Answer:

Line graphs allow us to see overall trends such as an increase or decrease in data over time. Bar graphs are used to compare facts.

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.

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.

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);  

}

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.

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.

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.

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.

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