It’s an example of Apple making design decisions that impact function for the sake of form, a decision the company’s made at many points in its past (for example, its decision to remove the optical drive in its 2.

There Are No Functional Adapters Yet. Naturally, you might think there’s some sort of workaround, or an adapter that can easily fix this incompatibility issue. After all, Apple makes its own adapters for a variety of older interfaces (for instance, VGA port adapters for mirroring your i. OS device on a monitor).

Apple Is Comfortable With User- Hostile Tech. Apple’s Lightning connector is convenient for Apple, but not so much for the rest of us. It’s only available on Apple’s i. OS devices, making switching to, say, an Android device an inconvenient and pricey decision—you’ll need new cables, headphones, docks etc. To play nice with others, Apple should have either left the 3. Phone, or switched to USB- C, which is what every other cell phone manufacturer is doing. And while their move towards incompatibility with other company’s devices isn’t surprising, it does seem a little weird that they’d build this kind of glaring incompatibility into their two most recent devices—the i. Phone 7 and the latest Mac. Book pro. The decision to exclude the Lightning port from its Macs—and not to publicly address the compatibility issues —also runs counter to its history of transition tools. During the company’s switch from Power. PC to Intel processors, it released the Rosetta translator software to keep Power. PC apps running on Intel- powered Macs. When the Mac. Book Air debuted without an optical drive, the company’s external Super. Drive optical drive eased the transition. My theory? The removal of the headphone jack and inclusion of Lightning Ear. Pods is simply a stop- gap to the company’s true goal of forcing you to go wireless and buy Air. Pods or Beats Bluetooth headphones.

I’ve been lamenting the demise of the Unix philosophy: tools should do one thing, and do it well. The ability to connect many small tools is better than having a single tool that does everything poorly. That philosophy was great, but hasn’t survived into the Web age. Unfortunately, nothing better has come along to replace it. Instead, we have “convergence”: a lot of tools converging on doing all the same things poorly. The poster child for this blight is Evernote. It is a generally accepted standard that editors should attempt to follow, though it is best treated with common sense, and occasional exceptions may apply. The source code for a particular piece of software may be contained in a single file or many files. Though the practice is uncommon, a program's source code can be.

I started using Evernote because it did an excellent job of solving one problem. I’d take notes at a conference or a meeting, or add someone to my phone list, and have to distribute those files by hand from my laptop to my desktop, to my tablets, to my phone, and to any and all other machines that I might use. But as time has progressed, Evernote has added many other features. Some I might have a use for, but they’re implemented poorly; others I’d rather not have, thank you. I’ve tried sharing Evernote notes with other users: they did a good job of convincing me not to use them. Photos in documents? I really don’t care.

El wifi (sustantivo común en español, incluido en el Diccionario de la ASALE[1] y proveniente de la marca Wi- Fi)[2] es un mecanismo de conexión de dispositivos electrónicos de forma inalámbrica. Los dispositivos habilitados con wifi (como una computadora personal, un televisor inteligente, una videoconsola, un teléfono inteligente o un reproductor de música) pueden conectarse a internet a través de un punto de acceso de red inalámbrica. Dicho punto de acceso tiene un alcance de unos veinte metros en interiores, alcance que incrementa al aire libre. Wi- Fi es una marca de la Alianza Wi- Fi, la organización comercial que adopta, prueba y certifica que los equipos cumplen con los estándares 8.

I loafe and invite my soul. Etimología. El término wifi, sustantivo común escrito normalmente en redonda (sin comillas ni cursiva), [2] proviene de la marca comercial Wi-Fi. La WECA, el consorcio que desarrolló esta tecnología, contrató a una empresa de publicidad para que le diera un nombre a su estándar, de tal manera que fuera fácil de entender y recordar. Phil Belanger, miembro fundador de WECA, actualmente llamada Alianza Wi- Fi, apoyó el nombre Wi- Fi: [cita requerida]"Wi- Fi" y el "Style logo" del Yin Yang fueron inventados por la agencia Interbrand. Nosotros (Wi. Fi Alliance) contratamos a Interbrand para que nos hiciera un logotipo y un nombre que fuera corto, tuviera mercado y fuera fácil de recordar. Necesitábamos algo que fuera algo más llamativo que “IEEE 8. Secuencia Directa”. Interbrand creó nombres como “Prozac”, “Compaq”, “One. World”, “Imation”, por mencionar algunos. Incluso inventaron un nombre para la compañía: VIATO.”Phil Belanger. La similitud con la marca Hi- Fi (del inglés high fidelity; usado frecuentemente en la grabación de sonido) ha hecho creer, erróneamente, que el término Wi- Fi es una abreviación de wireless fidelity (traducido al español, fidelidad inalámbrica). Esta nueva tecnología surgió por la necesidad de establecer un mecanismo de conexión inalámbrica que fuese compatible entre distintos dispositivos. Buscando esa compatibilidad, en 1. Com, Airones, Intersil, Lucent Technologies, Nokia y Symbol Technologies se unieron para crear la Wireless Ethernet Compatibility Alliance, o WECA, actualmente llamada Alianza Wi- Fi. El objetivo de la misma fue designar una marca que permitiese fomentar más fácilmente la tecnología inalámbrica y asegurar la compatibilidad de equipos. De esta forma, en abril de 2. WECA certifica la interoperabilidad de equipos según la norma IEEE 8. Wi- Fi. Esto quiere decir que el usuario tiene la garantía de que todos los equipos que tengan el sello Wi- Fi pueden trabajar juntos sin problemas, independientemente del fabricante de cada uno de ellos.

