The two most common categories in which USB cables are classified are USB A and USB C. The primary distinction between USB A and USB C is based on the nature of the two cables in relation to their plug-in orientation. In general USB A does not support reversibility in terms of plug-in orientation within the port, whereas USB C supports reversibility and can be plugged in either way regardless of port orientation.
USB A is the most commonly used type of connector in general, and it has a rectangular shape. It is also known as the most traditional type of USB. It is also known as standard A. This cabling port is commonly found in computer-like devices such as smart televisions, gaming consoles, DVD players, and so on.
USB C is the most recent type of USB cable in use. It has a square shape. The plug-in reversibility that it provides is the reason for enormous popularity. It is a high-power cable that can handle high-speed data transfer.

A VIR is a wire that is primarily made of a tinned conductor with a rubber coating. Tinning the conductor prevents the rubber from adhering to it. The thickness of the rubber is primarily determined by the operating voltage for which the wire is designed. To protect the conductor from moisture, cotton branding is applied over the rubber insultations. So, the wire is waxed to ensure cleanliness.

Answer:
The AIC rating specifies the maximum available fault current that an overcurrent protection device will safely clear when a fault is applied to the overcurrent protection device's load side. The AIC rating is only applicable to overcurrent protection devices. It is irrelevant to standard relay, and standard relays do not have an AIC rating.
POE stand is a wired ethernet local area network implementation technology that allows the electrical current required to operate each device to be carried by ethernet data cables rather than standard electrical power cords and wiring.
PoE which is used in both smart home applications and business premises uses less expensive Ethernet cabling that can transport both power and data instead of electrical wiring, which only supplies power and requires separate wiring for data. PoE transport both power and data over cable, less wiring is required and existing electrical wiring can be reused.
PoE was created in 2003 to support devices such as wireless access points. Individual vendors previously used various forms of proprietary PoE to provide PoE capabilities. Some of these proprietary PoE devices are still in use. PoE installer must locate these older, proprietary devices because they can be troublesome or incompatible with later released standard PoE devices. Today's standard PoE devices make AP installations simpler and more adaptable in ceilings that can wire for electrical power.
Power over Ethernet provide numerous benefits to an installation:

UV is a type of non-ionizing radiation emitted by the sun and other artificial sources such as tanning beds. While it has some benefits for people, such as the production of vitamin D, it can also pose health risks. The sun is our natural source of UV radiation.
Answer:
A DVR is a device that records video to a local storage device, most commonly a hard drive. DVR can record video to a local storage device, most commonly a hard drive. DVR can record on-site analogue video sources or capture video from a digital source. DVRs can be remotely accessed by connecting to an analogue camera via coaxial cables. DVR has more features such as the ability to search for events or sort by time and date.

PQEP is a IC package with leads extending from all four sides of the package body, PQFP are mostly square, but there are some rectangular variants. The PQFP is one of the several quad flat pack package type.
Answer:
PPGA is a square-shaped plastic package with pins or leads arranged in a square array at the package bottom. The PPGA is just one of the several PGA package types. A PGA package can provide much higher lead counts than other packages due to the array arrangement of the leads. This is why the PGA is a popular choice for devices with a high number of I/Os such as a microprocessor.
