1.)
<span>((i <= n) && (a[i] == 0)) || (((i >= n) && (a[i-1] == 0))) </span>
<span>The expression will be true IF the first part is true, or if the first part is false and the second part is true. This is because || uses "short circuit" evaluation. If the first term is true, then the second term is *never even evaluated*. </span>
<span>For || the expression is true if *either* part is true, and for && the expression is true only if *both* parts are true. </span>
<span>a.) (i <= n) || (i >= n) </span>
<span>This means that either, or both, of these terms is true. This isn't sufficient to make the original term true. </span>
<span>b.) (a[i] == 0) && (a[i-1] == 0) </span>
<span>This means that both of these terms are true. We substitute. </span>
<span>((i <= n) && true) || (((i >= n) && true)) </span>
<span>Remember that && is true only if both parts are true. So if you have x && true, then the truth depends entirely on x. Thus x && true is the same as just x. The above predicate reduces to: </span>
<span>(i <= n) || (i >= n) </span>
<span>This is clearly always true. </span>

Explanation:
A packet filter firewall is used as a check point between internal corporate network to the outside internet. It blocks all the inbound traffic from the outside hosts trying to initiate a direct TCP connection to the internal corporate webserver. The network design with firewall is shown in the attached image below:
The figures in the attached image below shows an internal corporate network is protected with a packet filter firewall to minimize the inbound traffic from the external network or an internet. Therefore, the packet filter is used as a check point between the network.
The packet filter blocks all attempts by the outside hosts in order to initiate a direct TCP connection to the internal webserver of the internal corporate network.
Going by the second part of the attached image below can can therefore conclude that:
• Rule 1 specifies that, deny any packet with the destination address 5.6.7.8 if the STN flag of TCP header is set.
• Rule 2 specifies that, allow the inbound email traffic from the external source.
• Rule 3 specifies, allows the Outbound TCP traffic from the internal corporate network.
• Rule 4 specifies, allows outbound Email traffic from the internal corporate network to the external network.
• Rule 5 specifies, block any traffic from any source to the any destination.
Answer:
Option B is the correct answer for the above question
Explanation:
XHTML is an advanced version of HTML language which is recommended by W3C. It set the standard in 26-JAN-2000 for the XHTML which belongs to the family of HTML. XHTML is made with the help of XML and also used like XML. It used to create more secure websites.
The Above question asked about the W3C recommendation but the above paragraph described that XHTML is a W3C recommendation. Hence Option B is the correct choice answer. while the other is not because--
- Option A suggests HTML 4.01 which is the updated version of HTML only.
- Option C suggests XML which is used to data transfer only.
- Option D suggests about DHTML but XHTML is a W3C recommendation
