EXPLOITING of COMPUTER IN PUBLIC

11 ANTECEDENTS

Without we realize, computer has stood in public. This thing applies in developed countries and also in state is being growing in Indonesia. Computer actually doesn't differ from other tekhnologi product like train, plane, television car and others. What differentiating computer with other product be the ability to be able to be program to execute assorted of duty with high speed and correctness.

The physics experts, electronics and computer has developed microprocessor which big is capable. Such processor many applied as part of controller of other energy product like guided missile, motor vehicle, aeroplane, camera, personal computer and this thing always grows as according to development of epoch.

Computer at the moment many applied as a means of assists to process various data types like processing of student value with computer, making of value list, calculation average of class nor reports for kepentinag evaluation of education. Computer also have been many applied to print electrical invoice receipt, telephone, credit card and others.

Basically computer is applied as a means of assists menyimpan to, process and takes again data or information required. Work area that is also starts affecting as seen exemplified following :

" Preparation of correspondences up to storage of archive is office.

" Filming in the field of animation and effects 3 dimension

" Seeking of book based on book heading and author's name in library

" Administrative services and quality of medical service at hospital.

" Ordering of ticket peswat flies at perusahan international and also domestic air transport.

" administration of State like data administration of officer, data administration kependudukan, making of KTP, SIM and others.

" Usage of computer in the field of industry.

Some examples is upper is a few example of exploitings of computer in various work areas. Still many other areas which has not been mentioned. Appreciation to impact of a new product not always must have of circumstantial knowledge about the product. Observation to impact of computer is public able to be done by exploiting tekhnologi is around [by] public.

12 Some The Application Of Important

Computer is a real basic and important invention. Computer is not only assists works however changing mode of action and at the same time generates new challenge and problems in area.

1.2.1 Clever Cars

Microprocessor dimanfaatkat has to increase comfort and safety pilots car. For example in the year 1985, oldsmobile from US has applied control system to base on microprocessor at its(the product. Microprocessor gets data input from some sources, like :

" Metre injection pump ( machine burden)

" Alternator ( rotation mesin/menit)

" Machine cooling system

" Absolute pressure sensor to watch circulation and pembuanagan gas

" Transmission tooth

The input data diolah by microprocessor to perform [a] precaution that machine is not too temperature, watchs rotation of machine, machine burden and usage of correct transmission tooth and as according to requirement.

1.2.2 Electronic libraries

Space and time was two main problemses faced by Perpustakaan these days. Cost needed to by menyimpan book, magazine, journal, newspaper and handing out always swells. Beside the matter, library officer burden to serve reader to find reading material required increasingly day increasingly heavy because reading amounts that is increasingly increases. This thing results slow of service.

The problems is tried overcome with help of computer. Computer at this sat have been can replace powered katalogdan accomodated big. Data base system jugatelah grows so that able to manage data in jumlha which very big. Progress in tekhnik re- seeking is information had enabled done seeking to return inside information of a flash in the pan.

Development of tekhnik printing with help of computer membuaka new nuance in moth-balls information. Book or magazine printed always diolah and crosschecked with computer, so that information of obtainable elektronis directly.

1.2.3 Operations of Air Traffic

Air traffic was traffic that is very gristle in human life, although in indonesia number of its(the air transports still be relative low compared to advance nations. Even though operation of air traffic have been executed modernly, done with sophisticated equipments bases on computer. This thing is done by defaults in operation of air traffic will cause on fatal.

1.2.4 Weather Data Processings

Weather data collected from hundreds or even thousands of station of station of watcher in bumidan is space. This data channelled through international telecommunications channel to center weather data processing. To form model peraamalan of local weather.

1.2.5 Video Games

This game very quickly gets marketing and particularly in liking by the rising generation. Various game types which have never is realized to become reality. Place of game spread over dimana-mana in center expenditures, recreation or in nearly school. So young children started forgets its(the obligation as pupil or as member of public. The this game supporters express that game character is educate and increases coordination between eyes and hand. There is whereas pendapay telling that youngster taking a fancy to permaianan of video they will interest with computer and programmer however more personal computer in reality applied for game from at programmer.

Recognition of Internet

11 Internet Understanding

Internet is gathering of related personal computer one otherly in the form of network. Network is created [by] through telecommunications channel, like telephone. Personal computer can reside in various places that is separate, either in international and also national region.

Every personal computer merged into by network can communicate in the form of transfer of lateral data of image and voice. In a second and in two directions. Other term for internet is virtual world, cyberspace,homepage ata www ( world wide web)

Internet is property of world public. Nobody or institute which can claim Internet as property of his own. As member of internet, you can do transfer of text and various messages with having million man in business, academy, other goverment and organization, access software, documents about art, politics, culture, picture, map, weather, library catalogue and various information from various place of whole world.

Internet supposed as an fairish electronic town of giant, where every resident has address which applicable to send letter. If we like to circled enough town with its(the computer as vehicle.

Operation of convergent network to supporting facilities for telekominikasi. Its(the low-speed line using modem and telephone channel; while its(the throughway using ISDN or frame relay.

12 Development of Internet

Internet has created new world for human life. Which its(the apparition is started started [by] when department of defence of United States makes project of ARPA ( Advanced Research Project Agency) with the title ARPAnet. ARPANET semuala designed to find reliable computer network, and smpai how big movable information and all standards determined to become genesis for expansion of new protocol recognized as TCP\IP.

Then NSF ( National Science Foundation) continuing this project and then creates network x'self so called NSFnet based on technology IP used by ARPAnet with telephone channel as supporting facilities for transmission. Because its(the cost is too height, hence the side of NSF decides makes alternative where computer will relate to local network, then this local network distributes to other computer network.

This success alternative, so that its(the computer network is developed furthermore by Merit Network Inc to cooperate with IBM and MCI, however relationship still limited to academy area, governmental research institute and institution in United States.

13 Internet Facility

Internet as global computer network has proven can water down its(the user to communicate and memeperoleh information. Following is enclosed facilitys owned by internet, inter alia :

" E-mail

" Mailing List ( newsgroup)

" File server/transfer

" Web/Distributed Multimedia database, as plane

" Video and Suara

Electronic mail ( E-mail), By using this facility you can send letter and file between computers keseluruh world only pay [for] modulation of local telephone and news which you sends to until purpose in a few minute.

Newsgroup ( mailinglist), This facility built with the same tekhnik with electronic spreading process. With this facility news in distributing kebanyak user at the same time, so that its(the user can do discussion, seminar, delivered a lecture, had conference in electronic without engagement by time and space.
