History Of Computer By Ian Fred Caballero
This document provides a history of computers from the 19th century to modern times. It discusses the origins of computer design by Charles Babbage and then summarizes the five generations of computers: 1) Vacuum tubes (1940s-1950s), 2) Transistors (1950s-1960s), 3) Integrated circuits (1960s-1970s), 4) Microprocessors (1970s-2010s), and 5) Artificial intelligence (2010s-future). It also profiles the 5 biggest computer companies today: Apple, Samsung, IBM, Foxconn, and HP.
L13 The Rise of the Machine
Did you know that the term "Computer" once meant a profession? And what did people or computers actually do? They computed mathematical problems. Some problems were tedious and error prone. And it is not surprising that people started to develop machines to aid in the effort. The first mechanical computers were actually created to get rid of errors in human computation. Then came tabulating machines and cash registers. It was not until telephone companies were well established that computing machines became practical.
First computers were huge mainframes, but soon minicomputers like DEC’s PDP started to appear. The transistor was introduced in 1947, but its usefulness was not truly realized until in 1958 when the integrated circuit was invented. This led to the invention of the microprocessor. Intel, in 1971, marketed the 4004 – and the personal computer revolution started. One of the first Personal Computers was MITS’ Altair. This was a simple device and soon others saw the opportunities.
In this lecture we start our coverage of computing and look at some of the early machines and the impact they had.

The document discusses the evolution of communication and information technology (ICT). It defines ICT as the use of electronic devices and software to store, process, transmit and retrieve information. Communication has evolved from early forms like symbols and poetry to modern technologies like the Internet, email and video conferencing. The timeline traces important technology milestones from the development of writing systems to the invention of computers, internet, and smartphones. It also summarizes the four generations of computer development from the 1940s to present, focusing on innovations in hardware technology that drove each generation forward.
L14 Software and Machine Learning
After the computing industry got started, a new problem quickly emerged. How do you operate this machines and how to you program them. The development of operating systems was relatively slow compared to the advances in hardware. First system were primitive but slowly got better as demand for computing power incresed. The ideas of the Graphical User Interfaces or GUI (Gooey) go back to Doug Engelbarts Demo of the Century. However, this did not have much impact on the computer industry. One company though, Xerox, a photocopy company explored these ideas with Palo Alto Park. Steve Jobs of Apple and Bill Gates of Microsoft took notice and Apple introduced first Apple Lisa and the Macintosh. In this lecture on we look so lessons for the development of software, and see how our business theories apply.

L16 A World Wide Network
The Internet grew out of US efforts to build the ARPANET, a network of peer computers built during the cold war. The two major players were military and academia. The network was simple and required no efforts for security or social responsibility. The early Internet community was mainly highly educated and respectable scientist. In the early 1990s the World Wide Web, a hypertext system is introduced, and soon browsers start to appear, leading the commercialization of Net. New businesses emerge and a technology boom known as the dot-com era.
The network, now over 40, is being stretched. Problems such as spam, viruses, antisocial behaviour, and demands for more content are prompting reinvention of the Net and threatening its neutrality. Add to this government efforts to regulate and limit the network.
In this lecture we look at the Internet and the impact of the network. We will also look at the future of the Internet.
1 history of information technology
This document provides a history of information technology from the electromechanical age to modern times. It describes how early technologies like the telegraph, telephone, and radio could communicate information but not store it. Early computers like the Mark I, ENIAC, EDSAC, and UNIVAC used vacuum tubes, punch cards, and magnetic tape. Advances in integrated circuits, microprocessors, and software led to smaller personal computers in the 1970s and graphical user interfaces in the 1980s. The creation of the personal computer democratized information technology beyond just government and business use.

L15 Augmented and Virtual Reality
The document discusses the evolution of computing devices from mainframes to modern smartphones and tablets. It outlines how personal computers have transitioned from specialized machines accessed through terminals to ubiquitous internet-connected devices incorporating touchscreens, voice control, augmented and virtual reality. The desktop metaphor is disappearing as interactions move beyond mice and keyboards to gesture, audio and touch-based interfaces. Emerging technologies like wearables, smart home devices and augmented reality suggest computing will continue integrating into everyday objects and environments.
L18 The Mobile Revolution
The ideas for cellular phones were developed in the 1940s. However, it was not until the microprocessor becomes available that practical commercial solutions are possible.
Today there are more than 4.7 billion unique mobile phone subscriptions in the world and of them about 2 billion are smartphones. This device is so powerful that people check it over 40 times a day.
In this lecture we look mobile. We also look at the history of communication since the telegraph and how the moble market developed in the 80s and 90s until the iPhone was released in 2007. That same year Western Union stopped sending telegraph messages.

Information Technology PowerPoint Project
Information technology (IT) refers to the use of computers and telecommunications to store, retrieve, transmit, and manipulate data or information. It is considered a subset of information and communications technology. Key aspects of IT include computer hardware, software, databases, data transmission and manipulation. The history of IT began with early mechanical devices and progressed through electromechanical and electronic computers. Modern databases, structured query language, data warehouses, and data mining have enabled effective analysis and use of massive amounts of digital information. IT is applied in business, government, healthcare and other organizations to automate processes and provide information for decision making. Ethical issues associated with IT include breaches of copyright and privacy.

