Office Noah developed, the compressed extension software of the animated picture data. The portable information terminal of sharp (PDA) it is adopted with “the movie copying mail” “of Zaurus” and the J phone.

It was sold in 2001 August for the first time to be adopted by “Zaurus MI-E21”, it became possible by the fact that “Zaurus” and the video record card are used to do video video recording with Zaurus itself.

“Nancy Codec” has adopted individual compressed extension system, high pressure reduction ratio application size being small-sized, same by comparison with the file of MPEG-4 type of bit rate low reproducibility of animated picture at the time of contrast is superior compared

NAND operation

Reading: NAND
Full spelling: Not AND
Field:
Semiconductor > basis technology > NAND

When at one of the basic logical operation which the logic circuit does, all input “the truth” (or 1) is only, when output becomes “the fake” (or “0”) with, it is other than that, it is the kind of operation where output (or 1) with becomes true. AND (and operation) in the result of operation NOT (denial) those which did operation.

The logic circuit which does this operation is called the “not-and operation circuit” the “NAND operational circuit” “NAND gate” and so on. Because in the design of the actually logic circuit compared to And OR NAND and NOR are easier to make, this one is used.

NAND type flash memory

Reading: NAND abnormal play

flash

memory
Full spelling: NAND-type flash memory
Field:
Semiconductor > memory > NAND type flash memory
Mobile > memory card > NAND type flash memory

The flash memory technology which Toshiba developed in 1987. It designates that it utilizes in retention conveyance and the like of the data in place of the disk as main use.

It has become the specification where speed of elimination and entry is suited for large increasing capacity fast unlike the NOR type flash memory in order to accommodate the program, but only reading and writing at the block unit it is possible, there is also a fault that random access is slow.

We are applied by the memory card media widely, we are utilized the compact flash, as the storage cell of the smart media and the SD memory card etc.

Napa Centrino Duo

Alias:
[sentorino] duo, Intel Centrino Duo mobile technology and [napa]
Field:
Microprocessor > x86/Intel > Intel > Napa

With brand name of the hardware platform for the Mobile equipment which the Intel corporation announced in 2006 January, begins the notebook PC, microprocessor “Intel Core Duo” and chip set “Intel 945” name of the package which combines three of the series and wireless LAN tip/chip “Intel PRO/Wireless 3945ABG”. It is the product which is known development cord/code name “Napa” ([napa]) as.

Being core with the microprocessor Core Duo which becomes the first dual core product as for Mobile, has loaded two processor cores onto one tip/chip. In the system which adopts Centrino Duo, while decreasing approximately 3 percentage electric power consumption than the product until recently, simultaneously as expected the time, at the same company it has expressed maximum of 7 tenths close efficiency improvement “progressive” concerning this evolution.

Napster napusuta

Reading: [napusuta]
Alias:
Nap star
Field:
Internet > file sharing > Napster
Multimedia > sound/music > music transmission service > Napster

It was announced in 1999 January, the application software which does the exchange of the music data between the individuals via Internet. In addition, enterprise of the same name which does the management of development distribution and the music list joint ownership server of the same software. Or, the music transmission service which the same company starts in 2003 October.

Napster as music file sharing software Shaun [huaningu] which is the student of the eastern university north that time (Shawn Fanning) being something which the person develops & releases, transmits to the server where the Napster corporation manages the list of the audio file of the MP3 type which is retained in the personal computer of the user. It searches the music file which the other user possesses mutually due to the fact that the user in the world shares this, it is possible to download. The central server has done only the offer of the file inquiry database and the management of connection of the user, exchange of the music data itself is done by the direct connect between the users.

NAPT IP masquerade

Full spelling: Network Address Port Translation
Alias:
IP masquerade
Field:
Network technology > TCP/IP > NAPT

At the enterprise and the like which is connected to Internet, one global the technology which shares IP address with the plural computers. Only while organizing it is actualized the IP address which passes (local address) with, address on Internet (global address) by converting transparently mutually.

Because it is converted dynamically to the port number of TCP/UDP unlike NAT, it is possible with one global address to connect simultaneously from the plural machines. However, because conversion of port number is done, there is restriction such that method of kind of using which from Internet side starts connection in the machine inside is not possible, cannot utilize either ICMP. With the recent broadband rooter and the like there are also some which do individually mounting in order to ease such restriction.
