Amwoga KhalwaleHigh-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 DOC? DOC is a filename extension for word processing documents, most commonly in the proprietary Microsoft Word Binary File Format. The DOC format has been used since the first release of Microsoft word for MS-DOS until 2003 version of word. In DOC, the document is stored in a binary file that also contains … Read more
What Is Silicon Controlled Rectifier (SCR)? A silicon Controlled Rectifier is a 3 terminal and 4 layer semiconductor current controlling device. It is mainly used in the devices for the control of high power. Silicon Controlled Rectifier is also referred to as SCR diode, 4-layer diode, 4-layer device or Thyristor. It is made up of … 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. Static SQL … Read more
Numerical Control (NC) Machine Numerical control, commonly referred to as NC, is a machine which is controlled by the set of instructions in the form of numbers, letters and symbols. In this case, the set of instruction is referred to as program. NC is essential to the operation of modern industrial robots. The two basic … Read more
Portland cement is the most common type of cement widely used around the world as a basic ingredient of concrete, mortar, stucco and non-specialty grout. It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin and usually originates from limestone. Raw materials for the manufacture of … Read more
Paramagnetism Paramagnetism is a form of magnetism whereby some materials are weakly attracted by an externally applied magnetic field and form internal induced magnetic fields in the direction of the applied magnetic field. Materials or substances that display Paramagnetism are referred to as paramagnetic. Some compounds and most chemical elements are paramagnetic under certain circumstances. … Read more
In the motors or generators, both the parts like rotor and stator play a key role. The main disparity between them is that the stator is an inactive part of the motor whereas the rotor is the rotator part. What Is A Stator? The stator is the stationary component of electromagnetic circuits. In different configurations, … Read more
What Is Uninterruptible Power Supply (UPS)? An Uninterruptible Power Supply (UPS) is a component that allows an electronic device to keep running for at least a short time when the primary power source is lost. UPS devices also provide protection from power surges. A UPS contains a battery that ‘’kicks in’’ when the device senses … Read more
