![]() WebKit was the original rendering engine, but Google eventually forked it to create the Blink engine all Chrome variants except iOS used Blink as of 2017. Most of Chrome's source code comes from Google's free and open-source software project Chromium, but Chrome is licensed as proprietary freeware. The browser is also the main component of ChromeOS, where it serves as the platform for web applications. Versions were later released for Linux, macOS, iOS, and also for Android, where it is the default browser. It was first released in 2008 for Microsoft Windows, built with free software components from Apple WebKit and Mozilla Firefox. Google Chrome is a cross-platform web browser developed by Google. ![]() Proprietary freeware, based on open source components The alternative is higher infrastructure costs or to deny students access to powerful extension/Apps because of download requirements.Beta / September 2, 2008 14 years ago ( )ġ.0 / December 11, 2008 14 years ago ( ) This would identify that machine as being configured for those students such that their extensions/Apps are immediately available at no bandwidth cost. While not addressing all situations, there is a simple solution that costs virtually nothing - a piece of masking tape with one or more student student names on each Chromebook. As more and more Apps become available in education, the problem will simply grow. ![]() Given that a student may use many extensions/Apps (more if they use their account from home) that utilize synched data, a huge bandwidth demand can arise (e.g., at the start of every class) with random Chromebook use that can slow downloading to potentially several minutes while increasing infrastructure requirements. Further, some schools wipe out all student profiles on a Chromebook on a regular (say 30-day) basis. If they have never used that particular Chromebook before, they must create a new user profile at which point all of their extensions/Apps will be automatically downloaded. The problemĪ problem arises when a classroom has a stack of Chromebooks (usually in a charging station) and students randomly grab one at the beginning of a class. There are many advantages for such Apps, which can also run on a PC or Mac desktop. ![]() (Note that the initial size of an extension/App has no bearing on subsequent bandwidth needs.) Some new Apps are " Chrome Packaged Apps" that are downloaded and function offline in much the same way as a desktop application. While many extensions and Apps are relatively small and only point to web pages, developers are creating larger and more powerful extensions/Apps. This means that every student will have all of their extensions and Apps downloaded when logging in for the first time. Unlike desktop solutions on a PC or Mac, Chrome extensions/Apps are not shared across student user profiles. ![]() Beyond ongoing Internet usage, schools must consider the costs associated with the downloading of Chrome extensions/Apps into student profiles on a Chromebook. At a school district level, with tens or hundreds of thousands of students, such costs are non-trivial. The adaptation of Chromebooks in Education comes at a cost of greatly expanded network infrastructure and unsatisfactory connectivity in many cases. ![]()
