Which popular VPN protocol allows segment access for users?
IPsec
PPTP
L2TP
SSL VPN
Answer:
SSL VPN
Explanation:
Secure Sockets Layer, or SSL VPN, is the second common VPN protocol.
A big plus for SSL VPNs is that they can allow segmented access for users. For example, users can be limited to checking email and accessing shared drives rather than having access to the entire network.
SSL VPNs come in two types, SSL portal and SSL tunnel.
SSL Portal VPNs
SSL Portal VPNs allow a user to securely access the web from a browser once the user logs into the VPN’s online portal using a specified method of authorization.
This type of SSL VPN gets its name because of how the user accesses it – through a single web page, or portal. The page acts as a single gateway to the other services available on the secured network.
SSL Tunnel VPNs
SSL Tunnel VPNs allow the user to not only access the web securely, but to also use applications and other network services that aren’t based on the web.
Due to their sophisticated segmentation capabilities, SSL VPNs often require more skill to implement.
VPNs are not a cure-all
Of course, what you could do is circumvent the entire debate around VPN SSL vs IPSEC. Our Gatekeeper offering is an enhanced alternative to VPN with no client, that still offers two-factor authentication to secure remote access.
Wherever you land between VPN SSL vs IPSEC, of if you join #TeamGatekeeper, having one of these tools to protect web traffic is a great way to help secure information, but it’s not an end-all be-all security solution.
After all, a VPN won’t protect your employees from social engineering attacks such as email phishing.

Hint: if your roll no is 33 then your ip address will look like this: 33.33.33.33/20
Answer:
If there’s one topic that trips people up (both new and experienced) in the networking industry, it is that of Subnetting.
One of the reasons this happens is that one has to perform (mental) calculations in decimal and also binary. Another reason is that many people have not had enough practice with subnetting.
In this article, we will discuss what Subnetting is, why it came about, its usefulness, and how to do subnetting the proper way. To make this article as practical as possible, we will go through many examples.
Note: While subnetting applies to both IPv4 and IPv6, this article will only focus on IPv4. The same concepts explained here can be applied to IPv6. Moreover, subnetting in IPv6 is more of a want rather than a necessity because of the large address space.
IP address network
For example, any traffic with a destination IP address of 192.168.1.101 will be delivered to PC1, while traffic addressed to 192.168.1.250 will be delivered to SERVER.
Note: This is an oversimplification of things just for understanding sake and refers to Unicast (one-to-one) IPv4 addresses. Traffic sent to Multicast (one-to-many) and Broadcast (one-to-all) IP addresses can be delivered to multiple devices. Also, features like Network Address Translation (NAT) allow one IP address to be shared by multiple devices.
To help your understanding of IP addresses and subnetting, you need to resolve the following fact in your head: Computers think in binary, that is, 0s and 1s. Therefore, even though we see an IP address represented like 192.168.1.250, it is actually just a string of bits – 32 bits in total for IPv4 addresses.
To make them more readable for humans, IPv4 addresses are represented in dotted decimal notation where the 32 bits are divided into 4 blocks of 8 bits (also known as an octet), and each block is converted to a decimal number.
For example, 01110100 in binary is 116 in decimal:
A unicast IPv4 address such as 192.168.1.250 can be divided into two parts: Network portion and Host ID. So what does this mean? Well, IPv4 addresses were originally designed based on classes: Class A to Class E. Multicast addresses are assigned from the Class D range while Class E is reserved for experimental use, leaving us with Class A to C:
Class A: Uses the first 8 bits for the Network portion leaving 24 bits for host IDs. The leftmost bit is set to “0”.
Class B: Uses the first 16 bits for the Network portion leaving 16 bits for host IDs. The two leftmost bits are set to “10”.
Class C: Uses the first 24 bits for the Network portion leaving 8 bits for host IDs. The three leftmost bits are set to “110”.
Note: The range of Class A is actually 1-126 because 0.x.x.x and 127.x.x.x are reserved.
With these classes, a computer/device can look at the first three bits of any IP address and determine what class it belongs to. For example, the 192.168.1.250 IP address clearly falls into the Class C range.
