誰かがこの問題を解決する方法を説明できますか？
1. **What is the maximum size of a file that could be handled by single indirect and double indirect?**
Block size is 2K
Address size is 4 Bytes
12 slots for direct disk blocks
One slot each for single indirect and double indirect.

2. **What is the maximum size of a file that could be handled by single indirect and double indirect?**
Block size is 4096 bytes can contain 1024 block references.
12 slots for direct disk blocks
One slot each for single indirect and double indirect.
私の試み：
1.
Block size is 2K = 2**11
Address size is 4 Bytes = 2**2
in one block are (2**11/2**2)= 2**9 pointers
12 slots for direct disk blocks
One slot each for single indirect = 2**9
and double indirect. = 2**18
Maximum file size
( 12 + 2**9 + 2**18 ) * 2**11 = 2**29 ~ 536 MB

2.
Block size is 4096 bytes can contain 1024 block references
12 slots for direct disk blocks
One slot each for single indirect = 1024 = 2**10
and double indirect. = 1024**2 = 2**20
Maximum file size
( 12 + 2**10 + 2**20 ) * 2**12 = 2**32
( 12 + 1024 + 1024**2 ) * 4096 = ~ 4GB
これが正しいのか、私がどこで間違っているのかはまだわかりません。
