v. t. e. Wi-Fi ( / ˈwaɪfaɪ /) [1] [a] is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks, used globally in ...
The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan. The initial alternating-square design presented by the team of researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board; the pattern of position detection was found and determined by applying the least-used ratio (1:1:3:1:1) in black ...
Process Visitors to Derby Museum using a mobile phone to scan a QRpedia QR code. When a user scans a QRpedia QR code on their mobile device, the device decodes the QR code into a Uniform Resource Locator (URL) using the domain name "languagecode.qrwp.org" and whose path (final part) is the title of a Wikipedia article, and sends a request for the article specified in the URL to the QRpedia web ...

A UPC-A barcode. A barcode or bar code is a method of representing data in a visual, machine-readable form. Initially, barcodes represented data by varying the widths, spacings and sizes of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called barcode ...
Rectangular Micro QR Code (also known as rMQR Code) is two-dimensional (2D) matrix barcode invented and standardized in 2022 [1] by Denso Wave as ISO/IEC 23941. [2] rMQR Code is designed as a rectangular variation of QR code and has the same parameters and applications as original QR code. But rMQR Code is more suitable for the rectangular ...
Universally unique identifier. A Universally Unique Identifier ( UUID) is a 128-bit label used for information in computer systems. The term Globally Unique Identifier ( GUID) is also used, mostly in Microsoft systems. [1] [2] When generated according to the standard methods, UUIDs are, for practical purposes, unique.
Windows Live Barcode (codenamed Confucius) was a part of Microsoft 's Windows Live services. It allowed users to transfer information between various media (PCs, billboards, magazines etc.) and handsets via Quick Response Code ( QR Code ), a two-dimensional matrix barcode. It provided a method for people to exchange information and use various ...
Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.
Wi-Fi 6, or IEEE 802.11ax, is an IEEE standard from the Wi-Fi Alliance, for wireless networks ( WLANs ). It operates in the 2.4 GHz and 5 GHz bands, [9] with an extended version, Wi-Fi 6E, that adds the 6 GHz band. [10] It is an upgrade from Wi-Fi 5 ( 802.11ac ), with improvements for better performance in crowded places.
