Braille display

A Braille display is a device that translates text into Braille characters. Braille displays are used by people who are blind or have low vision to read text. There are different types of Braille displays. Some displays have a small number of Braille cells, while others have a larger number of cells. Some displays can … Read more

Stepper motor

A stepper motor is an electric motor that converts electrical pulses into discrete mechanical movements. The motor’s position can then be controlled very precisely, without any feedback mechanism. Stepper motors are used in a wide variety of applications, including computer peripherals, office equipment, vending machines, and 3D printers. What is stepper motor in simple words? … Read more

Strange matter

In particle physics, strange matter is a hypothetical type of matter that is composed of strange quarks. Strange matter is often discussed in the context of quark matter, which is matter that is composed of any type of quark. Strange matter is of particular interest because it is possible that strange quark matter is the … Read more


The term “ATX” typically refers to the form factor of a motherboard. The ATX form factor is the most common form factor for motherboards. ATX motherboards are typically larger than other form factors, and they usually have more expansion slots. What does ATX location? ATX is a standard for motherboards that was first introduced in … Read more

E-bomb (electromagnetic bomb)

An electromagnetic bomb (E-bomb) is a device that uses a powerful electromagnetic pulse (EMP) to disable electronic equipment. An E-bomb can be used as a weapon to disable enemy computers and other electronic devices, making them useless. E-bombs work by creating a strong electromagnetic field that induces a current in electronic devices. This current can … Read more

Proximity sensing

Proximity sensing is the ability of a device to detect the presence of nearby objects without physical contact. This can be useful for a variety of applications, such as detecting when a user is approaching a device, or for security purposes (e.g. to prevent unauthorized access to a device). Proximity sensing can be implemented using … Read more


Multiprogramming is a technique where multiple programs are run simultaneously on a single processor. This is done by interleaving the execution of the programs, so that each program gets a small amount of time to execute before the next program is run. Multiprogramming is used to increase the utilization of the processor, by keeping it … Read more


Biomechatronics is a field of study that combines engineering with biology to create artificial limbs and other devices that interface with the human body. The term was first coined in the 1970s by Japanese engineer Hiroshi Kobayashi. Biomechatronics devices are designed to restore or enhance the function of a human body part. Examples include artificial … Read more

Electrochemical cell

An electrochemical cell is a device that produces an electric current by converting chemical energy into electrical energy. It consists of two electrodes, one of which is negative and the other positive, and an electrolyte that conducts electrons between the electrodes. The negative electrode is called the cathode and the positive electrode is called the … Read more
