From twisted pair line one of types of port of Ethernet equipment which is utilized. 1.2nd of the terminal it transmits in, 3 - those where 6th reception is allotted to. Port of network card this type.
In order to be able to receive the signal from the MDI port, MDI and sending and receiving insert and those of the type which is substituted are called MDI-X (MDI Crossover) with. The port of the hub and the switch is this type.
In the connection of MDI and the straight cable, MDI and the cross cable is used in the connection of MDI-X. Recently, distinguishing the port type of partner automatically, the hub which had thefunction which connects is many, distinction of the port and proper use of the cable have become without necessity.

From twisted pair line one of types of port of Ethernet equipment which is utilized. 1.2nd in reception of the terminal, 3 - those where 6th transmission is allotted to. Port of hub and switch of former times this type. As for port such as network card, as for MDI-X arrangement of sending and receiving is MDI of opposite.
In the connection of MDI and MDI-X the straight cable, MDI and the cross cable is used in the connection of MDI-X. Recently, distinguishing the port type of partner automatically, the hub which had the distinction of the port and proper use of the cable have become without necessity. |

The recording type which raises the bulk compressibility of the data which records to MD, record possible time 2 times or 4 times (320 minutes) it expands. As for compressed system ATRAC3 which improves ATRAC which is adopted with MD is used. As for bit rate of 2 time mode with 132kbps and 4 time mode 66kbps. In order with 4 time mode to raise compressed efficiency, the compression by the joint stereo is done. As for monaural long haul sound recording mode 2 times, either 4 time mode is not prepared. But until recently to playing back & to record with the MDLP corresponding player it is possible MD which is recorded with standard, when the track/truck which is recorded with

DRAM Because it can do refreshment operation and access simultaneously, the high speed of 600MB/s data transfer actualizes. Because tip/chip size becomes large, there is a fault that cost is attached high. It is utilized with the graphic accelerator of part.

as for capacity the same as MD 140MB. Because the shutter is larger than for music MD, as one for music MD it is not possible to divert. Data rate being only a constant velocity CD suitable 1.2Mbps, because also the corresponding equipment is little, it did not spread excessively excluding part such as music compilation use. There is MD DATA2 as a succession standard, has the capacity of 650MB and the transfer rate of |
