Novell Interview Questions and Answers

Device drivers are software that allow the operating system to communicate with hardware devices. Streams drivers are a type of device driver that use the streams framework in Unix-like operating systems.

• Streams drivers in Unix-like operating systems follow a specific structure defined by the streams framework.

• They consist of modules that handle different aspects of data transfer between the device and the operating sy...read more

Enforcing consistency of data structures in a multiuser environment requires implementing strict validation rules and utilizing database transactions.

• Implement strict validation rules to ensure data entered by users conforms to the required structure.

• Utilize database transactions to ensure that changes to the data structures are atomic and consistent.

• Use locking mechanisms to prevent concurrent access and modification

The time taken for a packet of size to travel in an ethernet depends on various factors.

• The time taken for a packet to travel in an ethernet network is influenced by factors such as network congestion, distance between sender and receiver, and the speed of the network.

• For example, a small packet may take microseconds to travel within a local network, while a larger packet may take milliseconds to reach its destination.

List of process calls generated in Unix from creation to termination

• Fork: Creates a new process by duplicating the existing process

• Exec: Replaces the current process image with a new one

• Wait: Parent process waits for the child process to terminate

• Exit: Terminates the process

• Kill: Sends a signal to a process to terminate it

Fork and exec are implemented as two different calls to allow for flexibility and efficiency in process creation and execution.

• Fork creates a new process by duplicating the existing process, including its memory and resources.

• Exec replaces the current process with a new program, loading it into the current process's memory space.

• Separating fork and exec allows for more control over the creation and execution of process...read more

Repeater, Bridge, Router, and Gateway are network devices that operate at different layers of the OSI model. An adaptive learning bridge is a bridge that uses machine learning algorithms to optimize network performance.

• Repeater: Operates at the physical layer of the OSI model, regenerates incoming signal to extend the network's reach.

• Bridge: Operates at the data link layer, connects two different network segments and f...read more
