10Base-T

Is one of of the Ethernet standards as specified in IEEE 802.3, which utilizes twisted pair wire and an RJ45 connector. "10" specifies 10Mbps, "Base" specifies baseband signalling, and "T" specifies Twisted pair wire. See also Ethernet.

10Base-F

Is one of the Ethernet standards as specified in IEEE 802.3, which utilizes optical fiber cable as the transmission medium, also known as fiber optic cable. See also Ethernet.

10 Gigabit Ethernet

Is an Ethernet transmission protocol that provides data transfer up to 10 gigabits per second, which is 10 billion bits per second. Also see gigE which provides up to 1 billion bits per second.

1U

One Rack Unit, is equal to 1.75 inches in height, and is used to determine how much rack space a web customer is renting from a data center, web host provider or MSP.

95th Percentile

is a method used by ISP’s and Host Providers to calculate the bandwidth used. 95th Percentile is defined as 95% of the time one uses bandwidth less than this amount and 5% of the time one uses bandwidth above this amount. Typically, samples are taken systematically somewhere between 10-30 minute intervals depending upon the Provider, and averaged over a 30 day period. A 95th Percentile represents a “median” of 95 percent of the time, versus an “average” figure. 95 Percentile calculations are common for users requiring high speed Internet connections with high bandwidth capability.
