Memory

Memory

1. ROM

   • Stores the instructions which are needed to ‘boot up’ the computer.
   • ROM is non-volatile, meaning that the content is stored even when the computer is switched off.
   • ROM means Read Only Memory

2. RAM (Random Access Memory)

   • Stores the instructions and data that are needed while programs are being used (e.g. programs such as PowerPoint, the operating system and data from open files)
   • RAM is volatile, meaning that the data is not stored when the computer system is switched off.

3. Virtual Memory

   • When we open more applications or files it starts to slow s down and then thats when Virtual Memory comes in
