FM-AA-CIA-15 Rev. 0 10-July-2020 Study Guide in (GE111 – Living in the IT ERA) Module No. 1 STUDY GUIDE FOR MODULE NO. 1 Chapter 1 – Introduction to the Information and Communication Technology MODULE OVERVIEW In this chapter, we are going to explore the concept of Information and Communication Technology (ICT), its evolution and its nature. We will also understand the practical application of ICT in everyday life. the impacts of ICT in different areas of specialization and the current trends and emerging technologies. MODULE LEARNING OBJECTIVES At the end of this, students are expected to: Understand the evolution of technology over the years Explain how technology can be used in different aspects of the society Discuss the impact of Technology in different areas of specialization Identify the current trends in technology LEARNING CONTENTS (Evolutions of Information and Communication Technology) Information and Communication Technology (ICT) is a term used to describe technologies in manipulating and communicating information, especially in relation to modern telecommunication systems as they have evolved to intensive use of computing technology coupled with the enormous increase in communications between computers relying on the telecommunications infrastructure to do so. The two areas have increasingly merged as telecommunications has moved from analog to digital and then to packet technologies, and as the Internet has emerged to become one of the dominant data communications systems in use today. The very first forms of ICT and all the forms leading up to our current forms of ICT make our current technologies what they are today. The evolution of the first ICT to our current form of ICT goes through 4 stages, Premechanical, Mechanical, Electromechanical and Electronic. These 4 stages helped ICT evolve and adapt to the latest forms of ICT. 1. Premechanical The premechanical age of technology is the earliest known form of ICT. It can be defined as the time between 3000B.C. and 1450A.D. Which is a very long time ago. But this is when humans first started communicating and try to do this in several ways including trying to use language or simple symbols and picture known as petroglyths which were usually carved into rock. These Petrolglyths made up stories, messages and warnings. Early alphabets were developed such as the Phoenician alphabet. As Alphabets became more popular and more commonly used for writing information down, pens and paper began to develop. It just started off as marks on wet clay, but then later paper was created out of Papyrus Plant. The most popular kind of paper was made by the Chinese who made paper from rags. Now that people were writing a lot of information down, they needed ways to keep it all in storage permanently. This is where the first books and libraries were developed. You've probably heard or seen Egyptian scrolls which was one popular way of writing down information permanently. Some people were binding information together in a book like form. Also during this period were the first numbering systems. Around 100A.D. was when the first 1-9 system was created by people from India. However, it wasn’t until 875A.D. (775 years later) that the number 0 was invented. And yes, now that numbers were created, people wanted stuff to do with them so they created calculators. A calculator was the very first sign of an information processor. The popular model of that time was the abacus. 2. Mechanical The mechanical age is when we first start to see connections between our current technology and its ancestors. The mechanical age can be defined as the time between 1450 and 1840. There was a huge explosion of interest in this era, resulting in more technologies being developed. Technologies like the slide rule (Which was an analog computer used for multiplying and dividing) were invented. Blaise Pascal invented the Pascaline which was a very popular mechanical computer. Charles Babbage developed the difference engine which tabulated polynomial equations using the method of finite differences. There were lots of PANGASINAN STATE UNIVERSITY 1  FM-AA-CIA-15 Rev. 0 10-July-2020 Study Guide in (GE111 – Living in the IT ERA) Module No. 1 different machines created during this era and while we have not yet gotten to a machine that can do more than one type of calculation in one, like our modern-day calculators, we are still learning about how all our all- in-one machines started. Also, if you look at the size of the machines invented in this time compared to the power behind them it seems (to us) ridiculous to understand why anybody would want to use them, but to the people living in that time ALL these inventions were HUGE. 3. Electromechanical Now we are finally getting close to some technologies that resemble our current technology. The electromechanical age can be defined as the time between 1840 and 1940. These are the beginnings of telecommunication. The telegraph was created in the early 1800s. Morse code was created by Samuel Morse in 1835. The telephone (one of the most popular forms of communication ever) was created by Alexander Graham Bell in 1876. The first radio developed by Guglielmo Marconi in 1894. All of these were extremely crucial emerging technologies that led to big advances in the information technology field. The first large-scale automatic digital computer