Answer
1) Answer the following questions (14)
a) What is an algorithm? (1)
Answer – An algorithm is a collection or set of step-by-step instructions to perform a specific task or solve a problem.
b) What is sequence? (1)
Answer – Sequence is the particular order by which instructions are followed or performed in an algorithm.
c) How algorithm and Sequence can help a student? (2)
Answer – Learning the process of making an algorithm and sequence can help a student to develop a strong foundation in
Logical thinking
Problem solving.
d) What is abstraction? How it can help a student? (3)
Answer – Abstraction means that one individualfocuses on important things and ignore the rest.
Abstraction can help a student to learn to identify the important details in solving a problem.
e) How branching statement can help a student? (3)
Answer –
The knowledge of branching statement can not only help a student in variety of academic areas but also in real-life situations.
This enables the student to grasp the concept of cause and effect of that.
f) What is bugs? (1)
Answer – Bugs are the mistakes made during writing an algorithm.
g) What is debugging? How it can help a student? (3)
Answer –Debugging is the process by which bugs are found andc corrected to make the algorithm work properly.
Learning the process of debugging can help a student to become a better coder and problem solver.
