Answer and Explanation:
Given data:
Distance (D) = 40 KM
Speed of light in the fiber =Distance/ speed of light in the fiber
a) Delay (P) = Distance/ speed of light in the fiber
= (40,000 Meters/2×108 m/s)
=( 40×103 Meters/2×108 m/s)
Propagation delay (P) = 0.0002 seconds or 200 microseconds
b)
if propagation delay is 0.0002 Seconds roundup trip time (RTT) will be 0.0004 Seconds or 400 micro Seconds
Essentially since transmission times and returning ACKs are insignificant all we really need is a value slightly greater than 0.0004 seconds for our timeout value.
c)
The obvious reasons would be if the data frame was lost, or if the ACK was lost. Other possibilities include extremely slow processing on the receive side (late ACK).
Or Extremely Slow Processing of the ACK after it is received back at the send side.
Option A is true because IP is short form of Internet protocol.
Option B is true because when every device is connected to the servers by using internet, Internet Service providers assign them unique IP address to define their identity on internet and monitor their activities.
Option C is false because no matter how many laptops or devices are connected to a same router through a network Internet Service Providers assign them a same IP address.
Option D is true because every laptop or device connected to the internet by a network is given the same public IP or external IP.
Answer:
The Correct syntax for inserting an image as hyperlink is given in explanation section
Explanation:
To make an image act as a hyperlink, place the image element within the HTML anchor "<a></a>" element.
The syntax of inserting image hyperlink in XHTML is given below.
<a href = "link_that_can_be_accessible"><img src="source of image" alt="display name if image not shown in the browser" border="0"/></a>
for example lets insert image as hyperlink
<a href="ajax.html"><img src="logo.gif" alt="AJAX" border="0" /></a>
The default appearance is a blue border around the image. Specifying border="0" removes the border around the image.
if you want to insert image from another folder then the image hyperlink looks like this:
<a href="ajax.html"><img src="/images/html5/logo.gif" alt="AJAX" border="0" /></a>
If you want to insert image from another server then image hyper link looks like this:
<a href="ajax.html"><img src="https://www.myExample.com/images/html5/logo.gif" alt="AJAX" border="0" /></a>
