Why do the optical signals used in optical fibre cables have a
very short wavelength?​

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.

Answer:

In Python:

file = open('steps.txt', 'r')

readLine = file.readlines()

begin = 0

mdays = (31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31)

print("Month"+"\t\t"+"Average Steps")

for m in range(len(mdays)):

end = begin + mdays[m]

steps = readLine[begin:end]

sumsteps = 0

for s in steps:

 sumsteps = sumsteps + int(s)

average = round(sumsteps/mdays[m],1)

print(str(m+1)+"\t\t"+str(average))

begin = begin + mdays[m]

Explanation:

This line opens the step.txt file

file = open('steps.txt', 'r')

This reads the content of the file

readLine = file.readlines()

begin = 0

This initializes the months of the days to a tuple

Mmdays = (31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31)

This prints the header

print("Month"+"\t\t"+"Average Steps")

This iterates through the tuple

for m in range(len(Mmdays)):

This calculates the days in each month

end = begin + Mmdays[m]

This gets the number of steps in each month

steps = readLine[begin:end]

This initializes the number of steps to 0

sumsteps = 0

This iteration sums up the number of steps in each month

for s in steps:

 sumsteps = sumsteps + int(s)

This calculates the average of steps rounded to 1 decimal place  

average = round(sumsteps/Mmdays[m],1)

This prints the calculated average

print(str(m+1)+"\t\t"+str(average))

This calculates the beginning of the new month

begin = begin + Mmdays[m]

Answer:

Explanation:Reinforcement Learning(RL) is a type of machine learning technique that enables an agent to learn in an interactive environment by trial and error using feedback from its own actions and experiences.

In Reinforcement Learning, algorithms that learn from trial and error are called as long term reward.

Reinforcement learning are defined as a branch of machine learning that looks at how intelligent agents should behave in a given situation to maximize the idea of cumulative reward. In order to optimize the "reward function" or other user-provided reinforcement signal that builds up from the immediate rewards, the agent uses reinforcement learning to develop an optimal or nearly optimal strategy.

Long term rewards are defined as a corporate policy that pays staff for achieving defined objectives that boost shareholder value. Without using a world model, learn how to plan out scenarios and behaviors to maximize long-term gain.

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.

Explanation:

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);  

}

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.

Answer:

The answer is below

Explanation:

Suppose end system A wants to send a large file to end system B, the large file is first divided into smaller chunks. Each chunk is then assigned a header forming a packet. Multiple packets are being generated with each of the packet containing a unique destination address in its header.

When a packet arrives at the packet switch, the switch uses the unique destination address that is attached in the header of the packet to determine the link onto which the packet is to be forwarded.
