| Software | Strings of programming code that are run and processed by the hardware components of the computer system |
| 3 Major Operating Systems | Microsoft, Apple, Linux |
| Microsoft | Windows Operating System |
| Apple | iOS and OS-X operating systems |
| Linux | is used as a baseline in many systems like Roku TVs, social media feeds, and smart technology integrated into the automotive industry |
| What are the main determining factors when choosing an operating system to fit the needs of a virtual coaching business? | 1) Budget, 2) Intended use, such as added video editing, 3)Ease of use, with peripherals like tablets or wearable fitness trackers, 4) Preference, user experience, and interface, 5) Hardware |
| Video conferencing technology | is a critical channel of communication for virtual training. |
| Humans process ________ information more quickly and capably than through audible or written information | visual |
| What can result in higher perceived friendliness and improved information recall during video calls? | Regular eye contact |
| What percentage does body language contribute to effective communication? | 55% |
| What percentage does tone of voice contribute to effective communication? | 38% |
| What percentage do words on a phone call or written notes contribute to effective communication? | 7% |
| What factors should be considered when choosing a video conferencing software? | 1) price, 2) participant and meeting time thresholds, 3) mobile app accompaniment, and 4) other features such as meeting recording |
| Examples of video conferencing software | Zoom, Web-Ex, Google Meet, Microsoft Teams |
| Word Processing Software | It can also be used for record keeping and business administration activities such as scheduling and invoicing. |
| Examples of Word Processing Software | Microsoft Word, Apple Pages, Google Docs |
| Spreadsheets | Allow the fitness professional to create workout programs, invoice clients, or build client metric monitoring sheets, among many other uses |
| Examples of Spreadsheets | Microsoft Excel, Apple Numbers, Google Sheets |
| Bandwidth | The maximum data transfer rate of a network or Internet connection, in a specific amount of time, or how fast Information can be downloaded or uploaded to and from the Internet. |
| How is bandwidth measured? | megabytes per second or Mbps |
| Megabytes | A measurement of data, 1,000 kilobytes. Megabytes can be broken down into kilobytes (kbit) |
| Kilobytes | A measurement of data, 1,000 bits |
| Gigabyte | 1,000 megabytes (Mb) |
| What is the fastest bandwidth for internet connections? | Broadband Internet connections such as DSL, fiber optics, and cable Internet will be the fastest, most reliable, and often cheapest Internet connections to choose from. |
| How fast are broadband internet connections? | bandwidth speeds from 25 Mbps to 1,000+ Mbps |
| Recommended bandwidth speed for virtual coaching | broadband internet connections that provide 25 to 75 Mbps of bandwidth |
| Why should you run an "Internet Speed Test"? | To test your current internet speed. If it is running less than 25 Mbps, it may be time for you to upgrade your Internet package or Internet service provider. |
| Examples of Computer Peripherals | Lighting, Cameras, Microphones |
| What are the main factors to consider when purchasing lighting peripherals? | 1) Lighting Spectrum and 2)Budget and Portability |
| Lighting Spectrum | color temperature; what hue of color is being provided by a light source |
| How is the degree of light measured | Degrees of Kelvin (K); Kelvin is measured from 1,000 K up to 10,000 K. The lower end of the Kelvin spectrum has a far-red tinge to it. The high end of the Kelvin spectrum has a blue overtone. |
| What is the typical lighting spectrums used in video content ? | between 3,200 K and 5,500 K. |
| Indoor lighting and indoor scenes require how much lighting spectrum? | 3,200 K lighting spectrum; it will be warmer in color with a higher degree of orange or yellow. |
| Midday daylight requires how much lighting spectrum? | 5,500 K lighting spectrum; it will be a cooler light that is mostly bluish-white |
| What does too low of lighting produce? | more flat colors and may create unnatural skin tone |
| What does too high of lighting produce? | lack warmth and be harsh to look at |
| When is 5,600 K spectrum more optimal for use? | where there is a lower level of light or in indoor settings where incandescent bulbs or soft, warm lighting may be used. The midday lighting spectrum will help produce a brighter, more natural and balanced feel. |
| When is the warmer 3,200 K spectrum more optimal for use? | where there is harsh white light such as under fluorescent bulbs or when filming in brightly lit locations. The warmer spectrum may reduce the harsh look that higher spectrum lighting may produce. |
| What are possible consideration when deciding on a camera? | 1) Megapixel (MP) rating of the camera, 2) Video recording resolution, 3) Budget |
| Pixel | The smallest portion of an image. They are tiny little dots or squares of color that, when put together, make up an image. |
| Megapixel | 1 million pixels put together, a measure of image resolution or graphic resolution. |
| The more megapixels in an image, the more _______ and _______an image will have | detail and clarity |
| Video Resolution | another representation of image quality; relates to how many pixels the video image has both in horizontal count and vertical count. |
| The higher the video resolution, the _____ the video quality. | higher |
| What are the most common resolutions for video content? | 720p (High Definition), 1080p (Full High-Definition), and 4K ultra HD (Ultra High-Definition) |
| What is the minimum requirement for video resolution? | 1080p full HD video resolution |
| DSLR camera | Professional quality photos, typically films video in HD, higher price point, and may need to buy attachments |
| Hand-held digital camera | Lower-quality but hand-held, no additional lenses needed, and reasonably priced |
| Smartphone camera | Newer phones will have all of the features needed to produce high-quality video and images Getting Technical |
| Dynamic microphones | are the types of microphones one might see being used by a singer or comedian performing on stage; contain a coil and magnet inside that are sensitive to sound vibrations; do better in environments that have a higher level of background noises. |
| Condenser microphones | do not contain a coil and magnet; instead use capacitor plates; more sensitive to smaller sound vibrations than a dynamic microphone. This can help pick up the subtle differences in a voice and may be better for recording a podcast in a quiet area. |
| USB microphone | will plug right into the computer; is simple and considered plug and play, with no additional software, drivers, or expensive audio interface systems |
| XLR microphone | will need an audio interface between the computer and the microphone; can become more expensive due to both initial purchase of the microphone and required add-ons needed to operate; will produce a higher-quality sound than a USB microphone |
| Energy Expenditure | The number of calories burned over a specified period of time at a given intensity of movement. |
| Total daily energy expenditure (TDEE) | The number of calories a person burns over a 24-hr period. |
| Non-exercise activity thermogenesis (NEAT) | The measurement of energy expenditure from all other movements outside of intentional exercise activity. |
| Approximately when were the first wearable fitness trackers introduced? | 1981 |
