Question

for a screen resolution of 1920*1080 and an RGB color model.what is the approximate size of the frame buffer

Answer 1

The approximate size of the RGB color model's frame buffer is 6.2208 MB.

Explanation :

• In general, for each channel in a segregated frame needs 8 bits per pixel.

• As we know that every pixel contains 3 channels, In RGB model (red, green, blue), it takes 8x3 i.e., 24 bits to store a pixel of an image.

• If you download any image, you can find the no.of bits the frame takes to store a pixel of it, under the name BPP (Bits Per Pixel).

Calculating the approximate size buffer :

$Size Of The Frame Buffer (In Bytes) =\frac{ScreenResolution * BPP}{8 (As, 1 Byte = 8 Bits)}$

Size of the frame buffer (In bytes) = (1920 x 1080 x 24) / 8

                                                           = 49766400 / 8

                                                           = 6220800  Bytes

Converting 6220800  bytes into Mega Bytes :

1 Mega Byte = 10⁶ Bytes

6220800  Bytes = (6220800  / 10⁶ ) Mega Bytes

                            = 6.2208 MB

Therefore, The approximate size of the RGB model's frame buffer of the frame, whose screen resolution is 1920 x 1080, is 6.2208 Mega Bytes.
