Solution
One of the biggest risk with public WiFi is the ability or capacity for hackers to position themselves between you (user) and the point of connection. so instead of communicating directly with the hotpot, at several times you end up sending your information to the hacker.
The hacker also have access or privileges to every information you send out such as credit card information, emails and so on. once the hacker gains access to that information, you run into trouble.
As an end user when making use of public WiFi to ensure to browse with VPN (Virtual private Network) on and turned off sharing options
Nothing online is safe anymore!!!! People and even the government can get hacked easily with today's technology.You can search someone easily on websites like Google or Facebook and even read someone's tweets on Twitter because their account is not private. But what's the point of saying private if they can easily get hacked by someone. There is no safety these days that is why you have to be careful with what you post on the internet in general.
Answer and Explanation:
A TM with doubly infinite tape can simulate an ordinary TM. It marks the left-hand end of the input to detect and prevent the head from moving off of that end. To simulate the doubly infinite tape TM by an ordinary TM, we show how to simulate it with a 2-tape TM, which was already shown to be equivalent in power to an ordinary
TM. The first tape of the 2-tape TM is written with the input string, and the second tape is blank. We cut the tape of the doubly infinite tape TM into two parts, at the starting cell of the input string. The portion with the input string and all the blank spaces to its right appears on the first tape of the 2-tape TM. The portion to the left of the input string appears on the second tape, in reverse order.
Answer:
None
Explanation:
Logical operators:
'and' indicates that the statement is true if both conditions are true.
'or' indicates that the statement is true if one or both conditions are true.
Given that a = 1 and b = 10:
The first statement is false (1×10 <= 1 is false, 1 >= 10 is also false)
The second statement is false (1>10 is false, a does not equal b)
The third statement is false (a does not equal b)
None of these statements are true.
Hope this helps :)
