Remember that the number of elements in the data structure is nListing (list)The list is implemented by the array, and the allocated memory is a contiguous space. Adjust and modify the list elements to return the length of the list, the time complexity of these operations is O (1). The operation time in the head of the list is relatively high, O (n).For example, in a personal local environment, 100,000 elements were added from the tail and head of the list, respectively, and the former took 10ms

The Plug and Play infrastructure of Jini technology consists primarily of three sets of protocols: Lookup (Lookup), Discovery (Discovery), and join (join). Lookup service is the basic component of distributed Jini system, and it provides the central registration mechanism of service in distributed Jini system. In a jini system, the preferred way for a program to find a service is through a lookup service, and the lookup service is also the basis for p

Windows has been providing robust, platform-wide support for public Key Infrastructure (PKI) since Windows 2000. This version contains the first native certification authority feature, introduces autoenrollment, and provides support for smart card authentication. In Windows XP and Windows Server 2003, these features have been extended to provide more flexible enrollment options through version 2 certificate templates, and to support autoenrollment of

group. File and filegroup examples The following example creates a database on an instance of SQL Server. The database consists of a master data file, a user-defined filegroup, and a log file. The master data file is in the primary filegroup, and the user-defined filegroup contains two secondary data files. The ALTER DATABASE statement designates the user-defined filegroup as the default filegroup. The table is then created by specifying a user-defined filegroup.Example: Use
