Introduction
Computer is an electronic
device that can receive a set of instructions, or program, and then carry
out this program by performing calculations on numerical data or by compiling
and correlating other forms of refference modern world of high technology
could not have come about except for the development of the computer. Different
types and sizes of computers find uses throughout society in the storage
and handling of data, from secret governmental files to banking transactions
to private household accounts. Computers have opened up a new era in manufacturing
through the techniques of automation, and they have enhanced modern communication
systems. They are essential tools in almost every field of research and
applied technology, from constructing models of the universe to producing
tomorrow's weather reports, and their use has in itself opened up new areas
of conjecture. Database services and computer networks make available a
great variety of information sources. The same advanced techniques also
make possible invasions of privacy and of restricted information sources,
but computer crime has become one of the many risks that society must face
if it would enjoy the benefits of modern technology.
