Consider 500 GB hard drive with 5 KB block size. Calculate the size of the file allocation table if entry for each block needs 4 bytes.
Consider 500 GB hard drive with 5 KB block size. Calculate the size of the file allocation table if entry for each block needs 4 bytes. [5]
Parameter Value ------------------ Hard drive size 500 GB Block size 5 KB FAT entry size 4 bytes per block --- $$500 \text{ GB} = 500 \times 1024 \times 1024 \text{ KB} = 524{,}288{,}000 \text{ KB}$$ Each block requires exactly one FAT entry, so first find how many blocks exist. $$\text{Total Blo...
