BINARY

100

What is Binary in computer?

its like the language use by the computer that has only 2 characters: 0 and 1.

200

Convert 65 to Binary.

01000001

300

Convert 10001 to Decimal (ASCII code).

17

400

Complete this binary operation:

1000 + 1001

10001

500

Complete this Binary Operation:

101 + 11 - 1

101 + 11 = 1000

1000 - 1 = 111

Answer is 111

Logic gates

100

Name All the 3 basic Logic gates.

AND

OR

NOT

200

Write the expression for the NOT logic gate with input A.

A'

300

Fill in the Truth table for this Logic gate expression: A' + B

(Draw your own truth table, then show to the teacher)

400

Draw the Logic gate for this expression:

(A' + B') + (C'.D)

(Draw your own Logic gate and show to the teacher)

Programming Terms

100

Algorithms

100

List the 4 Problem Solving Process:

Identify target output

Decompose in Plain English

Write Pseudo-Code

Draw flowchart.

200

Write a pseudo-code for this problem:

Volume = 4/3 Pi r³

Comment: Calculate Volume of Sphere

Start

Pi = 3.14

Input radius

Calculate Volume = 4/3 * Pi * radius * radius * radius

Output Volume

End.

300

Draw the flowchart for this problem:

Volume = 4/3 Pi r³

(Draw your own flowchart and show to teacher)

400

Decompose this problem in plain English.

Volume = 4/3 Pi r³

Set value for Pi to 3.14

Input radius

Calculate the Volume by divide 4 with 3 then multiply with Pi and multiply with the radius 3 times.

Output the Volume.

Python Codes

100

Name the programming language we use in this class.

PYTHON

200

What the is command use in Python for output.

print

300

Debug this Python Code:

village = input("Where are you from?")

village = str(input("Where are you from?"))

400

Write the Python code for this line from a Pseudo-Code.

Output Name

print ("Hello {0}" .format(Name))

500

Write the Python code for this problem:

Solve  Y = M / 2 + 2n

M = int(input("Enter value for M"))

n = int(input("Enter value for n"))

Y = M / 2 + 2*n

print(" Y = {0}" .format (Y))
