MIS








Modern business is spurred on by technology and innovation. The driving force behind these two things is information and how it is used. For decades, business used information as a strategic tool to grow customer base, market share, cut costs and to gain the overall target of increased profits and efficiency. In the modern environment, information on its own isn't enough, what's required is a way to use this information properly, keep it secure and to make it accessible to the appropriate parties. To do this, a new strategic asset has been developed. The new asset is Information Technology and in the business context it's called Management Information Systems (MIS).

History of computer science

















The earliest known tool for use in computation was the abacus, and it was thought to have been invented in Babylon circa 2400 BCE. Its original style of usage was by lines drawn in sand with pebbles. This was the first known computer and most advanced system of calculation known to date - preceding Greek methods by 2,000 years. Abaci of a more modern design are still used as calculation tools today.
In
1115 BCE, the South Pointing Chariot was invented in ancient China. It was the first known geared mechanism to use a differential gear, which was later used in analog computers. The Chinese also invented a more sophisticated abacus from around the 2nd century BCE, known as the Chinese abacus.
In the
5th century BCE in ancient India, the grammarian Pāṇini formulated the grammar of Sanskrit in 3959 rules known as the Ashtadhyayi which was highly systematized and technical. Panini used metarules, transformations and recursions with such sophistication that his grammar had the computing power equivalent to a Turing machine. Between 200 BCE and 400 CE, Jaina mathematicians in India invented the logarithm. From the 13th century, logarithmic tables were produced by Muslim mathematicians.
The
Antikythera mechanism is believed to be the earliest known mechanical analog computer.[1] It was designed to calculate astronomical positions. It was discovered in 1901 in the Antikythera wreck off the Greek island of Antikythera, between Kythera and Crete, and has been dated to circa 100 BC.
Mechanical analog computer devices appeared again a thousand years later in the
medieval Islamic world and were developed by Muslim astronomers, such as the equatorium by Arzachel,[2] the mechanical geared astrolabe by Abū Rayhān al-Bīrūnī,[3] and the torquetum by Jabir ibn Aflah.[4] The first programmable machines were also invented by Muslim engineers, such as the automatic flute player by the Banū Mūsā brothers[5] and the humanoid robots by Al-Jazari.[6] Muslim mathematicians also made important advances in cryptography, such as the development of cryptanalysis and frequency analysis by Alkindus.[7][8]
When John Napier discovered logarithms for computational purposes in the early 17th century, there followed a period of considerable progress by inventors and scientists in making calculating tools.
None of the early computational devices were really
computers in the modern sense, and it took considerable advancement in mathematics and theory before the first modern computers could be designed.

A rubric is a word or section of text which is written or printed in red ink to highlight it. The term derives from the Latin: rubrica, meaning red ochre or red chalk,[1] and originates in Medieval illuminated manuscripts from the 13th century or earlier. In these, red letters were used to highlight initial capitals (particularly of psalms), section headings and names of religious significance, a practice known as rubrication, which was a separate stage in the production of a manuscript.
Rubric can also mean the red ink or paint used to make rubrics, or the
pigment used to make it.[2] Although red was most often used, other colours came into use from the late Middle Ages onwards, and the word rubric was used for these also.

Information Literacy









Several conceptions and definitions of information literacy have become prevalent. For example, one conception defines information literacy in terms of a set of competencies that an informed citizen of an information society ought to possess to participate intelligently and actively in that society (from [1]).
The
American Library Association's (ALA) Presidential Committee on Information Literacy, Final Report states that, "To be information literate, a person must be able to recognize when information is needed and have the ability to locate, evaluate, and use effectively the needed information" (1989).
Jeremy Shapiro & Shelley Hughes (1996) define information literacy as "A new liberal art that extends from knowing how to use computers and access information to critical reflection on the nature of information itself its technical infrastructure and its social, cultural, and philosophical context and impact." (from
[2])
Information literacy is becoming a more important part of K-12 education. It is also a vital part of university-level education (Association of College Research Libraries, 2007). In our information-centric world, students must develop skills early on so they are prepared for post-secondary opportunities whether that be the workplace or in pursuit of education.

Search Engine




http://en.wikipedia.org/wiki/Search_engine_optimization
is the process of improving the volume and quality of traffic to a web site from search engines via "natural" ("organic" or "algorithmic") search results. Usually, the earlier a site is presented in the search results, or the higher it "ranks," the more searchers will visit that site. SEO can also target different kinds of search, including image search, local search, and industry-specific vertical search engines.

History of the Internet


Prior to the widespread internetworking that led to the Internet, most communication networks were limited by their nature to only allow communications between the stations on the network, and the prevalent computer networking method was based on the central mainframe method. In the 1960s, computer researchers, Levi C. Finch and Robert W. Taylor pioneered calls for a joined-up global network to address interoperability problems. Concurrently, several research programs began to research principles of networking between separate physical networks, and this led to the development of Packet switching. These included Donald Davies (NPL), Paul Baran (RAND Corporation), and Leonard Kleinrock's MIT and UCLA research programs.
This led to the development of several packet switched networking solutions in the late 1960s and 1970s, including
ARPANET and X.25. Additionally, public access and hobbyist networking systems grew in popularity, including UUCP and FidoNet. They were however still disjointed separate networks, served only by limited gateways between networks. This led to the application of packet switching to develop a protocol for inter-networking, where multiple different networks could be joined together into a super-framework of networks. By defining a simple common network system, the Internet protocol suite, the concept of the network could be separated from its physical implementation. This spread of inter-network began to form into the idea of a global inter-network that would be called 'The Internet', and this began to quickly spread as existing networks were converted to become compatible with this. This spread quickly across the advanced telecommunication networks of the western world, and then began to penetrate into the rest of the world as it became the de-facto international standard and global network. However, the disparity of growth led to a digital divide that is still a concern today.
Following commercialisation and introduction of privately run
Internet Service Providers in the 1980s, and its expansion into popular use in the 1990s, the Internet has had a drastic impact on culture and commerce. This includes the rise of near instant communication by e-mail, text based discussion forums, the World Wide Web. Investor speculation in new markets provided by these innovations would also lead to the inflation and collapse of the Dot-com bubble, a major market collapse. But despite this, Internet continues to grow