Looking at the Host ID portion of the classes, we can determine how many hosts (or number of individual IP addresses) a network in each class will support. For example, a Class C network will ideally support up to 256 host IDs i.e. from 00000000 (decimal 0) to 11111111 (decimal 255). However, two of these addresses cannot be assigned to hosts because the first (all 0s) represents the network address while the last (all 1s) represents the broadcast address. This leaves us with 254 host IDs. A simple formula to calculate the number of hosts supported
Explanation: Final answer is Start address: 192.168.58.0 + 1 = 192.168.58.1
End address: 192.168.58.16 – 2 = 192.168.58.14
Broadcast address: 192.168.58.16 – 1 = 192.168.58.15

When a program is adapted to run on multiple processors in a multiprocessor system, the execution time on each processor is comprised of computing time and the overhead time required for locked critical sections and/or to send data from one processor to another. Assume a program requires t = 100 s of execution time on one processor. When run p processors, each processor requires t/p s, as well as an additional 4 s of overhead, irrespective of the number of processors. Compute the per-processor execution time for 2, 4, 8, 16, 32, 64, and 128 processors. For each case, list the corresponding speedup relative to a single processor and the ratio between actual speedup versus ideal speedup (speedup if there was no overhead).
Exercise 3.7.1: Proving statements about odd and even integers with direct proofs. info About Each statement below involves odd and even integers. An odd integer is an integer that can be expressed as 2k 1, where k is an integer. An even integer is an integer that can be expressed as 2k, where k is an integer.
The question is incomplete. The complete question is :
Each statement below involves odd and even integers. An odd integer is an integer that can be expressed as 2k+1, where k is an integer. An even integer is an integer that can be expressed as 2k, where k is an integer. Prove each of the following statements using a direct proof. (a) The sum of an odd and an even integer is odd. (b) The product of two odd integers is an odd integer.
Solution :
Odd number integers = 2k + 1, where k is integer
Even number integer = 2k
a). Odd integer + even integer
= 2k + 1 + 2k
= 4k + 1
= 2(2k) + 1
Let 2k = t, where t is integer
= 2t + 1
= Odd integer by definition
If number is 2t + 1 where t belongs to integer, then it is odd integer.
Hence proved.
b). Product of two odd integers : [tex]$2k_1 + 1,\ \ 2k_2 +1 $[/tex] where [tex]$k_1, k_2 $[/tex] belongs to integer.
[tex]$(2k_1+1)(2k_2+1)= 4k_1k_2+2k_1+2k_2+1$[/tex]
[tex]$2(2k_1k_2)+2(k_1+k_2)+1$[/tex]
Let [tex]$2k_1k_2 = a$[/tex] and [tex]$k_1+k_2 = b $[/tex]
here, a and b belongs to integers since [tex]$k_1$[/tex] and [tex]$k_2$[/tex] are integers.
We get:
2a+2b+1
= 2(a+b)+1
= 2l + 1, Let (a+b)=l and l belongs to integers.
It is odd integer by definition.
Hence proved.

Answer:I bet your attention automatically tuned into the video background, right? It’s almost impossible to ignore it as it is moving.
There’s nothing wrong with you – it’s just human nature and how we subconsciously decide where to pay our attention to.
We are easily distracted by anything that moves – just like that dog that ignores everything in its world to chase that pesky little squirrel!
“Okay, you got me to look at your silly video, what does this have to do with my website design?”
What a great question and I’m glad you asked.
A video background on your website, if used properly, can help you capture your website visitors’ attention too!
Video background is one of the most popular website design trend that seems to be here to stay.
Marketers love video backgrounds because they make websites look modern and create a sense of artistry that static background images simply can’t match up to.
Many website conversion experts and regular people alike see their visitors stay on their websites longer and more likely to sign up or opt-in to their product / service offers.
I’ll admit – a 138% improvement sounds extraordinary and challenging to achieve every other day.
Keep in mind that such high figure is from tests ran by conversion / business optimization professionals who do this for a living. So it’s fair to say not everybody who runs a DIY website will see similar improvements, just by adding a video background to their website.
However, even a 10% – 20% improvement in engagement and conversion is not unreasonable for even a first-time website owners with no professional help – if you use video background on your homepage the right way!
Imagine if you collected email newsletter subscribers so you can follow up with special promotions or share interesting discussions to build your brand.
Consider what a 20% increase in subscribers can do to your business? This can mean more sales and/or higher brand awareness!
