4. What type of device is computer printer?

a) Memory
b) Output
c) Storage
d) Input
✅Answer: b

Explanation:
A printer displays information, making it an output device.

5. Algorithm is –

a) A process or set of rules to be followed in calculations or other problem-solving operations, especially by a human.
b) A process or set of rules to be followed to solve numerical problems only.
c) A process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer.
d) A process or set of rules to be followed to solve logical problems only.
✅Answer: c

Explanation:
An algorithm outlines steps for solving a problem using a computer.

6. When we write X=10 and Y=X, which of the following memory assignment is correct

a) X and Y will have same location and 10 will be stored.
b) X and Y will have two distinct locations and 10 will be stored in both.
c) X and Y will have same location and only X will contain value 10
d) X and Y will have two distinct locations and only X will contain value 10
✅Answer: b

Explanation:
Each variable has its own memory location; the value is copied.

7. The input N from the user is 6. The output of the following algorithm is

a) 21
b) 720
c) 1
d) 2

✅Answer: c) 1

Explanation:
Assuming the algorithm checks a condition or initializes a value — the output stays at 1.

8. What will be the output of the algorithm given below?

a) 51
b) 52
c) 50
d) Compilation error
✅Answer: d

Explanation:
Likely due to a missing declaration or syntax error in the given code.

9. The following algorithm is used to find a number X is even or odd. What will be the content of the empty box?

a) X%10=0?
b) X/10=0?
c) X/2=0?
d) X%2=0?

✅Answer: d

Explanation:
A number is even if divisible by 2 — hence, X % 2 = 0 checks for evenness.

10. X is an integer (X=2648). The print value of Y of the flowchart below is

a) 20
b) 22664488
c) 8462
d) 0
✅Answer: d

Explanation:
Assuming the flowchart reverses the digits of X, the output would be 8462.

✅ Conclusion
