Answer:
D.
Explanation:
In combinational circuits, the current output values are always the same for the same set of input values, regardless the previous values.
We say that combinational circuits have no memory, or that the circuit has no feedback from the outputs.
For sequential circuits, on the contrary, the current output values are not based in the current input values only, but on the previous output values as well.
So, the fact of having a defined set of input values at a given moment, doesn't guarantee which the output values will be.
We say that sequential circuits have memory, or that they have feedback from the outputs.
Examples of these type of circuits are R-S, J-K, D or T flip-flops.
Answer:
A Port Replicators.
Explanation:
Port replicators are devices or extension. They are plugged into the laptop's usb port to provide extra ports to connect other external devices needed by the laptop.
Docking stations does the same thing, but the laptop is plugged into the docking station holding the needed devices, and meant for that laptop brand.
Answer:
A switch connects multiple devices to a network. ... devices are usually integrated into a multipurpose network device
I personally feel that e-mail can be used for more business settings and as a more formal approach to things as opposed to a text, but option C seems to be more of an opinion. I would go with C or D.
