Consider a system consisting of m resources of the same type, being shared by n processes. Resources can be requested and releas
ed by processes only one at a time. Show that the system is deadlock free if the following two conditions hold: A. The maximum need of each process is between 1 and m resources
B. The sum of all maximum needs is less than m+n.
Let's say that our system is not deadlock free right now. If the system is in deadlock then sum of all allocations should be equal to the total number of resources i.e. B = m
Now the statement (b) says that sum of all maximum needs is less than m+ n i.e. A + B = C < m + n.
As from above deduction B = m so, A + m < m + n
or A < n, which means that there is one process for which need it zero as number of processes it greater than need and a process can request and release only one resource at a time. So, there are n-1 processes sharing m resources currently. But no process will wait permanently, hence there is a contradiction and there is no deadlock.
Berth's job became redundant because she lacks the computing skills. Perhaps, she has been using manual or analog type writing machine to do her job and was doing it well but with the advent of computer that replaces analog type writer, she will become redundant.
Explanation:
She needs to learn how to use the computer to type and do her job efficiently in the print industry.
The time when an LCD monitor is experiencing distorted
geometry is when there is a presence of the screen into having a display that
is not set on the resolution that is supposed to be in native, this is
indicative that it is experiencing distorted geometry.
