Answer:
Accessibility in the sense considered here refers to the design of products, devices, services, vehicles, or environments so as to be usable by people with disabilities. The concept of accessible design and practice of accessible development ensures both "direct access" (i.e. unassisted) and "indirect access" meaning compatibility with a person's assistive technology (for example, computer screen readers).
Accessibility can be viewed as the "ability to access" and benefit from some system or entity. The concept focuses on enabling access for people with disabilities, or enabling access through the use of assistive technology; however, research and development in accessibility brings benefits to everyone.
Accessibility is not to be confused with usability, which is the extent to which a product (such as a device, service, or environment) can be used by specified users to achieve specified goals with effectiveness, efficiency, convenience satisfaction in a specified context of use.
Accessibility is strongly related to universal design which is the process of creating products that are usable by people with the widest possible range of abilities, operating within the widest possible range of situations. This is about making things accessible to all people (whether they have a disability or not).Explanation:
Hi!
When someone repeatedly compares passwords to lists of common words, this is known as the dictionary attack.
We call it this because they are <em>literally </em>using a dictionary to attack you!
Hopefully, this helps! =)
Answer:
Explanation:
The following code is written in Python. It creates a variable that detects the current time. Then it loops through a range of numbers and chooses the last random number after 2 seconds. Finally, it prints that number to the screen. This function can be called countless times depending on the number of state lottery numbers needed.
import random
import time
start_time = time.time()
while time.time() - start_time < 2:
lottery_number = random.randint(0, 48)
print(lottery_number)
Answer:
D.
Explanation:
In combinational circuits, the current output values are always the same for the same set of input values, regardless the previous values.
We say that combinational circuits have no memory, or that the circuit has no feedback from the outputs.
For sequential circuits, on the contrary, the current output values are not based in the current input values only, but on the previous output values as well.
So, the fact of having a defined set of input values at a given moment, doesn't guarantee which the output values will be.
We say that sequential circuits have memory, or that they have feedback from the outputs.
Examples of these type of circuits are R-S, J-K, D or T flip-flops.
Answer:
Follwing is the python code:-
word=str(input("Enter the string\n"))
new=word[0:3] #expression for first three characters of the string.
print(new)
Output:-
Enter the string
chandelier
cha
Explanation:
The expression word[0:3] is for extracting first three characters form the string.
word[0:3] = It extracts characters from index 0 to index 2 it does not include 3.3 is excluded.
