Do research on the Web to learn more about Apple’s decision to withdraw from the EPEAT program and why it later reversed that decision. Write a one-page report summarizing your findings.

Program Plan Intro

Components of computer:

Computer has four major components, they are:

  • Central processing unit (CPU)
  • Memory unit
  • Input devices
  • Output devices

Central Processing Unit (CPU):

  • CPU plays the key role in a computer by carrying out instructions of a computer program.
  • It performs all the basic logic, arithmetic, controlling and input/output operations that are specified by the instructions.
  • The CPU comprises of two units, Arithmetic logic unit (ALU) and control unit (CU).

Memory unit:

  • Once computer program instructions set are transformed into machine code by CPU, the machine code is stored in memory.
  • Then the CPU fetches the required data and instructions from memory and performs the required operations and then sends the result and next instructions set back to memory.

Input devices:

  • The devices used by the user to feed information to the computer, such as a hard drive, keyboard, or a networking card.
  • These devices get the data from outside world into the computer in the way that human eyes and ears bring the data to brain.

Output devices:

  • Output devices are used by computer to deliver information to user, such as a monitor, printer, and speaker.
  • The CPU takes the machine code present in memory and converts it into a format that is mandatory by monitor’s hardware.
  • Then the monitor’s hardware converts that information into different light intensities so that you see words or pictures.

Explanation of Solution

Apple’s decision to withdraw from EPEAT program:

  • The Apple felt that EPEAT is too narrow in its scope.
  • It does not track removal of toxic materials or energy efficiency.
  • It doesn’t certify smartphones or tablets that are Apple’s largest revenue streams.
  • A new environmental policy was been unveiled by then CEO to customers as well as shareholders...
