Is a program that disguises itself as an interesting?
A Trojan Horse is a malicious program that disguises itself as a useful, harmless program.
Which of the following is a program that enters a computer system disguised as a desirable program?
Trojan horse
A Trojan horse, or “Trojan”, enters your system disguised as a normal, harmless file or program designed to trick you into downloading and installing malware.
Which type of malware consists of a fully contained program that self replicates and spreads through computers and networks?
Also called Ransomware. type of malware that self-replicates and spreads through computers and networks. Unlike a virus, a worm is a fully contained program that is not attached to a host file.
What is used to prevent attenuation?
One of the techniques that can be used to increase signal strength to prevent attenuation is amplification. Signal amplification electrically increasing the strength of a line signal by one of several technical methods.
Is a computer program that can copy itself and infect a computer?
Definition(s): A computer program that can copy itself and infect a computer without permission or knowledge of the user. A virus might corrupt or delete data on a computer, use e-mail programs to spread itself to other computers, or even erase everything on a hard disk.
Is a program that gathers information about your surfing?
Spyware can collect almost any type of data, including personal information like internet surfing habits, user logins, and bank or credit account information.
Why is attenuation important?
Attenuation is an important factor limiting the transmission of a digital signal across large distances. Thus, much research has gone into both limiting the attenuation and maximizing the amplification of the optical signal.
How can attenuation be prevented or improved?
Including Amplifiers or Repeaters
Although repeaters or amplifiers may slow down a signal, they do a great job at preventing attenuation. These options may work best in large offices or environments where the signal needs to reach farther, but the speed of the transmission is less important.
Which of the following is the best solution to the attenuation problem?
Which of the following is the best solution to the attenuation problem? Segment the cable with repeaters. Which RG standard is used for long distance drops and underground cables?
What is attenuation effect?
Attenuation effects refer to the fact that an observed correlation coefficient will tend to underestimate the true magnitude of the relationship between two variables to the extent that these measures are not an accurate reflection of true variation, i.e., to the extent that they are unreliable.
Why does frequency increase attenuation?
Figure 1: Attenuation of a signal through a low pass filter increases as the signal frequency increases. … The signal above frequency F1 is increasingly absorbed. The signal attenuation below frequency F1 is not linear, but close enough at a level of less than 1 dB of attenuation.
What is another word for attenuation?

What does the correction of attenuation look at?
The correction for attenuation tells one what the estimated correlation is expected to be if one could measure X′ and Y′ with perfect reliability.
What does attenuated mean in research?
Attenuation is a statistical concept that refers to underestimating the correlation between two different measures because of measurement error. Because no test or other measurement of any construct has perfect reliability, the validity of the scores between predictor and criterion will decrease.
What causes attenuation?
Attenuation is the reduction in power of the light signal as it is transmitted. Attenuation is caused by passive media components, such as cables, cable splices, and connectors. … Dispersion is the spreading of the signal over time.
What does the correction of attenuation look at quizlet?
The correction for attenuation formula is used to estimate what the correlation would have been if the variables had been perfectly reliable.
What is measurement error bias?
Bias. Systematic, or biased, errors are errors which consistently yield results either higher or lower than the correct measurement.
What is correlation between variables?
The statistical relationship between two variables is referred to as their correlation. A correlation could be positive, meaning both variables move in the same direction, or negative, meaning that when one variable’s value increases, the other variables’ values decrease.
What is validity consistency?
Reliability and validity are concepts used to evaluate the quality of research. They indicate how well a method, technique or test measures something. Reliability is about the consistency of a measure, and validity is about the accuracy of a measure.
What is internal consistency reliability in research?
Internal consistency reliability is a way to gauge how well a test or survey is actually measuring what you want it to measure. … You send out a survey with three questions designed to measure overall satisfaction. Choices for each question are: Strongly agree/Agree/Neutral/Disagree/Strongly disagree.
What is internal consistency in research?
Internal consistency assesses the correlation between multiple items in a test that are intended to measure the same construct. You can calculate internal consistency without repeating the test or involving other researchers, so it’s a good way of assessing reliability when you only have one data set.
How can you improve reliability?
5 Ways to Boost Your Personal Reliability
- Manage Commitments. Being reliable does not mean saying yes to everyone. …
- Proactively Communicate. Avoid surprises. …
- Start and Finish. Initiative and closure are the bookends of reliability and success. …
- Be Truthful. …
- Respect Time, Yours and Others’.
How can you improve accuracy?
The best way to improve accuracy is to do the following:
- Read text and dictate it in any document. This can be any text, such as a newspaper article.
- Make corrections to the text by voice. For more information, see Correcting your dictation.
- Run Accuracy Tuning. For more information, see About Accuracy Tuning.
