What is the binary representation of the decimal number 13?

• 1100

• 1101

• • 1011

• 1110

In a floating-point binary number, what does the mantissa represent?

• The exponent part of the number.

• The precision of the number.

• The binary equivalent of the number.

• The actual number without the exponent.

The exponent in a floating-point number system is used to:

• Determine the sign of the number.

• Indicate the position of the decimal point.

• Represent the actual number.

• Specify the size of the data type.

What distinguishes bitmapped graphics from vector graphics?

• Bitmapped graphics are resolution independent.

• Bitmapped graphics are made up of pixels.

• Vector graphics cannot be resized without loss of quality.

• Vector graphics are composed of paths.

Which of the following is true about vector graphics?

• They consist of pixels.

• They lose quality when scaled.

• They are defined by mathematical equations

• They have a fixed resolution.

The component of the computer that performs arithmetic operations is known as the:

• Arithmetic Logic Unit (ALU).

• Central Processing Unit (CPU).

• Control Unit (CU).

• Graphics Processing Unit (GPU).

A data bus in a computer system is used to:

• Carry data between the processor and the memory.

• Specify the location of data in memory.

• Transfer control signals.

• Provide power to the processor.

The address bus is responsible for:

• Carrying the actual data.

• Determining the speed of the processor.

• Carrying the address of the memory location.

• Indicating the operation type (read or write).

In a computer system, the busses that connect the processor, memory, and other components are essential for:

• Storage only.

• • Output only.

• Communication between components.

• Internet connectivity.

What is the role of a compiler in computing?

• It executes programs line by line.

• It translates high-level programming code into machine code.

• It compresses files to save disk space.

• It performs calculations on binary data.
