In this
fast moving world information technology has become a must. Information refers
to facts and opinions provided and received during the course of daily life.
Information is obtained from mass medica from electronic data banks, from all
sorts of observable phenomena in the surrounding environment, daily discourse
and body language.
Ours is
an increasingly knowledge-intensive environment. Knowledge plays a vital role
in such an environment. The growing volume and the rate of obsolescence of
knowledge makes it essential for an individual in the present day world to have
frequent interaction with informaiton resources and systems. Individuals cannot
ignore its impact on their skills and jobs.
Informaiton
technology makes obsolete many human functions. Earlier machanical and
repetitive tasks were affected. Now clerical and paraprofessional tasks are
being automated. The first three landset satellites were launched in 1972, 1975
and 1978 to collect information about Earth’s natural resources, location of
mineral deposits, condition of forests and farming regions. The cameras that
they carried provided images fo the surface areas. The fourth landsat satellite
was launched in 1982 and the fifth in 1984. Satellites are continued to be sent
by various countries to gather more information from space beneficial to
humanity.
One of
the greatest advances in modern technology has been the invention of computers.
Computer based information systems impact the structure and management styles
of corporation. Computers are widely used in industry and in universities. Now
there is hardly any sphere of human life where computers have not been pressed
into the service of man. They are capable of doing extremely complicated work
in all branches of learning. These machines can be put to varied uses. They can
provide information on the best way to prevent traffic accidents. They work
accurately and at high speeds, they save research workers, years of hard work.
The process of machines working for us in automation. Computer can be plugged
into a national network and be used like radios. Weather conditions could be
got, it could be used in ordinary public hospitals to diagnose the nature of
patients, illness, check their health record. Book keepers and accountants
could be relieved of dull clerical work.
The
tedious task of compiling and checking lists of figures could be done. It helps
scientists to solve complex problems in space science and launching of rockets
and satellites. It eliminates the work of filing records. Now, robotsmachine
men which are controlled by comptuers do tremendous work.
Thus
Radio, Television, Computers, Telephone, Telegraph etc. which are the products
of Technology have made life easier. It is we who have to reform our throughts
and use science and technology for the well being of the country.
