Irc or Internet Relay Chat is one of the very application enthuse by all circle, slimmest but one who know the history irc. hmmmmmmmmm..... well we will study a little about irc, what I take from...
IRC ( Internet Relay Chat) in making by Jarkko Oikarinen of at year summer 1988. He make the IRC client and IRC server in University Oulu, Finlandia (At the time of he work in Department of Science Information). Jarkko taken an interest in by software BBS which he use in toslun.oulu.fi , to give the news to network consumer, direct discussion and some other function. First implementation is shares chat, what he borrow from its friend is Jyrki Kuoppala and Jukka Pihl . That first time in test in a that first and server machine is so called of tolsun.oulo.fi
IRC in making to replace a ordinary program in mentioning “ talc . IRC is multi-user chat system of related to server in all the world. We later can join to a room chat or ordinary in mentioning channel . That is a room virtual for the meeting of all consumer IRC
Internet Relay Chat is later completed at the (time) of desert war in year 1991. Between this period, information accepted to channel to the whole world. A family can communicate with the distance of thousands of mile. IRC is a just meeting place to whom requiring direct information of up to date and reliably
Usefulness IRC very assisting at the (time) of riot of Kiosk Angeles, moment of bombardment Israel, president election in United States, as well as location of Monica Lewlinsky. Network of IRC BBS more and more trusted in liberty of speech.
Need remember in considering that Internet Relay Chat is free of charge and do not defray by big company, but by small group is which among others is Sysops ( System Operators ), Admins ( Server Administrator ), and IRCOPS ( IRC Operators ). This People is not paid for the activity of their and will be continued to provide the peaceful environment to we are, as consumer IRC
At this shares is I am only explaining marginally concerning and pascal of tips writing of program. We start, ok? How Pascal program structure? Pascal consist...
...of 2 bodywork, that is variable declaration and his program. Paying attention example of :
1: my Program Me;
2: crt uses;
3: var is name of: string;
4: Begin
5: isn't it the name of you '); readln(nama);
6: clrscr; 7: write('Hi ', name of, ' apakabar?');
8: End.
Don'T thing of that program content. But pay attention his structure. At line to 3, that the so-called variable declaration shares. While from line fourth until 8, referred as part of statement ( place of write program). that First line only is his program title, do not in writing also may. Title of is " My me", don't isn't it the space of him ( use line under ).
In Pascal there is so-called other units a kind of library.. For example at used by both line of crt uses; ( functioning for the manipulation of text screen). Paying attention line 6, that is one of the function of unit of crt that is to clean screen ( is same by order of cls in PACK). Paying attention the way of writing of his program! Every line is always terminated with comma dot ";" ( except to of line fourth and 8, in consequence is sign from early and final of program). Besides pascal program is always started by " begin" and " end." ( don't forget his dot).
How, easy to is not? I is love one tips which good for. if write program labour the nattyness. Remember if (there are) any " Begin" sure exist " end", so writing of program among and begin of end that labour in love 2 space or one tab. Paying attention line of ke-5 until 7. That will facilitate searched of program when happened mistake. Recognition of enough until here. Ok !!!... : P.
UNIX started by moment a research group of AT&T Bell Laboratories, General Electric and of Massachusetts Institue Of Technology, cooperate below/under project of MULTICS ( Multiplexed Information Computing System) year 1968. Two people researcher of so called AT&T Bell Laboratories of Ken Thompson and of Dennis Ritchie develop UNIX together with all other researchers under project of MULTICS this. UNIX meant...
...to become operation system which is and multiuser of multitasking and to fulfill desire of UNIX rewritten in the year 1973 using Ianguage of C ( UNIX is first time written to use Ianguage of B ). This enable UNIX to be able to in re- develop to various platform of hardware without having to write down specific code to every platform. Amenity of this develop still stay hitherto so that variant - variant of UNIX available of PC until Super Computer .
Along growth of UNIX, Bell isn't it system operate for this formal in institutions and education, of him to Computer Science department of University of Berkeley California, finally yield some cloning of UNIX it selves with code of BSD ( Berkeley Software Distribution). Development of this distribution is supported full of by DARPA ( Defense Advanced Research Projects Agency), including super protocol of excitement of TCP / IP becoming soul of Internet the popularness now. But this started appearance all kinds of type of UNIX, hence to solve problem this Institute Electrical Engineers of ( IEEE) develop standard of ANSI ( American National Standards Institute) new is so called as standard of POSIX ( Portable Operating System Interface Computer Environments for). This Standard define how system operating like UNIX / UNIX clone operated, this standard also arrange in detail usage of kernel calls (rutin system) and system interface. Standard of ANSI become billows is problem oves compatibility and assist development of further UNIX.
More and more distribution him of system like UNIX happened, and with all excess had by system it self, however one matter become clearly: UNIX developed for workstation and mini of computer. Mean all students at big University cannot use the the variant to try application of UNIX at Personal Computer ( Their PC ) in final 1980 and early 1990. Even although Professor Andrew ( Andy) Tanenbaum have created MINIX, mini variant of UNIX, that thing do not have all function of UNIX wanted by all moment students that, priority for to so called student of Linus Torvalds. And emerge of LINUX as variant of UNIX most flexible walk most of all platforms of hardware existing this time.
