A database connection is a facility in computer science that allows client software to talk to database server software, whether on the same machine or not. A connection is required to send commands and receive answers, usually in the form of a result set. Connections are a key concept in data-centric programming.
DSNs collect additional information needed to connect to a specific data source, versus the DBMS itself. For instance, the same MySQL driver can be used to connect to any MySQL server, but the connection information to connect to a local private server is different from the information needed to connect to an internet-hosted public server. The ...

A port scan or portscan is a process that sends client requests to a range of server port addresses on a host, with the goal of finding an active port; this is not a nefarious process in and of itself. [1] The majority of uses of a port scan are not attacks, but rather simple probes to determine services available on a remote machine.
RFC 1282, in which it was defined, states: "The rlogin facility provides a remote-echoed, locally flow-controlled virtual terminal with proper flushing of output." rlogin communicates with a daemon, rlogind, on the remote host. rlogin is similar to the Telnet command, but is not as customizable and is able to connect only to Unix-like hosts.
DBFNTX implementation has almost the same functionality of DBFCDX and RDDSIX. NETIO and LetoDB [2] provide remote access over TCP protocol. Harbour also offers ODBC support by means of an OOP syntax, and ADO support by means of OLE. MySQL, PostgreSQL, SQLite, Firebird, Oracle are examples of databases which Harbour can connect to.
It can be used to enable computers without built-in PXE capability to boot from the network, or to provide additional features beyond what built-in PXE provides. While standard PXE clients use only TFTP to load parameters and programs from the server, iPXE client software can use additional protocols, including HTTP , iSCSI , ATA over Ethernet ...
