The document provides an overview of the history of information and communication technology (ICT) from ancient times to the present. It discusses early forms of communication like writing systems and libraries in ancient civilizations. It then covers the mechanical age with developments like the printing press and slide rules. The electro-mechanical age saw innovations in telecommunication like the telegraph and telephone. The electronic age discusses early computers using vacuum tubes and the development of stored-program computers. It outlines the four generations of digital computing from vacuum tubes to microprocessors on a single chip.
Evolution of computer
Computer generations can be categorized into five periods:
1) First generation (1945-1955) used vacuum tubes and were very large, expensive and unreliable.
2) Second generation (1955-) replaced vacuum tubes with transistors, making computers smaller, cheaper to maintain and more powerful.
3) Third generation (1960s) used integrated circuits which further increased speed and efficiency by miniaturizing transistors onto silicon chips.
4) Fourth generation (1970s) used microprocessors on chips smaller than a postage stamp, providing tremendous computing capabilities.
5) Fifth generation (1980s-) began exploring artificial intelligence and included desktop, laptop, palmtop, server and super computer variants for different needs.

Evolution-of-Information-Technology
This document provides an overview of the four main ages in the history of information technology: pre-mechanical (3000 BC - 1450 AD), mechanical (1450-1840), electromechanical (1840-1940), and electronic (1940-present). It describes some of the key technological developments that occurred in each age, including early forms of communication like alphabets and paper, early mechanical calculators like the abacus, important inventions like the telegraph and telephone, and the first programmable computers like ENIAC which paved the way for modern electronic computers.
Ict in medicine
Computer systems and the internet have greatly improved healthcare in several ways:
1. Electronic medical records allow doctors to access complete patient histories instantly and share information between hospitals. Computerized prescriptions reduce errors.
2. Diagnostic tools like CT scans, MRIs, and ultrasounds can identify medical issues much faster and more accurately than before. Monitoring equipment keeps close tabs on patients' vital signs.
3. Treatments are also enhanced through robotics in surgery, pacemakers, ventilators, and prosthetics that can mimic natural limb movement. Online support groups and research databases help patients.
4. However, self-diagnosis online risks missing issues, and purchasing medications without a prescription
What is abacus Maths
Abacus is a method used to improve mathematical skills in kids in an intelligent and playful way. It is considered to be the fastest way of learning math thereby helping improve the problem-solving ability in kids.
It’s an ancient multi-sensory calculating tool, that helps kids understand math in an easy and interesting manner. Abacus a Chinese calculator also called “Suanpan” and has been used for more than 2,000 years back.
Introduction To Computer and Early Calculating Devices
The document provides a history of computing devices from ancient times to modern mechanical computers. It discusses early counting devices like the abacus used as early as 3000 BC. It then outlines the development of mechanical calculating machines including Napier's Bones in 1614, the slide rule, Pascal's Pascaline in 1642 which could add and subtract, and Leibnitz's device in 1672 which could perform all basic math operations. It concludes with the loom invented by Joseph Marie Jacquard in 1790 which used punched cards to control threads, introducing a key concept for later programmable computers.
History of computer electromechanical age
The electromechanical age from 1840-1940 saw important advances that enabled the development of early computers. Key inventions included Alessandro Volta's battery in 1800, which provided a reliable source of electricity and allowed information to be encoded as electrical signals. Samuel Morse invented the telegraph in 1832 for electrical communication of text messages. Alexander Graham Bell invented the telephone in 1876 for bidirectional voice communication. These inventions established telecommunication networks powered by electricity. Early electromechanical computing devices were also developed, such as tabulating machines in the 1850s, the Comptometer mechanical adding machine in 1885, and Herman Hollerith's punched card tabulating system used for the 1890 US Census.

Computer History
The first computers were human "computers", predominantly women, who performed calculations by hand. Early mechanical aids included the abacus and Napier's Bones. The first programmable digital computer was the Harvard Mark I, built in 1944. The ENIAC, completed in 1946, was the first fully electronic general-purpose computer. The integrated circuit, invented in 1958, led to smaller, more powerful computers and the development of the microprocessor in the 1970s enabled personal computers. Bill Gates left Harvard to start Microsoft and write software for the Intel-based IBM PC, launched in 1981, which popularized personal computing.

