Why on Unix/Linux OS machines are showing less memory (RAM) than it is? Let say i have Ubuntu machine whose have 1024 MB ram, when i open "System Monitor" "Resources" tab it shows 1001.2 MB. How i can get all RAM from Unix/Linux machines?

link doesn't help -Why does Red Hat Linux report less free memory on the system than is actually available?

You have provided a very vague sentence but i'll do my best. You likely have an integrated graphics card. A portion of the ram will be taken for video memory. You should be able to control how much is taken in bios.
