    Introduction to Nondestructive Testing

    Nondestructive testing (NDT) is the process of inspecting, testing, or evaluating materials, components, or physical systems for unexpected irregularities, without destroying the serviceability of the part or system. In other words, when the inspection or test is completed the part can still be used.

    In contrast to NDT, other tests are destructive in nature and are therefore done on a limited number of samples (“lot sampling”), rather than on the materials, components, or systems actually being put into service.

    What is Bandwidth – Definition, Meaning & Explanation

    To summarize, bandwidth is the amount of data that can be transferred per unit of time. Internet bandwidth is currently measured in units of Mbps, or million bits per second.

    To firm up your understanding of bandwidth, imagine that on your home network your family streams video on multiple devices at the same time. As you can imagine, each stream of video requires a lot of data per second to keep the videos playing smoothly. If your streaming on more devices than your allotted bandwidth can support, you will start to hit your limit on how much data can be transferred and per second, and some of the devices will start buffering.

    Types of customer loyalty programs | YouTube

    A customer loyalty program is a rewards program that a company offers customers to encourage them to continue to shop with them.

    Traditionally, loyalty programs involved the business issuing the customer a loyalty card (variously called a rewards card or advantage card) which was visually similar to a credit card. The customer would swipe this card at every purchase and then get discounts on their current purchase or points toward a future purchase.

    More recently, companies have been using mobile online loyalty programs. Instead of swiping a loyalty card at checkout, the customer opens an app and shows a QR code that gets scanned at the register. The scanning process has moved from cards to phones but the rewards part has mostly remained the same.
