IEEE (the American Institute of Electrical and $electronic Engineer) with it was approved in 2001 December, standard of fixing radio communication. In addition, the working group of the IEEE 802 commission which deliberated the same standard.

10 - To use the band of 66GHz, radius approximately 50km (30 miles) cover with 1 antennas, being maximum, the communication of 70Mbps is possible. However, it can communicate in only the range where the way is clear.

Presently the telephone line and the terminal part of the member type communication network which the optical fiber has borne (generally known “rust one mile”) with you suppose that it utilizes unlike the wireless LAN which supposes that you use in communication inside the building. The member type access net by IEEE 802.16 “Wireless MAN” (radio MAN: Wireless Metropolitan Area Network) with you say. Attention is attracted as the expedient which offers broadband connection service cheaply even at the area whose population density is low.

The memory territory which the file operation function of MS-DOS utilizes, houses the information regarding the file.

The case where the program which operates on MS-DOS opens the file inside the disk, the file operation function which DOS builds in there is many a thing which is called. At that time, guaranteeing the territo(one of DOS function call)ry in memory, it manages the information regarding the file. This is FCB.

As for the contents of FCB, the file pointer which record length of the data which the user appoints, access method, the file which corresponds somewhere with respect to disk drive exists the pointer etc of position of the data which the user is reference shows, and in inside the file which is opened information is included.
