After in year 1982 defining of standard TCP /IP which caught up with the use of system DNS. Growth Internet continue in the year 1986 delivering birth National Science Foundation Network ( NSFNET), connective all periset of totality country by 5 center super computer. This network then expand to connect various other academic network consisted of the university and consortium research into the. NSFNET then start to replace ARPANET as network research into especial in America till at March 1990 ARPANET officially disbanded. At the NSFNET builded, various founded international network and interfaced to NSFNET. Australian, nations Skandinavia, English, French, jerman, Canadian and Japan immediately join into this network.
Initially, internet only offer the service base on the text, covering remote access, email/ messaging, and also discussion of through newsgroup ( Usenet). Service base on graphical like World Wide Web ( WWW) Moment still not yet. Only service is so-called Gopher which in some cases loo like like web which we recognize in this time, except its job system which still base on the text. Progress mean reached in the year 1990 when World Wide Web start developed by CERN ( Laboratory of Particle Physics in Swiss) pursuant the proposal which is made by Team Berners-Lee. But that way, newborn first WWW Browser two year later, precisely in the year 1992 by the name of Viola. Viola launched by Pei Wei and distributed with CERN WWW. Of course this first web browser still very simple, don't as sophisticated as modern browser which we use in this time.
Breakthrough mean became of by1993 when Internic founded to run service of registration domain. At The Same Time, White House start online in Internet and government United States get away the National Information Infrastructure Act. Use Internet in commercially started at 1994 pioneered by company of Pizza Hut, and Internet Banking first time application by First Virtual. One year later;then, Compuserve, America Online, and Prodigy start to give the service access to Internet for public.

XSLT
XSLT ( eXtensible Stylesheet Language:Transformation) is a part of XSL developed previously. XSL is special Stylesheet developed as complement XML, for the fox of information at XML into other form to be can be presented in screen, printed in paper or listened by a ear. Basically process this for becoming two shares process first namely Structural Transformasi covering gathering, subdividing and sequence of data and also reconstituting, addition and abolition of tag and attribute, and secondly is process of format fox become the pixel[screen, ink in paper or tone in speaker. First process that's which then referred by XSLT, while ordinary secondly referred by XSLFO ( eXtensible Stylesheet Language:Formatting Object).
Result of XSLT can be HTML, Text of File or XML with the new format. In fact to present the document XML for more interesting seen in browser can be by Cascade Stylesheet. CSS which often used for the format of HTML can also weared for the XML. However CSS unable to conduct the complicated difuculte work's like number format denary, menjumlah, calculating mean, presenting picture, and others. To conduct the work that's we need XSLT.
XSLT Processor or ordinary referred by Parser is assistive software which its duty apply the comands in XSLT at document of source XML, and yield the good output document in the form of HTML, Text File and or XML.

XML (eXtensible Markup Language)
eXtensible Markup Language shortened by XML is special Ianguage to they form the Web page so that its consumer can do various format tag in the document. This Ianguage released by World Wide Web Consortium ( W3C) to give the more flexible ability to all programmer web compared to Hypertext Markup Language ( HTML). XML also represent the subset from Standard of Generalized Markup Language ( SGML).
XML developed by start the year 1996 and get the confession from W3C at Februari 1998. Technology used in XML in fact non new technology, but represent the born of SGML which have been developed in the early 80-an and have a lot of used at technical documentation of project have a big scale. When HTML developed in the year 1990, all maker XML adopt the shares most important at SGML and holded into development HTML yield the markup language which don't fail its excitement by SGML.
As does HTML, XML also use the element marked by tag is opener ( early ‘<’ and end by ‘>’), tag is close ( early ‘’) and attribute elemen (parameter expressed in tag opener for example < form name=”isidata”>). Only the difference, HTML define from early tag and attribute weared in it, while in XML we can use the tag and attribute according to we will.
Is Equal with HTML, File XML is in form of text so that when needed we can read it'n requiring special aid software. This matter facilitate the application developer using XML for the mendebug of its program. XML more fleksible compared to HTML in the case of its ability [for save the information and data. At XML we can do save the data in attribute and also as element content placed among tag of opener and tag closing.
Other excess owned by the XML is that can subsitution information from one system to other system with different platform. For example from Windows to Unix, or from PC to Machintosh even from internet to handphone with technologically WAP.

SIG with XML 1
Such as those which have been explained in article about GIS previously, explained GIS represent a system which can assist to give the clearer picture about information from a place. XML representing continuation Ianguage from HTML applicable to make the SIG. Now what such XML?
XML ( eXtensible Markup Language) is Ianguage markup providing limber sintaks ( can be developed according to requirement) and independent ( not depended by platform system). Become according to for the medium of data transfer usher various system manner, good pass the other;dissimilar internet band. XML representing furthermore development from format HTML used in World Wide Web. XML own a number of excess compared to HTML, among other things document more structure, enabling manipulation of data appearance without having to relate to the webserver, and also data transfer usher the document. Because excess XML which can conduct the transfer usher the document, this matter make the make-up of use SIG.
XML enable to load the goodness of co-ordinate data, data which figured and instruction expressing treatment type to the data. That treatment can be in the form of the transformasi data to dissimilar form and or to express how data presented.
Use XML enable the applying of internet SIG in the form of barer, immeasurable and cheap but remain to kompatibel. The mentioned can be realized by some subset of XML, that is SVG, XSL And GML to be studied at article hereinafter.

