Microprocessors and Memory

• Although these microprocessors tend to be
  slower than their PC counterparts, they are
  adequate for the tasks that PDAs perform. The
  benefits of small size and price outweigh the
  cost of slow speeds

Operating Systems

• The operating system contains the
  pre-programmed instructions that tell the
  microprocessor what to do.
• The operating systems used by PDAs are not as
  complex as those used by PCs. They have fewer
  instructions, which require less memory.
