1.4.2. *Windows vs. Macintosh  -The Microsoft Windows operating system can run on assemblages of hardware from countless manufacturers. -Unlike Microsoft, primarily a software company, Apple is a hardware manufacturing  company that  developed  its  own  proprietary  software to run the hardware. -Apple Computer produces both the computer and the operating system. -Many developers believe that multimedia project development is  smoother  and  easier on  the  Macintosh  than  in Windows

1.4.3. *Connections -Integrated Drive Electronics (IDE) -Universal Serial Bus (USB) -FireWire (IEEE 1394)

1.4.4. *IDE  -is a standard interface for connecting a motherboard to storage devices such as hard drives and CD-ROM/DVD drives.

1.4.5. *Memory and storage devices  -Sufficient memory must be allocated for storing and archiving files. -Memory requirements of a multimedia project depend on the project’s content and scope. -The two types of memory are random access memory (RAM) and read-only memory (ROM).

1.4.5.1. RAM-Volatile storage enables the simultaneous running of many applications. Storage that allows to read and write data as many time as needed

1.4.5.2. ROM-is nonvolatile storage. The BIOS program that boots up the computer resides in the ROM.

1.4.5.3. Hard disks nonvolatile storage Is rewriteable permanent memory. have a high data storage capacity and data transfer speed.

1.4.6. *Input devices -An optical character recognition (OCR) device is used to convert printed matter into ASCII text files. -Barcode reader recognize the numeric characters of the Universal Product Code (UPC) -Voice recognition systems recognize spoken words and commands. -Microphones -Digital cameras

1.4.7. *Output devices -Stereo -Monitor -Projector -Printer

1.5. d.Software

1.5.1. Text editing and word processing tools  -Word processors such as Microsoft Word and WordPerfect are powerful applications that include spell checkers, table formatters, and prebuilt templates for letters, resumes, purchase orders, and other common documents. -OpenOffice is a free, downloadable  word processing program.

1.5.2. OCR software  -Makes use of probability and expert system algorithms -Converts bitmapped characters into electronically recognizable text -Is very accurate and saves time and effort

1.5.3. Painting tools allow you to create and modify bitmap images.  -Photoshop, Fireworks, and Painter are examples.

1.5.4. Drawing tools allow you to create and modify vector graphics.  -CorelDraw, Illustrator, and Canvas are examples. -Vector graphics are used by Adobe Flash to reduce download time and scaling problems with web graphics.

1.5.5. Painting and drawing software features include:  -An intuitive graphical user interface -Scalable dimensions -Multiple undo capability -Scalable text font support -Support for third-party special effect plug-ins -Layering capability                                            -Painting features such as smoothing coarse-edged objects into the background with anti-aliasing

1.5.6. 3-D modeling tools allow rendering of objects in a three-dimensional perspective.  -VectorWorks, AutoDesk Maya, and Strata 3D are examples. -3-D graphics usually take a long time to render, so plan accordingly.                                              3-D modeling tools allow rendering of objects in a three-dimensional perspective

1.5.7. Image editing tools  -Powerful tools for enhancing retouching, blurring, sharpening, lightening existing bitmapped images. -Many painting and drawing programs also serve  as image editors. Support third party plug-in.

1.5.8. Sound editing tools  -Cut, copy, paste, and edit certain segments of the music -Enable the user to see music as a waveform as well as hear sound.

1.5.9. Animation, video, and digital movie tools

1.6. e.Authoring system

1.6.1. An authoring tool is a software package which allow developers to :  -Organize and edit the multimedia elements of multimedia project.  -Design screen layouts(interface) using templates -Create interactivity -assembling diverse multimedia elements into a single, cohesive product

1.6.2. Types of authoring tools

1.6.2.1. 1.Card- and page-based authoring tools -Elements are arranged like pages of a book or cards in a stack. -These tools contain media objects such as buttons, text fields, and graphic objects. -It is easy to move from page to page because most programs use buttons and hot spots which allow the user to choose their own path. -LiveCode is an example of a card-based system.

1.6.2.2. 2.Time-based authoring tools -The elements of the program are organized along a time line. -Best suited for messages with a beginning and an end. -Developer can coordinate the time, speed and display length of each elements. -Adobe Flash and Adobe Director are time-based development environments.

1.6.2.3. 3.Icon- and object-based authoring tools    -Icon-based and object-based tools provide a visual programming approach to organizing and presenting multimedia application. -Multimedia elements and interaction cues are organized as objects in a flow chart. -Flow charts can be built by dragging appropriate icons from a library and then adding the content

1.6.3. Objects -Authoring tools generally treat multimedia elements as objects. -Each object is assigned properties or modifiers. -Objects may contain scripts that specify a related action.

1.6.4. You must be prepared to choose the tool that best fits the job. Choosing an authoring tool:

1.6.4.1. 1,Editing and organizing features  -Authoring systems include editing tools to create, edit, and convert multimedia elements such as animation and video clips. -The organization, design, and production process for multimedia involves storyboarding and flow charting. -Visual flow charting or an overview facility illustrates project structure at a macro level.

1.6.4.2. 2,Programming features  -Visual programming with icons or objects is the simplest and easiest authoring process. -Authoring tools offer “very high level language” (VHLL) or interpreted scripting environment.   -for navigation control and for enabling user inputs. Example: Flash, Livecode, & Toolbook.

1.6.4.3. 3,Interactivity features  -Interactivity gives the end user control over the content and flow of information in a project

1.6.4.4. 4,Performance-tuning  -Achieving synchronization is difficult, authoring system should facilitate precise timing of events.

1.6.4.5. 5,playback features  -These features should enable developers to build part of a project and then test it immediately.

1.6.4.6. 6,Internet-playability features Authoring systems provide a means for converting their output to be delivered within the context of HTML or DHTML.
