Operating System structure

What is the main characteristic of a monolithic system's OS kernel?

• Divided into layers

• Bundled in one large binary file

• Utilizes concentric rings

How does an exokernel prevent conflicts among virtual machines?

• By running a separate OS for each user-level virtual machine

• By using concentric rings for protection

• By efficiently managing resources

What distinguishes virtual machines from other approaches in terms of OS diversity?

• They use concentric rings for protection

• They support various operating systems

• They have a unified binary file for the entire OS

What is the main role of MINIX 3's microkernel?

• Managing resource allocation

• Facilitating inter-process communication

• Handling device drivers independently

What approach does THE System use for organizing OS functions?

• Multilayered approach

• Microkernel approach

• Monolithic structure

In a microkernel approach, how does it enhance reliability?

• Bundles all services in one binary file

• Breaks the OS into small modules

• Uses concentric rings for protection

What is the main advantage of a monolithic system in terms of performance?

• High performance via direct kernel calls

• Enhanced reliability by breaking the OS into small modules

• Improved stability due to resource division

When was THE System developed, and what computer did it run on?

• 1975, IBM System/360

• 1968, Electrologica X8

• 1980, DEC PDP-11

What is the disadvantage of a monolithic system in terms of security?

• User-level process failures can crash the system

• Resource conflicts among virtual machines

• Lack of clear kernel-user process divide

What is the primary function of an exokernel at the kernel level?

• Managing resource allocation

• Dividing resources among virtual machines

• Bundling all OS functions in one binary file
