In telecommunications and computing, bitrate (sometimes written bit rate, data rate or as a variable R or fb) is the number of bits that are conveyed or processed per unit of time.

The bit rate is quantified using the bits per second (bit/s or bps) unit, often in conjunction with an SI prefix such as kilo- (kbit/s or kbps), mega- (Mbit/s or Mbps), giga- (Gbit/s or Gbps) or tera- (Tbit/s or Tbps). Note that, unlike many other computer-related units, 1 kbit/s is traditionally defined as 1,000 bit/s, not 1,024 bit/s, etc, also before 1999 when SI prefixes were introduced for units of information in the standard IEC 60027-2.

The formal abbreviation for "bits per second" is "bit/s" (not "bits/s"). In less formal contexts the abbreviations "b/s" or "bps" are often used, though this risks confusion with "bytes per second" ("B/s", "Bps").

A. Right click on the song you want to become 128 bit. Then click Create AAC Version. The song will start to convert. About half a minute later you'll get the song fully converted into 128 bit. To check to see if the song is in 128 bitrate right click on the song and click Get Info. A new window should pop up telling you the information on that song, somewhere in there is the bitrate.

Converting a music file to a conventional 128 bit rate?
Q. How do i convert a music file of a higher bit rate to a conventional 128 bit rate without loosing the quality of the music? Can i do it by winamp or any other music player?
Asked by kim_pharaoh7 - Fri Sep 12 21:31:23 2008 - - 1 Answers - 0 Comments

A. You will lose quality, since 128 is a rather low bitrate. Ogg vorbis has best quality at 128... but not widely supported by programs and devices.

Which is more important in a video card - bit rate or RAM?
Q. Say you've got an 8500 chip on a card with 256 MB RAM and a 64-bit rate. Will the performance improve more by upping to 512 MB RAM or by upping to 128-bit? Also, which would require more additional power?

A. both are but bit rate is more. ram is very useful if ure a gamer who plays at the higher widescreen resolutions ( i.e 1680x1050 or 1920x1200) if ure playing at those settings i suggest u look for a card with higer ram such as 512 mb of GDDR3 and atleast a 128 bit card
