	What is bits per second? - a definition from Whatis.com - see also: bps, bit/sec, bit per second
		In data communications, bits per second (abbreviated bps or bit/sec) is a common measure of data speed for computer modems and transmission carriers.
		One kilobit per second (abbreviated Kbps in the U.S.; kbps elsewhere) is equal to 1,000 bps.
		One megabit per second (Mbps) is equal to 1,000,000 bps or 1,000 Kbps.

	Micro Consultants -- Bandwidth for the future...Today!
		It is expressed in cycles per second (Hertz or Hz), the bandwidth being the difference between the lowest and highest frequencies transmitted.
		The frequency is equal to or greater than the bits per second.
		If we were to consistently transmit one million bits of data per second, our bandwidth would be a constant at 1 Mbps.

	Broadband Glossary - Which-Broadband.net - Broadband Comparison Site
		DSL and cable modem, both popular consumer broadband technologies, are typically capable of transmitting 256 kilobits per second or more, approximately nine times the speed of a modem using a standard digital telephone line.
		A kilobit per second (kbps or kbit/s) is a unit of data transmission speed equal to 1,000 bits per second.
		A megabit per second (Mbps or Mbit/s) is a unit of data transmission equal to 1,000 kilobits per second or 1,000,000 bits per second.

		The second terminals of switches 434, and 434a, are connected to a junction with a first terminal of switch 435, switch 435a, respectively, a terminal of capacitor 436, capacitor 436a respectively, and the negative input of comparator 437, comparator 437a, respectively.
		The second terminals of switch 435, and 435a, are connected to a junction of a first terminal of capacitor 438a, respectively, and a first terminal of resistor 439, resistor 439a, respectively.
		The second terminals of capacitors 438 and 438a, and resistors 439 and 439a are connected to ground.

	Personal Technology -- Personal Technology from The Wall Street Journal.
		For instance, Verizon's entry-level DSL service, at 768 kilobits per second for downloads and 128 kilobits per second for uploads, is considered high-speed here.
		A megabit per second (mbps) connection moves about 1,000 times as much data every second as a kilobit per second (kbps) connection.
		A service running at 10 megabits per second is more than 13 times as fast as Verizon's base DSL service.

	New Modems Held Hostage to the Old Phone Network
		But it is a sign of how pitiful the bandwidth situation has become that an extra 10, 20 or 25 kilobits per second is precious when the technology exists today to deliver 128 kilobit- or even multimegabit-per-second connections.
		In a perfect world of perfect connections, the modems should be able to recover 8,000, eight-bit codes per second for a total of 64 kilobits per second.
		The voltage restriction means that the 56 Kbps modems cannot use some of the voltage steps at the high end of their range, thus cutting the maximum speed to around 52 kilobits per second.

	Computer-based education system - Patent 4793813
		The invention defined in claim 2 wherein the rate of data flow per receiving display terminal in said reverse channel is approximately ten percent or less of the rate of data flow in said forward channel.
		The reverse channel link, while only able to accept data rates in the kilobit per second range is able to accommodate the outputs from hundreds of user operated terminals because of the low data rates produced by user operated terminals.
		Thus, since the forward channel is able to accept data at a 1.5 megabit per second rate, the users perceive no delay in the forward channel data as it is displayed on their terminals.

	Bandwidth, and how to use it up
		But, annoyingly, there are 1024 bytes in a kilobyte, and 1048576 bytes in a megabyte; people are trying to get different prefixes used for these powers-of-two numbers to distinguish them from the normal powers-of-ten SI prefixes, but it's just not happening.
		If your connection speed is 128 kilobits per second and you're downloading data from a server that can deliver bits faster than the link can pipe them to you, you'll only get that data at 128 kilobits per second, minus whatever overhead your communications protocols impose.
		With a broadband connection with roughly 16 kilobytes per second of upstream bandwidth, that's what'll limit you.

	LGR - ARPA Network Implications
		A second characteristic of computer-to-computer communications is that the connect time to establish a conversation must be short enough that the computers or the computer users are not held up unduly when the need to access a special resource is determined.
		It is known that for useful comprehension by a human, the peak data rate for graphical material is on the order of 20 kilobits per second, which suggests the required bandwidth for console-to-computer communications.
		The ARPANET response speed of one-tenth of a second for a question and three-tenths of a second for a one-page answer is quite acceptable for a human user and for a computer program it is no worse than a slow disc.

	Technology Review: On the Road to 3G
		According to the ITU, in a high-speed train, a 3G connection should support data rates between 144 and 384 kilobits per second, three to ten times faster than a typical dial-up connection.
		At 60 mph in a car, a user should receive data at 384 to 512 kilobits per second, as fast as DSL or cable.
		A pedestrian should have 2 megabits per second, fast enough to download an entire word processing program in 10 to 15 seconds.

		The original MPEG-2 clip was 30.5 MB and had an average bit rate of 7,870.78 megabits per second.
		To get to the point where it was acceptable, I thought that clip needed two megabits per second, and before it looked good I had to give it four.
		At 256 kilobits per second, of course, it was a disaster.

		If the file is intended for users that have 28.8 kilobit per second modems, then the AM (8 kbits per second) or the FM (mono) (16 kbits per second) compression selections make sense.
		On files intended for Intranets, CD Quality (128 kbits per second) might be selected since the typical connection speed is 10 megabits per second.
		For example, most publishers will be using 16 kilobit per second compression since it allows FM quality audio over 28.8kbps modems.

	Bitrate - Wikipedia, the free encyclopedia
		In digital multimedia, bitrate is the number of bits used per unit of time to represent a continuous medium such as audio or video after source coding (data compression).
		The bit rate is quantified using the 'bit per second' (bit/s or bps) unit, often in conjunction with a SI prefix such as kilo (kbit/s or kbps), Mega (Mbit/s or Mbps), Giga (Gbit/s or Gbps) or Tera (Tbit/s or Tbps).
		Even less formally, it is common to drop the "per second", and simply refer to "a 128 kilobit audio stream" or "a 100 megabit network".

		The "SI second" (formerly called "atomic second") is now defined as equal to 9192631770 periods of the radiation corresponding to the transition between the two hyperfine levels of Cesium-133.
		This mean solar second came under international scrutiny by the CGPM in 1954, and the BIPM proposed (in 1956) a new official definition of the second: The definition of the so-called ephemeris second is based entirely on the orbital period of the Earth, which is steadier than its spin.
		The ephemeris second was the official definition of the second from 1960 to 1967.

		Kbps: Kbps stands for kilobit per second (thousands of bits per second, or bps) and is a common measure of bandwidth.
		Mbps: Mbps represents millions of bits per second and is a measure of bandwidth on a medium such as a telephone line, cable line, or optical fiber.
		Depending on the medium and the transmission method, bandwidth may also be in the Kbps range or the Gbps (billions of bits or gigabits per second) range.

		But most broadband users are limited to 256 kilobits per second, and millions still chug along at 90 to 128 kilobits per second.

		The first DSL version, which could become available as early as next year, offers download rates of up to 24 megabits per second (though in real-world deployments subscribes will probably get between 6 and 15 megabits per second, depending on their distance from the central office).

		128 kilobit is often too low, though; many tracks exhibit irritating compression artefacts at this low a bit rate, usually manifesting as odd "underwater" modulation noises.
		At 160 kilobits per second, most of these problems go away, and you still need less than 69 megabytes per hour.