Generation of Computers: A Survey
Nothing epitomizes modern life better than the
computer. Computers are such an integral part of our everyday
life now most people take them and what they have added to life
totally for granted. Even more so the generation who have grown
from infancy within the global desktop and laptop revolution
since the 1980s. The history of computer development is often
referred to in reference to the different generations of computing
devices. A generation refers to the state of improvement in the
product development process. This term is also used in the
different advancements of new computer technology. As new
technology was emerging, it was being used in the making of
computer. With each new generation, the circuitry has gotten
smaller and more advanced than the previous generation before
it. As a result of the miniaturization, speed, power, and com-
puter memory has proportionally increased. New discoveries are
constantly being developed that affect the way we live, work and
play.

History of comp
Generations of computers have been divided into five generations based on the underlying technologies used. The first generation used vacuum tubes, were enormous in size, and had low processing speeds. The second generation used transistors, were smaller in size, and had faster processing speeds. The third generation used integrated circuits, which made the computers more reliable and cost effective. The fourth generation used microprocessors, which placed all computer components onto a single chip and allowed for personal computers. Current computers are considered fifth generation with advancements in artificial intelligence and portable devices.

What are Web Standards and why were they established? Why should web developers use web standards?
Originally presented on 08/02/2010 by Chris Fagg.
W3 c validation
1. W3C stands for the World Wide Web Consortium, which is an international organization that sets web standards.
2. W3C validation checks that a website's code follows W3C formatting standards for HTML and CSS.
3. Validating a website improves usability, functionality, and efficiency by reducing errors and improving code structure.
Web architecture - overview of techniques.
The document discusses various web application architecture techniques, including:
- Popular frameworks like Sinatra that use REST APIs and MVC patterns on the client-side.
- Reactive frameworks like Shiny that use websockets for real-time updates between the client and server.
- Challenges in building reactive applications, as infrastructure is still maturing to support callbacks without blocking.
- Other approaches to reactivity on the server including actors, channels, and reactive extensions.
- The document concludes that there is no single ideal architecture, as techniques are continually invented and re-invented over time.

History of comp
Generations of computers have been divided into five generations based on the underlying technologies used. The first generation used vacuum tubes, were enormous in size, and had low processing speeds. The second generation used transistors, were smaller in size, and had faster processing speeds. The third generation used integrated circuits, which made the computers more reliable and cost effective. The fourth generation used microprocessors, which placed all computer components onto a single chip and allowed for personal computers. Current computers are considered fifth generation with advancements in artificial intelligence and portable devices.

THE EVOLUTION OF HUMANITY'S GREATEST INVENTION, THE COMPUTER, AND ITS FUTURE.pdf
This article aims to present how the computer, humanity's greatest invention, evolved and how its most likely future will be. The computer is humanity's greatest invention because the worldwide computer network made possible the use of the Internet as the technology that most changed the world with the advent of the information society. IBM developed the mainframe computer starting in 1952. In the 1970s, the dominance of mainframes began to be challenged by the emergence of microprocessors. The innovations greatly facilitated the task of developing and manufacturing smaller computers - then called minicomputers. In 1976, the first microcomputers appeared whose costs represented only a fraction of those practiced by manufacturers of mainframes and minicomputers. The existence of the computer provided the conditions for the advent of the Internet which is undoubtedly one of the greatest inventions of the 20th century, whose development took place in 1965. At the beginning of the 21st century, cloud computing emerged, which symbolizes the tendency to place all the infrastructure and information available digitally on the Internet. Current computers are electronic because they are made up of transistors used in electronic chips that have limitations given that there will be a time when it will no longer be possible to reduce the size of one of the components of the processors, the transistor. Quantum computers have been shown to be the newest answer in Physics and Computing to problems related to the limited capacity of electronic computers. Canadian company D-Wave claims to have produced the first commercial quantum computer. In addition to the quantum computer, Artificial Intelligence (AI) can reinvent computers.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

Editor's Notes
- Professor John Atanasoff was seeking a tool to help his students solve differential equations.
- Mark I was a 51-foot-long, 8-foot-tall monster that used noisy electromechanical relays to calculate five or six times faster than a person could, but it was far slower than a modern $5 pocket calculator.
- ENIAC was a 30-ton behemoth with 18,000 vacuum tubes that broke down, on average, once every seven minutes. It wasn’t completed until two months after the end of the war, but it convinced its creators that large-scale computers were commercially feasible.
- Encyclopedia Britannica (http://www.britannica.com/) has a lot of good information about the evolution of computers.
- Go to e-Bay, (http://search.ebay.com/search/search.dll?MfcISAPICommand=GetResult&ht=1&SortProperty=MetaEndSort&query=commodore+computer&?query=commodore+computers), and show your students how much an old Commodore computer costs these days. They’ll be surprised! Question : Did Bill Gates ever work for Apple? Answer: Yes, Bill Gates worked for Apple before starting his own company. There has always been a lot of debate about the similarities between the Apple Operating System and Bill Gates’ Windows, because many people believe that, despite claims to the contrary, Windows is actually based on the Apple OS concepts.
- In 1994, only 3 million people were connected to the Internet; by the end of 2002, over 550 million people had Internet connections. More than 54 percent of all American households are connected to the Internet; before the first decade of the 21st century is over, 90 percent of U.S. households will likely be connected, making the Internet almost as universal as the television and the telephone. The United States leads the world in Internet activity, but the rest of the world is catching up. About 34 percent of all Europeans were online in 2001, and their numbers are rising quickly. By 2006, some predict, over 79 percent of Europeans will be online.
