Fun-dih-mentals
This part of the OS is always present in memory to interface hardware and software; rhyming with Colonel.
What is Kernel?
In a directed graph used to model system resources, this geometric shape is used to represent a process.
What is a Circle?
This algorithms stops deadlock in CPU processes but also stops banks from lending too much money.
What is Banker's Algorithm?
This foundational case occurs when two concurrent programs each successfully open and lock a single file for their execution duration, while indefinitely stalling for the file held by the other.
What are Deadlocks on File Requests?
(v.) Technique of flattening your tongue against the roof of your mouth; supposedly improving jawline and face shape.
What is Mewing?
Either after being in death row or being loaded into memory can a program become this.
What is Process?
This computer scientist is credited with publishing the visual directed graph method used for modeling system deadlocks back in 1972.
Who is Richard Holt?
Excess greed causes deadlock, but sloth produces this since the CPU procrastinates on dealing with these low-priority processes.
What is Starvation?
During a disk-sharing livelock, the competing processes remain completely active rather than blocked. What restless, active form of waiting are they trapped in?
What is Busy-Waiting?
(n.) Internet character showing a head sticking out of a bathroom appliance.
What is Skibidi Toilet?
Press 'F' or move the mouse 5cm; each of these actions triggers this, causing the CPU to temporarily suspend the current process.
What are Interrupts or I/O Events?
This necessary condition for a deadlock means the operating system cannot temporarily take a resource away; the process holding it must release it voluntarily.
What is "No Preemption"?
In the Dining Philosophers problem, this technique ensures no philosopher starves; not by giving everyone more forks, but by making the hungriest ones jump the line.
What is Aging?
This type of deadlock occurs when two users try to update the exact same bank account or row at the same time, freezing both until the system cancels one of them.
What is Deadlock on Databases?
(suffix) Internet slang that means to optimize or maximize a particular quality or activity; obsessive self-improvement.
What is (-maxxing)?
This smallest unit of storage on a hard drive is typically 512 bytes or 4K bytes, and is read or written in a single operation.
What are Data Sectors?
In deadlock modeling, if you see a solid arrow pointing from a square directly to a circle, it indicates this specific relationship between the resource and the process.
What is "allocated" (or "holding")?
This is term used for the process or resource being sacrificed in a deadlock to resolve it.
What is Victim?
This architectural deadlock happens when a temporary disk storage allocation zone fills up completely with incomplete outputs from multiple jobs, preventing any single job from finishing its print transmission to free up room.
What is Deadlock in Spooling?
(n.) Internet nickname where a fictional orange fruit complains that its name is uncreative because it's just named after its color, demanding for a more thought-out name.
Who is Sharmaine?
This attentive OS must-have holds PCBs and keeps CPU scheduling, but sometimes the other half has either BB or banana.
Ready queue
Rather than being an independent rule, this condition is the direct consequence of the other three combining; resulting in a specific impasse where every single involved process is trapped relying on another to voluntarily surrender its held asset before anyone can proceed.
What is circular wait?
This synchronization bug occurs when two processes access shared data concurrently, and the final outcome depends on which one finishes first.
What is a Race Condition?
Happens when a hard drive head is constantly pulled back and forth between two programs' requests, keeping the system 100% busy but getting zero real work done.
What is Livelock on Disk Sharing?
(quote) Viral internet meme in 2021 where famous wrestler and actor John Cena is eating ice cream in his car while promoting the movie Fast and Furious.
What is "Xiàn zài wo you (bing chilling) Wo hěn xi huān (bing chilling) Dàn shì sù dù yu jī qíng jiu bi (bing chilling)"?
