Which of the given options best describes the truthfulness of the following statements? (i) In 1-bit images, each pixel is stored as a single byte. (ii) A 1-bit image with a resolution of 640 × 480 needs a storage space of 640+480 bits.

Which of the given options best describes the truthfulness of the following statements? (i) In 1-bit images, each pixel is stored as a single byte. (ii) A 1-bit image with a resolution of 640 × 480 needs a storage space of 640+480 bits. Correct Answer (i) False, (ii) False

Key Points

 Option 1: ​In 1-bit images, each pixel is stored as a single byte.

False, 1-Bit, or 1bit  means that each pixel is stored as a single bit. i.e. 0 or 1. The names black-and-white, B&W, monochrome or monochromatic are often used for this concept, but may also designate any images that have only one sample per pixel, such as grayscale images.

Option 2: A 1-bit image with a resolution of 640 × 480 needs a storage space of 640+480 bits.

False, 1-bit image is also known as 1-bit monochrome image because it contains one color that is black for off state and white for on state.

A 1-bit image with resolution 640 × 480 needs a storage space of 640 × 480 bits. 640 × 480 bits.

= (640 × 480) / 8 bytes

= (640 × 480) / (8 × 1024) KB

= 37.5KB.

Hence the correct answer is (i) False, (ii) False.

Suppose you are compiling on a machine with 1-byte chars, 2-byte shorts, 4-byte ints, and 8-byte doubles, and with alignment rules that require the address of every primitive data element to be an integer multiple of the element's size. Suppose further that the compiler is not permitted to reorder fields: padding is used to ensure alignment. How much space will be consumed by the following array? struct { short s; char c; short t; char d; double r; int i; } A[10]; /*10-element array of structs*/
