hardware and software

1. BIOS and CPU's

   • bios is what is in the rom memory. the bios contain the bootstrap. this is what contains the steps in which the operating software is loaded
   • the cpu is what executes all of the programs

2. storage devices

   • rom is one type of memory. you cannot rom as it is essential therefore it is saved when it is turned off. an example is that it stores the instructions for the computer to start up when it is turned on
   • another type of storage is ram. it is a fast and temporary type of memory where apps and programs are stored. for example the operating software is stored there.
