Varchar fields can be of any size up to a limit, which varies by databases: an Oracle 11g database has a limit of 4000 bytes, [1] a MySQL 5.7 database has a limit of 65,535 bytes (for the entire row) [2] and Microsoft SQL Server 2008 has a limit of 8000 bytes (unless varchar(max) is used, which has a maximum storage capacity of 2 gigabytes).
If a sign is stored in its own MAU, then 4 bits will be wasted with byte addressing (50% efficiency), while 28 bits will be wasted with 32-bit word addressing (12.5% efficiency). If a sign is "packed" into a MAU with other data, then it may be relatively more expensive to read and write.
A foreign key is a set of attributes in a table that refers to the primary key of another table, linking these two tables. In the context of relational databases, a foreign key is subject to an inclusion dependency constraint that the tuples consisting of the foreign key attributes in one relation, R, must also exist in some other (not necessarily distinct) relation, S; furthermore that those ...

The AMD Radeon R9 290X (Sapphire OEM version pictured here) uses a 512-bit memory bus.. The Intel Xeon Phi has a vector processing unit with 512-bit vector registers, each one holding sixteen 32-bit elements or eight 64-bit elements, and one instruction can operate on all these values in parallel.
In computing, a word is the natural unit of data used by a particular processor design. ... 50 bit w — — — — 1944 Harvard Mark I: 23 d w — 24 bit — — 1946
The California Job Case was a compartmentalized box for printing in the 19th century, sizes corresponding to the commonality of letters. The frequency of letters in text has been studied for use in cryptanalysis, and frequency analysis in particular, dating back to the Arab mathematician al-Kindi (c. AD 801–873 ), who formally developed the method (the ciphers breakable by this technique go ...
65535 is the sum of 2 0 through 2 15 (2 0 + 2 1 + 2 2 + ... + 2 15) and is therefore a repdigit in base 2 (1111111111111111), in base 4 (33333333), and in base 16 (FFFF).. It is the ninth number whose Euler totient has an aliquot sum that is : (()) =, [2] and the twenty-eighth perfect totient number equal to the sum of its iterated totients.
