25.0 GB. 23.28 GiB. 90. Modern compact discs support a writing speed of 52× and higher, with some modern DVDs supporting speeds of up to 24×. [4] Writing a DVD at 1× ( 1 385 000 bytes per second) [5] is approximately 9 times faster than writing a CD at 1× ( 153 600 bytes per second ). [6] However, the actual speeds depend on the type of ...

Genome size ranges (in base pairs) of various life forms. Genome size is the total amount of DNA contained within one copy of a single complete genome.It is typically measured in terms of mass in picograms (trillionths (10 −12) of a gram, abbreviated pg) or less frequently in daltons, or as the total number of nucleotide base pairs, usually in megabases (millions of base pairs, abbreviated ...
Dots per inch. A close-up of the dots produced by an inkjet printer at draft quality. Actual size is approximately 14 by 14 inch (6 by 6 mm). Individual coloured droplets of ink are visible; this sample is about 150 DPI. Dots per inch ( DPI, or dpi [1]) is a measure of spatial printing, video or image scanner dot density, in particular the ...
A molecular-weight size marker in the form of a 1 kb DNA ladder in the rightmost lane, used in gel electrophoresis. Gel conditions are 1% agarose, 3 volt /cm, and ethidium bromide stain. A molecular-weight size marker, also referred to as a protein ladder, DNA ladder, or RNA ladder, is a set of standards that are used to identify the ...
Conventional memory. In DOS memory management, conventional memory, also called base memory, is the first 640 kilobytes of the memory on IBM PC or compatible systems. It is the read-write memory directly addressable by the processor for use by the operating system and application programs. As memory prices rapidly declined, this design decision ...
Kilobyte. The kilobyte is a multiple of the unit byte for digital information . The International System of Units (SI) defines the prefix kilo as a multiplication factor of 1000 (10 3 ); therefore, one kilobyte is 1000 bytes. [1] The internationally recommended unit symbol for the kilobyte is kB. [1]
