Memory

Memory

1. RAM

   • Ram stands for random access memory
   • Ram is a very fast but volatile type of memory .
   • Computer use RAM to store applications and data
   • If power is turned off all of RAM is lost this is called volatile memory and the switches (RAM) are jumbled once again
   • RAM contains the instructions for your programs like word and Spotify and are used when you open those up when you click off of those servers then those instructions are no longer needed which is why that data is not retained.

2. ROM

   • Read only memory
   • All data is retained in ROM when the computer is turned off this is called non volatile
   • ROM stores the instructions which allows the computer to start up
   • It is a flash memory clip within the computer

3. Cache

   • Cache is a hardware or software component that stores data
   • It only temporarily stores data
   • Stores frequently used instructions so that they can be executed faster when needed again

4. virtual memory

   • It is a memory management technique
   • It is a section of volatile memory and is created when the computer is running
   • The operating system makes part of the storage drive available to use as RAM
   • It is connected to the hard disk (secondary storage) and when RAM is full it can swap that instruction into virtual memory creating space for the command needed at that point
