### Questions 1-40
**Question 1**
Which of the following is the correct binary representation of the decimal number
13?
A) 1101
B) 1011
C) 1110
D) 1001
**Answer: A**
,2|Page
**Rationale:** Binary uses base-2 with values of 2^n (128, 64, 32, 16, 8, 4, 2, 1).
For 13: 8+4+1 = 13, which is binary 1101. Place values: 1×8 + 1×4 + 0×2 + 1×1 =
13.

**Question 2**
Which notation system uses numbers 0-9 and letters A-F?
A) Binary
B) Octal
C) Hexadecimal
D) Decimal
**Answer: C**
**Rationale:** Hexadecimal (base-16) uses digits 0-9 and letters A through F to
represent values 10 through 15. It is commonly used in computing to represent
memory addresses and color codes.

**Question 3**
What is the decimal value of the hexadecimal number 16AE?
,3|Page
A) 5806
B) 16AE (cannot be converted)
C) 5806
D) 100111
**Answer: A**
**Rationale:** Hexadecimal notation uses the prefix 0x or suffix h. 16AEh =
(1×16³)+(6×16²)+(10×16¹)+(14×16⁰) = 4096 + 1536 + 160 + 14 = 5806.

**Question 4**
A value that can only be TRUE or FALSE is what type of data?
A) Integer
B) String
C) Boolean
D) Float
**Answer: C**
**Rationale:** Boolean data types have only two possible values: true or false
(sometimes represented as 1 or 0). This is used in programming logic, conditional
statements, and database queries.

**Question 5**
What is the term for a data type that represents a whole number without a decimal
point?
A) Float
B) Integer
C) Character
D) String
**Answer: B**
**Rationale:** Integers are whole numbers (positive, negative, or zero) without
fractional components. Examples include: -5, 0, 42. In contrast, floats (floating-
point numbers) contain decimal points.

**Question 6**
The data displayed on your monitor is BEST described as:
A) Input
B) Processing
C) Output
D) Storage
