Multiple choice

Directions: Read the following information carefully and answer the question given below.

Employing nano-level technologies to “re-storage” existing computers ultimately promises a vast increase in memory storage capability and would affect the full range of data input. The strategy of employing these technologies can increase RAM memory capabilities by 80 percent and hard disk memory by at least 60 percent. The storage of a greater amount of memory would in turn allow computers to perform a greater number of functions.

Which one of the following conclusions can be properly drawn from the passage above?

  1. RAM memory is the most efficiency means of storing memory.

  2. Insufficient storage capacity is the result of RAM memory interfering with the hard disk memory.

  3. Twenty percent of current RAM memory is not considered sufficient.

  4. <div align="justify">The employment of new computer technologies could allow computers to perform a greater number of functions.
