UNIT 1 : Computers Users
Make the World Smaller and Smarter
ability of tiny computing devices to control complex operations has transformed the way many tasks are performed, ranging
from scientific research to producing consumer products. Tiny ‘computers on a chip’ are used in medical equipment,
home appliances, cars and toys. Workers use hadheld computing devices to collect data at a customer site, to generate forms,
to control inventory, and to serve as desktop organisers.
only is computing equipment getting smaller, it is getting more sophisticated. Computers are part of many machines and devices
that once required continual human supervision and control. Today, computers in security systems result in safer enviroments,
computers in cars improve energy efficiency, and computers in phones provide features such as call forwarding, call monitoring,
and call answering.
smart machines are designed to take over some the basics task previously performed by people; by so doing, they make life
a little easier and a little more pleasant. Smart cards store vital information such as health records, driver’s license,
bank balances, and so on. Smart phones, cars, and appliances with built in computers can be programmed to better meet individual
smart house has a built-in-monitoring system that can turn lights on and off, open and close windows, operate the oven, and
small computing devices available for performing smart tasks like cooking dinner, programming the VCR, and controlling the
flow of information in an organization, people are able to spend more time doing what they often do best – being creative.
Computers can help people work more creatively.
systems are known for their educational and entertainment value, which we call ‘edutainment’. Multimedia combines
text with sound, video, animation, and graphics, which greatly enhances the interaction between user and machine and can make
information more interesting and appealing to people. Expert systems software enables computers to “think” like
diagnosis experts systems, for example, can help doctors pinpoint a patient’s illness, suggest further tests, and prescribe
enables computers and software that might otherwise be incompatible to communicate and to share resources. Now that computers
are proliferating in many areas and networks are available for people to access data and communications with others, personal
computers are becoming interpersonal PCs. They have the potential ti significantly improve the way we relate to each other.
Many people today teleconmute- that is, use their computers to stay in touch with the office while they are working at home.
With the proper tools, hospital staff can get diagnosis from a medical expert hundreds or thousands of miles away.
the disabled can communicate more effectively with others using computers.
learning and videoconferencing are concepts made possible with the use of an electronic classroom or boardroom accesible to
people in remote locations. Vast databases of information are currently available to users of the internet, all of whom can
sen mail messages to each other. The information superhighway is designed to significantly expand this interactive connectivity
so that people all over the world will have free access to all these resources.
power is critical to ensuring that hardware, software, and connectivity are effectively integrated in a socially responsible
way. People – computers users and computer professionals – are the ones who will decide which hardware, software,
and networks endure and how great an impact they will have on our lives. Ultimately people power must be exercised to ensure
that computers are used not only efficiently but in a socially responsible way.
