Cuneiform Lesson 1: The Evolution and History of Information Technology: Past, Present, Future Cuneiform is a writing system that originated with the ancient Sumerians of Mesopotamia around 3500 BCE. It stands out as one of the most important cultural contributions of the Sumerians, particularly from the city of Uruk. Around 3200 BCE, Uruk played a crucial role in advancing cuneiform writing, which paved the way for the development of literature. Information technology has existed for a very long time. Essentially, as long as humans have been around, information technology has also been present  Hieroglyphs Usage declined with the rise of the Aramaic language and alphabet in the Developed in Egypt around 5,000 years 6th century BCE. ago.

Over time, papyrus was replaced by parchment, then paper, as manuscripts became more decorative and eventually transitioned to printed books. A timeline shows the evolution of the Bible's form, particularly the New Testament, over two millennia. The Codex and Early Libraries (1st Century A.D.) A codex is essentially an ancient book, consisting of one or more quires of sheets of papyrus or parchment folded together to form a group of leaves, or pages. This form of the book was not widely used in the ancient world until around the second century AD, when it slowly but steadily began to replace the traditional book form, the papyrus roll. P46 is an example of a relatively old and rare form of codex, the single-quire codex. Most codices, like modern books,  P46 originally consisted of 104 leaves, Early Libraries (1st Century A.D.) with 86 surviving today, making it a remarkably well-preserved codex compared to other New Testament Libraries in Rome (Italy) papyri, which often exist in fragmentary Library of Asinius Pollio: One of the first states. public libraries in Rome, established in While individual pages are relatively the late 1st century B.C., but remained well-preserved, typically 3 to 4 lines are important into the 1st century A.D.

The Library of Alexandria (Egypt), founded in the 4th century B.C., flourished for six centuries and was a Printing Revolution (1400 – 1800) major cultural and intellectual hub of the Hellenistic world. It reportedly held half a million papyrus scrolls, including works Gutenberg’s Printing Press (1440) by Plato, Aristotle, Homer, and other notable figures. Invented by German goldsmith Johann Gutenberg in 1448, one of the most important inventions in the history of humankind. The device made it possible for the common man, woman, and child to have access to books. It made the mass production of books possible, spreading knowledge and literacy across Europe.  Before the printing press, books were In 1556, the Venetian government hand-copied or produced using block published Notizie scritte ("Written printing, where each page was carved notices"), a monthly newsletter, which into a block of wood, making books was an early form of newspaper, but not expensive and only affordable for the for the general public. rich. Early publications like relations (England Gutenberg, cast 290 letter and symbol and France) and relaciones (Spain) blocks using metals like lead, antimony, appeared in the 15th and 16th centuries, and tin and created linseed- and soot- often printed in broadsheet format and based ink for printing on handmade featuring woodcut illustrations. paper. He adapted a wine press to print paper efficiently, testing his invention by printing a Latin book on speech-making News was often read aloud due to low in 1450. literacy rates. Gutenberg Bibles, the first books printed By 1600, the idea of using the printing in Europe and the first bibles printed in press for news spread in Germany, with history. Only 200 copies of the Bible precursors like Messrelationen (trade were made, featuring illustrations and fair reports) starting in the 1580s. vibrant colors, with only 22 original The first true newspaper was Relation copies known to exist today. aller Fuernemmen und Gutenberg's innovation included gedenckwürdigen Historien, launched in creating blocks to imitate calligraphy, Strasbourg in 1605. preserving the richness of the original By 1650, 30 German cities had active manuscripts. gazettes, and the first English-language weekly magazine, "A current of General News", was published in 1622. Antwerp became a major news hub in 17th-century Europe, linking countries like France, Britain, Germany, the Netherlands, Italy, Spain, and Portugal. Governments in France and England began printing official newsletters after 1600. Newspapers and Mass Media (1600s): The rise of newspapers in the 17th century allowed for the regular distribution of news and ideas to the public. This was one of the first forms of mass media, providing timely information to a growing readership. Word of mouth was the primary source of news before the invention of the printing press, with merchants, sailors, and travelers spreading information. The Scientific Revolution and Encyclopedias Typewriters and Early Machines (1800s): (1700s) Typewriters made it easier to produce written documents quickly and accurately, while mechanical devices like punch card machines The creation of encyclopedias, like were used for early data processing in industries Diderot’s Encyclopedia, helped organize like textiles and government. knowledge systematically, laying the groundwork for future reference works and the scientific method. Diderot’s Encyclopedia was the most popular and influential encyclopedia of the 18th century. Its impact extended far beyond France, influencing intellectual movements across Europe and serving as a symbol of Enlightenment thinking. Early Computing (1900 – 1950) Denis Diderot (born October 5, 1713, Langres, France—died July 31, 1784, Paris) was a French man of letters and Analog Computers and Calculators philosopher who, from 1745 to 1772, (1900s): served as chief editor of the Encyclopedia, one of the principal works Early analog computers like ENIAC (Electronic of the Age of Enlightenment. Numerical Integrator and Computer) and mechanical calculators were developed, capable of performing complex calculations quickly. This marked the beginning of modern computing. The Telegraph and Telephone Era (1800 – 1900) World War II and Cryptography (1940s): During World War II, computers like Colossus Telegraph (1830s): were used for breaking codes and processing The invention of the telegraph by Samuel Morse encrypted information, highlighting the strategic enabled near-instantaneous long-distance value of IT in warfare and intelligence. communication. This was a major milestone in IT, shrinking the world by enabling real-time Stored-Program Concept (1940s): communication across continents. The concept of the stored-program computer, developed by John von Neumann, laid the foundation for modern computers by enabling Telephone (1876): programs and data to be stored in memory and executed as needed. Alexander Graham Bell’s invention of the telephone further advanced real-time communication by allowing people to talk directly with each other over long distances. Definition: ENIAC was the first programmable Cost and Completion: general-purpose electronic digital computer and the most powerful Completed in February 1946 at a cost calculating device at its time. of $400,000.

John von Neumann and is also known as a "Neumann computer. Decryption Process: The key letters used for encryption were essential for decrypting the messages. Mathematician Alan Turing developed a method for hand-breaking Tunny messages, which was the primary technique for months. However, hand-breaking became too slow due to the increasing volume of encrypted messages and German security enhancements. Need for Machines: It is also known as an ISA (Instruction set The demand for high-speed analytic architecture) computer and has three basic machines led to the development units: of Colossus I, built at the Post Office Research Station in Dollis Hill. Colossus I was delivered to Bletchley The Central Processing Unit (CPU) - an Park in January 1944, marking a electric circuit used for executing the significant moment in computing instruction of computer program.

The digital revolution has transformed the way we live, work and communicate. Digital Revolution (1950 – 2000) Notable positive impacts include access to vast knowledge, instant global communications, convenience, Mainframe Computers and Data innovation, and social empowerment. Processing (1950s-1960s): Key applications shaping the digital revolution today include 5G networks, Large mainframe computers like IBM’s AI, blockchain technology, IoT, and System/360 were used by governments, others. businesses, and research institutions to process vast amounts of data, marking the beginning of large-scale data management.
