Bond Issue
Education bonds are voter-approved funds that can only be used for school facilities. Districts collect this money by taxing property owners on the assessed value of their properties. Districts sell the bond to investors. The local bond is similar to a loan. It is much like a home equity line, but for the school district.

Broadband
Broadband Internet is a speed benchmark set and updated by the Federal Communications Commission. The benchmark was last updated in 2015 to define broadband as 25 Mbps download speeds and 3 Mbps upload speeds. “Broadband” is generally shorthand for quality Internet service. Broadband provides high speed Internet access via multiple types of technologies, including fiber-optics, wireless, cable, DSL, and satellite.

Dark Fiber
Unused fiber-optic infrastructure that has not been “lit” with Internet service. When someone is building a fiber-optic network, the cost of adding more fiber-optic than is immediately required is negligible and the cost of having to add more fiber-optic later is very high. Therefore, many include dark fiber-optic in projects. These fibers that can be leased to others or held in reserve for a future need.

Digital Redlining

The practice of creating and perpetuating inequities between already marginalized groups specifically through the use of digital technologies, digital content, and the internet. For example, ISPs invest in building fiber infrastructure in wealthier neighborhoods, while under-investing in the broadband infrastructure in low-income communities resulting in low-income broadband users with more expensive, slower access.

Digital Subscriber Line (DSL)
Internet access offered over phone lines that allows users to use the Internet at speeds greater than dial-up while also using the phone line for telephone conversations. DSL uses frequencies not used by human voices. Unfortunately, these frequencies degrade quickly over distance, meaning customers must live within a mile or even much closer to the central office to get the fastest speeds. Upstream speeds over DSL tend to top out at 5 Mbps.

Fiber-optic
A system that uses glass (or plastic) to carry light, which is used to transmit information. Typically, each side of the fiber is attached to a laser that sends the light signals. When the connection reaches capacity, the lasers may be upgraded to send much more information along the same strand of fiber. This technology has been used for decades and will remain the dominant method of transmitting information for the foreseeable future.

Homework Gap
The homework gap is a term used to describe the inequities between students who have devices and internet connectivity at home, and those who don’t and, as a result, struggle to complete schoolwork at home.


Hotspots
Wi-Fi Hotspots are physical locations, such as an airport or coffee shop, where people can wirelessly connect their device(s) to the Internet using Wi-Fi via a wireless local area network (WLAN). A mobile or portable hotspot uses the smartphone’s data connection to connect or “tether” their device(s) to the Internet.


Hybrid Learning
Hybrid learning occurs when a student uses both in-class and online instruction to learn course material.


Internet Service Provider (ISP)
An organization that provides services for accessing or using the Internet.


Joint Powers Authority (JPA)
An entity permitted under the laws of some U.S. states (e.g. California), whereby two or more public authorities (e.g. local governments, or utility or transport districts), not necessarily located in the same state, may jointly exercise any power common to all of them. By combining their commercial efforts, public authorities can achieve economies of scale or market power. For example, National IPA is a purchasing consortium of local government and education agencies.
