In computer software, specifically the DCL command-line interface of the OpenVMS operating system, the DIRECTORY command (often abbreviated as DIR) is used to list the files inside a directory. [1] It is analogous to the DOS dir and Unix ls commands.
In computing, dir (directory) is a command in various computer operating systems used for computer file and directory listing. [1] It is one of the basic commands to help navigate the file system . The command is usually implemented as an internal command in the command-line interpreter ( shell ).
Said byte is followed by any number of additional bytes in this range, and then a byte in the range 0x30-0x7E. These escape sequences are further subcategorised by the low two bits of the first byte, e.g. "type 2F " for sequences where the first byte is 0x22 ; and by whether the final byte is in the range 0x30—0x3F indicating private use (e.g ...
Therefore, a relation can have multiple candidate keys, each with a different number of attributes. [2] Specific candidate keys are sometimes called primary keys, secondary keys or alternate keys. The columns in a candidate key are called prime attributes, [3] and a column that does not occur in any candidate key is called a non-prime attribute.
Overdrawn at the Memory Bank is a 1984 science-fiction television film starring Raul Julia and Linda Griffiths (pictured).Based on a 1976 short story by John Varley from the Eight Worlds series, the film takes place in a dystopian future where an employee at a conglomerate, played by Julia, gets trapped inside the company's computer, where he is monitored and later abetted by a character ...
In cryptography, key size or key length refers to the number of bits in a key used by a cryptographic algorithm (such as a cipher).. Key length defines the upper-bound on an algorithm's security (i.e. a logarithmic measure of the fastest known attack against an algorithm), because the security of all algorithms can be violated by brute-force attacks.
MySQL Cluster, also known as MySQL Ndb Cluster is a technology providing shared-nothing clustering and auto-sharding for the MySQL database management system. It is designed to provide high availability and high throughput with low latency, while allowing for near linear scalability. [ 3 ]
Bucket sort can be seen as a generalization of counting sort; in fact, if each bucket has size 1 then bucket sort degenerates to counting sort. The variable bucket size of bucket sort allows it to use O(n) memory instead of O(M) memory, where M is the number of distinct values; in exchange, it gives up counting sort's O(n + M) worst-case behavior.
