Geography

Geography is the study of the earth and its features and of the circulation of life on the Earth. A literal transformation would be "to describe the Earth". The first person to use the word "geography" was Eratosthenes (275-195 B.C.). Four historical civilization in geographical research are the spatial analysis of natural and human phenomena, area studies, study of man-land relationship, and investigate in earth sciences. Nonetheless, modern geography is an all-inclusive discipline that foremost seeks to understand the world and all of its human and natural complexities-- not merely where things are, but how they have changed and come to be. It is said to be the "mother of all math" and "the synthesizer of information." Geography is mainly divided into two main branches - human geography and physical geography.

conventionally, geography as well as geographers has been viewed as the same as cartography and people who study place names. Although many geographers are capable in toponymy and cartography, this is not their main preoccupation. Geographers study the spatial and temporal allotment of phenomena, processes and feature as well as the interaction of humans and their environment. As space and place persuade a variety of topics such as economics, health, climate, plants and animals, geography is highly interdisciplinary.

Sports

Sport is an activity to facilitate is governed by a set of rules or customs and frequently engaged in competitively. Used by itself, sports generally refer to activities where the physical capabilities of the participant are the sole or primary determiner of the outcome, but the term is also used to comprise activities such as mind sports and motor sports where psychological acuity or equipment quality are major factors. Sports are used as hobby for the player and the viewer. It has also proved by experiments that daily exercise would boost mental strength and power to study.

Sports have been ever more organized and keeping pace from the time of the Ancient Olympics up to the present century. Industrialization has brought improved leisure time to the citizens of developed and developing countries, leading to more time for people to be present at and follow spectator sports, greater contribution in athletic activities, and increased accessibility. These trends continued with the beginning of mass media and global statement.

Currency

It is a form of money, where money is an capable medium of exchange, and it is also considered by a number of people as a store of value, created through a claim to its central bank assets. A currency zone is a country in which a specific currency is the main medium of exchange. To facilitate trade between currency zones, there are exchange price at which currencies can be exchanged beside each other. Currencies can be classified as also floating currencies or fixed currencies based on their exchange rate regime.

In general usage, currency at times refers to only paper money, as in "coins and currency", but this is confusing. Coins and paper money are both forms of currency.

In most cases, each country has control over the supply and manufacture of its own currency.

Computer Networking

Computer networking is the engineering discipline anxious with communication between computer systems. Such communicate systems comprise a computer network and these networks generally involve at least two devices able of being networked with at least one usually being a computer. The devices can be separated by a small number of meters or nearly unlimited distances. Computer networking is sometimes considered a sub-discipline of telecommunications, and sometimes of computer science, information technology and computer engineering. Computer networks rely a lot upon the abstract and practical application of these scientific and engineering disciplines.

A computer network is any set of computers connected to each other. Examples of networks are the Internet, a wide area network that is the largest to always exist, or a little home local area network (LAN) with two computers connected with standard networking cables connecting to a network interface card in each computer.
