Answer 1

$\huge{\underline{\sf{Answer:-}}}}$

Multiuser operating systems often provide a mechanism for enforcing disk quotas. A system administrator assigns each user a maximum allotment of files and blocks and the operating system makes sure that the users do not exceed their quotas.

Answer 2

Answer:

Disk-Space Management

Since all the files are normally stored on disk one of the main concerns of file system is management of disk space.

Block Size

The main question that arises while storing files in a fixed-size blocks is the size of the block. If the block is too large space gets wasted and if the block is too small time gets waste. So, to choose a correct block size some information about the file-size distribution is required. Performance and space-utilization are always in conflict.
