10 Questions
What is the main advantage of a dual-core design?
It enables parallel execution of instructions, potentially doubling performance.
In a multicore system, what is the primary difference compared to a multiprocessor system?
Multicore systems have multiple processors on a single chip, while multiprocessor systems have separate chips.
What is the primary purpose of a clustered system?
To provide high availability and fault tolerance by having redundant nodes.
In an asymmetric clustering system, what is the role of the hot standby node?
It is a backup node that takes over if one of the active nodes fails.
What is the primary advantage of a multiprocessor or multicore system over a single processor system?
Enhanced performance by enabling parallel execution of instructions.
In the context of operating systems, what is the purpose of dual-mode operation?
To separate privileged kernel mode from user mode for security and stability.
What is the primary role of a distributed lock manager (DLM) in a clustered system?
To avoid conflicting operations by managing locks on shared resources.
What is the purpose of a storage area network (SAN) in a clustered system?
To provide shared storage that can be accessed by multiple nodes in the cluster.
What is the difference between symmetric and asymmetric clustering?
Symmetric clustering has all nodes running applications, while asymmetric clustering has a hot standby node.
What is the role of interrupts in a multiprogrammed system?
To allow the operating system to regain control from user programs.
Test your knowledge on memory management in multiprogramming systems, where multiple jobs can be kept in main memory simultaneously. Explore topics such as multitasking, thread execution, memory layout, and operating system operations.
