The ISQ symbols for the bit and byte are bit and B, respectively.In the context of data-rate units, one byte consists of 8 bits, and is synonymous with the unit octet.The abbreviation bps is often used to mean bit/s, so that when a 1 Mbps connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s (megabyte per ...

The prior Ethernet speed was 10 Mbit/s. Of the Fast Ethernet physical layers, 100BASE-TX is by far the most common. Fast Ethernet was introduced in 1995 as the IEEE 802.3u standard [1] and remained the fastest version of Ethernet for three years before the introduction of Gigabit Ethernet. [2]
The competing MGBASE-T Alliance, stating the same faster Gigabit Ethernet objectives, was founded in December 2014. [15] In contrast to NBASE-T, the MGBASE-T said that their specifications would be open source. [16] IEEE 802.3's "2.5G/5GBASE-T Task Force" started working on the 2.5GBASE-T and 5GBASE-T standards in March 2015. [17]
Autonegotiation is a signaling mechanism and procedure used by Ethernet over twisted pair by which two connected devices choose common transmission parameters, such as speed, duplex mode, and flow control. In this process, the connected devices first share their capabilities regarding these parameters and then choose the highest-performance ...
Gigabit Ethernet was the next iteration, increasing the speed to 1000 Mbit/s. The initial standard for Gigabit Ethernet was produced by the IEEE in June 1998 as IEEE 802.3z , and required optical fiber . 802.3z is commonly referred to as 1000BASE-X, where -X refers to either -CX, -SX, -LX, or (non-standard) -ZX.
Terabit Ethernet (TbE) is Ethernet with speeds above 100 Gigabit Ethernet. The 400 Gigabit Ethernet ( 400G , 400GbE ) and 200 Gigabit Ethernet ( 200G , 200GbE ) [ 1 ] standard developed by the IEEE P802.3bs Task Force using broadly similar technology to 100 Gigabit Ethernet [ 2 ] [ 3 ] was approved on December 6, 2017.
