	Data transmission - Wikipedia, the free encyclopedia
		Data transmission is the conveyance of any kind of information from one space to another.
		A related concept to data transmission is the data transmission protocol used to make the data transfer legible.
		The speed of data transmission is governed by the Baud rate and bit rate.

	GUIDELINES FOR DESIGNING USER INTERFACE SOFTWARE : 5. Data Transmission
		Data might be transmitted by transferring a data file from one user to another, perhaps with an accompanying message to indicate that such a file transfer has been initiated.
		Data transmission by direct linking would presumably be rare, and achieved only under operational constraints, as when a supervisor links to a subordinate's terminal for reviewing and directing work.
		Data transmission functions that may need to be changed include those represented in these guidelines, namely, changes in message preparation and addressing, the initiation and control of message transmission, and the handling of received messages.

	Data Transmission
		In considering different kinds of media we are concerned, among other things, with the amount of data that can be transmitted through the medium per unit of time, the power required for the transmission, its attenuation rate, the distorsion, the error rate, the cost, and the security.
		If the transmission can take place in both directions, but not at the same time, we say that the transmission is half-duplex, and if it can take place at the same time in both directions it is full-duplex.
		Data is transmitted usually at different speeds from the cable to the computer and viceversa.

	[No title]
		This paper explores the concept of connectionless data transmission and its relationship to the more familiar concepts of connection-oriented data transfer, developing a rationale for the inclu- sion of the connectionless concept in the Reference Model as an integral part of the standard description of the OSI architecture.
		Since connectionless data transmission and connection-oriented data transfer are complementary concepts, they are best under- stood in juxtaposition, particularly since CDT is most often defined by its relationship to the more familiar concept of a connection.
		These data unit relationships are an impor- tant characteristic of connections, since they create a context for the interpretation of arriving data units that is indepen- dent of the data themselves.

	Mars Exploration Rover Mission: The Mission
		The data rate direct-to-Earth varies from about 12,000 bits per second to 3,500 bits per second (roughly a third as fast as a standard home modem).
		The data rate to the orbiters is a constant 128,000 bits per second (4 times faster than a home modem).
		They can send much more data direct-to-Earth than the rovers, not only because they can see Earth longer, but because they can operate their radio for much longer since their solar panels get light most of the time, and they have bigger antennas than the rovers.

	The Evaluation of High-Speed Multicast Data Transmission over IPv6 Networks
		With multicast data transmission, when a sender transfers a single packet toward the particular multicast group, the network copies the packet to transfer it only to the particular receivers belonging to the corresponding multicast group.
		Since the total number of packets transferred by the network with multicast data transmission is smaller than that with unicast data transmission, the possibility of inappropriate routing protocol operation due to the large amount of user packet transmission with multicast data transmission would be less than that with unicast data transmission.
		Also, the diversity of the data reception time by the receivers must be smaller than with the unicast data transmission, and the data reception delay by the recievers must be smaller than that with the unicast transmission.

	Performance Evaluation of Data Transmission Using IPSec over IPv6 Networks
		For large data transmissions, when we apply the authentication and encryption, the throughput degrades to 1/9 compared with the throughput without authentication or encryption.
		For large data transmissions, when we apply the authentication header (AH) [2] and encryption (Encapsulating Security Payload, or ESP) [3], the throughput degrades to 1/9 compared with the throughput without AH or ESP. With AH and ESP, we obtain about 10 Mbps for UDP data transmission and about 6 Mbps for a simple TCP/IP transmission.
		With the request/response data transmission, the end-to-end throughput degradation by applying the IPSec is less than that with the stream data transmission.

	gizmag Article: New data transmission record - 60 DVDs per second
		To enable telecommunications networks to cope with the phenomenal surge in data traffic as the internet population moves past a billion users, researchers are focusing on new systems to increase data transmission rates and it’s not surprising that the world data transmission record is continually under threat.
		By transmitting a data signal at 2.56 terabits per second over a 160-kilometer link (equivalent to 2,560,000,000,000 bits per second or the contents of 60 DVDs) the researchers bettered the old record of 1.28 terabits per second held by a Japanese group.
		Data is transmitted in fiber-optic cables using ultrashort pulses of light and is normally encoded by switching the laser on and off.

	Security: Secure Internet Data Transmission. (Site not responding. Last check: 2007-11-07)
		Transmission security is the capability to send a message electronically from one computer system to another computer system so that only the intended recipient receives and reads the message and the message received is identical to the message sent.
		Transmission is more secure over wire because an eavesdropper or hacker must be physically near the wire, whereas an interception of an air transmission can occur anywhere in reach of the signal.
		Data originates from individuals, not from computers, so implementing strong security policies and procedures is as important as choosing all the physical and technical barriers to your data.

	SPACE.com -- Columbia's Final Data Transmission Sends Mixed Signals
		The last two seconds of data, which follow 25 seconds of nothing, indicate that there was an input to disengage the autopilot system, the official said.
		The data also suggest that the four steering jets that automatically began firing to try to compensate for the increased drag on the left side of the spacecraft were no longer able to counteract the forces, the official said.
		The data also suggest there were no readings coming from Columbia's left orbital maneuvering system in the final two seconds, which could mean it broke off or was badly damaged along with the left wing, said the official close to the investigation.

	Data Transmission
		Data communications is no longer restrained by the minute bandwidth of a telecommunications voice channel (less than 4 kHz).
		Also, data transmission discussions go beyond the bounds of the transmission media and terminal equipment, and it is necessary to have a feel for the network as a whole.
		To explore the fascinating world of data communications it is instructive to start by considering the translation of digital signals to a condition suitable for transmission over analog voiceband telephone circuits.

	Secure data transmission methods (Site not responding. Last check: 2007-11-07)
		One method of secure data transmission often used in conjunction with PKI to encrypt and authenticate large data files, is secure file transfer protocol (FTP).
		It is wise to view such transmissions, if the data travels outside an organization, as any message sent over the Internet, meaning it's subject to interception and, unless properly protected, misuse.
		When transmitting sensitive data between applications, it is sound and good security practice to evaluate the encryption capabilities of the application(s) and implement an encryption solution beforehand.
