"Digital electronics, or digital (electronic) circuits, represent signals by discrete bands of analog levels, rather than by a continuous range. All levels within a band represent the same signal state. Relatively small changes to the analog signal levels due to manufacturing tolerance, signal attenuation or parasitic noise do not leave the discrete envelope, and as a result are ignored by signal state sensing circuitry. ...
Digital techniques are useful because it is easier to get an electronic device to switch into one of a number of known states than to accurately reproduce a continuous range of values. ...
An advantage of digital circuits when compared to analog circuits is that signals represented digitally can be transmitted without degradation due to noise. ...
In a digital system, a more precise representation of a signal can be obtained by using more binary digits to represent it. While this requires more digital circuits to process the signals, each digit is handled by the same kind of hardware. ...
Computer-controlled digital systems can be controlled by software, allowing new functions to be added without changing hardware. Often this can be done outside of the factory by updating the product's software. So, the product's design errors can be corrected after the product is in a customer's hands.
Information storage can be easier in digital systems than in analog ones. The noise-immunity of digital systems permits data to be stored and retrieved without degradation. ...
In a digital system, as long as the total noise is below a certain level, the information can be recovered perfectly." [Digital electronics. Wikipedia]

This circle-spoke diagram sample illustrates the proximity marketing.
"Proximity marketing is the localized wireless distribution of advertising content associated with a particular place. Transmissions can be received by individuals in that location who wish to receive them and have the necessary equipment to do so.
Distribution may be via a traditional localized broadcast, or more commonly is specifically targeted to devices known to be in a particular area.
The location of a device may be determined by:
(1) A cellular phone being in a particular cell.
(2) A Bluetooth or WiFi device being within range of a transmitter.
(3) An Internet enabled device with GPS enabling it to request localized content from Internet servers.
(4) A NFC enabled phone can read a RFID chip on a product or media and launch localized content from internet servers.
Communications may be further targeted to specific groups within a given location, for example content in tourist hot spots may only be distributed to devices registered outside the local area.
Communications may be both time and place specific, e.g. content at a conference venue may depend on the event in progress.
Uses of proximity marketing include distribution of media at concerts, information (weblinks on local facilities), gaming and social applications, and advertising." [Proximity marketing. Wikipedia]

This interior design sample depicts the layout of furniture, equipment and appliences on the dance studio floor plan.
"A dance studio is a space in which dancers learn or rehearse. The term is typically used to describe a space that has either been built or equipped for the purpose.
A dance studio normally includes a smooth floor covering or, if used for tap dancing, by a hardwood floor. The smooth vinyl floor covering, also known as a performance surface and commonly called "marley", is generally not affixed permanently to the underlying floor and can be rolled up and transported to performance venues if needed. ...
Other common features of a dance studio include a barre, which can be either fixed to the wall or be a standalone move-able device that is approximately waist height and used as a means of support. As music is an integral part of dance, nearly all dance studios have a sound system for playing CD's or music via a Bluetooth enabled device; a remote control is essential for the sound system to make it easy for the instructor to repeat musical passages as needed. A piano is still commonly used to accompany ballet and tap dance, especially in professional studios. In purpose-built dance studios, it is typical for at least one wall to be covered by floor to ceiling mirrors, which are used by dancers to see their body position and alignment. Other essentials in any dance studio are a table for teacher notebooks and other instructional materials, as wall as a large wall clock." [Dance studio. Wikipedia]
