What is a Hard Disk Drive (HDD)?31 May 2021
Hard Disk Drive (HDD) is the main storage device of a computer. It consists of one or more aluminum or glass discs. These discs are covered with ferromagnetic material. The vast majority of hard drives are fixed hard drives, which are permanently sealed and fixed in the hard drive. With the development of hard disk drives, removable hard disk drives have also appeared, and they are becoming more and more popular.
Graphics Card Explained: Classification, Working and Structure27 May 2021
A Graphics card (Video card, Display card, Video adapter) is one of the basic components of personal computers. It converts the display information required by the computer system to drive the display, which is an important component that connects the monitor and the PC motherboard, and is one of the important equipment of "human-machine". Its built-in parallel computing capability is also used for deep learning and other operations.
Wireless Charging Explained: Working and Standards26 May 2021
Wireless charging technology originates from wireless power transmission technology, which can be divided into low-power wireless charging and high-power wireless charging. Low-power wireless charging often uses electromagnetic induction, such as the Qi method for charging mobile phones. High-power wireless charging often uses resonance (most electric vehicle charging uses this method) from the power supply equipment (charger) to transfer energy to the device that uses electricity.
What is a USB Flash Drive?25 May 2021
USB Flash Drive integrates disk storage technology, flash memory technology, and universal serial bus technology. The USB port is connected to the computer, which is the channel for data input/output. The master chip makes the computer identify the USB flash drive as a movable disk, which is the "brain" of the USB flash drive. The flash memory saves data. The PCB bottom plate connects the components together and provides a platform for data processing.
Near Field Communication (NFC) Explained: Working and Applications24 May 2021
Near Field Communication (NFC) is evolved from the integration of non-contact radio frequency identification (RFID) and interconnection technology. Devices using NFC technology can exchange data when they are close to each other. By integrating the functions of inductive card readers, inductive cards, and point-to-point communication on a single chip, applications such as mobile payment, e-ticketing, access control, mobile identification, and anti-counterfeiting can be realized by using mobile terminals.
Solid-state Drive (SSD): Classification and Architecture22 May 2021
A solid-state drive (SSD) is a hard drive made of solid-state electronic memory chip arrays. SSD is composed of a control unit and storage unit (FLASH chip, DRAM chip). Solid-state drives are widely used in many fields such as military, vehicle, industrial control, video surveillance, network monitoring, network terminals, electric power, medical treatment, aviation, navigation equipment, and so on.
Optical Image Stabilization (OIS) Explained: Types and Working21 May 2021
In cameras or other imaging instruments, optical image stabilization (OIS) refers to the setting of optical components to avoid or reduce instrument jitter in the process of capturing optical signals, thereby improving image quality.
What is AMOLED?25 April 2021
AMOLED is an active-matrix organic light-emitting diode. AMOLED is a display technology for mobile devices, digital cameras, media players, and television. It uses active matrices to address pixels and uses a special type of film technology, wherein the organic compound forms an electroluminescent material.
What is a DC-to-DC Converter?23 April 2021
DC-DC converter, also known as a DC-to-DC converter or DC transformer, is a circuit or electromechanical device that converts electrical energy. It can convert a direct current (DC) power source into a direct current power source (or approximate DC) of different voltages. Its power range is from very low (small batteries) to very high (high-voltage power transmission). The output voltage of some DC-DC converters has the same reference point as the input voltage, while the output voltage of some DC-DC converters is isolated from the input voltage.
What is a Printed Circuit Board?22 April 2021
A printed circuit board(PCB) is the provider of electrical connections for electronic components. Printed circuit boards are often represented by "PCB", but cannot be called "PCB boards".
RF Modulator: Working Principle and Development Trend21 April 2021
An RF modulator is an electronic device that provides a baseband signal, which is used to convert radio frequency resources.There are many RF modulators available, but all functions work in a similar way.
What is an Accelerometer Sensor?20 April 2021
An accelerometer sensor is a sensor that can measure acceleration. It is usually composed of masses, dampers, elastic components, sensitive components, and adaptive circuits. In the process of acceleration, the sensor obtains the acceleration value by using Newton's second law, measuring the inertial force on the mass block. According to the different sensitive components of the sensor, common accelerometer sensors include capacitive, inductive, strain gauge, piezoresistive, piezoelectric and so on.
