High-Level Data Link Control (HDLC) HDLC (High-level Data Link Control) is a group of protocols or rules for transmitting data between network points, sometimes referred to as nodes. In HDLC, data is organized into a unit called frame and sent across a network to a destination that verifies its successful arrival. The HDLC frames consist … Read more

What Is Hot Working? Hot working process metals are plastically deformed above their re-crystallization temperature. Being above the re-crystallization temperature allows the material to re-crystallize during formation. This is important because re-crystallization keeps the materials from strain hardening which ultimately keeps the yield strength and hardness low and ductility high.  The ultimate goal of metal … Read more

What Is Static SQL? Static SQL are statements in an application that do not change at runtime (when source code is written) and therefore can be hard-coded into the application.  Static SQL is referred to as static because the SQL statements in the program do not change each time the program is run.
