What is Data Mining?

In simple words, the process of analyzing and extracting data from data set and transforming those data into understandable form for future use is known as data mining. From huge databases, we summarize data,  discover the patterns or correlations among the various fields in large relational database.

Questions Answers of Computer Organization (Short Questions Set- II)

 

Questions Answers of Computer Organization BIM Set – II

1)     Define the term delayed load.

Ans : Compiler detects the data conflict and reorder the instructions to delay the loading of conflicting data by inserting a no operation instruction. This method is referred as delayed load.

2)    List the functions of I/O Interface.

Ans : The functions of I/O Interface are listed below:

a)     Helps in communication between the CPU and I/O devices.

b)    Receives the data from a system/data and transfer it to the another system.

c)     Helps in communication between the information system.

3)    What is the main cause of data hazard?

Ans : The main cause of data hazard is unavailability of operand i.e. error in instruction since pipeline is instruction dependent.

4)    Differentiate between DMA and I/O processor.

Ans :

DMA

No.

I/O Processor

It is the data transfer technique between faster storage devices, where CPU is removed from the path for a certain period of time so as to increase the speed of the transfer.

01

It is the processor which controls the transfer of information between computer’s main memory and other essential equipments including CPU.

5)    Perform 2’s complement addition of (-5)10  + (-9)10  in 8 bit format..

Ans :  Solution,

-5 = 2’s complement of 5 =11111011

-9 = 2’s complement of 9 = 11110111

Now,

11111011

+11110111

_________________

1 11110010

(Note : The left most bit is the signed bit.)

Now, converting it into 2’s complement we get -00001110 = -14

6)    Draw the graphical symbol of X-NOR gate with its algebraic function and truth table.

Truth table of X – NOR
A B Z
0 0 1
0 1 0
1 0 0
1 1 1

Ans :

7)    Define effective address.

Ans : Effective address can be defined to be the address of the operand in computational – type instructions or the target address in the branch – type instructions.

8)    List the services provided by Operating System.

Ans :  The services provided by Operating System are listed below :

a)    Manages the use of main memory.

b)    Protects the hardware and software

c)     Control the hardware resources

d)    Access to input output devices

e)    Controlled access to files

f)      System access

g)    Error detection and response

9)    Differentiate SRAM and DRAM

Ans :

SRAM

No.

DRAM

Does not need to be periodically refreshed.

1.

Needs to be periodically refreshed.
Expensive

2.

Cheaper
Consumes more power

3.

Consumes less power
Provides low density.

4.

Provides high density.
Comparatively high speed

5.

Comparatively low speed.
Static mode

6.

Dynamic mode.

10)           List any five data transfer instructions.

Ans : Any five data transfer instructions are listed below :

a)    Load         LD

b)    Store        ST

c)     Move       MOVE

d)    Push         PUSH

e)    Pop           POP

(Note : Data transfer instructions cause transfer of data from one location to another without changing the binary information content. )
