When computers were first invented, their memory was measured in sheets of paper that could be coded. The new Playstation 5 has a storage of 825 Gb. How many sheets of paper would it take to fill the new Playstation 5?

The number of cards required to fill an 825 GB PlayStation is 6.875 × 10⁹ sheets of paper or 6875000000 sheets of paper

Explanation:

The coded sheets of paper are known as punched cards. Punched cards are paper cards where holes may be punched by hand or machine to represent computer data and instructions. Each hole in a card represents one bit: It either can be punched, or not punched. The holes in a classic card are arranged in 80 columns and 12 rows. The maximum information that can be stored in the punched card = 80 x 12 = 960 bits.

8 bits = 1 byte

960 bits = 120 bytes

1 gigabyte = 10⁹ bytes

Therefore, the number of cards required to fill an 825 GB PlayStation is;

(825/120) × 10⁹ = 6.875 × 10⁹ sheets of paper or 6875000000 sheets of paper
