Question 1: What does the term “pixel” stand for?
A) Picture Element
B) Picture Pixel
C) Pixel Element
D) Image Pixel
Explanation: Pixel is short for Picture Element, which is a collection of dots forming an image.
Question 2: How are pixels represented in black and white images?
A) Each pixel is represented as one bit
B) Each pixel is represented as one byte
C) Each pixel is represented as one nibble
D) Each pixel is represented as one word
Explanation: In black and white images, each pixel is represented as one bit, where 0 stands for black and 1 stands for white.
Question 3: How many bits are used to store shades of grayness in images?
A) 1 bit
B) 4 bits
C) 8 bits
D) 16 bits
Explanation: 8 bits are used to store shades of grayness in images, allowing for 256 different shades.
Question 4: Which encoding method is used for colorful images?
A) RGB encoding
B) CMYK encoding
C) YUV encoding
D) HSL encoding
Explanation: RGB encoding uses one byte for Red, one byte for Green, and one byte for Blue to represent one pixel in colorful images.
Question 5: What does RGB encoding stand for?
A) Red, Green, Blue
B) Red, Gray, Black
C) Red, Green, Brightness
D) Red, Green, Black
Explanation: RGB encoding uses three bytes to represent one pixel, with each byte representing the intensity of red, green, and blue.
Question 6: What does TrueType refer to?
A) Scalable fonts by Microsoft and Apple
B) Bitmap fonts by Microsoft and Apple
C) PostScript fonts by Microsoft and Apple
D) Vector fonts by Microsoft and Apple
Explanation: TrueType is a scalable font technology developed by Microsoft and Apple.
Question 7: What is the purpose of brightness and chrominance components in images?
A) To determine the size of the image
B) To represent colors accurately
C) To enhance image contrast
D) To separate image details from color information
Explanation: Brightness and chrominance components separate image details from color information, allowing for more efficient compression.
Question 8: What is the difference between luminance and chrominance?
A) Luminance represents brightness, while chrominance represents color information
B) Luminance represents color information, while chrominance represents brightness
C) Luminance and chrominance are the same
D) Luminance represents brightness, while chrominance represents image size
Explanation: Luminance represents the brightness component of a pixel, while chrominance represents the color components (such as blue and red).
Question 9: Which geometric structures are used for image scaling?
A) Lines and curves
B) Rectangles and circles
C) Triangles and squares
D) Polygons and ellipses
Explanation: Geometric structures for image scaling are collections of lines and curves, often represented using analytical geometry.
Question 10: Which technology is used for scalable fonts in Computer Aided Design (CAD)?
A) TrueType
B) PostScript
C) OpenType
D) Type 1
Explanation: PostScript is a scalable font technology popular in Computer Aided Design (CAD) applications.
