Information Technology

Information technology (IT), is the study, design, development, implementation, support or administration of computer-based information systems, particularly software applications and computer hardware.In short, IT deals with the use of electronic computers and computer software to transfer, store, protect, process, transmit and get back information, securely.

In this definition, the term "information" can frequently be replaced by "data" without loss of meaning. Recently it has become popular to widen the term to explicitly consist of the field of electronic communication so that people tend to use the abbreviation ICT (Information and Communication Technology). Strictly speaking, this name contains some redundancy.

Today, the term Information Technology has distended to encompass many aspects of computing and technology, and the term is more identifiable than ever before. The Information Technology umbrella can be quite large, covering many fields. IT professionals achieve a variety of duties that range from installing applications to designing complex computer networks and information databases.

Health

Health is the altitude of functional and/or metabolic effectiveness of an organism at both the micro(cellular) and macro(social) level. In the medical field, health is commonly defined as an organism's capability to efficiently respond to challenges (stressors) and effectively restore and sustain a "state of balance," known as homeostasis.

Another widely conventional definition of health is that of the World Health Organization (WHO), which states that "health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity". In more current years, this statement has been modified to include the ability to lead a "socially and economically industrious life." The WHO definition is not without criticism, as some argue that health cannot be defined as a state at all, but must be seen as a process of unremitting adjustment to the varying demands of living and of the changing meanings we give to life. The WHO definition is therefore considered by many as an idealistic goal rather than a realistic proposition.

An increasing measure of the health of populations is tallness, which is strongly synchronized by nutrition and health care, among other standard of living and quality of life matters. The study of human growth, its regulators and its implications is known as auxology.

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.
