Think of it like a club with a max capacity of 10 people, where some people have VIP cards. If a person with a VIP card wants to get into the club, the bouncer will kick out one of the people inside that doesn’t have a VIP card to make space for them.
For a more technical explanation:
There are several processors on computers and each can be in use by 1 process at a time. Different processes can get different amounts of time based on their priority (called niceness in Linux) and they’ll be removed from the processor once their time is up until their next share of time.
On a real-time kernel some processes are marked as real-time (certain range of niceness values, can’t remember the exact range). If a process that is real-time says it needs some processor time, a process that isn’t real-time that’s currently running will be immediately ripped off the processor to make room for the real-time process.
It was a survey measuring a bunch of things, not sure why that was the metric they focused on for the headline though.
"Since the start of the pandemic, grocery prices have risen 25%, the report also found.
Some consumers have had to sacrifice necessities to afford food, the personal finance company found.
That includes 28% who sacrificed other needs like rent or bills to pay for groceries, and 27% who occasionally skipped meals. Additionally, 18% have either applied for or considered applying for food stamps, while 15% rely on or have considered turning to food banks.
Yet, 53% indicated they earn too much to qualify for food stamps or other government assistance but still have difficulties paying for necessities.
While most consumers report noticing higher grocery costs,51% have also seen increases in gasoline prices; 39% said other bills like cable, electricity and internet have spiked; 27% said housing costs have gone up; and another 27% said dining out costs have risen."
