Una vez que la página solicitada ha sido cargada, el zing desaparece para aparecer a continuación a modo de pequeño recuadro en la parte superior derecha de la pantalla.

El término es del argot del sector de la seguridad informática, pero puede afactar y mucho a las actividades que una empresa realice por Internet.

En una página web donde hay imágenes realizadas en VRML se acostumbra a añadir una opción de zoom mediante la cual, a golpe de clic, se ofrecen vistas a diferentes distancias. Es de mucha utilidad para presentar la imagen de un producto en la ficha del mismo en una tienda virtual.

Z-Wave

Posted by: Margaret Rouse

Z-Wave is a wireless communication technology that is used in security systems and also business and home automation.

Z-Wave is often used in locks, security systems, lighting, heating, cooling and home appliances. Support can be integrated in products or added by retrofitting standard electronics and devices.

Z-Wave communications use low-power radio signals in the 900MHz range, separated fromWi-Fi. The system supports automatic discovery of up to 230 devices per controller. Multiple controllers can also communicate with one another and pass commands to support additional devices. Z-wave is optimized for low latency, with data rates of up to 100KB/s.

Z-Wave is marketed primarily as a security product. However, vulnerabilities have been detected that allow attackers to spoof an access point to gain control, even on encrypted versions. Like most security automation products, Z-Wave increases a system’s attack surface because it adds connected devices and associated software. To prevent networked devices from increasing the overall vulnerability of a system, it’s important to consider the security of any connected element.

Over 80 percent of commercial home security systems use Z-Wave as the protocol by which their components communicate; the Z-Wave Alliance, a global consortium organized to bring compatible devices to market, includes more than 250 manufacturers among its members.

Definición de ZigBee

 

ZigBee es el nombre de la especificación de un conjunto de protocolos de alto nivel de comunicación inalámbrica para su utilización con radiodifusión digital de bajo consumo, basada en el estándar IEEE 802.15.4 de redes inalámbricas de área personal (wireless personal area networkWPAN). Su objetivo son las aplicaciones que requieren comunicaciones seguras con baja tasa de envío de datos y maximización de la vida útil de sus baterías.

En principio, el ámbito donde se prevé que esta tecnología cobre más fuerza es en domótica, como puede verse en los documentos de la ZigBee Alliance, en las referencias bibliográficas que se dan más abajo en el documento «ZigBee y Domótica». La razón de ello son diversas características que lo diferencian de otras tecnologías:

  • Su bajo consumo.
  • Su topología de red en malla.
  • Su fácil integración (se pueden fabricar nodos con muy poca electrónica).

ZigBee Definition

Posted by Margaret Rouse

ZigBee is a mesh network specification for low-power wireless local area networks (WLANs) that cover a large area.

ZigBee was designed to provide high data throughput in applications where the duty cycle is low and low power consumption is an important consideration. (Many devices that use ZigBee are powered by battery.) Because ZigBee is often used in industrial automation and physical plant operation, it is often associated with machine-to-machine (M2M) communication and the Internet of Things (IoT). 

ZigBee is based on the Institute of Electrical and Electronics Engineers Standards Association's 802.15 specification. It operates on the IEEE 802.15.4 physical radio specification and in unlicensed radio frequencybands, including 2.4 GHz, 900 MHz and 868 MHz. The specifications are maintained and updated by the ZigBee Alliance.

As of this writing, there are three ZigBee specifications: ZigBee, ZigBee IP and ZigBee RF4CE. ZigBee IP optimizes the standard forIPv6 full mesh networks and ZigBee RF4CE optimizes the standard for partial mesh networks.
