Dear arash :)

Historically, a partition size is static. This requires a system installer to 
have to consider not the question of "how much data will I store on this 
partition", but rather "how much data will I *EVER* store on this partition". 
When a user runs out of space on a partition, they either have to 
re-partition (which may involve an entire operating system reload) or use 
kludges such as symbolic links. 

The notion that a partition was a sequential series of blocks on a physical 
disc has since evolved. Most Unix-like systems now have the ability to break 
up physical discs into some number of units. Storage units from multiple 
drives can be pooled into a "logical volume", where they can be allocated to 
partitions. Additionally, units can be added or removed from partitions as 
space requirements change. 
This is the basis of a Logical Volume Manager (LVM).
