What Does Unrecoverable Error Mean?

Techopedia Explains Unrecoverable Error

Unrecoverable errors are usually caused by of programs or applications that run in user-mode on a computer. User-mode run processes are not given direct access to the memory, rather they use a virtual space assigned to them by the system. Since they are basically isolated from direct access to memory, they do not interfere with the resources and hence do not compromise of the integrity of a system. But at the same time they are at a huge potential to cause an unrecoverable error if they try to read or write anything from the system memory. This causes an exception call and the whole system either freezes or reboots.
