IT2221 THE MODERN COMPUTING Virtualization The Current Status of Computing This technology simulates hardware functions by creating multiple virtual machines on a physical server that acts as a hardware device. With the rapid increase of mobile devices and the ability to connect Its essence is to detach software from hardware by converting things, humans are in a post-PC era where connected devices are “physical” devices into “logical” folders or files. replacing traditional desktop and laptop computers. Examples of the application of virtualization include: Here are some of the modern computing technologies used today. − Server virtualization, companies use one server to support Cloud Computing different functions for more structured resource applications. − In desktop virtualization, users run several desktop operating It is the application of hardware and software to deliver readily systems from a single computer. available, on-demand, and measured computing services over the − Storage virtualization lets connected devices, servers, and Internet. With this, IT services became as convenient as household applications acquire information from a centralized dashboard utilities like water and electricity. such as a cloud. The collected data is stored in a “cloud,” which symbolizes the Internet To understand their relationship, cloud computing uses virtualization compared to traditional computers that use physical devices. The use technology to achieve its purpose, as seen from virtualization of the cloud lets users open files and use applications anywhere using applications. whichever device has access to the Internet. Internet of Things (IoT) Examples of the application of cloud computing include: It is a network of an extensive range of physical objectives that − Cloud storage such as Google Drive and iCloud where users can automatically share data over the Internet. It allows faster information back up and restore local files. exchange and communication between “things” such as global − Google Translate instantly translates words, dialects, phrases, positioning systems (GPS) and laser scanners. It can be used to and web pages between English and over 100 other languages. accept, locate, monitor, and manage “things” in IoT more reasonably. − Streaming services such as Netflix, Apple TV, and Deezer manage real-time data logs. Key technologies used by IoT include: − Radio frequency identification (RFID) is found in electronic tags and smart cards. − Sensor technology detects and collects environmental signals such as temperature, humidity, and speed. − Embedded systems, where hardware and software are integrated to provide specific functions such as automated teller machines (ATM), digital cameras, and calculators. 02 Handout 1 *Property of STI [email protected] Page 1 of 3 IT2221 Big Data To show the interconnection of the modern technologies of computing, it is essential to note that Cloud Computing is the foundation of These are massive and complex datasets characterized by high Artificial Intelligence. At the same time, the Internet of Things provides volume, variety of data types, and velocity as data are collected and the raw materials used to produce the fertilizer that Big Data feeds into analyzed at ever-increasing rates. Artificial Intelligence. The data volume was small during the early stages of IT. Reading Other modern computing technologies: books and newspapers was the only option to learn relevant information as there were not enough books at school libraries. E- Fog Computing books and online news consumption now replace this traditional method. The amount of information increases with the emergence of It is an expansion of the idea of cloud computing proposed by Cisco. digitization. The data and application sets are stored in edge devices compared to the clouds of cloud computing. As the names suggest, the cloud is The applications of big data are as follows: placed up in the sky, which is distant and remote, whereas the fog is closer to the ground, wherein servers are placed near the end-users. − Banking industries use big data to track financial market activities. Network analytics and natural language processors are Fog computing allows local data analytics and management and the used to catch illegal trading activities. distribution of real-time data insights to customers in different areas − Healthcare industries use big data to acquire a sizable amount such as factories, streetlights, and commodities. of data from thousands of patients to let doctors use evidence- based medicine. Edge Computing − Education systems use big data to measure a teacher’s effectiveness to ensure a pleasant experience for students and It is decentralized and distributed cloud computing; wherein “edge” is teachers. a general concept. It deals with a computing infrastructure that is close to data sources. Artificial Intelligence (AI) The raw data in edge computing is analyzed locally instead of Machines can learn from experience, adjust to new inputs, and do transferred to the cloud. It is predicted that computing is naturally human-like activities because of this technology. It has always been progressing from the cloud to the edge and that this computing regarded as the technology that can change the world on the one hand technology will be the next big thing after cloud computing. A and end it on the other. significant reason behind this is that edge computing plays a critical role in progressing IoT developments. In combination with cloud computing and big data, AI is driving a digital transformation shift in the ICT industry for higher intelligence. Various Impacts of Computing in Different Industries Examples of AI applications include facial recognition for unlocking The rise of powerful, inexpensive, easy-to-use computers has smartphones, voice recognition, chatbots, robots, virtual assistants significantly impacted business and society over the years. For such as Siri and Alexa, and e-payments. example, computing devices such as computers, embedded systems, and smartphones are used for both entertainment and productivity purposes that can affect relationships, work, and lifestyles. 02 Handout 1 *Property of STI [email protected] Page 2 of 3 IT2221 Business Organizations Government Businesses use computers to organize data effectively. Using It is a common issue for government agencies to take a longer time to applications such as Microsoft Excel and SQL Database will lessen accomplish paper and service requests. With comprehensive the amount of human error in business management. The need for computing equipment for storing public information, handling office cabinets is decreased as data spreadsheets take place in data government works makes the customer experience faster and more storage and processing. Doing so makes error-tracking easier, reliable and creates more accurate results and services. allowing businesses to arrive at better conclusions based on well- organized data sets. Robotics Banking Industries This fast-emerging field supports computers for science, engineering, research, and machines. Robots such as factory and machine robots Banking industries use computers for better transaction processes. As can help perform several tasks considered complex for human one of the most used payment methods, ATMs allow users to deposit abilities. and withdraw money anywhere and anytime easily. Additionally, physical robots are developed machines with computing Bank tellers can easily manage the files and accounts of their technology. One of the recent examples of a physical computerized customers as quickly as possible using computers. They need to input robot is Sophia the Robot, known for its human-like abilities in the user's name to access banking information in a single process. communication and expression. It is a social humanoid robot created by Hanson Robotics which was first activated in February 2016.
