space is, roughly speaking, a geometrical space in which closeness is defined but cannot necessarily be measured by a numeric distance.More specifically, a topological space is a set whose elements are called points, along with an additional structure called a topology, which can be defined as a set of neighbourhoods for each point that satisfy some axioms ...
The Bekenstein bound limits the amount of information that can be stored within a spherical volume to the entropy of a black hole with the same surface area. Thermodynamics limit the data storage of a system based on its energy, number of particles and particle modes. In practice, it is a stronger bound than the Bekenstein bound.
An illustration of hops in a wired network (assuming a 0-origin hop count [1]). The hop count between the computers in this case is 2. In wired computer networking a hop occurs when a packet is passed from one network segment to the next. Data packets pass through routers as they travel between source and destination.