in the United States was the Mark 1 created by Harvard University around 1940. This computer was 8ft high, 50ft long, 2ft wide, and weighed 5 tons - HUGE. It was programmed using punch cards. How does your PC match up to this hunk of metal? It was from huge machines like this that people began to look at downsizing all the parts to first make them usable by businesses and eventually in your own home. 4. Electronic (Our current Technology) The electronic age is what we currently live in. It can be defined as the time between 1940 and right now. The ENIAC was the first high-speed, digital computer capable of being reprogrammed to solve a full range of computing problems. This computer was designed to be used by the U.S. Army for artillery firing tables. This machine was even bigger than the Mark 1 taking up 680 square feet and weighing 30 tons - HUGE. It mainly used vacuum tubes to do its calculations. There are 4 main sections of digital computing. The first was the era of vacuum tubes and punch cards like the ENIAC and Mark 1. Rotating magnetic drums were used for internal storage. The second generation replaced vacuum tubes with transistors, punch cards were replaced with magnetic tape, and rotating magnetic drums were replaced by magnetic cores for internal storage. Also, during this time high-level programming languages were created such as FORTRAN and COBOL. The third generation replaced transistors with integrated circuits, magnetic tape was used throughout all computers, and magnetic core turned into metal oxide semiconductors. An actual operating system showed up around this time along with the advanced programming language BASIC. The fourth and latest generation brought in CPUs (central processing units) which contained memory, logic, and control circuits all on a single chip. The personal computer was developed (Apple II). The graphical user interface (GUI) was developed.

In education, teachers, students, researchers, and school administrators benefits from the usage of ICT. b) BANKING The computer is the nerve center of the banking system around the world. It functions to control the entire banking system that also includes ‘Electronic Banking Services’. Electronic banking provides 24-hour services. The services include: a. Automated Teller Machine (ATM) PANGASINAN STATE UNIVERSITY 3  FM-AA-CIA-15 Rev. 0 10-July-2020 Study Guide in (GE111 – Living in the IT ERA) Module No. 1 b. Cheque Deposit c.

Now with the Internet, news or messages are sent via e-mail to friends, business partners or to anyone efficiently. With the capability of bandwidth, broadband and connection speed on the Internet, any information can travel fast and at an instant. It saves time and is inexpensive. LOWER COMMUNICATION COST Using the Internet is cost-effective than the other modes of communication such as telephone, mailing or courier service. It allows people to have access to large amounts of data at a very low cost. With the Internet we do not have to pay for any basic services provided by the Internet. Furthermore, the cost of connection to the Internet is relatively cheap. RELIABLE MODE OF COMMUNICATION Computers are reliable. With the internet, information could be accessed and retrieved from anywhere and at any time. This makes it a reliable mode of communication. However, the input to the computer is contributed by humans. If the data passed to the computer is faulty, the result will be faulty as well. This is related to the term GIGO. GIGO is a short form for Garbage In Garbage Out. It refers to the quality of output produced according to the input. Normally bad input produces bad output. EFFECTIVE SHARING OF INFORMATION With the advancement of ICT, information can be shared by people all around the world. People can share and exchange opinions, news, and information through discussion groups, mailing list and forums on the Internet. This enables knowledge sharing which will contribute to the development of knowledge-based society. PAPERLESS ENVIRONMENT ICT technology has created the term paperless environment. This term means information can be stored and retrieved through the digital medium instead of paper. Online communication via emails, online chat and instant messaging also helps in creating the paperless environment. BORDERLESS COMMUNICATION Internet offers fast information retrieval, interactivity, accessibility, and versatility. It has become a borderless source for services and information. Through the Internet, information and communication can be borderless. SOCIAL PROBLEMS There are some negative effects of ICT. It has created social problems in the society. Nowadays, people tend to choose online communication rather than having real time conversations. People tend to become more individualistic and introvert. HEALTH PROBLEMS A computer may harm users if they use it for long hours frequently. Computer users are also exposed to bad posture, eyestrain, physical and mental stress. To solve the health problems, an ergonomic environment can be introduced. For example, an ergonomic chair can reduce back strain and a screen filter is used to minimize eye strain. LEARNING CONTENTS (Current Trends and Emerging Technologies) Technology today is evolving at such a rapid pace, enabling faster change and progress, causing an acceleration of the rate of change, until eventually, it will become