BIM Operating Systems Review

Why is the kernel a core component?

• It's the brain of the operating system

• It's in the core of the hardware

• It manages the hardware

• It manages the software

Why is the kernel a hardware manager?

• It manages all the thing inside the computer (processor, memory, hard drive, and more)

• It manages your I/O (input/output) controls like your keyboard and screen

• It manages your software

• It keeps your hardware from breaking

Why is the kernel a bridge?

• It's a bridge between your software (apps) and hardware (physical parts)

• It's bridge shaped in your hardware

• It bridges the gap between your keyboard and screen

• It actually the Golden Gate Bridge

Why is the kernel a process handler?

• It keeps track of the running programs and makes sure they all get to use the computer's resources

• It makes sure the processes don't glitch

• It makes sure processes reach the hardware

• It starts and stops processes

Why is the kernel a memory manager?

• It decides which part of your computer's memory is used for what so everything goes smoothly

• It manages memory files that you've dumped in the trash

• It erases memory

• It alerts you when your memory is filling up

Why is the kernel a security guard?

• It makes sure only authorized things access your computer; it keeps your computer safe

• It serves as an antivirus

• It reviews your password to make sure it's safe

• It keeps you away from inappropriate websites on school-issued technology

Why is the kernel an interrupt handler?

• The kernel is an interrupt handler because it stops what it's doing and deals with whatever command it sees (like a mouse click or key press)

• The kernel is an interrupt handler because it manages the computer's memory.
• The kernel is an interrupt handler because it controls the computer's CPU.
• The kernel is an interrupt handler because it runs the computer's applications.

Why is the kernel a traffic cop?

• The kernel is a traffic cop because it manages the flow of data between your apps and the hardware

• The kernel is a traffic cop because it controls the traffic lights
• The kernel is a traffic cop because it issues traffic tickets
• The kernel is a traffic cop because it directs traffic

Why is the kernel a hidden hero?

• Because it works in the background to keep the computer running; you don't see it though

• Because it is the largest part of the operating system
• Because it is the only part of the system that interacts with the hardware
• Because it is the only part of the system that the user interacts with

Why is the kernel critical for stability?

• If your kernel crashes, then the whole computer crashes; it's crucial for the reliability and safety of your computer

• It provides a user interface
• It runs applications
• It provides internet connectivity
