Raspberry Pi

A series of small single-board computers developed in the United Kingdom by the Raspberry Pi Foundation to promote the teaching of basic computer science in schools and in developing countries. The original model became far more popular than anticipated, selling outside of its target market for uses such as robotics.


The number of people who actually saw your ad.

Regulatory Sandboxes

An online advertising strategy that involves serving website visitors advertisements based on their prior Internet use. Retargeting allows a company to connect with a website visitor who has left the site without making a purchase. The strategy involves using cookies, which the website puts on the visitor’s hard disk so that it can remember something about the visitor at a later time.

RFID — Radio Frequency Identification

A technology that incorporates the use of electromagnetic or electrostatic coupling in the radio frequency (RF) portion of the electromagnetic spectrum to uniquely identify an object, animal, or person. RFID is coming into increasing use in industry as an alternative to the bar code. The advantage of RFID is that it does not require direct contact or line-of-sight scanning. An RFID system consists of three components: an antenna and transceiver (often combined into one reader) and a transponder (the tag). The antenna uses radio frequency waves to transmit a signal that activates the transponder. When activated, the tag transmits data back to the antenna. The data is used to notify a programmable logic controller that an action should occur.

RPA — Robotic Process Automation

Software robots that replicates the actions of a human being interacting with the human user interface (keyboard and mouse of a computer). Used for data entry or full end-to-end business processing. The key is the robot uses the User Interface (UI) rather than an API  to execute steps in a manner identical to a human being. Thus, this process does not require IT resources for coding and development, as the automation is created by non-technical business users who train (configure)m the robot in an intuitive manner akin to how one employee trains another employee.

RSS Feed — Rich Site Stream Feed

A type of web feed which allows users to access updates to online content in a standardized, computer-readable format. These feeds can, for example, allow a user to keep track of many different websites in a single news aggregator. The news aggregator will automatically check the RSS feed for new content, allowing the content to be automatically passed from website to website or from website to user. This passing of content is called web syndication. Websites usually use RSS feeds to publish frequently updated information, such as blog entries, news headlines, audio, video. An RSS document (called "feed", "web feed" or "channel") includes full or summarized text, and metadata, like publishing date and author’s name

ROAS — Return On Ad Spend

Return on advertising spend, or ROAS is a term used in the advertising community to describe the profits made by and attributable to advertising campaigns. This calculation measures the effectiveness of marketing campaigns. Formula for ROAS: Revenue / Cost = ROAS. Divide the revenue that is driven by advertising by the amount that is spent on that advertising to arrive at this amount.
