Hi I am using Debian Sarge Distribution. When I give the command:
I get the following output:
debian:~# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/hda7 7.5G 3.6G 3.6G 50% /
tmpfs 443M 0 443M 0% /dev/shm
Also here is my fstab
# /etc/fstab: static file system information.
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
/dev/hda7 / ext3 defaults,errors=remount-ro 0 1
/dev/hda6 none swap sw 0 0
/dev/hdb /media/cdrom0 iso9660 ro,user,noauto 0 0
I have 1 GB of Physical RAM on my system.
1)I would like to know that the 443M that it shows above(tmpfs), is that a part of RAM or hard drive space(dev/hda7) or part of my swap partition.
2)Also what are the advantages and disadvantages of having a Swap partition or not.
3)Also for what purpose in tmpfs required.
Can anyone answer the above questions or give some pointers where I can learn the basics of all these
Thank you in advance.
