Using ramfs or tmpfs you can allocate part of the physical memory to be used as a partition. You can mount this partition and start writing and reading files like a hard disk partition. Since you’ll be reading and writing to the RAM, it will be faster.
When a vital process becomes drastically slow because of disk writes, you can choose either ramfs or tmpfs file systems for writing files to the RAM.
Both tmpfs and ramfs mount will give you the power of fast reading and writing files from and to the primary memory. When you test this on a small file, you may not see a huge difference. You’ll notice the difference only when you write large amount of data to a file with some other processing overhead such as network.
Mounting tmfs:
# mkdir -p /mnt/tmp
# mount -t tmpfs -o size=20m tmpfs /mnt/tmp
The last line in the following df -k shows the above mounted /mnt/tmp tmpfs file system.
Ans:2 IDE hard disks (well, devices, actually) are hd<drive><partition>. SCSI devices (and kernel-level emulation of SCSI devices, like USB devices or, in some cases, CD-RW drives) are sd<drive><partition>.
The standard partitioning scheme nowadays is (assuming your drive is hda):
Code:
hda1 => bootloader and kernel(s)
hda2 => swap space
hda3 => root filesyste
