The AMD corporation aiming toward the succession of the PCI bus, the next generation I/O architecture which was developed. As for code name “LDT”
Data rate being highest, with 6.4GB/s, exceeds 132MB/s of PCI standard - 533MB/s largely. Also existing OS and the compatibility for the application software are considered.
At the beginning loading to the multiprocessor server is supposed, but at the same company it is the intention which gradually it keeps spreading to the personal computer and the network equipment etc widely. You have aimed also
The AMD corporation announces development in 2001 February, the NVIDIA corporation, the Sun Microsystems corporation, the Cisco Systems corporation and the Apple corporation etc and also establishes economic organization in July, being gratuitous vis-a-vis the enterprise which desires HyperTransport technology, releases specification.

The first computer virus which was discovered to 2006 February, is infected to Mac OS X.
We are disguised by the graphics file of the name, being executed the user double by clicking, we are infected. When you are infected, it is accustomed to sending the copy of the self who in user everyone who is registered to the address register via iChat which is the instant messenger of Mac OS X standard, is disguised in the graphics file, infection tries. In addition, when starting in order to execute the self, setting of the system is modified.

LED <Light-emitting diode>
Reading: [eruidei]
Full spelling: Light Emitting Diode
Field:
Semiconductor > basis technology > LED
|
When electric current is let flow, one kind of semiconductor device which radiates. When the anode with the cathode (cathode) there are two terminals, the righteousness, put negative voltage on the cathode in the anode, electric current flows at voltage of several volts/bolts, radiates. Because the blue diode which is assumed that there is a type of red, green and orange, etc is difficult recently is utilized, primary colors of light of red blue green were even. Because it is possible, to make the light of the various colors which include white with these combinations use of the display and the illumination of full color and the head etc of the optical disk has expanded. |

LED printer <LED printer>

Field:
Imaging > printer > LED printer

The printer where it makes the toner the exposure to light body come in contact making use of LED that copies to the paper by heat and pressure does printing. You can call the thing which utilizes LED in the exposure section of the laser printer.
At the page unit it assembles the data which is sent from the computer in picture image, follows to that image and it irradiates the light which in the exposure to light body which is called the drum is formed with LED, makes the toner come in contact.
Heating this, pushes to the paper and does printing. In comparison with other system such as ink jet printer, it is possible with high quality to print in high speed, but operational sound quiet, the calorific value and electric power consumption are large. |