The document provides a detailed history of the development of computing from ancient times through the modern era. It discusses early counting devices like the abacus, followed by mechanical calculators in the 1500s-1800s. Punched cards and programmable computers using vacuum tubes were developed in the 1930s-40s. The stored program concept was pioneered in the 1940s, leading to general purpose computers. The invention of the microprocessor in the 1970s enabled the personal computer revolution. The document also summarizes the development of the Internet from early concepts in the 1960s to the creation of ARPANET in the late 1960s.
History of Computer & Generations of Computer
The introduction of electric power in the 19th century led to the rise of electrical and hybrid electro-mechanical devices to carry out both digital (Hollerith punch-card machine) and analog (Bush’s differential analyzer) calculation. Telephone switching
came to be based on this technology, which led to the
development of machines that we would recognize as early computers.

History of the computer
A comprehensive look at the history and development of the computer. Links to YouTube videos that can enhance student learning or expand the depth and time spent on the topic are included.
History of the computer
Charles Babbage is considered the father of the computer. He began designing the difference engine in 1821. The abacus, invented over 5000 years ago in China, was one of the earliest devices used for calculation. The first generation of computers from 1940-1956 used vacuum tubes as their electronic technology. The ENIAC was the first electronic digital computer and used around 18,000 vacuum tubes. Transistors replaced vacuum tubes in the second generation from 1956-1963, and integrated circuits replaced transistors in the third generation from 1964-1971.

The Four Basic Periods of Computer History
The four basic periods of computer history can be divided into the following:
Pre-mechanical Age – it involves the basic system of writing and alphabets like petroglyphs, ideographs, cuneiforms, the invention of pen and paper, and the first calculator ‘abacus’.
Mechanical Age – it involves the start of the information explosion where machines are now helping with the creation and transmission of information through a wider audience than in the pre-mechanical age.
Electromechanical Age – this is the start of telecommunications. Telegraphs, telephone, and radio are the highlights of this age.
Electronic Age – this is where we are today where computers are programmable and electric.
History of computer
The document summarizes the history of computers in three ages: the dark ages from 3000 BC to 1890 AD, when early mechanical calculating devices were developed; the middle ages from 1890 to 1944, bringing advances like the Harvard Mark I and ENIAC electronic computers; and the modern ages from 1944 onward, marked by IBM's System/360 in 1964, the Apple I in 1976, the IBM PC in 1981, and the Macintosh in 1984.
Introduction to computation history
Charles Babbage developed plans for mechanical general-purpose computers in the early 19th century, including the Analytical Engine which had features resembling modern computers like stored programs. However, his engines were never fully implemented due to technical limitations. The document then discusses the development of computing technology from mechanical devices to modern electronic digital computers, highlighting important inventions, people, and milestones along the way such as the abacus, Pascaline calculator, Boolesian logic, ENIAC, and the integrated circuit.
Computer history 2 2010
The document provides a chronological overview of milestones in the development of computing technology from 2500 BCE to 1939:
- The abacus, developed in China around 2500 BCE, was the first tool used for calculation. Static electricity was described by the Greek philosopher Thales of Miletus around 600 BCE.
- The Romans used an abacus with pebbles in 500 BCE. The slide rule was invented in 1633. Blaise Pascal invented the mechanical adding machine in 1642.
- Gottfried Leibniz developed a gear-based calculating machine in 1671. Charles Babbage invented the first programmable mechanical computer, the Analytical Engine, in 1833.

