Information
Technology ( IT ) is a general term for any technology that helps people create,
modify , store , communicate and / or disseminate information . TI brings together high-speed computing and communications for data , voice , and video . Examples of Information Technology is not just a personal computer ,
but also a phone , TV , electronic home appliances , and modern handheld
devices ( eg mobile phones ) .
In a business context , Information Technology Association of America explains
Processing
, storage and dissemination of vocal , pictorial information , text and
numeric by a microelectronics -based combination of computing and
telecommunications . The term in its modern sense first appeared in a 1958 article
published in the Harvard Business Review , in which authors Leavitt and
Whisler commented that " the new technology does not yet have a single
established name . We'll call it information technology ( IT ) . " . Some of the modern and emerging fields of information technology
are next generation web technologies , bioinformatics , '' Cloud
Computing '' , global information systems , large -scale knowledge bases
, and others.
History
At the beginning of history , humans exchange information through language . So
language is technology , language allows one to understand the
information conveyed by others , but it did not survive long because
after the speech was finished , the information which is in the hands of
the recipient will be forgotten and can not be stored long . Besides voice coverage is also limited .
After the delivery of information technology evolve through pictures . With a range of images could be further information . This image can be carried and passed on to others . In addition there is information that would last longer . Some ancient relic images still exist today so that people now can ( try ) to understand the information to be conveyed maker.
The
discovery of the alphabet and arabic numbers facilitate the delivery of
information that is more efficient than the previous method . An
image representing an event created by the combination of the alphabet ,
or by writing numbers , such MCMXLIII replaced by 1943 . This technology facilitates the alphabet in writing of the information .
Then , printing technology allows fast transmission of information over again . Electronic
technologies such as radio , television , computers become faster
resulting in information spread over a larger area and longer stored .
General information
IT
is the field of technology management and includes a variety of fields
including but not limited to things such as processes , computer
software , information systems , computer hardware , programming
languages , and data constructs . In
short , anything that renders data , information or perceived knowledge
in any visual format whatsoever , via any multimedia distribution
mechanism , is considered part of the IT . IT provides businesses with four sets of core services to help execute
the business strategy : business process automation , providing
information , connecting with customers , and productivity tools .
TI
perform a variety of functions ( IT Disciplines / Competencies ) from
installing applications to designing computer networks and information
databases . Some
tasks might include doing IT data management , networking , engineering
computer hardware , database and software design , as well as the
management and administration of entire systems . Information technology is starting to spread farther than the
conventional personal computer and network technology , and more into
the integration of technologies such as the use of cell phones ,
televisions , cars , and many more , which increases the demand for jobs
.
In
the past , the ( Accreditation Board for Engineering and Technology )
and the Association for computing machinery have collaborated to form
accreditation and curriculum standards for degrees in Information
Technology program as a field of study as compared with the
Computer Science and Information Systems . SIGITE ( Special Interest Group for IT Education ) is the ACM working group for defining these standards . IT services revenue worldwide amounted to $ 763 billion in 2009.
Growth and technological capacity
Hilbert and Lopez identify the exponential pace of technological change (a kind of Moore's law): machines' application-specific capacity to compute information per capita has roughly doubled every 14 months between 1986 to 2007; capacity per-capita in the world of computers destination general has doubled every 18 months over the same two decades, the global telecommunication capacity per capita doubled every 34 months; storage capacity per capita world that it takes about 40 months to double (every 3 years), and per capita broadcast information has doubled approximately every 12.3 years.
