How to Use and mount RAMFS / TMPFS in Centos, RHEL, Fedora, Ubuntu?

RAMFS / TMPFS is used to assign or allocate a part of physical memory to be used as a individual partition which can be used for storing data (Reading, Writing) like all other Disk partition on a system. As the data is stored in RAM (Random Access Memory) it is much faster than that of writing or reading from a System Physical disk Partition.
Performance can be measured when writing or Reading a large file from this partition (Small File size wont give you the performance). Mounting RAMFS and TMPFS is same on almost all linux distribution RHEL, Centos, Ubuntu, Fedora.
