What is binary number system? Why is it used in computer system?
Answer:
Computers depend mainly on binary because it’s more time efficient for them to so.
Explanation:
It’s easier to identify 0 as “off” and 1 as “on”. As you may know, transistors are the fundamental blocks of microprocessors and ICs. The reasons this is the case is that these transistors form logic gates which can carry out basic logic operations. These logic gates are a huge step into making microprocessors/ICs/etc. And what do these logic gates depend on? They depend on binary.
Whoa whoa, wait a minute. Let’s first take a step back to know a thing or two about logic gates.
These logic gate can be constructed from transistors. They carry basic logic operations. You have one or more inputs “entering” the logic gate ——-> A certain operation is performed on them ——-> you get your output. The input is a voltage. This voltage it can be interpreted as an “on” or “off” according to the gate. Once again these offs and ons are 0s and 1s. For example the Inverter/NOT gate is a gate that simply takes an input and gives its inverse. For example:-
A low voltage/an “off” signal/ a “0” “enters” the NOT gate. ——-> A high voltage/an “on” signal/ a “1” is the result of the operation performed
(In the above example low voltage = “off” signal = 0, high voltage = “on” signal = 1)
As you can see, a 0 enters the NOT gate and a 1 comes out or vice versa. Now, if you were a logic gate, you’d prefer working with just 0s and 1s right? I would. This would be much easier to work with than a lot of different values.
It’s a herculean task to work with these though as a human. And fortunately, programming languages exist for giving the computer instructions to do in a “language” other than its own.

Answer:
Assuming your talking about a computer virus(because your under the Computers and Technology section)
Also assuming you meant "What is a distinctive characteristic of a virus or virus family."
A computer virus is a software that was created with the intent of damaging a computer. Computer viruses can replicate them selves by modifying other software on the computer. Viruses such as file infectors can override the machine code of another application and inject its own malicious machine code to perform malicious acts. This is especially dangerous for the OS as the virus can override essential files.

Write a method named isNumericPalindrome that accepts an integer parameter named num. If num is a palindrome the method must return true. Otherwise the method must return false. You can assume as a precondition that num has exactly 5 digits (i.e. it is between 10000 and 99999.) For example, 12321 is a palindrome while 12231 isn't because it's the same number if reversed. public boolean isNumericPalindrome(int num)
Answer:
Explanation:
The following code is written in Java. It is a method that reverses the number that is passed as an argument and compares it to its original version. Then it finally returns the results of the comparison as a boolean (either True or False). Two test cases have been created and can be seen in the attached image below.
public static boolean isNumericPalindrome(int num) {
String numString = Integer.toString(num);
String reversed = "";
for (int i = numString.length()-1; i >= 0; i--) {
reversed += numString.charAt(i);
}
return numString.equals(reversed);
}

A. bottom
B. right
C. left
D. center
Answer:
center
Explanation:
that is the focal point
Answer:
D
Explanation:
since it's the main feature of the video it would be best to put it on the center so that all focus is on it because if you put it in the corner or another position it won't be the main feature and definitely not the center of attraction.

Assume X and Y are indepndent. Assume that X has mean 10 and standard deviation 8. Assume Y has mean 12 and standard deviation 6. What is the standard deviation of the variable Z = X + Y. a. 8 b. 6 c. 10 d. 12
Answer:
[tex]\sigma_z = 10[/tex]
Explanation:
Given
[tex]\bar x = 10[/tex]
[tex]\sigma_x = 8[/tex]
[tex]\bar y = 12[/tex]
[tex]\sigma_y = 6[/tex]
[tex]z = x + y[/tex]
Required
[tex]\sigma_z[/tex]
This is calculated as:
[tex]\sigma_z = \sqrt{Var(x) + Var(y)}[/tex]
Calculate [tex]Var(x)[/tex]
We have:
[tex]Var(x) = \sigma_x^2[/tex]
[tex]Var(x) = 8^2[/tex]
[tex]Var(x) = 64[/tex]
Calculate [tex]Var(y)[/tex]
We have:
[tex]Var(y) = \sigma_y^2[/tex]
[tex]Var(y) = 6^2[/tex]
[tex]Var(y) = 36[/tex]
So, we have:
[tex]\sigma_z = \sqrt{Var(x) + Var(y)}[/tex]
[tex]\sigma_z = \sqrt{64 + 36}[/tex]
[tex]\sigma_z = \sqrt{100}[/tex]
[tex]\sigma_z = 10[/tex]

What should you do if your engine stalls while you are driving?
A: Hold your steering wheel tightly(power steering is difficult)
B: Shift your transmission to neutral
C: Try to re-start; if unable, stop off road, using four-way flashers
D: All of the above
Answer:
D
Explanation:
All of the above should you do if your engine stalls while you are driving. Thus option D is correct.
What is driving?Driving, which includes operating and moving a vehicle in a controlled manner, includes using a car, scooter, truck, vehicle, or scooter. Drivers must abide by the local highway and traffic rules in order to be allowed to drive on city roads, which is contingent upon a number of requirements being completed.
In most situations, you'll lose auto steering whenever the engine shuts off, making it challenging to spin the wheel, as well as power brakes will shortly follow.
Although it takes significantly more pressure, you could still steer but instead, stop. Put the gearshift in neutral. If you can't restart, stop off the road and use your 4 blinkers. Therefore, option D is the correct option.

You've just deployed a new Cisco router that connects several network segments in your organization. The router is physically located in a server room that requires an ID card to gain access. You've backed up the router configuration to a remote location in an encrypted file. You access the router configuration interface from your notebook computer by connecting it to the console port on the router. You've configured the management interface with a username of admin and a password of password. What should you do to increase the security of this device
Answer:
Change the default administrative user name and password.Use an SSH client to access the router configuration.Explanation:
Remember, we are told the default username and password were simply, "admin" and "password". From a security perspective, both the password and username are weak choices. Hence, to increase the security of the notebook computer where the router configuration management interface is found, it is best you change the password.
Next, by using a Secure Shell Protocol (SSH) client to access the router configuration, the security is enhanced considering the fact the new Cisco router would connect several network segments in the organization.

Suppose you are given a sequence that is described by a formula, starting at index n=0. If you need to change the starting index to n=1, then you just need to replace n in the formula by n+...?
Answer:
[tex]n+1[/tex]
Explanation:
Given
[tex]n = 0[/tex] --- starting index
Required
Change the starting index to [tex]n = 1[/tex]
We have:
