In this semester, we will look at some of the usual topics (Internet, cloud, online safety, web browsers) as well as some unique topics (cutting the cord, artificial intelligence and chatbots, both Google and Microsoft tools, misinformation and conspiracy theories and even a virtual trip to Best Buy to look at some of their products).  These topics are designed to keep you informed of the latest in technology, and how we are using technology for communication.

Review the topics by going to the topics page (Topics Spring 2024 ).  Note if there is something in particular that you would like to see in a particular topic and let me know.

We will record the lesson each week (staring with Week 2) so that you can go back and learn more.  In fact, it is highly recommended that you return to the website following the Zoom lesson and review the topics on the website.  You can also use the handout and/or presentation(s) to review.

Look for the weekly email for news and announcements, and use the website for things like accessing Canvas, student registration information, announcements, course resources and more. 

How to participate in class:

As an online class, we do not always know if you are participating.  However, there are a number of ways to interact with our class.   Unfortunately, not all methods can be documented.  Where possible, try to include at least one or two ways of interacting that can be documented.  Here is an overview of how you can participate.  Those that are highlighted are activities that can be documented:

• Attending the Zoom sessions

• Reading (and responding) to weekly emails

• Visiting our course website (and commenting in an email if you have a question)

• Visiting the discussion board on Canvas and posting/answering a post

• Taking the quizzes each week 

• Watching the lesson video (and commenting if you have questions or comments)

• Talking with friends about a topic (and letting us know how it went)

• Finding documentaries online that are relevant to the topic (and letting us know either in class or on the discussion board). 

Tech Terminology Overview

In the 17 weeks that follow, we will be looking at a number of topics.  Here is an overview of some of the terms you might hear during our class.

AI (Artificial Intelligence)

AI performs tasks requiring human intelligence, like language understanding or decision-making. It's increasingly present in daily life, enhancing convenience and security.

Cache and Cookies

Cache and cookies are browser-stored data for faster, personalized internet experiences. Cache speeds up page loading, while cookies remember user preferences.

Casting

Casting refers to wirelessly transmitting content from a mobile device or computer to a television or other display screen. This allows you to view photos, videos, or other media from your phone or laptop on a larger screen, enhancing the viewing experience. It's commonly used for sharing media in a group setting or for a more immersive viewing experience. Devices like Google Chromecast or Apple AirPlay are popular for casting, and many smart TVs now come with built-in casting capabilities.

Cellular and Cellular Data

Cellular technology enables wireless network connections for mobile devices. Cellular data, used for internet access when Wi-Fi isn't available, is often limited by service plans.

Chatbots

A chatbot is a software application which uses AI and natural language processing (NLP) to interpret and respond to user queries, providing information, or performing specific tasks. They are commonly used in customer service to handle inquiries, on websites for instant responses to user questions, and in various apps for tasks ranging from scheduling to entertainment.

ChatGPT

ChatGPT is an AI-powered conversational tool assisting in various tasks, from answering questions to social interaction, accessible even for non-tech-savvy users.

 Cloud

The Cloud refers to internet-based storage, offering convenience and security for storing and accessing data from multiple devices.

Computer Virus

A computer virus is a type of malware that replicates and spreads, corrupting data or taking control of systems. Protection involves cautious online behavior and using antivirus software.

Conspiracy Theories

A conspiracy theory is a belief or explanation that suggests events or situations are secretly manipulated or controlled by a covert group or organization. Often lacking substantial evidence, these theories typically challenge mainstream understanding and can spread mistrust and misinformation.

Data, Memory, and Speed

• Data: Information processed or stored by computers.

• Memory: Hardware storing data temporarily (RAM) or permanently (hard drives).

• Speed: Performance aspect, influenced by processor speed, RAM, and internet connection.

Deep Fake

Deepfake technology creates realistic fake videos or audio, posing risks like disinformation. Critical evaluation of digital content is essential to discern authenticity.

Devices: 

There are a number of devices which are designed for communication.  They include:

• Mobile Phones: Portable devices for calls, texts, and internet via cellular networks.

• Smartphone: Advanced mobile phones with internet, email, apps, and touchscreen.

• Satellite Phone: For communication in areas without cellular service.

• Tablet: Larger than smartphones, often without voice call capabilities.

• Laptop/Desktop Computer: For emails, video conferencing, and internet tasks.

• Two-Way Radio: Short-distance communication devices like walkie-talkies.

• Television: Modern TVs also support video conferencing.

• Smart Watches: Wearable devices for basic communication, often linked to smartphones.

• Voice-activated Assistants: Devices for voice-command tasks like messaging or calls.

• Video Conferencing Equipment: Tools enhancing video meeting quality.

File Formats

File formats, indicated by extensions like ".jpg" or ".pdf", determine how data is stored and shared. Different formats serve various purposes, like image quality or document security.

Folders and Zipping

Zipping compresses files for easier sharing and storage. Most devices can zip and unzip files, simplifying digital file management.

Malware

Malware, including viruses, spyware, and ransomware, is software designed to harm or exploit devices. Understanding and avoiding malware is crucial for digital safety.

Misinformation

Misinformation refers to false or inaccurate information that is spread, often unintentionally, without malicious intent. It can lead to misunderstanding and incorrect beliefs, impacting decision-making and public opinion across various topics.

Operating Systems (OS)

The OS is the software managing computer hardware and user interactions. It's essential for running other software and varies across devices (e.g., Windows for computers, Android/iOS for smartphones). Understanding OS helps in using various tech devices effectively.

Programs and Apps

Programs are software for specific tasks on computers, while apps (applications) are often simpler, user-friendly software for mobile devices and now also for computers.

Search Engines

Search engines, like Google or Bing, help find online information based on typed keywords. They differ from web browsers, which are tools for accessing the internet, including search engines.

Smart Home

Smart homes use interconnected devices for automated tasks, offering convenience and security. These include smart thermostats, doorbell cameras, and voice-activated assistants.

Streaming Media

Streaming media delivers real-time audio and video over the internet, like Netflix or Spotify. It offers instant access to content without full downloads.

Web Browsers

Web browsers are applications for accessing the internet and viewing web pages. They're essential for internet navigation, allowing activities like reading, watching videos, and online shopping. Users can choose and set default browsers.

Wi-Fi, Wireless Routers, and Hotspots

Wi-Fi uses radio waves for wireless internet connections. Wireless routers broadcast Wi-Fi in homes or offices, while hotspots offer public Wi-Fi access.
