COMPUTERS MAKE THE WORLD SMALLER AND SMARTER
A People - computer 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.
B 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.
C The information superhighway is designed to significantly expand this
interactive connectivity so that so people all over the world will have free access
to all these resources.
D Connectivity enables computers and software that might otherwise be
incompatible to communicate and to share resources.
E Each of these people (and thousands more like them) has a vital interest in
what computers can (or cannot) do, they also need to know when the various rich
promises in the technology will be realized in usable programs and devices.
F A smart house has a built-in monitoring system that can turn lights on and off,
open and close windows, operate the oven, and more.
G Not 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 environments, computers in cars improve energy efficiency, and
computers in phones provide features such as call forwarding, call monitoring,
and call answering.
These smart machines are designed to take over some of the basic tasks
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,
drivers’ licenses, bank balances, and so on. Smart phones, cars, and appliances
with built in computers can be programmed to better meet individual needs.
With 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.
The 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 handheld computing
devices to collect data at a customer site, to generate forms, to control inventory,
and to serve as desktop organisers.
