1st QE Flashcards
ICT
Information and Communications Technology
refers to all technology that is used to handle
telecommunications and access information. It also includes broadcast media, management systems, and
network-based control
ICT
the convergence of several technologies including the internet and
wireless medium, but primary focus is on the access and sharing of information and communications
ICT
Components of ICT
Cloud Computing & Internet Access
Remote delivery of computing services (servers, storage, databases, applications) over
the internet, accessible on demand.
Cloud Computing
enables users to access and use computing resources (such as storage,
processing power, and software) over the internet, providing scalability and flexibility
Cloud Computing
Provides cloud-based services for businesses and individuals, including virtual machines, storage, databases, and analytics
tools.
Microsoft Azure
Offers a suite of cloud computing services like computer engine, storage, big data, and machine learning for businesses
and developers.
Google Cloud Platform
Connection to the global network of computers and information resources.
Internet Access
It is a facility or service that provides connectivity for a computer, a computer network, or other network device to the Internet
Internet Access
Types of Internet Access
Wi-Fi (Wireless Fidelity), LTE (Long Term Evolution) & 5G Technology
a widely used wireless networking technology that enables devices to connect to the internet and each other without physical
cables. It operates in a specific radio frequency spectrum, typically 2.4 GHz or 5
GHz, and transmits data using radio waves.
Wi-Fi (Wireless Fidelity)
a cellular network technology that provides
high-speed wireless internet access for mobile devices like smartphones and tablets. It was designed as an upgrade to earlier 3G networks, offering significantly faster data speeds, lower latency, and improved network capacity.
LTE (Long Term Evolution)
the latest generation of cellular network technology, promising even faster speeds, lower latency, and significantly improved network capacity compared to its predecessors. It aims to revolutionize various aspects of our lives beyond just mobile internet access, enabling new applications and services
5G Technology
Defined as a collection of individual raw facts or statistics. It can come in the form of text,
observations, figures, images, numbers, graphs, or symbols.
Data
refers to the massive volume of structured and unstructured data that organizations and systems generate daily. This data comes from a wide range of sources, including sensors, social media, web interactions, transaction records, and more
Big Data
Refers to all equipment and programs that are used to process and communicate
information. Tools and methods used to transmit and receive information electronically.
Communication Technologies
Types of Communication Technologies
Machine-to-Machine communication, Human-to-Machine communication & Wearable Technology
M2M communication refers to the
direct exchange of data and instructions between the various sensors and
devices embedded within them, without human intervention.
Machine-to-Machine communication
HMI focuses on how humans interact with
their wearable
Human-to-Machine communication
M2M and HMI work together to create the magic of wearable technology. M2M provides the underlying data exchange and intelligence, while HMI allows humans to access and control this technology seamlessly. As both technologies continue to evolve, we can expect even more sophisticated and intuitive ways for wearables to communicate, both with each other and with us.
Wearable Technology
Exchange of information or goods electronically, often involving payment or data transfer.
Transactions
Physical components of an ICT system, including computers, network devices, and
peripherals.
Hardware
Set of instructions that tell hardware how to perform specific tasks.
Software
- Online shopping: Purchasing goods and services through e-commerce
websites and platforms. - Mobile banking: Making payments, transferring funds, and managing
bank accounts through mobile apps.
Transactions
- Personal computer: Desktop or laptop used for work, entertainment, and
communication. - Smartphones: Mobile devices with internet access, camera, and various
applications.
Hardware
- Operating system: Manages the computer’s hardware and provides a
platform for running other programs. (e.g. Windows, macOS, Linux) - Productivity software: Tools for document creation, spreadsheets,
presentations, and communication. (e.g. Microsoft Office, Google
Workspace)
Software
Web Generation: From Static Pages to Interconnected Ecosystems
Web 1.0 (1991-1995), Web 2.0 (2005-present) &Web 3.0 (emerging)
The dawn of the web, characterized by static HTML pages and limited user interaction.
Web 1.0 (1991-1995)
User-generated content, social media, and dynamic applications took center stage. Platforms like YouTube and Wikipedia redefined online engagement.
Web 2.0 (2005-present)
The web as a more immersive and decentralized space,
fueled by blockchain technology and semantic web concepts. Think virtual reality
experiences and AI-powered personalized content.
Convergent Technology: Blurring the Lines Between Devices and Services
The Internet of Things (IoT), Cloud Computing, & Convergence of Devices and Services
