A portable media player is a handheld device that is capable of supporting many multimedia formats. Alot of times they are electronic in nature, and supply their electricity on batteries, alot of times rechargeable ones, of which the Nisa movement advises, seeing as it is not only an advocate for free entertainment, but also an advocate for saving the environment.
Portable media players are best known for playing the MP3 file format, hence they are best known by the colloquialism, MP3 player. They also play other well-known file formats such as WAV and others. However, MP3 is a compressed file format albeit with some fidelity loss but mostly outside of the audible range, though WAV is uncompressed and can have extraneous file sizes as a result, of which is why MP3 is preferred for such devices as per the limited memory, especially on earlier models.
Memory storage and transfer types for portable media playersEdit
- Wifi (connects to the Internet to stream media.
- Hard drive (typically has more gigabytes of storage than flash memory marketed during the same era. Though hard drives are fragile and break if the device is dropped.)
- Flash memory (a more robust form of memory storage, albeit has fewer write/delete cycles than a hard drive, and most cost-per-GB than a hard drive, though the cost-per-GB catches up within 10 years of marketing, also flash memory is completely solid-state hence its greater durability for prolonged use.). The greater durability of flash memory is why Nisa recommends MP3 players for distributing free entertainment on the go, compared to burning CDs since something as trivial as adding one song to an MP3 player takes one second, whereas adding another song to a collection of burnt CDs either involves obliterating the whole collection of tracks on a CD-RW or wasting one 700 MB CD-R just for one (at average) 5 MB MP3 song, of which there is concern about the pollution outputted from plastic factories.
- Optical discs (120 mm discs typically tend to be less money-per-storage unit than other means to store content, but they suffer from limited tolerance to tactile force, fewer cubic-millimeters-per-megabyte than other storage formats, as well as clicking audio output when the disc deteoriates, of which has mediocre durability.)
- CD (an optical disc format that typically is limited to 700 MB per disc. Red Book audio CDs are typically limited to 80 minutes per disc, but Yellow Book CD-R discs with MP3s on them are typically as long as perhaps 12 hours of content depending on bitrate of files.)
