Computer memories

1. some of the storage memories are

   • Read Only Memory (ROM)
     • It is built into the motherboard and is used by the PC to start the BIOS
   • Random Access Memory (RAM)
     • Save all kinds of information, from temporary processes to instructions for applications to run
   • Cache Memory (SRAM)
     • It saves the locations on the disk that the programs that have been executed occupy, so that when they are started again, access to the application will be faster.
       • There are three types of Cache Memories
         • L1 Cache
           • works at the same speed and instructions and data are saved
         • L3 Cache
           • they only come built into some of the more advanced microprocessors
         • L2 Cache
           • It is slower than L1 because they are processed in two ways, internal and external.
   • swap memory
     • they are used exclusively for operating systems like windows and linux
