- There is a wide range of media used for storing multimedia content:
- Floppy disk – are generally too small and too slow to store any serious multimedia applications
- Hard disk – are more suited to multimedia as they can carry far more data than a floppy disk and have far higher transfer rates.
MEMORY and STORAGE - The increasingly large capacities of hard disks developed for server applications can be usefully adopted for multimedia development:
- CD-ROM – as CD-ROM players become increasingly common they provide an inexpensive means for delivering multimedia applications.
- CD-R whereas CD-ROM production involves a manufacturing process, CD-R enables one-off CD-ROMs to be produced using a PC and CD recorder.
- DVD – this storage device will become increasingly common it has greater capacity than CD-ROM (at 4.7 gigabytes) and can also play full motion video using MPEG2. It is capable of reproducing high-resolution images and high fidelity sound.
CONNECTIONS - SCSI
- The Small Computer System Interface (SCSI) is standard that enables up to seven devices (such as scanners, disk drives CD-ROM players and their peripherals) to be connected to a computer.
- All current Macintoshes have SCSI built in whereas for PCs the interface has to be installed.
- Modern SCSI drivers enable data transfer that is as high as 20 to 40 megabits per second but they can be difficult to set up since the cabling used to sensitive to length and resistance.
CONNECTIONS - MCI
- The Media Control Interface (MCI) is a unified, command driven method for software to talk to related multimedia peripheral devices.
- Any hardware device can be connected to a computer running Window.
- Using appropriate drivers it is possible to control the device using codes or simple command strings.
