Answer:
A. Hertz ----f amplitude.
Explanation:
The rules of physics confirm that frequency is measured in HERTZ and the amplitude is measured in Decibel. And hence, the correct option here is certainly the first option as it states that the frequency is measured in HERTZ and the amplitude is measured in Decibel. Hence, the first one is the correct choice for this question.
Answer: C) spin-lock with test and set
Explanation:
In spinlock, when a thread locks a spinlock then it continuously retrying locking until it succeeds. Spinlock is the lock that cause thread and continuously check that whether the lock are available or not for synchronization.
So that is why spinlock is best synchronization solution as it is not allowing any another thread.
On the other hand, in mutex thread try to lock a mutex and then, it automatically go to sleep mode before locking and immediate allow another thread to run.
Answer:
The default for automatic replies in outlook is turned off, so the user has to turn it on in order to use it.
Out.look is a program developed by Micro.soft for managing e-mails, being together with G.mail one of the most used worldwide. As in most of these programs, you can configure automatic responses in order to give a quick and generic response to certain types of messages (or even all). Now, this option is disabled by default, so the user must activate it through the configuration of the email box.
I believe the answer is B. Optimization because it means to make work more efficient but I might be wrong. Checking definitions, this one seems more logical.
Answer and Explanation:
Omnidirectional antenna are those antennas which receives the signals from multiple directions equally.These are the antennas that cannot get the signal from a particular direction thus gives the low throughput.
To get high throughput, directional antennas should be installed because they receive the signal from a particular direction only .Thus the signal received from these antenna work for a certain area.Example-Television antenna at homes are directional antennas names as Yagi-uda antennas.
