DAV Computer Class 8 Chapter 6 Problem Solving Question - Answer | Solutions | Notes

If you are looking for DAV Class 8 Computer Chapter 6 Problem Solving Solution then it is the right place to fulfill all needs related to the chapter. Sixth Chapter of DAV Class 8 Computer is Problem Solving.  Here I have covered all the questions and their answer, Fill in the Blanks and objective questions related to the chapter. I hope it well help you in your study.

A. Answer these following question.

a) What is Algorithm?

Ans. Step – by – Step method for solving any problem is called algorithm.

b) What is Flowchart?

Ans. A flowchart is a graphical representation of the problem solving process. It gives a step – by – step procedure for solving a problem.

c) Write the elements of a flowchart?

Ans. Various geometrical shaped represent the steps of the solution. The boxes are connected by directional arrows to show the flow of the solution.

Some geometrical shaped:-

• Ellipse:- Ellipse is used to indicate the start and end of a flowchart.

• Parallelogram:- A Parallelogram is used to read data (input) or print data (output).

• Rectangle:- A rectangle is used to show the processing.

• Diamond:- it used for decision making.

• Arrow:- Arrows are used to connect the steps in a flowchart.

• Connector:- Small circle are called connectors which are used for connecting different part of flowchart.

d) What is Assembly language?

Ans. The programming language that uses mnemonics for writing codes is called assembly language. Ex. LDA – for load, STA – for store, SUB – for subtract.

 e) Write the difference between Compiler and Interpreter. 

Ans.

          Compiler Interpreter

1. Compiler takes Entire               1.  Interpreter takes single

program as input                            instruction as input

2. Intermediate Object code  2. No Intermediate object 

is Generated                                  code is generated

3. More memory Requirement     3.  Less memory Requirement 

4. Program need not be               4. Every time higher level

compiled every time               program  is converted into 

                                                      lower level program  

 5. All errors are displayed after   5.  Errors are displayed for

entire program is checked             every instruction interpreted

Example: Compiler                once at a time

                                                             Example: Qbasic

f) What is object code?

Ans. The program written in HLL is called Source code and the program translated into machine code is called the object code.

g) Write about Compiler.

Ans. Language processor that translates the complete program as a whole in one go into machine code is called compiler.

B. Fill in the blanks.

a) A Flowchart is a graphical respresentation of the problem solving process.

b) Computer can understand only machine language.

c) In assembly language program written in mnemonic code.

d) Assembler converts an assembly language in machine language.

e) Compiler takes Entire program as input.

 C. True or False.

a) The program written in HLL is called source code. True

b) In Interpreter only one Error is displayed at a time. True

c) Compiler converts an assembly language into machine code. False

d) Computer understand only High level language. True

e) A flow chrt gives a step-by-step procedure for solving a problem.   True
