Answer
Abstraction enables GPS system to facilitate the utilization of well defined interfaces while offering room to add additional levels of functionality which are complex to handle.
Explanation
GPS system applies abstraction to be able to arrange level of complexity on which a user will interact with the system. For example, it establishes a link of satellite positioned and timed systems to allow a radio receiver obtain a signal in four dimension after synchronizing the data of latitude, longitude, attitude and time.
Base on the question, and in my further computation, the possible answers would be the following and I hope you are satisfied with my answer and feel free to ask for more.
- If you want to determine the Thevenin equivalent voltage and resistance without overloading the battery, then apply some known resistance
<span><span>RL</span><span>RL</span></span> and measure the output voltage as <span><span>VL</span><span>VL</span></span>. Measure the voltage without a load as <span><span>V<span>OC</span></span><span>V<span>OC</span></span></span>. The voltage divider equation tells us that
<span><span><span>VL</span>=<span>V<span>OC</span></span><span><span>RL</span><span><span>R<span>TH</span></span>×<span>RL</span></span></span></span><span><span>VL</span>=<span>V<span>OC</span></span><span><span>RL</span><span><span>R<span>TH</span></span>×<span>RL</span></span></span></span></span>
Solve for <span><span>R<span>TH</span></span><span>R<span>TH</span></span></span>, and you know that <span><span><span>V<span>TH</span></span>=<span>V<span>OC</span></span></span><span><span>V<span>TH</span></span>=<span>V<span>OC</span></span></span></span>.
Answer:
c. Users can have calls forwarded from anywhere in the world
Explanation:
As all you need is the internet, there would be no need to try to sort out roaming as you would on a regular phone line
The answer is the Quick Access Toolbar. However, it is not only for saving files or undoing your work. Containing a set of commands that are independent, this toolbar is actually customizable wherein you could change these icons to the ones you really need and frequently use. By tweaking the settings, you can even add commands to the Quick Access Toolbar that are not in the ribbon (like New, Open and Print).
Answer:
Port number is used at the transport layer to identify the receiving application
Explanation:
Transport layer is responsible for overall “end-to-end” communication. It provides communication service to the application process which might be running on “different hosts”.
TCP (Transmission Control Protocol) or UDP (User Data Protocol) is the protocol used in the Transport layer. The port number is essential so that the transport layer can carry packets to the right destination pointing to the right application.
A port number usually contains 16 bit integer. Normally this number will send along with the header. Port number plays a major role in Transport layer.
