The passage is not concerned with ____ .

Computers can store vast amounts of information in a
very small space and are used by the banks to keep
accounts, print out statements and control
transactions. They are also used by the police to keep
personal records, fingerprints and other details. In the
rapidly developing field of robotics computers are now
being used to control manual operations done by
mechanics. These, too, are taking over work,
previously done by people in the manufacture of cars,
in weaving and in other industries. Computers play an
important role in controlling artificial satellites,
decoding information and communications generally.
They are used to predict the weather with increasing
accuracy.
