Reality Distortion Field (RDF)

Definition

A reality distortion field (RDF) is a phenomenon in which an individual’s intellectual abilities, persuasion skills and persistence make other people believe in the possibility of achieving very difficult tasks. The term was coined by Apple employee Bud Tribble to describe former Apple Inc. co-founder, CEO and chairman Steve Jobs' ability to encourage his team to complete virtually any assigned or delegated task.

Techopedia explains:

There are two sides to the reality distortion field. The positive is that it demonstrates how Steve Jobs bent reality in such a way that a difficult or impossible task was made to appear possible, or even easy. The primary objective of this technique was to inspire employees and motivate them to tackle challenging situations in pursuit of an objective or goal. Although all good managers aim to inspire their teams in some regard, RDF implies Jobs' legendary charisma, which many believe helped Apple achieve results that otherwise would not have been possible. In this way, his distortion field was a huge leadership attribute.

 

Delay Distortion

Definition :

Delay distortion is a guided transmission media phenomenon where network data signals are transmitted via a medium at a certain frequency and speed. 
Delay distortion occurs when signal velocity and frequency vary. This means that all signals do not arrive at the same time, resulting in distortion of the signal. This term is commonly used in fiber optics.

Techopedia explains:

Distortion refers to the change or alteration of an object. Data signals must be transmitted over a medium with a defined frequency and speed. Digital data are highly vulnerable to delay distortion. This is because any transmitted data packet bit can spill and destabilize the overall packet transmission pattern.  Delay distortion may be resolved with different techniques. The best example is a telephone line, which equalizes speed signals with medium frequency.

 

Delay-Locked Loop (DLL)

Definition

A delay-locked loop (DLL) is a digital circuit that provides high-bandwidth data transmission rates between devices. DLL transmissions have no propagation delay, low clock skew between output clock signals and advanced clock domain control. DLL is similar to a phase-locked loop except that it does not include an internal voltage-controlled oscillator.

Techopedia explains 

A delay locked loop is a circuit that's fed by a reference clock. A DLL tries to determine the period of that reference clock by adjusting a feedback look via the delay in a variable delay buffer. When the delayed clock signal matches the incoming clock signal, the loop is considered locked.

 

Circuit

Definition

In the most fundamental sense, the term circuit refers to a physical or conceptual loop, often with an emphasis on resolving or closing that loop to accommodate various operations associated with electrical systems or other technologies. In IT, the term is often used when discussing the physical manufacturing of devices or pieces of hardware.

Techopedia explains 

Over time, the physical concept of an electrical circuit has developed along with various other advancements in electronics. For example, a newer type of circuit board called a printed circuit board (PCB) allows for more efficient types of mass production for hardware. These types of boards are also sometimes called etched boards because of the fine manipulation of copper or conductive materials to create core functionality.

Innovations like PCBs have enabled smaller devices through strategies like layering circuitry on a board, or using lasers to drill very small holes in a PCB design. This technology has complemented the manufacturing of ever smaller processors, and has made it possible for advanced electronic functionality to be put into hardware pieces as small as a standard identification card, or a very small portable computing device such as the Raspberry Pi, a newer example of a low-cost, small-scale consumer device. These new advances have changed the manufacturing and engineering of circuits in fundamental ways, which is a major part of both electrical and data hardware design.
