Answer:
<em>The first step is to download the driver file from the Internet using another Computer system, Copy the driver to a flash or CD then run the installation file on the Desktop Computer.</em>
Explanation:
<em>Driver files can be easily gotten from software sites online or from other secure websites, most times you have to pay for these driver files in some sites for secure and authentic download.</em>
<em>it is very necessary that the user takes note of the exact system name, model and system architecture with respect to when downloading the driver file.</em>

hub is central computer.....True...
Option b is correct. When an overridden method is called from within a subclass, it will always refer to the version of that method defined by the subclass.
Subclasses are classes that can be created by adding new functionality to a parent class, such as new object variables or new methods. In terms of automata theory, a subclass expands the state transition table with new rows and states. However, by overriding (changing) existing functionality, the majority of OO programming languages also enable us to derive subclasses from parent classes. When implementing a class, all that is required to be specified is the new or updated functionality thanks to inheritance mechanisms between parent class and subclass.
Lines connected through a circle connect the subclasses HourlyEmployee and SalaryEmployee to the superclass Employee. The circled letter "d" stands for disjointness, which demands that the specification's subclasses be distinct. As a result, an entity can belong to only one of the specification's subclasses. An individual employee can only be paid either hourly wages or a salary; they cannot be paid both. The open sides of the inheritance (arch) symbols face the superclass.

Hi, you haven't provided the programing language in which you need the code, I'll just explain how to do it using Python, and you can apply a similar method for any programming language.
Answer:
def rightMost(num):
lenNum = len(str(num))
rightNum = num%(10**(lenNum-1))
print(rightNum)
return(rightNum)
Explanation:
In this function we receive an integer number, then we find how many digits this number has, and finally, we find the rightmost digits; the main operation is modulo (takes the remainder after a division), what we want is to take all the digits except the first one, for that reason we find the modulo of the number when divided by ten to the power of the length of the number minus one, for example, if the number is 2734 we divided by 10^(4-1), where four is the length of the number, this way we get 2734/1000 and the module of it is 734.
Answer:
yes administrators have to be concerned
Explanation:
It is necessary for countermeasures to be taken against DoS attacks
The types of attacks that can still occur are:
If the network connection get to be overloaded, there could be flash crown of this computer system and fraudulent activities maybe initiated. By flash crowd we mean that the there is a great deal of traffic on the system and this could cause the network connection to be destroyed.
To reduce the impact of this kind of attacks,
1. there should be enough or excess network bandwidth and distributed servers should be replicated if there is a possibility that network could get to be overloaded.
2. restriction is more commonly done on sporting sites. Restriction brings about an increase in implementation cost.
3. The impact of this type of attack can be reduced by stopping unwanted traffic throught the implementation of filters
4. Use strong antivirus on computer sytems that are used to connect to the internet
