Expert Solution & Answer
Chapter 8, Problem 1RQ
Program Description Answer
Viewport is the visible area of a webpage for a user . The Meta tag used to configure display for mobile devices is Viewport.
Hence, the correct answer is option “A”.
Expert Solution & Answer
Explanation of Solution
Tag used to configure mobile devices:
- The webpages designed for computer resolution cannot be viewed the same way on a mobile device.
- Once the viewport tag is configured, the page can be zoomed and scaled to a width that is easy for a user to read.
- The “<meta>” tag is used to let web designers take control over the viewport.
In HTML 5, it can be used as:
<meta name="viewport" content="width=device-width, initial-scale=1.0">
Here,
- The “<meta>” gives instructions to the browser to control the page dimension and scaling.
- “width=device-width” is used to set the width of the page similar to the screen width of the mobile device.
- The “initial-scale=1.0” sets the zoom level when the browser loads the page.
Explanation for incorrect options:
Handheld:
Handheld value informs the server that the user has optimized the page and the optimized version can be viewed using a mobile device. It is not used to configure display for mobile devices.
Hence, option “B” is wrong.
Mobile:
There is no mobile tag present in HTML to configure display for mobile devices.
Hence, option “C” is wrong.
Screen:
There is no screen tag present in HTML to configure display for mobile devices.
Hence, option “D” is wrong.

- If a UDP datagram is sent from host A, port P to host B, port Q, but at host B there is no process listening to port Q, then B is to send back an ICMP Port Unreachable message to A.

(b) Find out what an application has to do, on the operating system of your choice, to receive such messages.

Our problem is a 2x2 binary sudoku, which in our case has two simple rules: •No column may contain the same value twice •No row may contain the same value twice If we assign each square in our sudoku to a variable like so: 1 V V₁ V3 V2 we want our circuit to output a solution to this sudoku. Note that, while this approach of using Grover's algorithm to solve this problem is not practical (you can probably find the solution in your head!), the purpose of this example is to demonstrate the conversion of classical decision problems into oracles for Grover's algorithm. Turning the Problem into a Circuit We want to create an oracle that will help us solve this problem, and we will start by creating a circuit that identifies a correct solution, we simply need to create a classical function on a quantum circuit that…arrow_forward
