                             Second Year Computer Science Previous Questions Chapter wise ..

                                           Chapter 11. Advances of Computing

1. (a) The computing technology in which a problem is broken into pieces and solved concurrently is            called __________.

          Ans. Parallel Computing

    (b) Categorise the cloud service models.

            Cloud services are grouped into three – Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). 

 SaaS gives access to both resources and applications. Google Docs, Office365, facebook.com are examples. 

PaaS gives access to the components that we require to develop and operate applications on Internet. LAMP, ASP.NET, Google’s App Engine are some examples.

 IaaS provides basic storage and computing capabilities. Servers, networking equipments, data centre space etc. will be available as infrastructure where we can set up our software. Amazon Web Services, AT&T are some examples.

 Advantages: Cost savings; Flexibility; Reliability; Mobile accessibility.

 Disadvantages: Security and privacy; Lack of standard.

2. Define Robotics.

         : It is the scientific study associated with the design, fabrication, theory and application of robots. Robot is an electromechanical device which is capable of reacting to its environment and take autonomous decisions or actions to achieve a specific task. They are used in vehicle manufacturing industry, exploration of outer space, military, agriculture etc.

3. Give any three advantages and disadvantages of grid computing.

     1. Solves larger complex problems in short time.

      2.  Better use of existing hardware.

   3.  Easy to increase computing power by adding desktops or servers.

4. (a) A widely used operating system for cluster computers is _____.

        Ans. Linux

    (b) Discuss advantages of grid computing, cluster computing and cloud computing.

        Advantages of Grid computing :Solves larger complex problems in short time; Better use of existing hardware; Easy to increase computing power by adding desktops or servers.

    Advantages of Cluster computing :Reduces cost of processing; Failure of one system will not affect the processing; More components can be added.

   Advantages Cloud computing: Cost savings; Flexibility; Reliability; Mobile accessibility.

 5. NLP is ___________.

(a) National Level Programming

 (b) Natural Language Processing

(c) Neural Level Programming

(d) None of the above

    Ans. b

 6. What is ANN?

         Artificial Neural Networks (ANN) is the research in algorithmic modeling of biological neural system. It focuses on human brain that has the ability to perform tasks such as pattern matching, perception and body movements, and also the ability to learn, memorise, generalize etc. 

7. Write any two advantages of parallel computing compared to serial computing

       Serial Computing                                                              Parallel Computing

 (a) Single processor is used.                                                  (a) Multiple processors with shared memory.                                                                                          

                                                                                                 ( b) Instructions are executed concurrently

(b) Instructions are executed sequentially.
