1. Increase QoS
Explanation:
The radio bands with lower frequency have relatively large wavelengths that are not as affected by objects such as building, trees, weather events or other features in the troposphere as the higher frequency radiation. General rule for radiation is that the lower the frequency, i.e. the longer the wavelength, the further a signal can penetrate through solid objects or liquids. Hence, when the frequency is lowered on a wireless access point, the signals can travel farther and smoother. Thus, increasing the quality of service.

A short-circuit evaluation is where each part of an expression is evaluated only as far as necessary to determine whether the entire expression is:_____.A. True B. false
Answer:
The correct answer is True.
Explanation:
Short circuit evaluation is the semantics of some Boolean operators in some programming languages in which the second argument is executed or only evaluated if the first argument is not sufficient to determine the value of the expression: when the first argument of the AND function evaluate to false, the global value must be false; and when the first argument of the OR function evaluates to true, the global value must be true. In some programming languages (Lisp, Perl, Haskell, due to lazy evaluation), the usual Boolean operators are short-circuited. In others (Ada, Java), both short-circuit and standard Boolean operators are available. For some Boolean operations, such as exclusive or (XOR), a short circuit is not possible, because both operands are always necessary to determine the result.
What is the faster way for browsers to obtain the revocation status of a digital certificate attached to a Web site?
Answer:
The fastest way to obtain the revocation status of digital certificate of the website is by using Online certificate Status Protocol (OSCP).

Since IP addresses are difficult to remember, you want to implement a protocol on your network that allows computers to automatically find another host's IP address using a logical name. True or false?
Answer:
False
Explanation:
Using subnet mask will be helpful, what the subnet mask does is moving the IP address boundary bettween the part that represents a network and the part that represents a host, thus, instructing the operating system which IP addresses are on the local subnet. Then the operating will communicate directly with the other host without using the router. Once this is achieved, memorizing the IP addresses is needless.
The Domain Name System (DNS) is the protocol that allows computers to use logical names instead of numerical IP addresses to find and connect to other hosts on the Internet. It is essential for the usability of the web, translating names to IP addresses.
Explanation:The protocol you want to implement to allow computers to automatically find another host's IP address using a logical name is the Domain Name System (DNS). This system translates more memorizable domain names to the numerical IP addresses needed for locating and identifying computer services and devices with the underlying network protocols. DNS is an essential component of the functionality of the Internet, providing a way to match names (a website you're seeking) to numbers (the address for the website). Anything connected to the Internet - laptops, tablets, mobile phones, websites - has an Internet Protocol (IP) address made up of numbers. Your request to connect to a site is sent to the DNS server, and the DNS server responds with the corresponding IP address. Thus, users don't need to memorize IP addresses; they simply remember the domain name, which is then resolved into an IP address by the DNS server.
You’re trying to cast a video presentation from your tablet to a projector for a training session with some new hires. Although you tested it successfully yesterday, today the connection is not cooperating. You’ve closed apps you’re not using, and you’ve checked that the projector and the tablet are working otherwise. Of the following troubleshooting steps, which should you try first? Second?

Based on the information provided within the question it can be said that of the following troubleshooting steps you should first try to Restart the tablet. Many times a background process gets stuck and is preventing the connection from establishing. If this does not work then the next step would be to restart the projector, and lastly Verify that you have Internet access on the tablet.
Final answer:
First, verify Internet access on the tablet for casting the presentation. If connectivity is fine, then restart the tablet to solve potential glitches. Reinstalling the app is the last step after attempting simpler solutions.
Explanation:
When faced with technical difficulties while trying to cast a presentation from a tablet to a projector, it's essential to approach the situation methodically to identify and solve the issue. The first step to troubleshooting is to verify that you have Internet access on the tablet, as some presentations may require an online connection, especially if using web-based software like Prezi. If the Internet connection is stable, then the next step is to restart the tablet. This action can resolve many temporary glitches that may prevent the device from communicating correctly with the projector.
If these steps do not rectify the issue, proceed by restarting the projector, which may reinitialize the connection between the devices. Reinstalling the presentation app should be the last resort, as it is more time-consuming and typically unnecessary if the app was working the day before.

Suppose that a Web server runs in Host C on port 80. Suppose this Web server uses persistent connections, and is currently receiving requests from two different Hosts, A and B. Are all of the requests being sent through the same socket at Host C?
Answer:
No.
All the requests are not being sent through the same socket as host C.
Explanation:
For every of the persistent connections, the web server creates a separate connection socket.
The various connection sockets created, are identified using the following four details:
source IP address, source port number, destination IP address, destination port numberWhen port C receives an IP datagram, it examines these four fields in the datagram to determine which socket to pass the payload of the Transmission Control Protocol (TCP) segment. The TCP works with the Internet Protocol (IP), which defines how computers send packets of data to each other.
Requests from hosts A and B will pass through different ports. This is because although they have the same destination port of 80, they have different source IP addresses, due to the fact that they are from different hosts.
The two requests will pass through different sockets because they have different values for source IP addresses.

Use the fundamental counting principle to solve the problem. How many different codes of 4 digits are possible if the first digit must be 3, 4, or 5 and if the code may not end in 0?
Answer and Explanation:
Given,
4 digits and 10 digits.
Firstly, we have to find that when it repeats the digit then
First position code would be filled in by Three methods that is 3, 4, or 5.Second position code would be filled in by Ten methods.Third position code would also be filled in by Ten methods.Fourth position code would be filled in by 9 way but 0 is rejected. So, the total numbers of methods in the following case is [tex]3\times10\times10\times 9=2700[/tex].Then, we have to find that when it not repeats the digit then
First position code would be filled in by Three methods that is 3, 4, or 5.Second position code would be filled in by Nine methods in which one is reserved earlier.Third position code would be filled in by Eight methods in which two are reserved earlier.Fourth position code would be filled in by Six methods in which three are reserved earlier.So, the total numbers of methods in the following case is [tex]3\times9\times8\times6=1296[/tex]The fundamental counting principle can be used to determine the number of different codes of 4 digits that are possible, given certain conditions. In this case, there are 3 choices for the first digit, 10 choices for the remaining three digits (excluding 0 for the last digit), resulting in a total of 2,700 possible codes.
Explanation:The problem asks for the number of different codes of 4 digits that are possible if the first digit must be 3, 4, or 5, and if the code may not end in 0.
Using the fundamental counting principle, we consider each digit of the code separately. For the first digit, we have 3 choices (3, 4, or 5). For the remaining three digits, we have 10 choices each, as any digit from 0 to 9 can be chosen. However, since the code may not end in 0, we have 9 choices for the last digit.
Applying the multiplication principle, we multiply the number of choices for each digit: 3 choices for the first digit, 10 choices for the second, third, and fourth digits, and 9 choices for the last digit. Therefore, the total number of different codes is 3 x 10 x 10 x 9 = 2,700.

Suppose Host A wants to send a large file to host B. The path from Host A to Host B has three links, of rates R1 = 500 kbps, R2=2 Mbps, and R3 = 1 Mbps. Assuming no other traffic in the network, what is the throughput for the file transfer? 500 kbps
Answer:
The answer is 500 kbps
Explanation:
Consider the given data in the question.
R1 = 500 kbps
R2=2 Mbps
R3 = 1 Mbps
Now as it is mentioned that there is no other traffic in the network.
Thus,
throughput of the file = min {R1,R2,R3}
throughput of the file = min {500 kbps, 2 Mbps, 1 Mbps}
T/P of the file = 500 kbps
