COMPUTING AND INFORMATICS S 07

1.With reference to object oriented programming (OOP), discuss the terms (i) encapsulation, and (ii) abstraction (S07 2+2 M)
2.Differentiate ranging from (i) Function overloading, and (ii) function overriding. (S07 2+2 M)
3.Write a C++ program which will determine whether an input number is prime or not? (S07 6M)
4.A phone number, such as (212) 767-8900, can be thought of as having 3 parts: the area code (212), the exchange (767), and the number (8900). Write a C++ program that uses structure to store these 3 parts of a phone number separately. Call the strucuture phone. Create 2 structure variables if kind phone. Initialize one, and have the user input a number for the other one. Then display both numbers. The interchange might look like this: Enter your area code, exchange and number: 415 555 1212 My number is (212) 768-8900 Your number is (415) 555-1212. (S07 6M)
5.Write a swap () function which exchanges 2 floating point values of x and y. Test this function for a= 22.2 and b=44.4 as input and write down the corresponding output.(S07 6M)
6.Write a program that reads five numbers in an array and then print them in reverse order. The numbers are floating point values. (S07 6M)
7. What is meant by the term ‘system’? elaborate the characteristics and categories of info system? Briefly explain them (S07 8M)
8.With reference to ISO/OSI model, discuss subsequent terms: (i) Entity, (ii) Protocol (iii)ISP, (iv) Message (S07 two × 4M)
9.A LAN network using CSMA/CD has a bandwidth of 10 Mbps. If the maximum propagation time (including the delays) is 25.6 µsec, what is the minimum size of the frame? (S07 four M)
10.What is LAN? What is IEEE standards for LAN? define them briefly with a neat diagram. (S07 8M)
11.What is email? describe and briefly discuss the terms: (i) Mail box, (ii) user agent, and (iii)Message transfer agents, in relation to email services (S07 2×4M)
12.What is meant by process-to-process delivery in transport layer? How can this be achieved through client-server technology? (S07 6M)
13.What is TCP/IP protocol suite? How many layers are there in TCP/IP? Draw a neat diagram and briefly define them. (S07 6M)
14.Convert the subsequent from 1 number system to another: (i) (1357)10 = ( )2 (ii) (1463)10 = ( )8 (iii) (1010010110)2 = ( )16 (iv) (573)8 = ( )16 (v) (1100100110)2 = ( )8 (S07 two × 5M)
15.Explain briefly the following: (i) Object program (ii) Use of BIOS (iii) Interpreter (S07 two ×3 M)