Polar Bear
















The polar bear (Ursus maritimus) is a bear native to the Arctic Ocean and its surrounding seas. The world's largest predator found on land, an adult male weighs around 400–680 kg (880–1,500 lb),[3] while an adult female is about half that size. Although it is closely related to the brown bear, it has evolved to occupy a narrow ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice, and open water, and for hunting the seals which make up most of its diet.[4] As it can hunt consistently only from sea ice, the polar bear spends much of the year on the frozen sea, although most polar bears are born on land.






Naming and etymology




Constantine John Phipps was the first to describe the polar bear as a distinct species. He chose the scientific name Ursus maritimus, the Latin for 'maritime bear', due to the animal's native habitat. The Inuit refer to the animal as nanook[8], (transliterated as nanuuq in the Inupiat language[9], nanuuk in Siberian Yupik, and also as nanuq or nanuk[citation needed]; and hence the title of the early 20th century documentary on Inuit life, Nanook of the North). The bear is umka in the Chukchi language. In Russian, it is usually called Белый Медведь (Bely Medved, the White Bear), though an older word still in use is Ошкуй (Oshkuy, which comes from the Komi Oski, "bear").In Quebec French, the polar bear is referred to as Ours polaire.




Habitat




The polar bear is often regarded as a marine mammal because it spends many months of the year at sea.Its preferred habitat is the annual sea ice covering the waters over the continental shelf and the Arctic inter-island archipelagos. These areas, known as the "Arctic ring of life", have relatively high biological productivity in comparison to the deep waters of the high Arctic. The polar bear tends to frequent areas where sea ice meets water, such as polynyas and leads (temporary stretches of open water in Arctic ice), to hunt the seals that make up most of its diet.[26] Polar bears are therefore found primarily along the perimeter of the polar ice pack, rather than in the Polar Basin


close to the North Pole where the density of seals is low.
Annual ice contains areas of water that appear and disappear throughout the year as the weather changes. Seals migrate in response to these changes, and polar bears must follow their prey.In Hudson Bay, James Bay, and some other areas, the ice melts completely each summer (an event often referred to as "ice-floe breakup"), forcing polar bears to go onto land and wait through the months until the next freeze-up. In the Chukchi and Beaufort seas, polar bears retreat each summer to the ice further north that remains frozen year-round.




Behavior




Unlike grizzly bears, polar bears are not territorial. Although stereotyped as being voraciously aggressive, they are normally cautious in confrontations, and often choose to escape rather than fight.Fat polar bears rarely attack humans unless severely provoked, whereas hungry polar bears are extremely unpredictable and are known to kill and sometimes eat humans.Polar bears are stealth hunters, and the victim is often unaware of the bear's presence until the attack is underway. Whereas brown bears often maul a person and then leave, polar bear attacks are almost always fatal.
In general, adult polar bears live solitary lives. Yet, they have often been seen playing together for hours at a time and even sleeping in an embrace, and polar bear zoologist Nikita Ovsianikov has described adult males as having "well-developed friendships." Cubs are especially playful as well. Among young males in particular, play-fighting may be a means of practicing for serious competition during mating seasons later in life.
In 1992, a photographer near Churchill took a now widely-circulated set of photographs of a polar bear playing with a Canadian Eskimo Dog a tenth of its size. The pair wrestled harmlessly together each afternoon for ten days in a row for no apparent reason, although the bear may have been trying to demonstrate its friendliness in the hope of sharing the kennel's food.This kind of social interaction is uncommon; it is far more typical for polar bears to behave aggressively towards dogs.




Global warming



The IUCN, Arctic Climate Impact Assessment, United States Geological Survey and many leading polar bear biologists have expressed grave concerns about the impact of global warming, including the belief that the current warming trend imperils the survival of the species.
The key danger posed by global warming is malnutrition or starvation due to habitat loss. Polar bears hunt seals from a platform of sea ice. Rising temperatures cause the sea ice to melt earlier in the year, driving the bears to shore before they have built sufficient fat reserves to survive the period of scarce food in the late summer and early fall.Reduction in sea-ice cover also forces bears to swim longer distances, which further depletes their energy stores and occasionally leads to drowning.Thinner sea ice tends to deform more easily, which appears to make it more difficult for polar bears to access seals.Insufficient nourishment leads to lower reproductive rates in adult females and lower survival rates in cubs and juvenile bears, in addition to poorer body condition in bears of all ages.
In addition to creating nutritional stress, a warming climate is expected to affect various other aspects of polar bear life: Changes in sea ice affect the ability of pregnant females to build suitable maternity dens. As the distance increases between the pack ice and the coast, females must swim longer distances to reach favored denning areas on land. Thawing of permafrost would affect the bears who traditionally den underground, and warm winters could result in den roofs collapsing or having reduced insulative value. For the polar bears that currently den on multi-year ice, increased ice mobility may result in longer distances for mothers and young cubs to walk when they return to seal-hunting areas in the spring.Disease-causing bacteria and parasites would flourish more readily in a warmer climate.
Problematic interactions between polar bears and humans, such as foraging by bears in garbage dumps, have historically been more prevalent in years when ice-floe breakup occurred early and local polar bears were relatively thin.Increased human-bear interactions, including fatal attacks on humans, are likely to increase as the sea ice shrinks and hungry bears try to find food on land.
