Networking Interview Questions and Answers
Question - 51 : - What are the functions of the typical server program?
Answer - 51 : - It waits for client-initiated requests. Executes many requests at the same time. Takes care of VIP clients first. Initiates and runs background task activity. Keeps running. Grown bigger and faster.
Question - 52 : - What is meant by Symmentric Multiprocessing (SMP)?
Answer - 52 : - It treats all processors as equal. Any processor can do the work of any other processor. Applications are divided into threads that can run concurrently on any available processor. Any processor in the pool can run the OS kernel and execute user-written threads.
Question - 53 : - What are General Middleware?
Answer - 53 : - It includes the communication stacks, distributed directories, authentication services, network time, RPC, Queuing services along with the network OS extensions such as the distributed file and print services.
Question - 54 : - What are Service-specific middleware?
Answer - 54 : - It is needed to accomplish a particular Client/Server type of services which includes:-
Database specific middleware
OLTP specific middleware
Groupware specific middleware
Object specific middleware
Internet specific middleware and
System management specific middleware.
Question - 55 : - What is meant by 3-Tier architecture?
Answer - 55 : - In 3-tier Client/Server systems, the application logic (or process) lives in the middle tier and it is separated from the data and the user interface. In theory, the 3-tier Client/Server systems are more scalable, robust and flexible.
Example: TP monitor, Web.
Question - 56 : - What is Load balancing?
Answer - 56 : - If the number of incoming clients requests exceeds the number of processes in a server class, the TP Monitor may dynamically start new ones and this is called Load balancing.
Question - 57 : - What are called Fat clients and Fat servers?
Answer - 57 : - If the bulk of the application runs on the Client side, then it is Fat clients. It is used for decision support and personal software.
If the bulk of the application runs on the Server side, then it is Fat servers. It tries to minimize network interchanges by creating more abstract levels of services.
Question - 58 : - What is meant by Horizontal scaling and Vertical scaling?
Answer - 58 : - Horizontal scaling means adding or removing client workstations with only a slight performance impact. Vertical scaling means migrating to a larger and faster server machine or multiservers.
Question - 59 : - What is Groupware server?
Answer - 59 : - Groupware addresses the management of semi-structured information such as text, image, mail, bulletin boards and the flow of work. These Client/Server systems have people in direct contact with other people.
Question - 60 : - What is a File server?
Answer - 60 : - File servers are useful for sharing files across a network. With a file server, the client passes requests for file records over nerwork to file server.
