Just fine. When my software or hardware has a problem, I know how to fix it. It is just a tool over which I have total control. No need for outside assistance.
But did they think that only white college educated Americans could work a PC?
Many people can operate an appliance...as long as it doesn't break down.
Can you explain the consequence of priority inversion in a real time operating system? How about a quick exposition on the merits of FSK, PSK or QAM? Would you choose CSMA/CD or token passing for best deterministic response? How did Shannon improve upon Nyquist's sampling theory?
If any of that wasn't familiar then we aren't having a discussion between peers.
A low-priority task holds a resource needed by a high-priority task, and so the high-priority task can't execute until all intermediate-priority tasks have been serviced.
How about a quick exposition on the merits of FSK, PSK or QAM?
The latter allow more data to be exchanged in a given bandwidth, but are more complex and more sensitive to frequency-dependent timing distortions.
Would you choose CSMA/CD or token passing for best deterministic response?
Token passing.
How did Shannon improve upon Nyquist's sampling theory?
Did he clarify the exact way in which frequencies above f/2 fold back, or had Nyquist already done that?
