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: True.
Explanation:
When a user wants to make a phone call, he needs to inform to the called party, that he wants to call him.
The only way to do this, is setting up a connection between the two phones, which is started by the calling party informing to the phone switch which is directly connected to, that he wants to make a call, picking up the phone, which modifies his connection state, making him available for calling.
The switch then signals him (sending him an audible call tone) so he can send the digits that identify the called party.
When the destination switch identifies the called user, signals him also (sending in this case a ringing tone).
When he picks up his phone, answering the call, the connection is set up, and both people can talk each other.
Without all this signaling process, it would be completely impossible to set up the call.
