Sample CS6401 important questions:
1. What is meant by Mainframe Systems?
Mainframe systems are the first computers developed to tackle many commercial and scientific applications. These systems are developed from the batch systems and then multiprogramming system and finally time sharing systems.
2. What is meant by Batch Systems?
In this, operators batched together jobs with similar needs and ran through the computer as a group .The operators would sort programs into batches with similar requirements and as system become available, it would run each batch.
3. What is meant by Multiprogramming?
Several users simultaneously compete for system resources (i.e) the job currently waiting for I/O will yield the CPU to another job which is ready to do calculations, if another job is waiting. Thus it increases CPU utilization and system throughput.
4. What is meant by Time-sharing Systems?
Time Sharing is a logical extension of multiprogramming .Here, CPU executes multiple jobs by switching among them, but the switches occur so frequently that the users can interact with each program while it is running.
5. What are the Components of a Computer System?
- Application Programs
- System Program
- Operating System
- Computer Hardware
6. What are the advantages of Multiprogramming?
- Increased System Throughput
- Increased CPU utilization
7. What are Multiprocessor System?
Multiprocessor systems have systems more than one processor for communication, sharing the computer bus, the memory, clock & peripheral devices.
8. What are the advantages of multiprocessors?
- Increased throughput
- Economy of scale
- Increased reliability
