Such as those which written in article of What Is Computer 1, there are three division software that is operating system itself, application user, and last of device driver. This opportunity, I will a littel studying about device driver, in a word device driver is channel of place software communicate with hardware.
Simply device driver is same as other application, although with a few very important difference. First, device driver not use the window and icon to communicate with the user, but there is among program which You use and hardware itself. Ordinary application will not men-crash of overall of system if there are bug, but device driver have to be writed by cleanness and dites so that can work properly.
In a lot of matter of device driver loo like by Dynamic [is] Link Library or file DLL used by Windows and each;every program for the save of part of code which often used. When device driver walk, he give the information ( so-called object driver) to Windows hit to which hardware the communicate and what can do of.
Follow the example of the communications device that is when You wish to print the document or incircuit to Internet, Windows will check the Function Dispatch Table to see the such as code which can do the the request. After finishing, Windows later;then will give the the request to pertinent device driver so that executed, so that Your printer make a move and Your modem turn around the number ISP.

ASP (Active Server Page)
Have all of you see a dynamic web? One of dynamic characteristic web in the web can present the date of and appropriate time. The example, if a web present the date of today, for example 7 March 2008 and when tomorrow the date of turning into 8 March 2008 hence the web is inclusive of dynamic web. What will be way of to make a web become dynamic? Whether need a software to make the dynamic web? Read and find its answer by bringing article hereunder.
One of way of to make the dynamic web by using ASP ( Active Server Page). ASP environmental laboring script program of website and internet, ASP also represent the appliance ( software) implementation from middleware although in practice nya represent the part of web server [of] like PWS ( Personal Web Server) or IIS ( Internet Information Service) commisioned translate the on file script in binding by file .asp. This Skript-skript extend the ability HTML so that can be obtained dynamic web.
ASP represent the software made in microsoft which is officially launched at date of 16 July 1996 by the name of code Denali. Beta Version ( to know the bugs any kind of which is there are) ASP launched at november 1996. While for the ASP OF Version 1.0 launched at date of 12 December 1996.
ASP Work by: Client beginning ask an script ASP and give the kemesin ASP. Hereinafter machine ASP translate it become the code HTML. By web server, result of from this machine ASP sent to client.
To make the dynamic web by xself, ASP have jointing to database. To communicate with a database, script ASP need the ODBC ( Open of Database Connectivity) and ADO ( Activex of Data Objects).
ODBC ( Open of Database Connectivity) is a standard addressed for the make of communications between a application with any database. Of course, in its implementation each;every database own the functioning ODBC driver by xself conduct various translating so that can be comprehended by application accessing database. ADO ( Activex of Data Objects) comprising a number of object which can be weared by application to communicate with the ODBC. ADO also developed by Microsoft.

Email Or electronic mail is a service of letter delivery but do not like letter squired a post father, message delivered by passing enamel do not only comprise the article or text of but also can comprise the good data in the form of picture, voice, video and others. Others, email delivery nor need the old need time like we deliver the letter pass the post of fice of but only with the time of some just just second message which we send have legible process one who we send order.
Besides speed of letter delivery which quickly, email also own the excess is so-called mailing list, that is we can send a same message for a few email address in one time only by delivering the message to a email address which is the inclusive of into mailing list of the example xxxx@yahoogrops.com. Constructively this filtur is we needn't be busy deliver the same message to one by one email address.
Slowe but surely, email have come to the indivisible shares from all day long Indonesia society. Data from Asosiasi Penyedia Jasa Internet Indonesia ( APJII) indicate that in the year 2004 ago, sum up the costumer Internet in Indonesia reach 1.087.428. While wearer Internet xself as much 11.226.143. This matter show the growth from next years., inappropriate though goals APJII as much 12 million wearer in the year 2004.
Fast Email usage also peeped at by provider phone to grasp to equip the its handphone brand inserted by filture email delivery by using network WAP, GPRS, and also 3G. the example of Service of push e-mail represent the konvergensi from service of e-mail and conducive mobile system relaying e-mail to ponsel or PDA phone. By push e-mail, owner account can accept or deliver the enamel, non again in the form of SMS, passing terminal in the form of ponsel or PDA. Push E-Mail exploit the koneksi ponsel or PDA phone to network GPRS ( Global Packet of Radio System) or PDN ( Packet of Data Network). Simply, push e-mail xself can be conceived of mirror or mirroring of e-mail desktop presented in ponsel.
But, not all consumer ponsel can exploit this service. Only ponsel of type smartphone being based on Symbian ( S60 And UIQ) and PDA Phone base on the just Windows Mobile 2003 which can enjoy . This matter caused by caused by its software which must diinstal of ponsel. Besides software, something else which require to be made available by operator of service of push of itself e-mail.

