It provides interaction between users of computers and computer hardware. Write difference between micro kernel and monolithic kernel? What is SMP (Symmetric Multiprocessing)? What is Context Switching? What are various sections of the process? What is a deadlock in OS? What are the necessary conditions for a deadlock? What do you mean by Belady’s Anomaly? What is starvation and aging in OS? What is Reentrancy? What is the difference between paging and segmentation? What is a zombie process in Linux OS? OOPS Object-oriented programming – As the name suggests uses objects in programming. Object-oriented programming aims to implement real-world entities like inheritance, hiding, polymorphism, etc. in programming. What is meant by Structured Programming? What are the main features of OOPs? What is encapsulation? What is Polymorphism? What is Compile time Polymorphism and how is it different from Runtime Polymorphism? What is Abstraction? What is a constructor? What is meant by static polymorphism? What is the difference between overloading and overriding? What is meant by exception handling? Computer Networks A computer network is a collection of computers or devices connected to share resources. Any device which can share or receive the data is called a Node What do you understand by DNS? What is a peer-to-peer process? Tell me something about VPN (Virtual Private Network) What is a ‘frame relay’, and which layer does it operate? What are the different features of Frame Relay? Differentiate between ‘attenuation’, ‘distortion’, and ‘noise’. Mention the uses of the Hamming code. What are proxy servers, and how do they protect computer networks? What are nodes and links? Why is encryption on a network necessary? Like Article Suggest improvement Next UBS Interview Experience (On-Campus) Share your thoughts in the comments Add Your Comment Please Login to comment...
