HI guys!

An 8-bit color image may contain the exact information of a
black & white image ?

Each pixel of a grey scale image can be represented using 1 bit ?

Progressive videos requires higher bandwidth to transmit image than the
interlace videos?

MPEG-1 Layer 3 encoding is used to compress the video?

Thanks guys!
please answer yes or no, cheers
