9). In the case of K + and Cl - , the electrical and concentration gradients of molecules work against each other. K + is attracted toward the inside of a cell because of the inside-negative membrane potential, but the moleculeâs concentration gradient works in the other direction.
Directory Definition. The term directory is used in a computer software context to refer to what appears to the user to be a container or folder1 that can hold files and other directories. A file is a named collection of related data that appears to the user as a single, contiguous block of information and that is retained in storage.
Operating System Configuration. The Windows directory is the directory that contains Windows-based applications, initialization files, and help files. The GetWindowsDirectory function retrieves the path to this directory. The system directory is the directory that contains dynamic-link libraries, drivers, and font files. The GetSystemDirectory function retrieves the path to this directory. The GetUserName function retrieves the name of the user currently logged onto the system. The user name is either the logon name or the user's full name, if the latter is included in the registry. An environment variable is a symbolic variable that represents some element of the system, such as a path, a file name, or other literal data. For example, the environment variable PATH represents the directories in which to search for executable files.
