Wire Frame

dados entre as portas do dispositivo. Um switch reconhece o endereço físico (endereço MAC) dos dispositivos a ele conectado para regular o fluxo de tráfego através da rede. Quando uma mensagem alcança um switch, o mesmo checa o endereço de destino no frame de dados e o compara com sua tabela de endereços. Se o endereço corresponder a um dos dispositivos conectados em uma de suas portas, ele retransmite a mensagem somente para aquela porta. Assim, a transmissão de dados em um switch é…

computadores sem a necessidade do uso de cabos – sejam eles telefônicos, coaxiais ou óticos – sua comunicação é feita por meio de equipamentos que usam radiofrequência, via ondas de rádio ou via infravermelho. A palavra Wireless provém do inglês: wire (fio, cabo); less (sem); ou seja: sem fios. Alguns usos da Tecnologia Sem Fio Tipos de Redes sem Fio Wireless Personal Area Network (WPAN) Uma WPAN (Wireless Personal Area Network) é um tipo de rede onde vários…

suspended. Nylon monofilament fishing line, as shown above, is knotted to the middle of the third cross-beam at the back of the ladder, one above the brace bearing the little white box, about which more later. Using a ladder or similar movable support frame allows setting up the balance in the middle of the room. This is important because we are bending spacetime in the basement, in this case an underground storage room at Fourmilab. Ground level is about even with the ceiling of…
