Green computing is the use of computers and related resources which is environmentally responsible. Energy-efficiency and e-waste are two major techniques involved in green computing. Energy efficiency involves implementation of energy-efficient central processing units (CPUs), servers and peripherals as well as reduced resource consumption. And e-waste is the proper disposal of electronic waste.

Answer:
C. Yes, public key encryption is built upon computationally hard problems that even powerful computers cannot easily solve
Explanation:
Public Key encryption makes use of a public key and a private key to secure data sent over the internet, such as credit card information. The public key is shared publicly, as seen with an SSL/TLS certificate. The data encrypted by the public key can only be decrypted by the private key found on the website server. Data encrypted by the private key can only be decrypted by a specific public key. This makes public key encryption complex and hard to solve, making it very secure .
