In computer science, a lookup table (LUT) is an array that replaces runtime computation of a mathematical function with a simpler array indexing operation, in a process termed as direct addressing.
Central to the mechanism is that blocks of addresses (also called indirect blocks) are only allocated as needed. For example, a 12-block file would be described using just the inode because its blocks fit into the number of direct pointers available. However, a 13-block file needs an indirect block to contain the thirteenth address.
In some older computer architectures, indirect words supported a variety of more-or-less complicated addressing modes. Another important example is the domain name system which enables names such as en.wikipedia.org to be used in place of network addresses such as 208.80.154.224. The indirection from human-readable names to network addresses ...
Dispatch table a branch table by another name used for late binding; Function pointer arrays of addresses to functions as used in branch tables; Indirect branch; Lookup table an array of items to be matched, sometimes holding pre-calculated results; Switch statement a high level language conditional statement that may generate a branch table
Pivot tables are not created automatically. For example, in Microsoft Excel one must first select the entire data in the original table and then go to the Insert tab and select "Pivot Table" (or "Pivot Chart"). The user then has the option of either inserting the pivot table into an existing sheet or creating a new sheet to house the pivot table.
Such a proof is again a refutation by contradiction. A typical example is the proof of the proposition "there is no smallest positive rational number": assume there is a smallest positive rational number q and derive a contradiction by observing that q / 2 is even smaller than q and still positive.
For example, for some vendors, a HOLAP database will use relational tables to hold the larger quantities of detailed data and use specialized storage for at least some aspects of the smaller quantities of more-aggregate or less-detailed data. HOLAP addresses the shortcomings of MOLAP and ROLAP by combining the capabilities of both approaches ...
For example, the U flag indicates that an IP route is up. filtering criteria: Access-control lists associated with the route; interface: Such as eth0 for the first Ethernet card, eth1 for the second Ethernet card, etc. Shown below is an example of what the table above could look like on a computer connected to the internet via a home router:
