1 These are Ingredient-Strength combinations (e.g. Acetaminophen 250 MG). For details, download the source code for building DRUG_STRENGTH.  If you only want to use this table for drug and ingredient concepts that are valid (where the field INVALID_REASON is null), the DRUG_STRENGTH records can be used as such.
DEFINITION of 'Botnet'. A network of internet-connected devices that have been compromised by hackers without the knowledge of the legitimate owners.
A subnetwork, or subnet, is a logical, visible subdivision of an IP network. The practice of dividing a network into two or more networks is called subnetting. Computers that belong to a subnet are addressed with a common, identical, most-significant bit-group in their IP address.This results in the logical division of an IP address into two fields, a network or routing prefix and the rest field or host identifier.The rest field is an identifier for a specific host or network interface.or IPv4, a network is also characterized by its subnet mask, which is the bitmask that when applied by a bitwise AND operation to any IP address in the network, yields the routing prefix. Subnet masks are also expressed in dot-decimal notation like an address.
