Unix-like operating system use two internal tables to keep track of open files – the per-process file descriptor table and the system-wide file table. suppose on a unix-like operating system, process a has two files open and process b has three files open. two files are shared between the two processes. how many entries are in the per-process table of process a, the per-process table of process b, and the system-wide tables respectively?

1. 2 entries in per-process table for process a 
2. 3 entries in per-process table for process b 
3. 3 entries in system-wide table 
 Since process a has 2 files open, it uses 2 file descriptor entries.
 Since process b has 3 files open, it uses 3 file descriptor entries.
 Since there are only 3 unique files open (2 for process a + 3 for process b - 2
shared in common), the system-wide table only uses 3 file entries.

Via:   "if you are found to be supplying or dealing drugs, the punishment is likely to be tough. supplying drugs doesn’t just apply to dealers. if police suspect that you intend to share drugs with your friends, this is still considered to be supplying.

being suspected of supplying drugs means you are much more likely to be charged. the amount of drugs found on you, and whether you have a criminal record, will be taken into account when a punishment is being decided.

decisions to prosecute are taken by the public prosecution service. the maximum sentences for intent to supply drugs are:

- up to life in prison or an unlimited fine (or both) for a class a drug- up to 14 years in prison or an unlimited fine (or both) for a class b or class c drug."sorry if this was a school question, you didnt supply options so i assumed it was a personal question, which if it is, reconsider selling or having possesion of any drugs at all. i wish you the best!
