ALSO CALLED:
Gigabit-ethernet,
Ethernet Gigabit
DEFINITION: In data communications, a gigabit is one billion bits, or 1,000,000,000 (that is, 109) bits. It's commonly used for measuring the amount of data that is transferred in a second between two telecommunication points. For example, Gigabit Ethernet is a high-speed form of Ethernet (a local area network technology) that can provide data transfer rates of about 1 gigabit per second. Gigabits per second

Ethernet 10/100/1000 Copper Taps, Passive or Active?
sponsored by Gigamon
WHITE PAPER:
This article presents an overview of the various Ethernet 10/100/1000 physical layer technologies for the copper medium. It discusses the pros and cons of active versus passive tapping and why active tapping is preferred for Gigabit Ethernet running over the copper medium. The switch-over behavior of active relay-based tapping is also presented.

GIGABIT ETHERNET DEFINITION (continued): … In data communications, a gigabit is one billion bits, or 1,000,000,000 (that is, 109) bits. It's commonly used for measuring the amount of data that is transferred in a second between two telecommunication points. For example, Gigabit Ethernet is a high-speed form of Ethernet (a local area network technology) that can provide data transfer rates of about 1 gigabit per second. Gigabits per second is usually shortened to Gbps. Some sources define a gigabit to mean 1,073,741,824 (that is, 230) bits. Although the bit is a unit of the binary number system, bits in data communications are discrete signal pulses and have historically been counted using the decimal number system. For example, 28.8 kilobits per second (Kbps) is 28,800 bits per second. Because of computer architecture and memory address boundaries, bytes are always some multiple or exponent of two. See kilobyte, etc. Gigabit Ethernet definition sponsored by SearchNetworking.com, powered by WhatIs.com an online computer dictionary
