What Is PIPE? A pipe is a mechanism for inter-process communication; data written to the pipe by one process can be read by another process. The data is handled in a first-in, first-out (FIFO) order. The pipe has no name; it is created for one use and both ends must be inherited from the single … Read more

AWT (Abstract Window Toolkit) Abstract Window Toolkit (AWT) is a set of application program interfaces (APIs) used by Java programmers to create graphical user interface (GUI) objects such as buttons, scroll bars and windows. Java AWT components are platform-dependent i.e components are displayed according to the view of the operating system. AWT is part of … Read more

What Is A Jig? Jig is a work holding device that holds supports and locates the workpiece and guides the cutting tool for a specific operation. Often a jig is made of metal which locates and holds the workpiece in a positive manner and also guides the cutting tool such that it is in the … Read more

What Is Power Over Ethernet (PoE)? PoE (Power Over Ethernet) is the name of a number of standard or adhoc systems which passes electric power along with data on twisted pair Ethernet cabling (UTP/FTP cables).  This allows a single cable to provide both data connection and electric power to devices. This is why it is … Read more

What Are Active Instruments? Active instruments are the instruments in which the quantity to be measured activates the magnitude of external power input source that produces the measurement.  An example of an active instrument is a float-type petrol-tank level indicator. In this instrument, the change in petrol level moves a potentiometer arm and the output … Read more

What Is A Router? A router is a networking device that forwards data packets between computer networks.

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.