Computer Virus 1
In this time, computer virus have assorted of type and its for, what before now only groan the file of microsoft word but now virus open fire the application windows. When we do cleanig with anti virus, sometimes file is virus infection also follow vanished, causing the data become to destroy. Multiply its virus of a computer also will make the computer performance of a few/little slower because some virus there groaning precisely system work a operating system. But, there is also some virus which only follow the life at a computer, this matter because of the virus do not influence the performance of computer of place in multiplying.
Computer virus xself defined as A program the that can infect other programs by modifying them to include a slighty altered copy the of itself.A of virus of can spread throughout a computer system or network using the authorization of every user using it to infect their programs. Every Programs that gets infected can also act of ace of a of virus of that infection grows.
usage of virus Word first time is used by Fred Cohen in the year 1984 in United States, this matter because of disease ( virus) at computer own some elementary equation virus in the field of doctor. Computer virus xself can be interpreted by as a infection program which can program the other;dissimilar. Program which infection have by virus can cause the happening of data manipulation even make the the program become to destroy the. Virus will multiply when when program which infection have by an virus executed or run.
In year 1960, all expert in Lab BELL ( AT&T) try the virus theory which laid open By John Von Neuman become a game. All the expert make a program which can multiply the x'self and break the program from opponent play the nya. Program capable to hold out the kan conceived of by a winner. Game make the program which can multiply this x'self become the game favorite almost all lab computer. This matter result the programs made become to more and more dangerous.
Newly in the year 1980, the program is which recognized by the name of " virus" this succeed to disseminate outside laboratory environment, and start to circulate [in] world cyber.

TCP/IP ( Trasmission Contro Protokol/ Internet Protocol )
World Internet have become the part of modern life style, but know all of you how computer network earn incircuit with the network internet? Following a little solution of about how a computer earn is communicating with each other other computer.
TCP/IP ( Trasmission Contro Protocol/ Internet Protocol ) is a group of a group of protocol arranging communications of data of computer diinternet, can be told also TCP / IP is a set of standard protocol used to connect the network of computer and traffic address in network. This protocol arrange the permitted data format, mistake handling ( error handling), traffic ordered, and other communications standard. Protocol by xself mean a set order arranging precisely is communications format usher the system. For example, protocol HTTP arrange the communications format of between browser web and browser server. Protocol IMAP arrange the communications format of between server of email IMAP with client.
With the existence of TCP/IP computer remain to earn is communicating each other even there are hardware difference and also used operating system, for example computer which have operating system to of Windows remain to can communicate with the computer using operating system Macinthos.
Protocol xself own the marking for example:
a) TCP / IP developed to use the open protocol standard.
b) Standard of protocol TCP / IP in the form of Request For Comments ( RTC) can be taken by whoever without expense.
c) TCP / ip developed with do not base on the operating system/ certain hardware. And still a lot of the other marking.
Internet can be formed by because a group of big computer network own the agreement for the < i> To converse in same Ianguage. This agreement solely represent the agreement having the character of technical for lack of one organization in this world rightful claimant arrange the way internet.
Though TCP/IP developed with the open protocol standard, but immanent [of] body in charge of in arranging, controlling, and also do the standarisasi protocol used in Internet. As for the organization's is:
a) Internet Society ( ISOC), professional organitation which facility, supporting and also promote the growth internet, as infrastructure global communications to research into and research.
b) Internet Architecture Board ( IAB) is organization co-ordinate and technical adviser for ISOC. This Body act as the body review and editorial all standard internet. IAB own the authority to publish the document of standard internet recognized by Request For Comments ( RTC).
c) Internet Engineering Task Force ( IETF) is organization orienting for the standard form of internet. To arrange the job IETF hence physique is so-called Internet Engineering Groups ( IECG)
d) Internet Research Task Force ( IRTF) this organization have orientation at researching into in the long term.

