A. Fill in the blanks:
1. An algorithm is a set of sequential steps that are developed in solving any problem.
2. The start/stop box symbol represents the starting or ending point of a program.
3. The processing box is used for writing the processing instructions.
4. The input/output box is used to display input and output of a program.
5. The decision box represents all comparisons and decisions.
6. The connectors are used to connect one part of flowchart to another.

B. State True or False:
1. A flowchart is not a pictorial representation of steps to get the solution of a problem. (False)

b) Flowchart
c) None
Answer: b) Flowchart

E. Answer the following:
1. Define the term flowchart.
Answer: A flowchart is a pictorial representation of steps or an algorithm used for solving a particular problem.

2. What is an Algorithm?
Answer: Algorithm is a set of sequential steps to solve any logical or a mathematical problem. An algorithm is written in a simple language.

3. What is the use of Input/Output box?
Answer: Input/Output box is used for accepting input or giving output of the program.

4. When do we use the Process box?
Answer: Process box is used for writing the processing instructions and doing calculations.

5. What is the use of the Decision box?
Answer: Decision box is used for checking or applying any condition in the program.

6. Write the difference between Flowchart and Algorithm.
Answer:
Flowchart
→ A flowchart is a pictorial representation of steps or an algorithm used for solving a particular problem.
→ To create a flowchart, different boxes are used which are connected to each other with the help of flow lines.
Algorithm
→ Algorithm is a set of sequential steps to solve any logical or a mathematical problem.
→ Algorithm is always written in simple language and precise manner so that anyone can understand the steps.