exponential PANGASINAN STATE UNIVERSITY 5  FM-AA-CIA-15 Rev. 0 10-July-2020 Study Guide in (GE111 – Living in the IT ERA) Module No. 1 1. Artificial Intelligence (AI) and Machine Learning Artificial Intelligence is a method of making a computer, a computer-controlled robot, or a software think intelligently like the human mind. AI is accomplished by studying the patterns of the human brain and by analyzing the cognitive process. The outcome of these studies develops intelligent software and systems. Some of the tasks performed by AI-enabled devices include: Speech recognition Object detection Solve problems and learn from the given data Plan an approach for future tests to be done Machine Learning is a core sub-area of Artificial Intelligence (AI). ML applications learn from experience (or to be accurate, data) like humans do without direct programming. When exposed to new data, these applications learn, grow, change, and develop by themselves. In other words, machine learning involves computers finding insightful information without being told where to look. Instead, they do this by leveraging algorithms that learn from data in an iterative process.. 2. Robotic Process Automation (RPA) Robotic Process Automation is the use of software with Artificial Intelligence (AI) and machine learning (ML) capabilities to handle high-volume, repeatable tasks that previously required humans to perform. Some of these tasks include: Addressing queries Making calculations Maintaining records Making transactions 3. Edge Computing Edge computing is designed to help solve some of those problems to bypass the latency caused by cloud computing and getting data to a datacenter for processing. It can exist “on the edge,” if you will, closer to where computing needs to happen. For this reason, edge computing can be used to process time-sensitive data in remote locations with limited or no connectivity to a centralized location. In those situations, edge computing can act like mini datacenters. Edge computing will increase as use of the Internet of Things (IoT) devices increases. 4. Quantum Computing Quantum computing, which is a form of computing that PANGASINAN STATE UNIVERSITY 6  FM-AA-CIA-15 Rev. 0 10-July-2020 Study Guide in (GE111 – Living in the IT ERA) Module No. 1 takes advantage of quantum phenomena like superposition and quantum entanglement. This amazing technology trend is also involved in preventing the spread of the coronavirus, and to develop potential vaccines, thanks to its ability to easily query, monitor, analyze and act on data, regardless of the source. Another field where quantum computing is finding applications in banking and finance, to manage credit risk, for high-frequency trading and fraud detection. Quantum computers are now a multitude times faster than regular computers and huge brands like Splunk, Honeywell, Microsoft, AWS, Google, and many others are now involved in making innovations in the field of Quantum Computing. 5. Virtual Reality and Augmented Reality Virtual Reality (VR) and Augmented Reality (AR), and Extended Reality (ER). VR immerses the user in an environment while AR enhances their environment. Although this technology trend has primarily been used for gaming thus far, it has also been used for training, as with Virtual Ship, a simulation software used to train U.S. Navy, Army and Coast Guard ship captains. 6. Blockchain Blockchain is a list of records called blocks that store data publicly and in chronological order. The information is encrypted using cryptography to ensure that the privacy of the user is not compromised and data cannot be altered. Information on a Blockchain network is not controlled by a centralized authority, unlike modern financial institutions. The participants of the network maintain the data, and they hold the democratic authority to approve any transaction which can happen on a Blockchain network. Therefore, a typical Blockchain network is a public Blockchain. 7. Internet of Things (IoT) According to the Internet, it’s “the interconnection via the Internet of computing devices embedded in everyday objects, enabling them to send and receive data.” At a consumer level, these devices can be placed in our cars, phones, appliances, medical equipment, wristbands, livestock and more. At an industrial level, these devices can be in machinery, shipping equipment, vehicles, robots, warehouses and more. But where the devices are located matters less than what they do. And what they do is “talk” to each other, sharing data and getting feedback based on that data and all the other data that is being generated, analyzed, and acted on. 8. 5G 5G services are expected to revolutionize our lives. by enabling services that rely on advanced technologies like AR and VR, alongside cloud-based gaming services like Google Stadia, NVidia GeForce Now and much more. It is expected to be used in factories, HD cameras that help improve safety and traffic management, smart grid control and smart retail too. 9. Cyber Security Cyber security is an area that covers how to defend devices and services from electronic attacks by nefarious actors such as hackers. While there can be offensive components to cyber security, most of today's professionals focus on determining the best way to defend everything from computers and smartphones to networks and databases from attackers.
