How does a history of colonization in sub-saharan africa influence sustainable economic development in the region today?.

The four conditions (mutual exclusion, hold and wait, no preemption and circular wait) are necessary for a resource deadlock to

Evgen [1.6K]

Explanation:

The conditions sufficient for a resource deadlock to occur is when a deadlock will prevail for process A, B, and C when two resources R and S; if only one instance of each resources is allowed.

Solution

Deadlock conditions

A deadlock is a situation where two or more processes request for same critical resource at the same time.

The mutual exclusion applies a restriction to a resource when the resource is used by any process, it should become unavailable for the other resources

The hold and wait allocations explains that any process which is allocate resources must hold them; till all needed resources are nor sure.

In the meantime, if any other processes need a resource which is held by another process, then the latter will release the resource to prevent deadlock.

No pre-emption states that the operating system can grant access to resources to another process while it is in use by another process; depending on the priority , to prevent deadlock.

Circular wait should not be implemented so that resources being requested by process are allocated when they get free.

Now,

Three processes A, B, and C functions on a system, having two distinct resources R and S.

The resource R has one instant active while resource S has two instances available.

The instance of R is allocated to a process A after request. first instance of resource S is allocated to process B, and second instance of resource S is allocated to process C.

When a request is placed by process B for resource R, then the resource is not available for execution. the process A request for resource S which is used by both C and B.

All the four conditions prevail in this situation; yet deadlock does not occur.

The resource S is released by process C and is allocated to process A. when process A finishes, it releases resources and resources R is allocate d to process B.

Hence all three processes end without a deadlock.

However, the deadlock will prevail for process A, B, and C when two resources R and S; if only one instance of each resources is allowed.

Suppose an American worker can make 20 pairs of shoes or grow 100 apples per day. On the other hand, a Canadian worker can produ

Elan Coil [88]

Answer: Higher; Comparative advantage

Explanation:

A country or a firm has a comparative advantage in producing a commodity if the opportunity cost of producing that commodity in terms of other commodities is lower than the other country or firm.

Opportunity cost is the benefit that is foregone for an individual by choosing one alternative over other alternatives available to him.

If the opportunity cost is lower for an individual then this will benefit him whereas if the opportunity cost is higher then this will not benefit the individuals.

Therefore,

United states's Opportunity cost of producing a pair of shoes = $\frac{100}{20}$

= 5 apples have to be foregone for producing a pair of shoes

Canada's Opportunity cost of producing a pair of shoes = $\frac{20}{10}$

= 2 apples have to be foregone for producing a pair of shoes

Hence, Canada has a comparative advantage in producing pairs of shoes because Canada's opportunity cost of producing a pair of shoes is lower than United states opportunity cost.
