Carnivore

A carnivore /ˈkɑːrnɪvɔər/ meaning 'meat eater' (Latin, caro meaning 'meat' or 'flesh' and vorare meaning 'to devour') is an organism that derives its energy and nutrient requirements from a diet consisting mainly or exclusively of animal tissue, whether through predation or scavenging. Animals that depend solely on animal flesh for their nutrient requirements are called obligate carnivores while those that also consume non-animal food are called facultative carnivores.Omnivores also consume both animal and non-animal food, and apart from the more general definition, there is no clearly defined ratio of plant to animal material that would distinguish a facultative carnivore from an omnivore. A carnivore that sits at the top of the foodchain is termed an apex predator.

Plants that capture and digest insects (and, at times, other small animals) are called carnivorous plants. Similarly, fungi that capture microscopic animals are often called carnivorous fungi.

Classification

The word "carnivore" sometimes refers to the mammalian order Carnivora, but this is somewhat misleading. While many Carnivora meet the definition of being meat eaters, not all do, and even fewer are true obligate carnivores (see below). For example, most species of bears are actually omnivorous, except for the giant panda, which is almost exclusively herbivorous, and the exclusively meat-eating polar bear, which lives in the Arctic, where few plants grow. In addition, there are plenty of carnivorous species that are not members of Carnivora.

Carnivore (software)

Carnivore, later renamed DCS1000, was a system implemented by the Federal Bureau of Investigation that was designed to monitor email and electronic communications. It used a customizable packet sniffer that can monitor all of a target user's Internet traffic. Carnivore was implemented in October 1997. By 2005 it had been replaced with improved commercial software such as NarusInsight.

Development

Carnivore grew out of an earlier FBI project called "Omnivore", which itself replaced an older surveillance tool migrated from the US Navy by FBI Director of Integrity and Compliance, Patrick W. Kelley, which had a still undisclosed name. In September 1998, the FBI's Data Intercept Technology Unit (DITU) in Quantico, Virginia, launched a project to migrate Omnivore from Sun's Solaris operating system to a Windows NT platform. This was done to facilitate the miniaturization of the system and support a wider range of personal computer (PC) equipment. The migration project was called "Phiple Troenix" and the resulting system was named "Carnivore."

DATAR

DATAR, short for Digital Automated Tracking and Resolving, was a pioneering computerized battlefield information system. DATAR combined the data from all of the sensors in a naval task force into a single "overall view" that was then transmitted back to all of the ships and displayed on plan-position indicators similar to radar displays. Commanders could then see information from everywhere, not just their own ship's sensors.

Development on DATAR was started by the Royal Canadian Navy in partnership with Ferranti Canada (later known as Ferranti-Packard) in 1949. The system proved too costly for the post-war Navy to develop alone, and when the Royal Navy and the United States Navy declined to share in the program it was ended. Both would then go on to start development of similar systems to fill this same role, the RN's Comprehensive Display System and the USN's Naval Tactical Data System.

History

In 1948, the Canadian Defence Research Board (DRB) sent a letter to various Canadian electronics firms informing them of their intention to start a number of projects that would partner the military, academia and private companies. A copy of the letter was sent to Ferranti Canada, then a small distributor of Ferranti's United Kingdom electrical equipment. The letter was forwarded to the then-CEO of Ferranti in the UK, Vincent Ziani de Ferranti, who became excited at the prospect of enlarging their Canadian operations largely funded by the government. At a meeting in October 1948 de Ferranti was disappointed to learn that while the DRB was equally excited, the amount of money they had to offer was basically zero.
