File system , Direct, single indirect ..

Question

Consider a unix file system which uses 12 Direct and a single indirect block pointer for file implementation. Assume that the block size is 4KB and each block can hold 512 block addresses. The maximum size of a file on such a system is ___________ KB.

Answer 1

answer is 2.046 Mb ...as 12 direct gives 48Kb and 1 indirect gives 2048Kb

Answer 2

Block size = 4KB

Each block can hold = 512 block addresses

According to given ques.

Maximum file size = (disk block addresses ) ^ single indirect * Block size

= (2^9)^1 * 4KB = 2048KB = 2MB
