Computer RAM (random access memory) holds the data for the CPU, typically loaded from hard disks or read from keyboard.

Find out your memory configuration

To find out how much RAM you have, enter

# hwinfo --memory
01: None 00.0: 10102 Main Memory
  [Created at memory.59]
  Unique ID: rdCR.CxwsZFjVASF
  Hardware Class: memory

  Memory Range: 0x00000000-0xc7fffffff (rw)
  Memory Size: 50 GB

In this case you have 50 GB of memory.

# dmidecode | less
