A Windows 2000 Server computer named server2 runs numerous 32bit applications and two 16bit applications. Users start the 16bit applications by running APP1.EXE for one application and APP2.EXE for another application. The 16bit applications are configured to run in the separate memory space. You want to create a performance base like chart in the system monitor for all the applications on server2. You add all of 32bit applications and now you want to add two 16bit applications. What should you do?

In the question, a statement is given, followed by two arguments, I and II. You have to consider the statement to be true even if it seems to be at variance from commonly known facts. You have to decide which of the given arguments, if any, is a strong argument. Statement: Should the US built a nationalised 5G network on its own? Arguments: Yes. There are serious concerns relating to the Chinese government’s influence into telecommunication network equipment markets and concerns relating to Chinese spying in the US knowing that the Chinese companies are really developed in the telecommunication network equipment markets. No. The proposal for the federal government to build a standalone network would be ‘expensive and duplicative’.

Workstations connected to a port on a modern lOBase-T Ethernet HUB all use the same bandwidth, i.e. the bandwidth is shared across all available ports, the less ports, the less bandwidth available per port
Bandwidth of balanced amplifier can be an octave or more, but is limited by the bandwidth of the coupler.
The capacity of a band-limited additive white Gaussian noise (AWGN) channel is given by $$C = W\,{\log _2}\left( {1 + \frac{P}{{{\sigma ^2}W}}} \right)$$     bits per second (bps), where W is the channel bandwidth, P is the average power received and σ2 is the one-sided power spectral density of the AWGN. For a fixed $$\frac{P}{{{\sigma ^2}}} = 1000,$$   the channel capacity (in kbps) with infinite bandwidth (W → ∞) is approximately
