One kind of worm which became popular in around 2005 August, is infected to Windows. There are several subspecies. You are infected to Windows 2000/XP/Server 2003, but if it has updated is above such as service pack, you are not infected.

TCP port 445th of the object computer to access Zotob in, the plug and play of Windows (PnP: You are infected Plug and Play) it exists in function making use of the vulnerability which is called “MS05-039”. The computer which is infected besides the fact that infection to the other computer is tried with similar method, connecting to the IRC server of specification, receives the order of the attack person, sets up DoS attack to the Web sight of specification, executes the program which was sent.

The portable audio player of the hard disk built-in which the American Microsoft corporation announces in 2006 July. In the United States 2006 November sale is anticipated. It is made the product which opposes to iPod which is the portable audio player of the American Apple corporation.

Details of product specification are not announced at 2006 August point in time formally, but the hard disk of 30GB, the screen of 3 inches, it loads the FM tuner, with the personal computer you connect with USB 2.0 it is assumed that. In addition it is anticipated that also the radio communication with 802.11b/g becomes possible.

By the fact that it corresponds to the radio communication with 802.11b/g, the personal computer is not used by way of the wireless LAN and estimate such that it becomes possible directly to download to purchase music is done. In addition, you connect P2P between the plural Zune terminals, it is said that the streaming to transmit to the other terminal it is possible the music which is retained in one terminal. In addition, it is expected that it is possible to be linked with XBox and the portable telephone etc which are the game machine of the Microsoft corporation.

The hidden-surface removal in 3 dimensional graphics (detecting the object and the surface which are hidden with the object which is forward the gaze the processing which it tries not to draw) one of methods. The picture is formed gives the information in each pixel regarding depth other than lust information, the case where it draws in the picture, comparing the depth information of the pixel in the same coordinate, most the technique which writes just those which are forward to the picture. The memory territory for the depth information which is used with this method is called the Z buffer. Because algorithm is simple, it is easy to convert to hardware this method, but the territory for the Z buffer must be guaranteed in memory, because, a more memory it is needed by comparison with other method.
