What is the main characteristic of a monolithic architecture?

• Multiple layers of components

• Modular design

• All components are contained in the kernel

• Separation of user and kernel space

Which of the following is an example of a layered operating system?

• Windows XP

• Linux Mint

• VMS

• OS/360

What is a key advantage of a microkernel architecture?

• High performance

• Direct communication with hardware

• Modularity and easy modifications

• Single binary file

Which operating system is known for using a microkernel?

• Mach

• Linux

• Windows 2000

• OS/360

What is a primary disadvantage of monolithic architecture?

• Easy to modify

• Low performance

• Difficult to isolate bugs

• High modularity

In a layered architecture, how do layers communicate?

• Only with adjacent layers

• Through the kernel

• Using shared memory

• Directly with all other layers

What is a characteristic of networked and distributed operating systems?

• Single user access

• No network capabilities

• Resource sharing across independent computers

• Monolithic structure

Which of the following is NOT a strength of layered architecture?

• High performance

• Modularity

• Flexibility

• Simplicity

What does a clustered system primarily aim to provide?

• High performance

• Low cost

• Single point of failure

• High availability

Which of the following describes a multiprocessor system?

• Is less reliable than single-processor systems

• Contains only one processor

• Can execute multiple programs simultaneously

• Uses a single bus for communication
