Complete Question:
In which type of hacking does the user block access from legitimate users without actually accessing the attacked system?
Group of answer choices
a. Denial of service
b. Web attack
c. Session hijacking
d. None of the above
Answer:
a. Denial of service
Explanation:
Denial of service (DOS) is a type of hacking in which the user (hacker) blocks access from legitimate users without actually accessing the attacked system.
It is a type of cyber attack in which the user (an attacker or hacker) makes a system or network inaccessible to the legitimate end users temporarily or indefinitely by flooding their system with unsolicited traffic and invalid authentication requests.
A denial of service is synonymous to a shop having a single entry point being crowded by a group of people seeking into entry into the shop, thereby preventing the legitimate customers (users) from exercising their franchise.
Under a DOS attack, the system or network gets stuck while trying to locate the invalid return address that sent the authentication requests, thus disrupting and closing the connection. Some examples of a denial of service attack are ping of death, smurf attack, email bomb, ping flood, etc.

The class definition for Javascript:
var Class = {
arguments of the class object are initialized here;
}
This class definition for Python:
class "class_name"( object ):
def __init__(self, arguments are passed are and initialized after the closing parenthesis)
Explanation:
Object-oriented programming languages are vital tools in creating data structures that are meant to be changeable, unindexed but directly accessible knowing the key value, and has unique membership.
This clearly is an adoption of the set data structure rule in creating a data structure blueprint that can be instantiated anytime in the code.

Does the cloud solution offer equal or greater data security capabilities than those pro-vided by your organization’s data center?
Answer:I think greater. Answer my question that I posted plz
Explanation:
Which one is the result of the output given by a computer
I
Explanation:
Instruction , data and information all of these.the base on which the number n=(34)? is written if it has a value of n= (22)10
If I'm understanding the question correctly, you are looking for an integer b (b ≠ 0, b ≠ 1) such that
[tex]34_b = 22_{10}[/tex]
In other words, you're solving for b such that
3×b ¹ + 4×b ⁰ = 22
or
3b + 4 = 22
Solving this is trivial:
3b + 4 = 22
3b = 18
b = 6
So we have
34₆ = 22₁₀

Consider two different processors P1 and P2 executing the same instruction set. P1 has a 3 GHz clock rate and a CPI of 1.5. P2 has a 3 GHz clock rate and a CPI of 1.0. Which processor has the highest performance expressed in instructions per second
Answer:
Processor P2 has the highest performance expressed in instructions per second.
Explanation:
Given:
Processors:
P1
P2
Clock rate of P1 = 3 GHz
Clock rate of P2 = 3 GHz
Cycles per instruction = CPI of P1 = 1.5
Cycles per instruction = CPI of P2 = 1.0
To find:
which processor has the highest performance in instructions per second (IPS)
Solution:
Compute CPU time:
CPU time = (Number of instructions * cycles per instruction) / clock rate
CPU time = (I * CPI) / R
We are given the CPI and clock rate. So
CPU time = (I * CPI) / R
I / CPU time = R/CPI
Since
Instructions per second = Number of instructions (I) / execution time
IPS = I / CPU time
So
Instructions Per Second = clock rate / cycles per instruction
IPS = R/CPI
Putting the values in above formula:
Instructions Per Second for P1 = IPS (P1)
= clock rate P1 / CPI (P1)
= 3 GHz / 1.5
IPS (P1) = 2
As 1 GHz = 10⁹ Hz
IPS (P1) = 2x10⁹
Instructions Per Second for P2 = IPS (P2)
= clock rate P2 / CPI (P2)
= 3 / 1.0
IPS (P2) = 3
As 1 GHz = 10⁹ Hz
IPS (P2) = 3x10⁹
Hence processor P2 has the highest performance expressed in instructions per second i.e. 3x10⁹
The first electric, general-purpose computer, ENIAC, was programmed by calculating algorithms on paper entering code directly into the computer flipping switches by hand using MS-DOS as the operating system
Complete Question:
The first electric, general-purpose computer, ENIAC, was programmed by?
Group of answer choices.
A. Calculating algorithms on paper.
B. Entering code directly into the computer.
C. Flipping switches by hand.
D. Using MS-DOS as the operating system.
Answer:
C. Flipping switches by hand.
Explanation:
The first electric, general-purpose computer, ENIAC, was programmed by flipping switches by hand.
ENIAC is an acronym for Electronic Numerical Integrator and Computer, it was developed in 1945 by John Mauchly and J. Presber Eckert. ENIAC was used for solving numerical problems or calculation-related tasks by the process of reprogramming.
In order to give the ENIAC a series of machine instructions to follow in the execution of a task, the programmers had to undergo the cumbersome procedure of connecting, removing, reconnecting cables and flipping switches by hand because data couldn't be stored in memory.
Which type of user profile is stored in the C:\Users folder and is automatically created when a user logs on to the computer for the first time?
Answer:
a. Local user profile.
Explanation:
Local user profile is a type of user profile which is stored in the C:\Users folder and is automatically created when a user logs on to the computer for the first time and it is being stored on the local hard disk of the computer.
Generally, in Microsoft windows any change made to the local user profile is peculiar to the user and the host computer on which the change is made.
Hence, local user profiles avails several users the opportunity of sharing a single computer with their respective user settings and data.

Req. 2 The system shall primarily an end-user system. Users shall use the system within the constraints of the permissions assigned by the administrator to identify, locate, order and receive documents. Req. 3 Users shall communicate with the system mainly via the html interface. Req. 4 User shall provide input to the system via the html interface. Req. 5 The system shall give output to the user via the html interface, email and print. The print output shall mainly be documents.

Redundancy
Req. 1 and Req. 3 are seemed to say the same thing. We need to remove the first sentence in Req. 1
Conflict and understandability
Req. 1 states that access is through web browser while Req. 4 states that access is via html. We have to re-write the Req. 3 to make it clear that users do not actually have to write directly html to communicate with the system.
Completeness
Req. 5 states that print out will “mainly” be documents. What else might be printed? What other inputs will be produced?
Either remove mainly or clarify other print out.

A good machine should have the mechanical advantage of......?
Answer:
The ideal mechanical advantage (IMA) of an inclined plane is the length of the incline divided by the vertical rise, the so-called run-to-rise ratio. The mechanical advantage increases as the slope of the incline decreases, but then the load will have to be moved a greater distance.
Explanation:
This method adds newValue to the list at the specified index. If the index is invalid for the list, throw an IndexOutOfBoundsException. Note that the last valid index is the size of the list; this would mean adding to the back of the list. Call any existing methods of LinkedList and LLNode as needed.
Answer:
i dont know
Explanation:
A user in an apartment building on a wireless network is no longer able to print to the network printer. The user has been able to print to the printer in the past and nothing on the network has changed. A technician notices that the user has a different IP address scheme than what was originally setup and is able to browse the Internet using that IP address scheme. What should he do?
Answer:
The technician should either provide a route from the user's IP scheme to the printer or change the user's IP scheme to be within the same scheme as the printer.
Explanation:
The most likely reason the user is unable to print to the printer is that the user's computer cannot path the current address to the address of the printer. Without the printer being on the same subnet as the user's computer, the computer has no way of being able to tell where the printer is.
The two solutions to this are to either add a route to the user's computer explicitly telling the user's computer where to trace to find the printer or to change the user's computer to match the IP scheme of the printer.
