Ural (computer)

Ural is a series of mainframe computers built in the former Soviet Union.

History

The Ural was developed at the Electronic Computer Producing Manufacturer of Penza in the Soviet Union and was produced between 1959 and 1964. In total 139 were made. The computer was widely used in the 1960s, mainly in the socialist countries, though some were also exported to Western Europe and Latin America.

When the University of Tartu received a new computer, its old computer, the Ural 1, was moved to a science biased secondary school, the Nõo Reaalgümnaasium. That event took place in 1965 and made the Nõo Reaalgümnaasium the very first secondary school in the Soviet Union to own its very own computer.

Attributes

Models Ural-1 to Ural-4 were based on vacuum tubes (valves), with the hardware being able to perform 12,000 floating-point calculations per second. One word consisted of 40 bits and was able to contain either one numeric value or two instructions. Ferrite core was used as operative memory. A new series (Ural-11, Ural-14, produced between 1964 and 1971) was based on semiconductors.

Ural (region)

The Urals (Russian: Ура́л) are a geographical region located around the Ural Mountains, between the East European and West Siberian plains. It extends approximately from north to south, from the Arctic Ocean to the bend of Ural River near Orsk city. The boundary between Europe and Asia runs along the eastern side of the Ural Mountains. Ural mostly lies within Russia but also includes a part of northwestern Kazakhstan. This is a historical, not an official entity, with the boundaries overlapping its western Volga and eastern Siberia neighbor regions. At points in time, parts of the Urals were considered a gateway to Siberia, if not Siberia itself, or were combined with the Volga administrative divisions. At present time, there are two official namesake entities, the Ural Federal District and the Ural economic region. While the latter follows the historical boundaries, the former is a political product; the District omits Western Urals and includes Western Siberia instead.

The historical center of the Urals is Cherdyn, nowadays it is the small town in Perm Krai. Perm was an administrative center of the gubernia with the same name by 1797. The most territory of historical and modern Ural was included in Perm gubernia. The administrative center of Urals was moved to Sverdlovsk (nowadays Yekaterinburg) after Revolution and Civil war. Nowadays Ural economic region does not have an administrative and informal capital, whereas Yekaterinburg is administrative center of the Ural Federal District.

Ural (rural locality)

Ural (Russian: Ура́л) is the name of several rural localities in Russia:

Computer

A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem.

Conventionally, a computer consists of at least one processing element, typically a central processing unit (CPU), and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit can change the order of operations in response to stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved.

Mechanical analog computers started appearing in the first century and were later used in the medieval era for astronomical calculations. In World War II, mechanical analog computers were used for specialized military applications such as calculating torpedo aiming. During this time the first electronic digital computers were developed. Originally they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).

List of Courage the Cowardly Dog characters

This is a list of characters from the Cartoon Network animated series, Courage the Cowardly Dog.

Main characters

Courage

Courage is the series' protagonist, and an overly frightened purple beagle dog who lives in Nowhere, Kansas. He was abandoned as a puppy after his parents were sent into outer space, but was adopted by Muriel Bagge. Her husband, Eustace, regularly mistreats him. Ironically, given his name, Courage is a genuine coward, but still goes to great lengths to protect his owners; to the end, he often gets injured, sometimes quite brutally, or almost killed and only surviving through his determination and/or pure luck. Despite his cowardice, Courage is very clever and resourceful when the situation demands it, outsmarting the villains most of the time. Aiding him at saving the day is a self-aware, sarcastic and seemingly omniscient Computer that he keeps in the attic with which he could consult for information in how to remedy any predicament he faces (though it never fails to badmouth him in one way or another). He got his name when Muriel found him as a puppy alone in an alley and remarked that he must be quite brave to be there by himself.

Computer (magazine)

Computer is an IEEE Computer Society practitioner-oriented magazine issued to all members of the society. It contains peer-reviewed articles, regular columns and interviews on current computing-related issues. The magazine can be categorized somewhere between a trade magazine and a research journal, drawing on elements of both. Computer provides information regarding current research developments, trends, best practices, and changes in the computing profession. Subscriptions of the magazine are provided free of cost to IEEE Computer Society members.

Computer covers all aspects of computer science. Since 2009, it has a digital edition too. The current editor is Sumi Helal of the University of Florida. Impact factor for 2013 was 1.438/
