                        Unit 4 Today's Offices

Today's organizations have a variety ofoffice automation hardware and software components at their disposal. The listincludes the telephone and computer systems, electronic mail, word processing,desktop publishing, database management system, two-way cable TV,office-to-office satellite broadcasting, on-line database service, and voicerecognition and synthesis. Each of these components is intended to automate atask or function that is presently performed manually. Experts agree that thegoal can be accomplished when the computer, communication, and office equipmentare networked and an office work can easily access the entire system through apersonal computer sitting on his or her desk. Then it will be possible tochange substantially the way people work in an office.

What PowerPoint Creates

On-screen Presentations

Slides are the images of your presentation.Slides can have titles, text, charts, drawn objects and shapes, as well as clipart, movies, sounds, and visuals you create in other applications.

As you create slides, use the slide master todesign how your presentation will look and to give it a format that carriesthrough from beginning to end.

35mm slides

A service bureau can transform yourelectronic slides into 35mm slides.To have slides made by Genigraphics, use the Genigraphics Wizard and follow theinstructions onscreen. Or follow the instructions provided by your servicebureau.

To design slides that are the correct heightand width for 35mm-slideoutput, click Slide Setup on the file menu.

Word Processing Software

Word Processing Software such as WORD, WPSetc. is widely used in the office environment to prepare letters and memos. Itallows the user to enter data on a keyboard. As the word and letters areentered, they are displayed in the CRT screen and stored in main memory of thepersonal computer. If necessary, key errors may be corrected; words, sentences,paragraphs, or pages may be added or deleted; margins can be established; pagelength can be defined; and many other functions that involve the manipulationof the written word can be performed.

After the text material has been created onthe personal computer CRT screen, it can be printed or stored in the auxiliarystorage for the future reference. The personal computer as a word processor israpidly replacing the typewriter and the dedicated word processor in manyoffices.