Types of Data Processing
This document discusses five types of data processing: manual, mechanical, electronic, real-time, and batch. Manual processing involves human intervention and is prone to errors. Mechanical processing uses machines like calculators to perform calculations more easily. Electronic data processing (EDP) uses computers to process data electronically. Real-time processing inputs, processes, and outputs data continuously in a short time period. Batch processing collects transactions over time then enters, processes, and produces results in batches.
Computer history
The document traces the history and development of computing devices from ancient counting aids like the abacus to modern computers. It discusses pioneers like Blaise Pascal who invented the first mechanical calculator in 1642. Major developments included Charles Babbage's analytical engine in 1833, Howard Aiken's Mark 1 in 1944, the ENIAC in 1946, the invention of the transistor in 1948, the Altair kit computer in 1975, the IBM PC in 1981, and the Apple Macintosh in 1984. The eras of computing are defined from first generation vacuum tube computers to fourth generation personal computers and a predicted fifth generation of parallel processing and superconducting computers.
Changing the Constitution
This document discusses amending or revising the Philippine constitution. It explains that the constitution can be changed through a cumbersome process rather than ordinary legislation, and that sovereignty resides with the people who must approve any changes. It distinguishes that an amendment changes part of the constitution while revision rewrites the entire document. The steps for changing the constitution involve proposals from the upper house, lower house of Congress, or a constitutional convention, with final approval requiring a plebiscite of qualified voters. People can also directly propose amendments through a petition process.
Different Types of Doctors & Their Income
The document discusses different types of doctors and their specializations. It defines the differences between physicians and doctors, with doctors requiring more education and training including residencies. It then lists and defines various medical specializations like cardiologists, neurologists, orthopedic surgeons, and others. It also provides data on average yearly salaries for different doctor specializations, ranging from pediatricians and family medicine doctors earning around $156,000-165,000 to radiologists, orthopedic surgeons, and cardiologists among the lowest paid at around $309,000-315,000 and dermatologists and ophthalmologists among the highest paid at around $270,000-283,000.
A DefInition Of GoD
This poem describes the author's conception of God. In 3 sentences:
God fills the gaps in human imperfection and searches out forlorn sinners. He comes uninvited to match man's earthly passions with omnipresence, and moves in when all else have fled to stir wilted leaves to life. The poem depicts God as being as human as mathematics, reigning within the geometry of love without beginning or end to atone for human imperfection and worship man everywhere by making amends.
Methods of Inquiry
This document discusses several methods of determining what is true or valid, including tradition (the Method of Tenacity), intuition based on gut feeling or prior experience, and empirical observation through the senses (as in the saying "to see is to believe"). It also mentions using logical reasoning and rationality to arrive at answers or beliefs.
Reasoning & Inference
This document discusses different types of logical reasoning and inference. It defines immediate inference as deriving a new proposition from one original proposition by rearranging its terms while maintaining the same meaning. Syllogism is forming a conclusion based on two or more premises. Conversion, obversion, and contraposition are types of eduction where a new proposition is formed by changing subject and predicate terms or their contradictories. The inverse combines conversion, obversion, and contraposition.
Body System
This document contains a diagram of the major organs and structures of the human digestive, urinary, reproductive, skeletal, and muscular systems. The digestive system organs include the esophagus, liver, stomach, small and large intestines, appendix, and rectum. The urinary system contains the kidneys, ureters, bladder, and urethra. Reproductive organs shown are the ovaries, uterus, vagina, prostate gland, testes, and associated ducts. Key bones of the skeleton include the skull, vertebrae, ribs, sternum, pelvis, and long bones of the arms and legs. Several muscles are labeled, such as the biceps, triceps, and muscles
Pioneers of Radiology

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Chris Jones, Director of Product Management at BrainChip , presents the “Temporal Event Neural Networks: A More Efficient Alternative to the Transformer” tutorial at the May 2024 Embedded Vision Summit.
The expansion of AI services necessitates enhanced computational capabilities on edge devices. Temporal Event Neural Networks (TENNs), developed by BrainChip, represent a novel and highly efficient state-space network. TENNs demonstrate exceptional proficiency in handling multi-dimensional streaming data, facilitating advancements in object detection, action recognition, speech enhancement and language model/sequence generation. Through the utilization of polynomial-based continuous convolutions, TENNs streamline models, expedite training processes and significantly diminish memory requirements, achieving notable reductions of up to 50x in parameters and 5,000x in energy consumption compared to prevailing methodologies like transformers.
Integration with BrainChip’s Akida neuromorphic hardware IP further enhances TENNs’ capabilities, enabling the realization of highly capable, portable and passively cooled edge devices. This presentation delves into the technical innovations underlying TENNs, presents real-world benchmarks, and elucidates how this cutting-edge approach is positioned to revolutionize edge AI across diverse applications.GraphRAG for LifeSciences Hands-On with the Clinical Knowledge Graph

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
