The FAT method incorporates free-block accounting into the allocation data structure.
The File Allocation Table (FAT) method is a file system designed to store file information in a designated entry format. The operating system makes use of it to manage files on hard drives and other computer devices.
It usually comprises an entry for each block. As such, it is indexed via the block number. This helps to locate files faster based on the address of the given number of the free blocks as opposed to using the traditional grouping method.

D.) So that they can lower the I2R losses
The programing language, R has a unite unite function in the tidyr package. Hence, the code chunk which let's the analyst create the location column is; <em>unite (stores, "location”, city, state, sep=",") </em>
- The syntax for the unite function is ; unite(data,col,..., sep)
- <em>data</em><em> </em><em>=</em><em> </em><em>dataframe</em><em> </em><em>from</em><em> </em><em>which</em><em> </em><em>data</em><em> </em><em>is</em><em> </em><em>to</em><em> </em><em>be</em><em> </em><em>extracted</em><em> </em><em>`</em><em>;</em><em> </em>stores
- <em>col</em><em> </em><em>=</em><em> </em><em>name</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>new</em><em> </em><em>column</em><em> </em><em>;</em><em>"</em><em> </em>location"
- <em>.</em><em>.</em><em>.</em><em> </em><em>=</em><em> </em><em>dataframes</em><em> </em><em>to</em><em> </em><em>be</em><em> </em><em>merged</em><em> </em><em>;</em><em> </em>city, state
- <em>sep</em><em> </em><em>=</em><em> </em><em>seperator</em><em> </em><em>;</em><em> </em>","
Hence, the required syntax goes thus :
- unite (stores, "location”, city, state, sep=",")
