Bit rate
Bit rate is the data stream during playback of audio or video data. It is given in
kilobyte per second (kbit/s or kbps) and also determined the file size. An MP3
file that is 3 minutes long and has a constant bit rate of 128 kbit/s is ca. 2.8
MB in size.
Blue screen
The blue screen is a critical Windows error message. It is issued only when
significant errors for the computer's function are found in the core, drivers or
hardware. Because the errors are not caused by programs, which may be
simply shut down, the computer has to be restarted.
Blu-ray
Since early 2008, Blu-ray discs are viewed as successors to DVDs and offer
especially high storage capacity of up to 27 GB in a single layer (double-layer
up to 54 GB) with very few write errors. The high storage capacity of the
Blu-ray disc suits high definition videos and slideshows in high quality perfectly,
since these are characterized by large file sizes (depending on material
approximately 40 MB/sec) and very high memory use.
The term Blu-ray Disc comes from the blue color of the laser. Because a color
cannot be registered as a trademark, the letter "e" was removed from the word
"blue".
boot-capable
Storage devices are boot-capable if they feature a sector that helps load an
operating system.
