Consider user accounts on a computer system with a Web server configured to provide user Web areas. In general, this uses a standard directory name, such as “public_html,” in a user’s home directory. However, access control needs to be properly set to allow users (with or without user accounts on the system) to browse the webpages. Assuming there are one main page (index.html), two pictures files (a.jpg and b.jpg) stored in an sub-directory (Image) and one pdf file (c.pdf) stored in an sub-directory (Doc), all under the public_html. (a) Specify the access matrix for each directory (excluding home directory) and files that allows everyone to view the webpage. (b) Draw a directed graph that represented to the access matrix
