Question 1
Value of currency started increasing which ultimately kick started __ (a. deflation / b. depreciation / c. disinflation) in economy.
Answer : a. deflation
Reason :Deflation is the term used to denote a fall in prices of goods indicating currency value rise.
Though disinflation could appear close in context, it actually means a slow rise in inflation rather than an exact opposite of inflation.

Question 2
The introduction of number zero to mathematics is considered to be one of the greatest __ (a. innovations / b. inventions / c. discoveries) of all times.
Answer: a. innovations
Reason : Innovation means a change that could be considered to have brought a great positive change in some field.
Hence innovation fits the context well. However, invention means to invent something new and discovery means to find something unknown.

Question 3
__ (a. incentives / b. bonuses /c. gifts) generally motivate people to carry out tasks in an efficient manner.
Answer: a. Incentives
Reason : Incentive means a motivating factor that encourages people to carry out their tasks efficiently.
Though bonuses and gifts closely suit the context, they generally mean only monetary benefits whereas incentive can mean even non monetary benefits like appreciation.

Question 4
___ (a. Idiom / b. Connotation /c. Paradox) refers to words implying different meaning than the actual literal meaning.
Answer : b. Connotation
Reason : Connotation is where words actually mean something but their implied meaning would be different. For example think of the words 'warm reception'.

Basic Technical questions

1)Find the output of the code snippet

   int i ;
   int v = scanf("%d",&i); // Lets say the input is 23
   printf("%d",v);

a)23
b)1
c)Junk

Anwer:

Output  = 1;
This is because, scanf reads and input and returns the number of items read.

 Hence 23 would be stored in i and 1 would be stored in v

2) Find the output of the code snippet

   char *S1 = "ABCD";
   char S2[ ] = "ABC";
   printf("%d,%d",sizeof(S1), sizeof(S2));

a) 3,4
b) 4,4
c) 3,3

Output: 4,4. 

S1 is a character pointer giving the size of the pointer variable.

 Second one is a character array with size 4. (Including the terminating character '\0' i.e Null Character ).

3) Consider there are two programs written respectively using two algorithms A and B. Say A has a complexity of n^2 and the other has a complexity of n/2. Given the same number of inputs which would take longer time to run.

Ans: 

First program written using algorithm A will take longer time. Higher the order of complexity, longer the time taken for execution.

4)What is the name of the type of constructor used to construct an object from another object where the desired parent class is same ?

ans:

Copy Constructor

5)Tell how function overloading saves programmer's efforts ?

Ans :

Function overloading, where different functions exist with the same name but different signatures plays its part in redundant function names when there more than one function performing logically the same operation but with different number and types of parameters as per the requirement. Hence the readability of the code is significantly improved.

6)Can you say few differences between Unicode character encoding and that of ASCII.

Ans:

Unicode uses 16 bits to encode characters and symbols whereas ASCII uses only 8 bits. Unicode has become a universal standard due to the fact that they can represent far great letters than ASCII. Unicode can be used hassle free to encode several regional languages other than English.

7)Differences between shared and exclusive locks ?

Ans:

Multiple transactions use shared locks during database read operations (SELECT Queries) as no data modification is involved. However if a transaction wants to change value of column/columns in single or multiple rows, it acquires an exclusive lock which will not be open to other transactions simultaneously.

8)In the context of memory management schemes, can you tell a primary difference between swapping and paging?

Ans:

Paging refers to writing and reading individual pages (fixed size) of a program to secondary memory (during program execution). Swapping refers to swap an entire program with another in secondary memory during heavy resource utilization.

9)Can you tell the primary difference between applets and conventional web applications ?

Ans:

Applet is a program that would be downloaded to browser and run on local CPU whereas web applications get executed on server.

Some Data Base Questions

1)Which of the following products was an early implementation of the relational model developed by E.F. Codd of IBM?

a) IDMS            b) DB2                C) dBase-II              D)R-Base

2) The following are components of a database except ________ .

A. user data B. metadata C. reports D. indexes

3)	The following are functions of a DBMS except ________ .
	A. creating and processing forms B. creating databases C. processing data D. administrating databases

4)Helping people keep track of things is the purpose of a(n) ________ .

A.	database	B.	table
C.	instance	D.	relationship

Quantitative Aptitude......

Important Things to know for solving Problems on Time and Work:

1. If A can do a piece of work in n days, then A’s 1 day work = 1/n

2. If A’s 1 day’s work = 1/n, then A can finish the work in n days.

Example: If A can do a piece of work in 4 days,then A’s 1 day’s work = 1/4. If A’s 1 day’s work = 1/5, then A can finish the work in 5 days

3. If A is thrice as good workman as B,then: Ratio of work done by A and B = 3:1. Ratio of time taken by A and B to finish a work = 1:3

4. Definition of Variation: The change in two different variables follow some definite rule. It said that the two variables vary directly or inversely. Its notation is X/Y = k, where k is called constant. This variation is called direct variation. XY = k. This variation is called inverse variation.

5. Some Pairs of Variables:

1. Number of workers and their wages. If the number of workers increases, their total wages increase. If the number of days reduced, there will be less work. If the number of days is increased, there will be more work. Therefore, here we have direct proportion or direct variation.
2. Number workers and days required to do a certain work is an example of inverse variation. If more men are employed, they will require fewer days and if there are less number of workers, more days are required.
3. There is an inverse proportion between the daily hours of a work and the days required. If the number of hours is increased, less number of days are required and if the number of hours is reduced, more days are required.

6. Some Important Tips:

More Men - Less Days and Conversely More Day - Less Men.


More Men - More Work and Conversely More Work - More Men.


More Days - More Work and Conversely More Work - More Days.


Number of days required to complete the given work = Total work/One day’s work.

Since the total work is assumed to be one(unit), the number of days required to complete the given work would be the reciprocal of one day’s work. Sometimes, the problems on time and work can be solved using the proportional rule ((man*days*hours)/work) in another situation.

7. If men is fixed,work is proportional to time. If work is fixed, then time is inversely proportional to men therefore,


(M1*T1/W1) = (M2*T2/W2)
