DOCSIS employs a mixture of deterministic access methods for upstream transmissions, specifically time-division multiple access (TDMA) for DOCSIS 1.0/1.1 and both TDMA and S-CDMA for DOCSIS 2.0 and 3.0, with a limited use of contention for bandwidth reservation requests. In TDMA, a cable modem requests a time to transmit and the CMTS grants it ...

For example, a single link PCIe 3.0 interface has an 8 Gbit/s transfer rate, yet its usable bandwidth is only about 7.88 Gbit/s. z Uses 8b/10b encoding , meaning that 20% of each transfer is used by the interface instead of carrying data from between the hardware components at each end of the interface.
Link aggregation increases total throughput beyond what a single connection could sustain, and provides redundancy where all but one of the physical links may fail without losing connectivity. A link aggregation group ( LAG ) is the combined collection of physical ports.
The BT Home Hub 1.0, 1.5 and 2.0 devices connect to the Internet using a standard ADSL connection. The BT Home Hub 3 and 4 models support PPPoA for ADSL and PPPoE for VDSL2, in conjunction with an Openreach-provided VDSL2 modem to support BT's FTTC network (BT Infinity).

A 1994 Software Publishers Association found that although 60% of computers in US households had a modem, only 7% of households went online. [52] A CEA study in 2006 found that dial-up Internet access was declining in the US. In 2000, dial-up Internet connections accounted for 74% of all US residential Internet connections.
The written USB 3.0 specification was released by Intel and its partners in August 2008. The first USB 3.0 controller chips were sampled by NEC in May 2009, [4] and the first products using the USB 3.0 specification arrived in January 2010. [5] USB 3.0 connectors are generally backward compatible, but include new wiring and full-duplex operation.
