Chapter 6, Problem 20SG

Program Plan Intro

Random Access Memory (RAM):

• It is a part of computer’s main memory, which is directly accessible by CPU.
• It is also known as main memory.
  • It contains memory chips which are used to read from and written to processor and other devices.
• The contents of RAM may alter when the processor selects and performs a program though the given program is in RAM.
• It is volatile type of memory.
  • Because, once the power is separated from the computer, user loses their content.
  • Therefore, user needs to save data, instructions and other information for future needs.

Explanation of Solution

Types of RAM:

There are two types of RAM such as Dynamic RAM (DRAM) and Static RAM (SRAM).

• DRAM:
  • DRAM chips contain higher access time.
  • DRAM chips are cheap.
  • Size of DRAM chips is large.
  • Speed of DRAM chips is slow.
  • DRAM provides reduced power usage because the data is stored in the capacitor...
