Token bucketThe token bucket is an algorithm used in packet-switched and telecommunications networks. It can be used to check that data transmissions, in the form of packets, conform to defined limits on bandwidth and burstiness (a measure of the unevenness or variations in the traffic flow). It can also be used as a scheduling algorithm to determine the timing of transmissions that will comply with the limits set for the bandwidth and burstiness: see network scheduler.
Internet layerThe internet layer is a group of internetworking methods, protocols, and specifications in the Internet protocol suite that are used to transport network packets from the originating host across network boundaries; if necessary, to the destination host specified by an IP address. The internet layer derives its name from its function facilitating internetworking, which is the concept of connecting multiple networks with each other through gateways.
Ad blockingAd blocking or ad filtering is a software capability for blocking or altering online advertising in a web browser, an application or a network. This may be done using browser extensions or other methods. The first ad blocker was Internet Fast Forward, a plugin for the Netscape Navigator browser, developed by PrivNet and released in 1996. The AdBlock extension for Firefox was developed in 2002, with Adblock Plus being released in 2006. uBlock (now called uBlock Origin) was first released in 2014.
Rich Internet ApplicationA Rich Internet Application (also known as a rich web application, RIA or installable Internet application) is a web application that has many of the characteristics of desktop application software. The concept is closely related to a single-page application, and may allow the user interactive features such as drag and drop, background menu, WYSIWYG editing, etc. The concept was first introduced in 2002 by Macromedia to describe Macromedia Flash MX product (which later became Adobe Flash).
Exponential backoffExponential backoff is an algorithm that uses feedback to multiplicatively decrease the rate of some process, in order to gradually find an acceptable rate. These algorithms find usage in a wide range of systems and processes, with radio networks and computer networks being particularly notable. An exponential backoff algorithm is a form of closed-loop control system that reduces the rate of a controlled process in response to adverse events.
Gossip protocolA gossip protocol or epidemic protocol is a procedure or process of computer peer-to-peer communication that is based on the way epidemics spread. Some distributed systems use peer-to-peer gossip to ensure that data is disseminated to all members of a group. Some ad-hoc networks have no central registry and the only way to spread common data is to rely on each member to pass it along to their neighbors. The concept of gossip communication can be illustrated by the analogy of office workers spreading rumors.
GnutellaGnutella is a peer-to-peer network protocol. Founded in 2000, it was the first decentralized peer-to-peer network of its kind, leading to other, later networks adopting the model. In June 2005, Gnutella's population was 1.81 million computers increasing to over three million nodes by January 2006. In late 2007, it was the most popular file-sharing network on the Internet with an estimated market share of more than 40%.
Anchor textThe anchor text, link label or link text is the visible, clickable text in an HTML hyperlink. The term "anchor" was used in older versions of the HTML specification for what is currently referred to as the a element, or . The HTML specification does not have a specific term for anchor text, but refers to it as "text that the a element wraps around". In XML terms (since HTML is XML), the anchor text is the content of the element, provided that the content is text. Usually, web search engines analyze anchor text from hyperlinks on web pages.
Service discoveryService discovery is the process of automatically detecting devices and services on a computer network. This reduces the need for manual configuration by users and administrators. A service discovery protocol (SDP) is a network protocol that helps accomplish service discovery. Service discovery aims to reduce the configuration efforts required by users and administrators. Service discovery requires a common language to allow software agents to make use of one another's services without the need for continuous user intervention.
Google SearchGoogle Search (also known simply as Google or Google.com) is a search engine provided and operated by Google. Handling more than 3.5 billion searches per day, it has a 92% share of the global search engine market. It is the most-visited website in the world. Additionally, it is the most searched and used search engine in the entire world. The order of search results returned by Google is based, in part, on a priority rank system called "PageRank".
