GENERATION COMPUTER BEFORE AND AFTER YEAR 1940

GENERATION COMPUTER BEFORE YEAR 1940

ABACUS

FIGURE 1.1 ABACUS

COMES AROUND 5000 YEARS AGO IN ASIA SMALL AND STILL USED IN SOME

PLACE UNTIL NOW , BE CONSIDERED AS EARLY EARLY COMPUTING MACHINERY . THIS TOOL

Allows users to perform CALCULATION USING THE GRAIN

SHEAR ON THE SUBJECT OF A RAK . THE MERCHANTS IN THE FUTURE THAT USE

ABACUS COUNTING FOR TRADE . WITH THE EMERGENCE OF A PENCIL

AND PAPER , ESPECIALLY IN EUROPE , ABACUS lost its popularity .

Numerical wheel calculator ( Numerical Wheel Calculator )

AFTER ALMOST 12 CENTURY , THE OTHER DISCOVERY COMES IN THE EVENT OF COMPUTING MACHINERY . ON

YEAR 1642, BLAISE PASCAL ( 1623-1662 ) , who at that time was 18 years old ,

FIND WHAT YOU CALL HIM AS A numerical wheel calculator ( Numerical WHEEL

CALCULATOR ) FATHER TO HELP MAKE TAX CALCULATIONS .

FIGURE 1.2 numerical wheel calculator

SQUARE SQUARE BRASS that called Pascaline , USING EIGHT WHEELS

Serrated PLAY FOR UP TO EIGHT DIGIT NUMBERS summing . THIS TOOL

Is a calculator tool BASE TEN . THIS TOOL IS WEAKNESS

ONLY LIMITED TO ADDITIVE .

3 . Numerical wheel calculator 2

IN 1694, AN German mathematician and philosopher , Wilhelm VON Gottfred

Leibniz (1646-1716) improved the Pascaline BY MAKING MACHINE THAT CAN

MULTIPLYING . Just like its predecessor , MECHANICAL TOOL WORK WITH THIS

USING THE WHEELS - WHEELS serrations . LEARNING WITH NOTES AND SNAPSHOTS

MADE BY PASCAL , Leibniz can refine the tools .

4 . MECHANICAL CALCULATOR

THOMAS CHARLES XAVIER DE COLMAR FIND THE MACHINES CAN DO THE FOUR FUNCTIONS basic arithmetic . MECHANICAL CALCULATOR COLMAR , arithometer, presenting MORE PRACTICAL APPROACH IN THE CALCULATION OF SUCH DEVICES CAN DO BECAUSE addition, subtraction , multiplication, and division . With his ability , arithometer widely used until World War I. TOGETHER WITH PASCAL and Leibniz , COLMAR HELP BUILD mechanical computing era .

COMPUTER GENERATION AFTER YEAR 1940

FIRST GENERATION : 1944 - 1959

Vacuum tube as a signal amplifier , is a hallmark of the first generation .

IN THE BEGINNING , vacuum tubes ( VACUM - TUBE ) AMPLIFIER COMPONENTS USED AS A SIGNAL .

IN 1946 , THE ELECTRONIC COMPUTER FIRST IN THE WORLD ENDS MADE namely ENIAC . CONTAINED 18,800 vacuum tubes and large in size SO , TO - TO REQUIRE AN INDOOR class of its own .

ENIAC ( Electronic Numerical Integrator And Calculator ) , WHICH IS THE FIRST ELECTRONIC COMPUTER IN THE WORLD HAVE D weighing 30 TON WEIGHT , LENGTH 30 M 2.4 M AND HIGH POWER AND NEED 174 kilowatts .

FIGURE 1.3 ENIAC

Computer EDVAC (Electronic Discrete Variable Automatic Computer )

USE OF VACUUM TUBES ALSO BEEN REDUCED IN THE DESIGN OF COMPUTER EDVAC (Electronic Discrete Variable Automatic Computer ) CALCULATION PROCESS IN WHICH TO BE FASTER THAN ENIAC .

FIGURE 1.4 EDVAC

COMPUTER EDSAC (Electronic Delay Storage Automatic Calculator )

INTRODUCING THE USE OF MERCURY COMPUTER EDSAC ( Mercury ) THE TUBES TO STORE DATA .

FIGURE 1.5 EDSAC

1 COMPUTER UNIVAC ( Universal Automatic Calculator )

IN 1951 Dr. Mauchly and Eckert UNIVAC 1 CREATE A FIRST COMPUTER DATA PROCESSING USED FOR TRADE .

FIGURE 1.6 UNIVAC 1

SECOND GENERATION : 1960 - 1964

TRANSISTOR IS TYPICAL CHARACTERISTICS SECOND GENERATION COMPUTER . Raw material CONSIST OF 3 LAYERS NAMELY : " BASIC " , " COLLECTOR " AND " emmiter " .

COMPUTER - COMPUTER THIS IS THE SECOND GENERATION USING COMPUTER FULLY TRANSISTOR . THEY ALSO HAVE COMPONENTS can be associated with COMPUTER AT THIS TIME : PRINTER , storage, disk , MEMORY , OPERATING SYSTEM AND PROGRAM .

SOME PROGRAMMING LANGUAGE THEN start popping . PROGRAMMING LANGUAGE -ORIENTED BUSINESS COMMON LANGUAGE ( COBOL ) AND FORTRAN (Formula Translator ) came into common use . REPLACE THIS CODE PROGRAMMING LANGUAGE MACHINE WITH COMPLICATED WORDS , SENTENCES AND MORE MATH FORMULA easily understood by humans . This makes it easier for someone to program a computer . VARIOUS NEW CAREER (programmer , COMPUTER SYSTEMS ANALYST AND EXPERT ) . SOFTWARE INDUSTRY also began to emerge GROWING ON THE COMPUTER AND SECOND GENERATION .

SECOND GENERATION COMPUTER IMAGE 1.7

THIRD GENERATION : 1964 - 1975

THE SMALL AND THE CONCEPT OF TRANSISTOR LOW .

FINALLY WORKED THOUSANDS TRANSISTOR COMBINED IN ONE FORM A VERY SMALL .

A piece of silicium WHICH HAS WORKED IN SIZE few millimeters CREATE AND THIS IS CALLED AS INTEGRATED CIRCUIT OR IC - CHIP that are characteristic THIRD GENERATION COMPUTER .

FOURTH GENERATION : 1975 - NOW

CHIRI MICROPROCESSOR IS TYPICAL FOURTH GENERATION D COMPUTERS ARE THOUSANDS OF COMPACTION INTO AN IC CHIP .

IN 1971 , DEVELOPING INTEL CORP FIRST SERIE MICROPROCESSOR 4004 .

FOURTH GENERATION COMPUTER IMAGE 1.8

FIFTH GENERATION : THE FUTURE