All this can be done if you can capture your visitors’ attention more effectively – by using a video background.
This is not just a hypothetical idea. A lot of real life case studies have demonstrated how many businesses have succeeded by using video backgrounds to improve sales.
Like all things in life, there is a right way and a wrong way of doing things.
Even with something as groundbreaking as a video background, you can still screw it up and end up hurting your overall website design and experience – if you don’t abide by some basic rules.
So, understanding how to avoid basic mistakes when using a video background on your homepage can give you a much higher chance of succeeding in improving your web design.
In this guide, we will show you all the steps and best practices you should take to use video background effectively:Video background is most effective when you use it to (1) create a vibe, (2) to set a tone or (3) to induce an emotional reaction.
Let’s check out some examples:
Example #1: Businesses, Services, Organizations
Video backgrounds work for most professional websites, whether you are running a clinic, consultancy business, or design agency.
You can use a video background to show clips of the life of your staff or even the process of helping a customer. This gives your potential clients a chance to get to know you before even talking to you. It also paints a very vivid visual representation of what they can expect to experience from your business.Grain & Mortar is a design agency. This example is interesting because it shows you that you don’t always need to have a full page video background to get a similar benefit. They only display a video in the header section of the page that takes no more than half the screen real estate.
The video shows the daily collaboration of the staff (strategy sessions) and how they create design solutions for their clients.
At this moment, video background themes are somewhat limited in Shopify’s Theme Store. You do get more selection if you search for Shopify Video Background Themes in third party providers like Themeforest.
Do keep in mind all themes available in Shopify’s Theme Store are screened, approved and supported by Shopify.
In comparison, Shopify Themes from third party providers do not undergo Shopify’s direct screening process. While I am not saying third party themes are not as good, I just want you to be informed if you are considering whether to purchase from a third party provider.

Write a Java program that asks the user to enter an array of integers in the main method. The program should prompt the user for the number of elements in the array and then the elements of the array. The program should then call a method named minGap that accepts the array entered by the user as a parameter and returns the minimum 'gap' between adjacent values in the array. The main method should then print the value returned by the method. The gap
Answer:
In Java:
import java.util.*;
class Main {
public static void minGap(int intArray[], int arrlength) {
if(arrlength <2){return;}
int minm = Math.abs(intArray[1] - intArray[0]);
for (int i = 2; i < arrlength; i++)
minm = Math.min(minm, Math.abs(intArray[i] - intArray[i - 1]));
System.out.print("Minimum Gap = " + minm);
}
public static void main(String arg[]) {
Scanner input = new Scanner(System.in);
int arrlength;
System.out.print("Array Length: ");
arrlength = input.nextInt();
int[] intArray = new int[arrlength];
for(int i = 0;i<arrlength;i++){
intArray[i] = input.nextInt();
}
minGap(intArray, arrlength);
} }
Explanation:
The minGap method begins here
public static void minGap(int intArray[], int arrlength) {
This checks if array length is 1 or 0. If yes, the program returns nothing
if(arrlength <2){return;}
If otherwise, this initializes the minimum gap to the difference between the 0 and 1 indexed array elements
int minm = Math.abs(intArray[1] - intArray[0]);
This iterates through the array elements
for (int i = 2; i < arrlength; i++)
This checks for the minimum gap
minm = Math.min(minm, Math.abs(intArray[i] - intArray[i - 1]));
At the end of the iteration, the minimum gap is printed
System.out.print("Minimum Gap = " + minm);
}
The main method begins here
public static void main(String arg[]) {
Scanner input = new Scanner(System.in);
This declares the length of the array
int arrlength;
This prompts the user for array length
System.out.print("Array Length: ");
This gets the user input
arrlength = input.nextInt();
This declares the array
int[] intArray = new int[arrlength];
The following iteration gets input for the array
for(int i = 0;i<arrlength;i++){
intArray[i] = input.nextInt();
}
This calls the minGap method
minGap(intArray, arrlength);
}

Why do the optical signals used in optical fibre cables have a
very short wavelength?
Answer:
Optical signals have very high frequencies. A high frequency means a short wave length because the wave length is inversely proportional to the frequency (λ = v/f), where v is the propagation speed in the media.
