This document summarizes the early history of counting and calculating devices, starting from ancient times when people counted on their fingers and stones, through the development of the abacus in China around 5000 BC. It then discusses the invention of calculating rods by John Napier in 1617, Blaise Pascal's development of an early mechanical calculator in 1642, and Charles Babbage's invention of the first computer in 1835. Finally, it mentions Herman Hollerith's creation of a tabulating machine in the 1880s to help count the US population.
HISTORY OF COMPUTERS
The abacus was the first calculating device, created in China over 5,000 years ago. John Napier then invented Napier's Bones to aid in multiplying large numbers. Blaise Pascal subsequently developed the Pascaline, one of the earliest mechanical calculators. In 1835, Charles Babbage built the Analytical Machine, an early general-purpose computer. Herman Hollerith then invented the tabulating machine to help count populations in censuses.
History of computer
Counting on fingers was one of the earliest ways for people to represent and communicate numbers, by displaying quantities on hands. The abacus was then developed as the first calculating machine over 5,000 years ago in China, using a wooden frame with movable beads to perform arithmetic. Later inventions included Pascal's arithmetic machine in 1642 and Babbage's analytical engine in the 1830s, both attempting to mechanize mathematical calculations, before the development of tabulating machines in the late 19th century that could count populations.

History of computers
Charles Babbage is considered the father of computers, as he invented the first mechanical computer called the Difference Engine in the early 1800s. The computer was a special purpose calculator used for navigation. Computers have since evolved through 5 generations from vacuum tubes to transistors to integrated circuits to microprocessors and now artificial intelligence. Early computers were mainly used for calculations, but later designs incorporated programs allowing computers to perform ordered tasks. IBM was a major computer manufacturer starting in the 1980s, producing notable computers through significant programming efforts for calculations and other purposes.
The history of computers
The first computers were human beings who performed complex calculations manually. The abacus was one of the earliest aids for mathematical computations. In the 1600s, inventors like Blaise Pascal and Charles Babbage began developing early mechanical calculators to reduce human error and speed up calculations. During World War 2, the U.S. military funded research into programmable electromechanical computers like the Harvard Mark I to compute ballistics firing tables faster than human computers could. The microelectronics revolution later allowed integrated circuits to replace wired components and enabled the mass production of computers.
The history of computers
The document traces the history and evolution of computers from their origins in 1936 with the Z1 to recent developments after 2000. It discusses early pioneers like John Atanasoff, Clifford Berry and IBM. Home computers emerged in the late 1970s and the IBM PC revolutionized the consumer market in 1981. Microsoft created the MS-DOS operating system that same year. The document also outlines the development of laptop/notebook computers and peripherals over time as well as some curiosities in computer history including early games and the invention of the mouse and floppy disk. Potential disadvantages like cybercrime and protecting personal information online are also briefly covered.
History of computers
Humans have performed arithmetic calculations since prehistoric times using methods like counting on fingers. The development of number systems allowed early civilizations to track astronomical cycles and business dealings, giving rise to the concept of "computing". As calculating tools advanced from manual to electronic methods, the first computers emerged. During the early stages of development, notable calculating machines included Napier's Bones for multiplication, the slide rule, Pascal's rotating wheel calculator, Babbage's Difference Engine, and Hollerith's punched card tabulating machine. These inventions marked progress toward the electronic computers of today.

History of computer
Thousands of years ago, people used bones and stones to keep accounts and perform calculations. As the need for more complex calculations grew, early calculating devices were developed, beginning with the abacus. Over many years, inventors created numerous mechanical calculating machines using new technologies and principles, including the Napier bones, slide rule, Pascaline, stepped reckoner, and Leibniz calculator. These inventions paved the way for modern computers by demonstrating how numbers could be mechanically manipulated through gears, wheels and other analog components.
History of computer
The abacus was an early calculating tool used by ancient Babylonians. In the 1600s, important early calculating devices were invented including logarithms by John Napier, which allowed multiplication via addition, and Pascal's mechanical calculator. In the 1820s, Charles Babbage proposed plans for an automatic mechanical calculator called the Difference Engine. Herman Hollerith later invented a punched card reader and mechanical counter that automated census data tabulation, laying the foundations for modern computing.

It describes early counting devices like the abacus and advances in mathematics. Key figures who contributed to early calculating machines are mentioned, such as Pascal, Leibniz, and Babbage who envisioned a programmable computer. Major milestones include the first general purpose electronic computer (ENIAC), the stored program concept with EDVAC/EDSAC, and the first commercial computer (UNIVAC I). The first generation of computers used vacuum tubes, were enormous in size, and could only solve one problem at a time.
Computer
The document summarizes the history of computers, beginning with the invention of the first mechanical calculating machine by Blaise Pascal in 1642 using wheels with teeth to represent digits. It then discusses how Charles Babbage worked on principles of modern digital computers and designed machines like the Difference Engine in the 19th century. Finally, it notes how analog computers that used rotating shafts and gears to evaluate equations were built in the early 20th century, and how the first fully electronic digital computer called Colossus was created during World War 2 in 1943 at Bletchley Park in the UK to decode encrypted German messages.

It then discusses Charles Babbage's work in the 19th century developing the principles of modern digital computers through machines like the Difference Engine. Early analog computers that used rotating shafts and gears to evaluate numerical approximations were then built in the early 20th century. Finally, during World War II, scientists created the first fully electronic digital computer called Colossus to decode encrypted German radio messages.
history computers
The Chinese developed the abacus around 5000 years ago as a portable calculating tool using wood and beads. In the 1830s, Charles Babbage proposed the Analytical Engine, a mechanical general-purpose computer that was never built. Herman Hollerith later invented the tabulating machine in 1890 to help automate the processing of data for the U.S. Census using electromechanical technology.
The History of Computers
The first computers were human "computers", predominantly women, who performed complex calculations by hand. Early mechanical aids for calculations included the abacus and Napier's Bones. The first automatic calculating machines were gear-driven, including Pascal's calculator and Leibniz's stepped reckoner. Charles Babbage designed but never completed the Difference Engine, considered the first computer. Herman Hollerith's tabulating machine used punched cards to automate census counting, leading to the founding of IBM. The Mark I, completed in 1944, was the first programmable digital computer.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
