- - - - SCSI can connect internal and external peripheral equipments and devices that conform to the SCSI standard.
      - SCSI cards can be installed on Macintosh and PC platforms.
      - SCSI is preferred for real-time video editing, network servers, and situations that require mirroring.
      - SCSI ID conflicts should be avoided by providing unique IDs to devices.
    - - IDE connections are also known as Advanced Technology Attachment (ATA).
      - They connect only internal peripherals.
      - They can connect four peripherals mounted inside the PC.
      - The circuitry for IDE is less expensive than SCSI.
      - IDE utilizes processor chip time.
    - - It is a standard for connecting devices to the computer using the plug-and-play system.
      - USB uses a single cable to connect 127 USB peripherals to a single PC.
      - It can be attached to one computer at a time.
    - - FireWire was introduced by Apple in the 1980s.
      - It is the industry standard and provides support for high-bandwidth serial data transfer, particularly for digital video and mass storage.
      - Can connect multiple computers and peripheral devices (peer-to-peer).
      - It is the most common method for connecting and interconnecting professional digital video equipment.
  - - - 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).
      - RAM enables the simultaneously running of many applications.
      - ROM is non-volatile. The BIOS program that boots up the computer resides in the ROM.
    - - Floppy disk - Is a inexpensive, removable, and portable device for storing binary data. They are made of flexible mylar plastic coated with a thin layer of special magnetic material.
      - Hard disk - Is a non-removable mass-storage device, and has a higher data storage capacity and data transfer speed.
      - Syquest cartridge - Is a removable storage medium and can hold 44 MB of data.
      - Zip cartridge - Is inexpensive and can hold 100MB of data.
      - Jaz cartridge - Is a removable storage medium that can hold 1GB of data.
      - Magneto-optical drive - Is rewriteable and uses a high power laser. It is suitable for archiving data.
      - Digital Versatile Disc (DVD) - is an optical disc technology for distributing multimedia and feature length movies.
      - CD Recordable (CD-R) - Is very inexpensive, and suitable for short-run distribution of finished multimedia projects. These write-once CDs can be used as high-capacity file archives.
- - - - They include sound chips and microphones.
      - Amplifiers are required when the project has to be presented to a large audience or in a noisy setting.
      - Speakers can be internal or external.
    - - Video creates the maximum visual impact.
      - Video devices include videodisc players and video cards.
      - Videodisc players provide precise control over the image being viewed.
      - Video cards enable the user to place an image in a window on the computer monitor.
    - - Projectors are used when you have a larger audience that can be accommodated around a computer monitor.
      - The different types of projectors include cathode-ray tube (CRT), liquid-crystal display (LCD) panels, stand-alone LCD projectors, and light-valve
      - CRT projectors are compatible with the output of most computers as well as televisions.
      - LCD panels are portable devices that are popular for on-the-road presentations.
      - Light-valve projectors use liquid crystal technology. The images generated are very bright and color saturated and can be projected onto wide screens.
    - - The two types of printers are laser and inkjet.
      - Laser printers offer higher print quality, lower operating costs, but a higher initial cost.
      - Inkjet printers are comparatively cheaper, but require higher maintenance.
      - Color printers have become an important part of multimedia development.
  - - - ISDN stands for Integrated Services Digital Network.
      - It is used for higher transmission speeds by telephone.
      - They transfer data at the rate of 128 Kbps.
      - ISDN lines are used for networking, Internet access, and audio-video conferencing.
      - They are more expensive than the conventional analog lines.
    - - Modems modulate and de-modulate analog signals.
      - They provide connectivity through standard phone lines.
      - Modems can be internal or external.
      - Modem speed is measured in baud, and the standard modem speed should be at least 56 Kbps.
    - - They provide Internet access at speeds faster than a telephone modem, over the same cable network that supplies the television signal.
      - However, due to noise in the system, sending rates may be much slower than receiving rates.
