development of information technology


assalamu'alaikum .. meet again with me , I want to share again , this time on the development of information technology .. do not be bored reading my article, may be useful, insya'allah .. let 's see ..Development of Information TechnologyPrehistoric periodSince prehistoric times , humans have been using and developing different forms of information and communication technologies . In prehistoric times , exactly in the stone age , man has tried to use information technology in the form of images that share the experience of hunting and animal images that catch on cave walls . At this time , humans have been able to use sound cues in the form of grunts and hand signals to communicate with each other . Then , they use tools that produce sounds and cues , such as drums , trumpet from animal horns , fire , and smoke to convey messages over long distances.

    
Pictograf letters ( 3000 BC )At this time , the Sumerians began using picture symbols are formed into letters ( pictograf ) that represent different sounds . These letters when strung together would be a word , sentence , and language .

    
Hierogliph letters ( 2900 BC )Ancient Egyptians use hierogliph letters , ie symbols that represent different expressions . Compared with the Sumerians used pictograf , hierogliph symbol is more modern .future HistoryDiscovery paper ( 105 AD ) by the Chinese to sign the development of written language and the forerunner of the current paper . At that time , the paper made ​​from bamboo fibers are crushed , filtered , washed , and then flattened and dried . With the invention of paper , printing technology emerged using wooden beams covered in ink and stamped on paper . This is similar to the seal / stamp that you know today .Modern periodSome key events associated with the development of ICT in modern times are as follows .

    
Print engine ( Year 1455 )In 1455, Johann Gutenberg created the first printing press using the plates of the earth is made of iron . The plate can be replaced in a frame made ​​of wood .

    
Anatyticat Machine ( 1830 )Charles Babbage create analytic engine capable of entering the data , process it , and cards issued in the form of output forms . By using this machine also Augusta Lady Byron for the first time to write scbuah first computer program in the world . Though still mechanical , inspired the creation of this machine digital machine a century later , the first digital computer called ENIAC I.

    
Telegraph and Morse Code ( Year 1837 )In 1837 , invented the telegraph and Morse code machine by Samuel Morse with two friends , that Sir William Cook and Sir Charles Wheatstone . They managed to transmit news through cable with Morse code ( electrical impulses ) in between the two places are far apart .

    
First films ( Year 18610Film is a communication tool to express ideas and convey a message to the crowd . The beginning of the film was created in 1861 .

    
Telephone and Photography (1977 )Based on the technology of the telegraph , in 1877 , Alexander Graham Bell invented and developed a phone that is used in general for the first time . At this time , also found high-speed photography by Edward Maybridge .

    
Magnetic Storage Pieta ( 1899)In 1899 , for the first time created in tape storage systems ( tape ) magnetic tape made ​​of strong plastic called Mylar . One side of the tape is a kind of magnetic material coated iron oxide ( iron oxide ) .

    
TV Tube ( 1923 )In 1923 , the first tube TV Zvorkyn created . At that time , has not appeared transistor technology so that electronic components are used is still a vacuum tube .

    
Storage Media Magnetic Tape ( 1940 )Commencement of the development of science in the field of information occurred during World War II . The development aims for the benefit of sending and receiving military documents that are stored in the form of magnetic tape .

    
Hypertext ( 1945 )Vannevar Bush developed a coding system using hypertext . By encoding hypertext , can be created web pages on the internet use .

    
First Digital Computer ( 1946 )In 1946 , less than a century after terciptakanya by Charles Babbage's analytical machine , invented the world's first digital computer , called ENIAC I.

    
Transistor ( 1948 )Researchers at Bell Telephone developed transistors to replace vacuum tubes that were previously used . In addition to its small , transistor requires only power source is small and does not cause significant heat .

    
Planar Transistor ( 1957 )In 1957 , developed the planar transistor electronic components by Jean Hoerni . With this technology , millions of transistors can be incorporated into a small chip of silicon crystal . In the same year, the Soviet Union ( USSR ) launched the first artificial Earth satalit , the Sputnik who served as a spy . To compensate , the United States formed the Advanced Research Projects Agency ( ARPA ), which is under the jurisdiction of the Department of Defense to develop science and technology in the field of military information .

    
Desentratisasi Computer Networks ( 1962 )Rand Paul barand of the RAND Corporation was commissioned to develop a decentralized network system capable of controlling the system of bombings and missile launches in a nuclear war .

    
Computer Networking First in the U.S. ( 1969 )The first network system formed by connecting the four points where , the University of California , SRI ( Stanford ) , University of California of Santa Barbara , and the University of Utah with a power of 50 Kbps .

    
E - mail program ( Year 1972)Ray Tomlinson created the e - mail ( sending a text message / electronic mail via the Internet ) to the first .

    
Internet (1973 - 1990)The term Internet was introduced in a paper on the TCP / IP ( Transmission Control Protocol / Internet Protocol ) . Then, the development of a networking protocol known as TCP / IP . This protocol was developed by DARPA group . In 1981 , the National Science Foundation to develop the backbone called CSNET 56 Kbps capacity for each institution in the government . Then , in 1986 IETF mengetnbangkan a server that serves as a means of coordination among DARPA , the ARPANET , DDN , and Internet Gateway .

    
1991 - PresentWorld Wide Web ( WWW ) . In 1993 , internet services were developed , including the provision of directory services , data storage , and database by company AT & T. To become a member of the Internet , provided service registration ( registration ) by Network Solutions Inc. company . and information services provided by General Atomics / CERFNET . Since then , the internet is progressing very rapidly and began to enter the various aspects of human life .
