A. modem or d. voice input. Not a port because a port allows one to insert a peripheral device but not really communicate. I have no idea what an expansion slot is. It could be d. voice input because this allows a person to hold an audible conversation.
But I'd go for modem because a modem lets you connect devices like laptops, tablets, phones, computers etc. and share data between them. So things like mailing are possible (I THINK)! <span />
Answer: In operating system a code segment which accesses some shared variables or resources one at a time atomically such other no other code or process is accessing that resource or variable at the same time.
Entry section code block allows the access to the shared resource or variable and exit section code signals the termination from access to the shared resource or variable.
Explanation:
Entry and exit section codes needs to check certain properties before allowing the access and removal of access to a particular code segment.
These conditions are:
1. Bounded waiting.
2. Mutual exclusion.
3. checking thread execution status to allows other threads to enter the critical section (CS).
Answer:
Cost saving is the fundamental goal of outsourcing.
Explanation:
Initially the companies where outsourcing task only for Cost cutting. But nowadays, the companies do that for so many other reasons like, increase the efficiency, reducing overhead, to concentrate on core business peacefully, to obtain more profit, etc.
The cultural diversity does not affect or make companies to outsource.
We can indirectly increase the quality but it is not the primary goal of outsourcing.
Brand expansion will holds good, only the BPO is run under the name of the company. But this is once again not the major objective.
