  2. Optical storage media writing and reading speed - Wikipedia

    en.wikipedia.org/wiki/Optical_storage_media...

    Disc quality: optical disc recorders detect the available speed options based on the data which is available on the disc itself. However, some low-quality discs make a high-speed option available to the software, while the burning process can never reach that speed in practice. The reading and writing process may not happen at a steady speed.

  3. Data-rate units - Wikipedia

    en.wikipedia.org/wiki/Data-rate_units

    The ISQ symbols for the bit and byte are bit and B, respectively.In the context of data-rate units, one byte consists of 8 bits, and is synonymous with the unit octet.The abbreviation bps is often used to mean bit/s, so that when a 1 Mbps connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s (megabyte per ...

  4. Bit rate - Wikipedia

    en.wikipedia.org/wiki/Bit_rate

    In telecommunications and computing, bit rate (bitrate or as a variable R) is the number of bits that are conveyed or processed per unit of time. [1]The bit rate is expressed in the unit bit per second (symbol: bit/s), often in conjunction with an SI prefix such as kilo (1 kbit/s = 1,000 bit/s), mega (1 Mbit/s = 1,000 kbit/s), giga (1 Gbit/s = 1,000 Mbit/s) or tera (1 Tbit/s = 1,000 Gbit/s).

  5. Digital video - Wikipedia

    en.wikipedia.org/wiki/Digital_video

    By definition, bit rate is a measurement of the rate of information content from the digital video stream. In the case of uncompressed video, bit rate corresponds directly to the quality of the video because bit rate is proportional to every property that affects the video quality. Bit rate is an important property when transmitting video ...

    A dial-up service connects to the internet through a phone line with a maximum speed of 56 kbps. Broadband refers to a connection that transmits a large amount of data at a high speed. A connection having a download speed of 256 kbps or faster is currently classified as broadband. You cannot make and receive phone calls while you are connected ...

  8. Average bitrate - Wikipedia

    en.wikipedia.org/wiki/Average_bitrate

    Average bitrate can also refer to a form of variable bitrate (VBR) encoding in which the encoder will try to reach a target average bitrate or file size while allowing the bitrate to vary between different parts of the audio or video. As it is a form of variable bitrate, this allows more complex portions of the material to use more bits and ...

    en.wikipedia.org/wiki/Video_CD

    Video CD (abbreviated as VCD, and also known as Compact Disc Digital Video) is a home video format and the first format for distributing films on standard 120 mm (4.7 in) optical discs. The format was widely adopted in Southeast Asia , South Asia , East Asia , Central Asia and West Asia , superseding the VHS and Betamax systems in the regions ...