Son los siguientes: Los estándares IEEE 8. IEEE 8. 02. 1. 1g e IEEE 8. GHz está disponible casi universalmente, con una velocidad de hasta 1. Mbit/s, 5. 4 Mbit/s y 3. Mbit/s, respectivamente. En la actualidad ya se maneja también el estándar IEEE 8. WIFI 5, que opera en la banda de 5 GHz y que disfruta de una operatividad con canales relativamente limpios. La banda de 5 GHz ha sido recientemente habilitada y, además, no existen otras tecnologías (Bluetooth, microondas, Zig. Bee, WUSB) que la estén utilizando, por lo tanto existen muy pocas interferencias. Su alcance es algo menor que el de los estándares que trabajan a 2,4 GHz (aproximadamente un 1. Existen otras tecnologías inalámbricas como Bluetooth que también funcionan a una frecuencia de 2,4 GHz, por lo que puede presentar interferencias con la tecnología wifi. Debido a esto, en la versión 1. Bluetooth por ejemplo se actualizó su especificación para que no existieran interferencias con la utilización simultánea de ambas tecnologías, además se necesita tener 4. Seguridad y fiabilidad[editar]Uno de los problemas a los cuales se enfrenta actualmente la tecnología wifi es la progresiva saturación del espectro radioeléctrico, debido a la masificación de usuarios; esto afecta especialmente en las conexiones de larga distancia (mayor de 1. En realidad el estándar wifi está diseñado para conectar ordenadores a la red a distancias reducidas, cualquier uso de mayor alcance está expuesto a un excesivo riesgo de interferencias. Un muy elevado porcentaje de redes son instalados sin tener en consideración la seguridad convirtiendo así sus redes en redes abiertas (o completamente vulnerables ante el intento de acceder a ellas por terceras personas), sin proteger la información que por ellas circulan. De hecho, la configuración por defecto de muchos dispositivos wifi es muy insegura (routers, por ejemplo) dado que a partir del identificador del dispositivo se puede conocer la clave de éste; y por tanto acceder y controlar el dispositivo se puede conseguir en solo unos segundos. El acceso no autorizado a un dispositivo wifi es muy peligroso para el propietario por varios motivos. El más obvio es que pueden utilizar la conexión. Pero, además, accediendo al wifi se puede supervisar y registrar toda la información que se transmite a través de él (incluyendo información personal, contraseñas…). La forma de hacerlo seguro es seguir algunos consejos: [3][4]Cambios frecuentes de la contraseña de acceso, utilizando diversos caracteres, minúsculas, mayúsculas y números. Se debe modificar el SSID que viene predeterminado. Desactivar la difusión de SSID y DHCP. Configurar los dispositivos conectados con su IP (indicar específicamente qué dispositivos están autorizados para conectarse). Utilización de cifrado: WPA2. Filtrar los dispositivos conectados mediante la dirección MAC. Existen varias alternativas para garantizar la seguridad de estas redes. Las más comunes son la utilización de protocolos de cifrado de datos para los estándares wifi como el WEP, el WPA, o el WPA2 que se encargan de codificar la información transmitida para proteger su confidencialidad, proporcionados por los propios dispositivos inalámbricos. La mayoría de las formas son las siguientes: WEP, cifra los datos en su red de forma que sólo el destinatario deseado pueda acceder a ellos. Los cifrados de 6. WEP. WEP codifica los datos mediante una “clave” de cifrado antes de enviarlo al aire. Este tipo de cifrado no está recomendado debido a las grandes vulnerabilidades que presenta ya que cualquier cracker puede conseguir sacar la clave, incluso aunque esté bien configurado y la clave utilizada sea compleja. WPA: presenta mejoras como generación dinámica de la clave de acceso. Las claves se insertan como dígitos alfanuméricos. IPSEC (túneles IP) en el caso de las VPN y el conjunto de estándares IEEE 8. X, que permite la autenticación y autorización de usuarios. Filtrado de MAC, de manera que solo se permite acceso a la red a aquellos dispositivos autorizados. Es lo más recomendable si solo se va a usar con los mismos equipos, y si son pocos. Ocultación del punto de acceso: se puede ocultar el punto de acceso (router) de manera que sea invisible a otros usuarios. El protocolo de seguridad llamado WPA2 (estándar 8. WPA. En principio es el protocolo de seguridad más seguro para Wi- Fi en este momento. Sin embargo requieren hardware y software compatibles, ya que los antiguos no lo son. La seguridad de una red wifi puede ser puesta a prueba mediante una auditoría de wifi. Sin embargo, no existe ninguna alternativa totalmente fiable, ya que todas ellas son susceptibles de ser vulneradas. Dispositivos[editar]Existen varios dispositivos wifi, los cuales se pueden dividir en dos grupos: dispositivos de distribución o de red, entre los que destacan los enrutadores, puntos de acceso y repetidores; y dispositivos terminales que en general son las tarjetas receptoras para conectar a la computadora personal, ya sean internas (tarjetas PCI) o bien USB. Dispositivos de distribución o de red. Los puntos de acceso son dispositivos que generan un set de servicio, que podría definirse como una red wifi a la que se pueden conectar otros dispositivos. |
