LCD (Liquid Crystal Display)  is a flat panel display,  electronic visual display,

or video display that uses the light modulating properties of liquid crystals (LCs).

Produces better quality, sharp and crisp images. Adv:

LCD monitors are smaller, thinner and weigh half as much as CRTs.

LCD monitors don't produce the flicker that CRTs do, generating less eye strain.

LCD monitors use low electrical power consumption  more energy efficient and offer safer disposal

LED (light-emitting diode Display)   flat panel display that

uses LED backlighting instead of the cold cathode (CCFL) backlighting used in most other LCDs. The use of LED backlighting allows for:

thinner panel, lower power consumption, better heat dissipation, brighter display, better contrast levels.

Storage Devices storage device is a hardware device capable of

storing information. There are two storage devices used in computers; Primary storage (or main memory or internal

memory), often referred to simply as memory, is the only one directly accessible to the CPU. Eg: RAM

Secondary storage (also known as external memory or auxiliary storage), differs from primary storage in that it is not directly accessible by the CPU. Secondary storage does not lose the data when the device is powered down eg: hard disk, floppy disk, CD, USB drive ect..

Types of storages Magnetic storage: uses patterns of magnetization on

a magnetically coated surface to store information.

Optical storage:  store data optically -- using laser beams. Read-Only Discs: CD-ROM and DVD-ROM Discs  Recordable Discs: CD-R, DVD-R, and DVD+R Discs  Rewritable Discs: CD-RW, DVD-RW, DVD_RW, DVD-RAM,

and Blue Laser Discs

Types of storages Flash Storage: consists of flash memory with an

integrated Universal Serial Bus (USB) interface. USB flash drives are typically removable and rewritable. Use in digital camera, pendrive, handheld PCs etc..

smart card :  A credit-card-sized piece of plastic that contains some computer circuitry, typically a processor, memory, and storage. it can be used to hold specific pieces of information that may need to be updated periodically.

Playback system is a computer components that allows us to playback the created integrative media.

The systems need to support the application for smooth playback.

Things need to consider : Speed of microprocessor (in MHZ or GHz) Memory Storage Display Devices (LCD vs LED) Video and audio card capabilities CD and DVD speed

Development system is a computer components needed for creation /production of the media integrative.

The tedious process of media integrative development, needs higher end system specification.