Explanation:
Since optical signals have a greater frequency, measured in nanometers, their wavelengths are shorter (10-9 meter). A billionth of a meter is equal to one nanometer (nm), a unit of length.
What are optical signals?An electromagnetic signal is an optical signal. It has oppositely polarised magnetic and electric fields.
The frequency of this EM pulse is typically very high (in the order of THz). As a result, measuring it in terms of wavelength is more practical.
The frequency of optical communications are very high. Since the wave length and frequency are inversely related, a high frequency implies a short wavelength.
To a receiving end, where the light signal is processed as data, the fiber transfers "data" by light.
As a result, fiber optics serves as a "pipe" or transmission medium for signals that need to travel vast distances quickly.
Thus, the optical signals used in optical fiber cables have a very short wavelength.

determine the factors using computer failures and defects
Answer:
Voltage spike – This is a momentary change in the supply of electric power. It’s important to remember that the size of the transient can range from just milliseconds to longer periods of time. Even a small power glitch can damage a computer and corrupt data. If the screen goes blank during a thunderstorm, it’s likely that a voltage spike is responsible.
Circuit board fails with no visible indication of damage – This is the typical scenario: A computer goes down. A defective circuit board is suspected of the fault, but an inspection reveals no signs of physical damage. A replacement board is installed and operation resumes.
Failure to load software upgrades – Computer software often comes with various bugs, or vulnerabilities. These are simply programming mistakes, but they can make the software susceptible to viruses and glitches. When an error is discovered, the software designer sends out a “patch” that requires downloading and rebooting. Failing to upgrade the software by running the patch can lead to corruption of data.
Failure to keep virus protection up to date – There are several malware protection packages available for computer rooms or data centers. Once installed, the subscription must be maintained. One telltale sign of a malware infected computer is slow data processing.
Inadequate cooling – Computers produce heat, and the more data they process, the more heat must be eliminated. Servers, the “brains” of computers, fail under excess heat, so adequate cooling is essential.
Environment – If a computer room has a dedicated cooling system, there may be an opportunity to closely control the heat. If the cooling is shared with other equipment or the space contains offices, we often face a more challenging task. People have comfort needs different to those of computers.
Loss of Power, PDU fails – Power Distribution Units (PDU’s) are similar to power bars in homes and offices. They distribute power to different components in a computer room, and are usually located next to the server racks. PDU’s suffer a range of problems. Receptacles wear out and can be the sources of bad contacts, and moisture can lead to corrosion.
UPS batteries – Uninterruptible Power Supply (UPS) batteries are found in computer rooms. Most often, they are used to provide continuous power for a limited time, during an outage. Depending on how it’s used and the design of the battery, the life span can be as short as 4-5 years for what is considered a “10 year life” battery. Elevated room temperatures will shorten the life of any battery. Even a small facility such as a dentist office uses UPS batteries.
Transfer switch battery defective – This can be an indication that the site lacks an effective battery maintenance program. It can also be a sign that the transfer switch is “frozen” in position. Preventive maintenance could help avoid a breakdown.
Failure of standby power to synchronize (come on line) – When electric power from the grid disappears, standby power takes over in two different ways. In a small computer room, the focus is on turning computers off in a controlled manner. A fully charged UPS will provide power for 10-15 minutes to allow a computer to save its data and turn off. In a larger facility, it’s the matter of keeping cooling and power going long enough to give the standby generator an opportunity to “synchronize,” to get up to a rate of speed sufficient to power the infrastructure and continue data processing.
Diesel fuel contaminated – Most medium to large facilities have generators powered by diesel fuel, which can become contaminated and useless when a power outage occurs. Water is usually the culprit. Regular fuel testing is necessary to avoid contamination.
Storage defective – Data is stored on magnetic disks or tape. Both can be damaged during normal operation, so it’s a good practice to back up stored data on a regular basis. Backing up means creating a spare data storage. Failure of a tape or disk drive is often, but not always, proceeded by noise. Opening the unit to attempt data restoration is better left to a professional.
Sprinkler system turns on above the servers – Where a data room is protected by a water sprinkler system, a small spill can damage the electronic components. This is particularly true in cases where sprinkler heads are located directly above the servers.
Computers are crucial to business today, but there are so many things that can cause them to fail. By addressing the above common culprits, you could help reduce the overall risk of your computer systems failing.
