In the ASCII Art shown below, every character is represented by a sequence of 8 bits. How many bytes are required for one individual  character in the image?

In this ASCII image, there are 3 lines, with 20 characters in each line.This includes spaces and the special characters that move to the next line. How many characters are in the image in total?

How many bits are required for representing the entire image?                                                                                       Hint: each character is a byte and there are sixty characters in the ASCII image.

How many bytes are required for representing the entire image?

You really enjoy taking pictures with your mobile phone. You purchase a 16GB memory card and you want to know how many pictures you can store on the memory card. The size of each individual picture is approximately 4MB.                                                                    How many pictures can be stored on your memory card?
