Netgears 10/100 dual-speed cardbus ethernet pc card is a 32-bit, high-performance adapter that allows any cardbus-equipped computer to connect to an ethernet or fast ethernet network. Model fa511 supports hot-swapping, allowing you to insert and remove it as necessary, without having to turn off or reset your pc. With a compact, dongle-free design, plug-and-play simplicity, and pci-like performance, the model fa511 unleashes the power of todays notebook pcs, allowing you to keep pace with demanding applications and advanced desktop technologies. Features: cardbus support: cardbus is a 32-bit bus-mastering architecture that operates at pci local-bus speeds of up to 33 mhz, yielding a peak bandwidth of 132 mb/sec. Unlike 16-bit pc cards, which operate at slower isa bus speeds of 8 mhz using an isa-like asynchronous protocol, cardbus provides a fast 32-bit multiplexed address/data path that allows full access to fast ethernets bandwidth. By utilizing internal bus speeds, cardbus can operate at speeds six times faster than a 16- bit pc card and five times faster than a 100 mbps pc card. In addition, cardbus pc cards operate at 3.3 Volts, saving power and conserving your pcs battery life. Bus-mastering capability: model fa511 features leading-edge bus-mastering capabilities to optimize throughput while maintaining low cpu utilization. Bus mastering allows the fa511 to assume control of your pcs system bus, accelerating data transfers. 16-Bit pc cards, by comparison, act as a bus slave and pass data through the cpu before sending it to the host system. This slows data transfers and strain your pcs processor. Low voltage: the model fa511 consumes a low 3.3 Volts of power. Low power consumption prolongs your pcs battery life, which allows you to run your pc longer without needing to recharge it or use a power supply. Robust: designed specifically to harness the power of the latest networking technology with 32-bit ,10/100 performance. Simple to use: plug and play makes installation a snap.
