What should you do before you install a third-party anti-malware program?

An algorithm to compute the mean value of all odd numbers between 1 to 500 inclusive is: sum = sum + i count = count + 1 mean = sum / count return mean

Here is an algorithm to compute the mean value of all odd numbers between 1 to 500 inclusive:

1. Initialize a variable called 'sum' to 0

2. Initialize a variable called 'count' to 0.

3. Loop through all the odd numbers from 1 to 500 inclusive.

4. For each odd number, add it to the 'sum' variable and increment the 'count' variable by 1.

5. After the loop, divide the 'sum' variable by the 'count' variable to get the mean value.

6. Return the mean value as the output.

Here's what the algorithm would look like in pseudocode:

sum = 0 count = 0 for i from 1 to 500 inclusive:

if i is odd:

sum = sum + i count = count + 1 mean = sum / count return mean

Answer:

The social and ethical consequences of emerging technology are hard to predict since it is truly impossible to see how technology will be applied to situations that have not really occurred yet.  

Explanation:

One-time Password Algorithm option B, "The server is not configured with a counter in HOTP" is the correct answer.

The problem that exists with the HMAC-based One-time Password Algorithm (HOTP) that is addressed by the Time-based One-time Password Algorithm (TOTP) is the vulnerability to replay attacks.

HOTP is a one-time password algorithm that generates a unique password based on a shared secret key and a counter value. The shared secret key is known to both the server and the token, and the counter value is incremented each time a password is generated to ensure that each password is unique. However, if an attacker intercepts a password and replays it before the counter value changes, they can gain unauthorized access to the system.

In contrast, TOTP is also a one-time password algorithm, but instead of using a counter value, it uses a timestamp to generate a unique password. The password generated by TOTP is based on the current time and the shared secret key. The server and the token both use the same time interval, typically 30 seconds, to generate the password. This ensures that each password is only valid for a limited period, and replay attacks are less likely to succeed.

The use of a time-based counter in TOTP adds an extra layer of security and reduces the likelihood of replay attacks. This is because the password generated based on the current time will expire after the time interval has elapsed, making it more challenging for an attacker to reuse the password.

The two types of signals used to communicate a message in a network are digital signals and analog signals. These signals differ from each other in their properties, structure, and other features.Keep on reading to know how digital and analog signals differ from each other.

1. Digital SignalsA digital signal is a representation of data using a binary code system consisting of 0s and 1s. These 0s and 1s represent the OFF and ON states of a signal. The digital signal can transmit information over long distances with minimal distortion. In digital signals, the data is in the form of discrete signals. The processing of digital signals is faster and more efficient. Digital signals provide better error correction and noise reduction. Some of the examples of digital signals include Wi-Fi signals, mobile data signals, etc.

2. Analog SignalsAnalog signals are continuous signals that change continuously over time. These signals are represented by sine waves. Analog signals can transmit information over short distances. Analog signals are not efficient in terms of error correction and noise reduction. They are also more prone to distortion. Analog signals are used in old technologies like landline telephones, radio signals, and television signals.These are the two types of signals used to communicate a message in a network, and they differ in terms of their properties, structure, and efficiency.

Explanation:

took this last year

Answer:

a. The time it will take for the two robots meet

b. The important numbers are;

426 (cm), 5 (cm/second) and 7 (cm/second)

c. Yes, there are variables

d. The equation is 5 cm/s × t + 7 cm/s × t = 426 cm

e. The solution of the equation is, t = 35.5 seconds

f. Yes, the answer is reasonable

Explanation:

a. The question being asked is the time duration that will elapse before the two robots meet

b. The important numbers are;

The distance apart from which the two robots start out, d = 426 cm

The  speed of the first robot, v₁ = 5 cm/second

The  speed of the second robot, v₂ = 7 cm/second

c. The variables are;

The distance apart of the two robots = d

The  speed of the first robot = v₁

The  speed of the second robot = v₂

The time it takes for the two robots to meet = t

d. The equation is;

v₁ × t + v₂ × t = d

Plugging in the known values of v₁, v₂, we have;

5 cm/s × t + 7 cm/s × t = 426 cm...(1)

e. Solving the equation (1) above gives;

5 cm/s × t + 7 cm/s × t = t × (5 cm/s + 7 cm/s) = t × 12 cm/s = 426 cm

∴ t = 426 cm/(12 cm/s) = 35.5 s

t = 35.5 seconds

f. The time it would take the two robots to meet, t = 35.5 seconds

The answer is reasonable, given that the distance moved by each robot in the given time are;

The distance moved by the first robot, d₁ = 35.5 s × 5 cm/s = 177.5 cm

The distance moved by the second robot, d₂ = 35.5 s × 7 cm/s = 248.5 cm

d₁ + d₂ = 177.5 cm + 248.5 cm = 426 cm.

From the readings for this week, the term "hacker" has evolved since the 1950s as follows:In the 1950s and 1960s, hackers were seen as individuals who used their technical skills to develop software solutions to problems they encountered.

The computer security systems were not as strong as they are today, so hacking was more of a skill than a criminal activity.In the 1970s and 1980s, computer hacking began to gain recognition as a criminal activity, thanks to a number of high-profile cyber attacks.

The government, corporations, and private organizations began to pay more attention to computer security, and hacking began to be viewed as a serious threat

.In the 1990s, the public became more aware of hacking due to the increased use of the Internet. Hacking evolved from being just a hobby for computer enthusiasts to a full-blown criminal enterprise with the potential to cause significant damage and financial loss.

Three "low-tech" methods that hackers have used to obtain login names and passwords include the following:

1. Shoulder surfing: This is a technique used by hackers to observe and record login credentials by standing near the target and watching them type in their login information.

2. Dumpster diving: This involves searching through a target's trash for documents or papers containing login information

.3. Phishing: This is a social engineering technique in which hackers use emails or messages to trick the target into revealing their login information.

what is confidence interval?

confidence interval represents the accuracy of a particular estimation.

what is proportion of sample?

proportion of population is the ratio of random sample to the total available sample.

Given, size of samples that means number of total iPhones, n = 25

size of random samples that means iPhone with 85 downloaded apps, p= 12,

critical value for 90% confidence interval z* = 1.65

proportion of samples, p^ = p/n = 12/25 =0.48

finally, confidence interval = p^±z*[√{p^(1-P^)/n}]

At pH 7.0, the carboxyl group of glutamic acid (Glu) in Arg-Glu-Met (V) and the carboxyl group of aspartic acid (Asp) in Ala-Thr-Asn (II) are deprotonated, resulting in a net negative charge. On the other hand, the side chain of lysine (Lys) in Leu-Lys-Gly (IV) has an amino group that can accept a proton at pH 7.0, resulting in a net positive charge. Therefore, out of the options given, Leu-Lys-Gly (IV) is the tripeptide that carries a net positive charge at pH 7.0.

Here is a summary:

- Gln-Val-Ser (I) does not contain any charged amino acids and therefore does not carry a net positive charge at pH 7.0.

- Ala-Thr-Asn (II) contains aspartic acid (Asp), which has a deprotonated carboxyl group and carries a net negative charge at pH 7.0.

- Pro-Ile-Leu (III) does not contain any charged amino acids and therefore does not carry a net positive charge at pH 7.0.

- Leu-Lys-Gly (IV) contains lysine (Lys), which has an amino group that can accept a proton at pH 7.0, resulting in a net positive charge.

- Arg-Glu-Met (V) contains glutamic acid (Glu), which has a deprotonated carboxyl group and carries a net negative charge at pH 7.0
