Virtual Telecommunications Access Method (VTAM) is the IBM subsystem that implements Systems Network Architecture (SNA) for mainframe environments. [1] VTAM provides an application programming interface (API) for communication applications, and controls communication equipment such as adapters and controllers. In modern terminology, VTAM ...
The Corps of Engineers, as it is known today, was established on 16 March 1802, when President Thomas Jefferson signed the Military Peace Establishment Act, whose aim was to "organize and establish a Corps of Engineers ... that the said Corps ... shall be stationed at West Point in the State of New York and shall constitute a military academy."
VTAM, [17] [18] a software package to provide log-in, session keeping, and routing services within the mainframe. A terminal user would log-in via VTAM to a specific application or application environment (e.g. CICS, IMS, DB2, or TSO/ISPF). A VTAM device would then route data from that terminal to the appropriate application or application ...
Guidance, navigation and control (abbreviated GNC, GN&C, or G&C) is a branch of engineering dealing with the design of systems to control the movement of vehicles, especially, automobiles, ships, aircraft, and spacecraft. In many cases these functions can be performed by trained humans.

Command guidance has the advantage of isolating most of the equipment for the missile guidance at the launcher, where size and weight are significantly less important. In these systems, the radar that provides guidance is on the ground or ship and the missile lacks an independent guidance system. Typically two radars are used, one tracking the ...
BTAM was superseded by VTAM for Systems Network Architecture (SNA) devices. BTAM continued to be supported in later iterations of the system architecture, and IBM finally withdrew support in 2000. BTAM requires the application program or transaction processing system to handle almost every detail of the protocol. This is harder than using a ...