STRUCTURE of DECODER VIDEO MPEG-4
Decoder of Video of MPEG-4 of personating of input of data stream, regular consecution of beet deputizing consecution draw the presented video. Data stream load the information lapped over consecution structure draw the video, what is good match for MPEG-4 of Video of International Standard 14496-2. Data stream start to explain part of video, representing part of video picture which is formed of one or more syntax structure identifying video object. Video object deputize a object contained in consecution draw the video and can be joined to become one or more coat of video object. coat of video Object represent a syntax structure identifying its own data stream and permit to get the consecution which can scale. peripheral of video Object is structure hereinafter identifying incidence single video object when shortening.A Video of Object Plane ( VOP) made of some macro block, each;every macro block builded by 8 x 8 block luminan, krominan and often also clearness of values piksel.
Stream of input Data load the information about tekstur, move, and structure each;every VOP Form the information identify the object which is taken a short cut in VOP. Information move to lessen the time-wasting whereas consecution draw the video, connecting macro block from VOP which now with the macro block develop;builded previously. Tekstur of Information didecodekan by using a algorithm lessening space extravagance.
Process the decode tekstur got first time apply all Algorithm Very Length Decoding ( VLD) explaining code word from tables Huffman. Later;Then inversi of algorithm scan rebuild the block 8 x 8 from coefficient array which quantization. After inversi of algorithm of prediksi AC & DC And inversi of quantization algorithm, a Inverse Discrete Cosine Transform ( IDCT) applied in block 8 x 8. In course of decode tekstur depicted [by] that more intensive operation computing VLD and IDCT. Decoder which is outlined in under show how big biayan operate for the VLD and IDCT for the time of decode.
Compensation algorithm move process decode of other;dissimilar costly. This algorithm rebuild each;every macro block begining from coresponding macro block to VOP rebuilt previously. If this coresponding macro block unegual ( in certain sill) with the macro block which now, a[n estimate of information of error diekstraksi from stream of data and didecode by using algorithm of decode tekstur. In this case macro block which now got as quantifying from macro block ( coresponding) with the macro block rebuilt wrong mendecode prediksi.
To identify the most expected module, have been shown implementation of software of decoder of video MPEG-4. Examination Consecution used have the long foursquare and single coat VOP ( VOP contain the foursquare object length, form without information). examination Decoder have been conducted at Pentium II 266 MHZ, to know the insuffiency of process VLIW. Have been estimated previously that computing time at Pentium II proporsional to computing time of VLIW.

PHP (PHP Hypertext Preprocessor)
PHP ( PHP Hypertext Preprocessor) is debate which is the in form of script placed in server and processed in server. Result from php will be sent to client in place wearer of menggunkan browser. PHP often used to make the dynamic web, its meaning can form a[n appearance pursuant to request nowadays. Can be told also PHP is Ianguage of server-side scripting which is one by HTML to make the dynamic web. Server-Side Scripting sintaks and comands given will be run by full diserver but figured in document HTML .
PHP emerge first time in the year 1994 namely moment of Rasmus Lerdorf make a number of skript Perl which can perceive the whosoever which look around its curriculum vitae. The Skripts tidy to hereinafter become the tool is so-called " Personal Home Page." New in the year 1995, moment Rasmus create the PHP / fi 2 which can paste up the structure code ( urut) in tag HTML.
PHP have the character of the free or free wear ( not like ASP representing original product Microsoft) You download php in www.php.net for the version of windows. PHP also can be develop by as module of web server Apache and for binary which can walk for CGI.
Principle work the PHP is when binding PHP asked to be got by web server, its contents immediately sent by this kemesin PHP machine and of mamproses and give its result in the form of code HTML to later web server submitted/sent to client. Thereby a consumer internet cannot see the program code which is written in by PHP so that security from web become more well guaranted.
Because script PHP have to be sent first to machine PHP there are some badge differentiating script PHP by HTML, that is:
1. <? php
Your Php code
? >
2. <?
Your Php code
? >
3. < script language="PHP" ? >
Your Php code
</script>
4. < %
Your Php code
%>
Excess from PHP can deliver the HTTP header doormat can cookies arrange the authetication and redirect user. Others, PHP also can communicate with the database. So that data served can have the character of dynamic. Some database which can communicate with the PHP is dBase, DBM, Mysql, Oracle, and others. PHP also can integrate with a few library eksternal which can make the You can conduct the making of document PDF till memprase XML. PHP also support the communications with the other service through protocol IMAP, SHMP, POP3, or HTTP.
