GRAPHICS TOOLS AND
DESKTOP PUBLISHER
There are 2 basic types: Bitmapped, Vector
Bitmapped (or raster): each pixel directly maps, or corresponds to, a portion of the image. The computer must keep track of position and color information for each pixel. #become jagged looking when scaled to larger size
Vector (or draw): the computer “remember” the steps involved in drawing a particular graphic image. This information is independent of a particular screen location or a graphic’s size. #vector can be scaled without any loss of quality.
FEATURES OF GRAPHICS TOOLS
Creative Arts : permit you to produce original artwork or modify existing artwork. There are variety of stimulate tools intended to mimic what an artist use (pencil, paintbrush, color palette, eraser etc.). You can select and control colors, and fill shapes with colors and/or patterns, and let you apply special effects (blurring, textures, and the illusion of embossing).
Packages e.g.: Adobe Photoshop, Adobe illustrator, Corel draw, Painter etc.
Business and scientific graphics : a program accept data, from within the program or from another source (spread sheet – Microsoft excel), and produce a chart or a graph . Business graphics include bar chart, pie chart, line graph etc. Scientific focus on line graphs as well as trigonometric and other mathematical functions.
Packages e.g.: Cricket graph, graphical analysis, Microsoft graph etc.
Mechanical Drawing : computer-aided design (CAD) is used for the production of blueprints and factory floor layouts, for landscape architecture, for the design of machined parts, and so on
Packages e.g.: AutoCAD, PowerCADD, IntelliCAD
Print graphics : inexpensive program that use built-in clip art to produce simple printed work such as signs, banners, and greeting cards etc.
Packages e.g.: PrintMaster, PrintShop
Desktop Publishing : response to demand for control over both text and graphics on a printed page. It gives users a high degree of control over the composition and layout of materials on printed page. Desktop publishing program typically afford greater control and precision. This software remains important today both in the publishing industry and for such educational applications as school newspapers.
Packages e.g.: Adobe PageMaker, QuarkXPress, Ventura Publisher, Publishing center etc.
EXAMPLE USES FOR TEACHER AND STUDENTS
Teacher’s Uses

Producing major school works such as the school newspaper or yearbook
PROBLEMS AND PITFALLS
Student may tend to emphasize from over substance, with page layouts programs, students (and teacher) often spend inordinate time fiddling with how a document looks. They may experiment with different fonts and page layouts at length while worrying little about the content. With graphics tools too, students often spend much time to experimenting with various features,
COMPUTER DATABASES
AND DATABASE
MANAGEMENT
What is Computer Database?
A DATABASE IS A COLLECTION OF INFORMATION. COMPUTER DATABASE IS TO COLLECT THE DATA BY USING THE COMPUTER PROGRAM.
ADVANTAGES OF
COMPUTERIZED
DATABASE
Flexible access
Ease of manipulation
Amount of information
Features of Computer Database Programs
FIELDA single information category such as first name, last name, telephone number, or address
First Name _____________
RECORDAn organized collection of information categories
First Name _______________Last Name _______________Telephone Number_________Address__________________
DATAFILEA collection of commonly structured records
DATABASEA collection of interrelated datafiles
Example Uses of DatabaseTeacher’s uses Student’s uses
• Creating and maintaining basic information about students
• Collecting the test or quiz questions referenced by topic, book chapter, or objective.
• Storing teaching methods, strategies, and lesson plan.
• Investigating the answer to complex questions through searching databases
• Maintaining information of various kinds
• Storing the tasks of each subject
PRESENTATION SOFTWARE
Presentation Software is designed for producing and displaying computer text and images. Popular presentation packages include Microsoft PowerPoint, Adobe Persuasion, Lotus Freelance Graphics, Corel WordPerfect Presentations, and Gold Disc’s Astound.

TEACHERS’ USES
Supporting lectures or other presentation to groups in the classroom.
Making presentations to school boards, at professional meetings, or in other nonschool settings. Recording the results of brainstorming or other development activities in class.
Displaying information at events, most presentation packages support timed or auto-run features that allow slide shows to run unattended.
Preparing notes, pictures, or other material that can be printed, transferred to photographic slides, or converted for placement on the Web. a
STUDENTS’ USES
Making in- class presentations or reports and preparing textual information, pictures, or other material that can be printed, transferred to photographic slides, or converted for placement on the Web.
PROBLEMS AND PITFALLS
Students may emphasize form over substance. When use prepared templates, can make almost any content look good. First, construct presentations using a blank template or in outline mode to discourage them from focusing on the flashy elements of the package. After creating the content, students then can focus on adding visual appeal. Caution students to avoid overdoing available effects when adding visual elements. Good design principles still apply. Teacher who presentation software, sometimes fall into the trap of wanting to turn everything into a presentation. It is best to take a variety of approaches when trying to reach different learners and help them stay actively involved.

FEATURES OF COMPUTER TELECOMMUNICATIONS
Electronic Mail (e-mail) is the most widespread application of computer telecommunications. It is analogous to postal mail but much faster and more versatile. E-mail allows private messages to be sent and received from individuals to other individuals or from individuals to groups.
INFORMATION RETRIEVAL
Information Retrieval is one of the most important uses of internet. A source of vast information resource on the Internet is the World Wide Web (WWW or just the Web.) The Web consists of millions of sites of information displayed in hypermedia format.
INFORMATION PUBLISHING
Information Publishing is being seen as a place where organizations and individuals can display information for others to view and/or retrieve. So, many schools have created their own Websites, which teachers, students, and whole classes often use for display of project as well as for dissemination of information about the school.
