6. How does batch processing differ from on-line processing?
7. What is the function of a computer facility within an organization? Describe
briefly three different methods of organizing a computer facility.
5. Discussion:
Determine how the computer facility at your school, work, or other
business is organized. Who decided how to organize it? Does it meet the
needs of the users? How does it use batch and/or on-line processing? Are
there differing opinions relating to the effectiveness of the facility? Why?
Why not? Conduct a minimum of two informal interviews.
6. Essays:
Interview a systems analyst — a computer professional who specializes
in setting up computer-based information systems — or a student
specializing in systems analysis and design. Find out the many ways in
which users' needs and ability to communicate affect the computer
system they apply. Report your findings in an essay.
UNIT 3
Input Hardware
Input hardware can be broken down into two main categories: keyboard-based and
direct-entry. The keyboard, which comes in many shapes and sizes, is probably the
most widely used mechanism for entering data into a computer-usable form. Many
of its keys resemble typewriter keys; however, it also has special-function keys
and special-purpose keys (to issue commands, among other things), cursor-
movement keys, and numeric keys (to enter numbers).
Terminals are often used for data input. They usually consist of a keyboard, video
display screen, and a communications link to a main computer. Terminals can be
dumb, smart, or intelligent. A dumb terminal is used only to input data; it cannot
do any processing on its own. A smart computer is used to input data, but it also
has some limited processing capabilities. An intelligent computer can input and
receive data as well as do its own processing. Common types of terminals are the
