BYOOS has been made possible thanks to the ability to create USB pen drives and other external storage devices with 'live' operating system images containing all the necessary drivers to allow boot up and operation on any compatible computer.
By allowing users to bring their own operating system there are significant cost savings to be made by organisations who commonly have many on-site users and are obliged to provide them with computer hardware to allow them to perform specific tasks as there is no longer a need to install a hard drive in each computer.
Upgrading and maintaining many PC computers has also become easier as companies only need to supply users with new pen drives containing the operating system boot images rather than having to re-image every PC with the latest build of the operating system thus eliminating upgrade costs.
As users can take the USB devices containing their version of the operating system around with them employees can boot up their home computer with the same USB stick so it has exactly the same software environment as they use in their place of work thus enabling employees to work at home exactly the same as they would in the office.
The introduction of cloud based storage, means portable operating systems are free of the need to store data locally.
