Question

Suppose a picture is represented on a display screen by a rectangular array containing 1024 columns and 768 rows of pixels.

If for each pixel, 8 bits are required to encode the color and another 8 bits to encode the intensity,

how many byte-size memory cells are required to hold the entire picture?

Since he number of pixels is 1024x768=786432. Each pixel requires 8 bit; therefore, each pixel requires 1 byte. The size of the memory must be 786432 bytes. This is 786432/1024=768 KB.

Is my answer correct?

Explanation / Answer

Yes you are solving correctly-

The number of pixels is 1024x768=786432. Each pixel requires

8 bit; therefore, each pixel requires 1 byte. The size of the memory must be

786432 bytes. This is 786432/1024=768 KB. Answer=768 KB