Virus Computer 2
After we know what such with the virus and also history, now we have to know the virus type. Virus can be classified to become six faction:
1) Macro Virus
Writed by using macro Ianguage pemrograman [which is made moderate, and infection of application of Microsoft Office, like Word and Excel, and in this time estimated by 75 percentage of this virus type have been gone the round of world. A document which infection by macro virus in general comand modification which will there have and a lot of used ( like comand " Save") to trigger the spreading of the comand moment x'self run.
Example:
=> variant W97M, misal W97M.Panther
long 1234 bytes,
=> WM.Twno.A;TW
long 41984 bytes,
2) Virus of Boot Sector
Virus Boot sector have common once disseminate. This virus in duplicating x'self will remove or replace the original boot sector with the program of booting virus. So that moment happened by the booting hence virus will load to memory and hereinafter virus will have the ability control the hardware standar(ex::monitor, etc) and from this memory also virus will disseminate all the existing drive and incircuit to computer ( ex: floopy, drive [of] besides the drive c). virus Boot-Sector Include the x'self into boot - sector -- a area of hard drive ( or other disk type) to be accessed first time moment PC flamed. Virus of this type of can hinder Our PC to conduct the booting from hard disk.
Example:
=> varian virus wyx , example: wyx.C(B) infection of boot record and floopy.
long 520 bytes,
3) Stealth Virus
This virus will master the tables of tables interupt at PACK which often we recognize by " Interrupt interceptor". this virus capable to control the instruction of instruction of level PACK and usually occult them by name nya either through full and or its size measure . Stealth Virus always hide out its by making file which visible infection [do] not infection, but virus of this type of seldom able to face the newest scanner antivirus.
Example:
=> Yankee.XPEH.4928. Infection file *.COM dan *.EXE
long 4298 bytes
4) Polymorphic Virus
This virus designed to make to deceive the program antivirus, its meaning this virus always try in order not to be recognized by antivirus by always fox change its structure each time finish the file infection / program other;dissimilar. Polymorphic will alter the code of moment x'self overcome at different machine; theoretically virus this type of harder to can be detected by scanner antivirus, but in in reality virus of this type is not writed better, so that easy to in order to be known its existence virus Will alter the code of moment x'self overcome at different machine; theoretically virus this type of harder to can be detected by scanner antivirus, but in in reality virus of this type of not writed better, so that easy to in order to be known its existence.
Example:
=> Necropolis A/B, Infection file *.COM dan *.EXE
long 1963 bytes.
5) Virus File/Program
This virus infection of file file which can be executed direct the than operating system, good that file application (*. EXE), and also *. COm usually also result of infection from this virus knowable by changing size measure of file attacked. This virus do to execute to propagate the x'self at related/relevant document and application with of file moment which infection opened or run.
6) Or multipartite virus represent the merger from Virus of Boot sector and file Virus: its meaning work conducted cause two, that is he/she infection can file *. EXE as well as infection of Boot Sector. good Multi Partition Infection virus file and boot-sector--sebuah of criminal of have mask to our system infection which can continuously before be under arrest by scanner antivirus.

Format MP4
Standard format for the MPEG-4 OF named MP4. Sometimes this cause the people confuse and assume as audio format like MP3. In fact related/relevant MP3 by MPEG-1. MP3 represent part of audio from original standard MPEG.
Format MPEG-4 xself in fact represent the type is so-called " container format". Its meaning this format join some different konten into one file. Usually konten joined is audio with the video, but sometimes konten like picture kept quiet also included into a file MP4.
Konten of Video and audio which merged into by MP4 can be consisted of immeasurable format. For the video of format used for example Divx, Xvid, ffmpeg, H.264 ( MPEG-4 AVC). Format of Audio of the example of AAC and MP3, while for the picture of kept quiet us can use the JPEG and PNG. All the format konten [is] inclusive of standard MPEG-4.
Besides format included in standard MPEG-4, file MP4 also can load the format nonstandar, like Ogg Vorbis and AMR for the audio of, and Ogg Theora for the video of.
Because immeasurable this family MP4, if You get the file of berekstensi MP4 from others ( for example from Internet) the file not yet visible of course [at] Your ponsel, though camera ponsel xself yield the file of have format to 4 MP4.
Though MP4 represent the ekstensi standard used for the file of MPEG-4, sometimes we find the ekstensi file of[is other;dissimilar. example this Ekstensi nonstandar for example M4V and M4A. Each representing format of video and separate audio format introduced by Apple. Music sold Apple pass the service of online iTunes use the format M4P, representing MP4 additionally protection DRM ( Digital Rights Management)

History Of Internet 1
Internet early from creating of technology of computer network about year 1960. What is computer network ? Computer network is some computer incircuit one another by hence cable in one location, for example in one office or building. This Computer network function is costumer can ti change over information and dat with another computer.
Early network Internet which we recognize this time is first time developed at year 1969 by Department Defender of United States by the name of ARPANET ( US Defense Advanced Research Projects Agency). ARPANET develop with the target to make a computer network which is gone the round of to avoid the information concentration in one dot which looked into a gristle to be broken in the event of war. In this way expected if one part of network broken, hence band which is passing the network can be automatically Carried over a other channel.
In early 1980, ARPANET broken to become two network, that is ARPANET and Milnet ( a military network), however both having link so that communications usher the network remain to can be done. In the begining this network interkoneksi is referred by DARPA Internet, but in process of time conceived of just say Internet. After, internet put into use for the sake of academic By connecting some college, each UCLA, University Of California at Santa Barbara, University Of Utah, and Stanford Research Institute. This caught up openedly of service of conducive Usenet and Bitnet of internet accessed by through personal computer (PC). Next, protocol of standard TCP / ip start introduced in the year 1982, caught up with the use of system DNS ( Domain Name Service) at 1984.
