Answer:

A. data-link layer

Explanation:

Data-link layer is the first layer and allows a contiguous sequence of bits to be transmitted through the network.

On top of it is the Network Layer and it handles the task of routing network messages from one computer to another.

Then comes the Transport Layer which is the basic layer at which one network computer communicates with another network computer.

Given two objects represented by the tuples (22, 1, 42, 10) and (20, 0, 36, 8):
Rudik [331]

Answer:

Given,

P = (22, 1, 42, 10)

Q = (20, 0, 36, 8)

a. Formula for Euclidean Distance :

distance = ((p1-q1)^2 + (p2-q2)^2 + ... + (pn-qn)^2)^(1/2)

Now,

distance = ( (22-20)^2 + (1-0)^2 + (42 - 36)^2 + (10-8)^2) ) ^(1/2)

=( (2)^2 + (1)^2 + (6)^2 + (2)^2 ) ) ^(1/2)

=(4+1+36+4)^(1/2)

=45^(1/2)

Distance = 6.7082

b.Manhattan distance :

d = |x1 - x2| + |y1 - y2|

d = |22- 20| + |1 - 0|

d = |2| + |1|

What steps can you take to secure your private information?.
pogonyaev

Answer:

Below:

Explanation:

1. Practice mail security. Use a public mailbox rather than your home mailbox to send bill payments and other mail containing sensitive information. Pick your mail up promptly and ask the post office to hold it while you’re away.

2. Guard your Social Security number. Don’t carry your Social Security card, military ID, Medicare, or other cards that have your Social Security number on them unless you are going somewhere where you will need them. Only provide your Social Security number when there is a legitimate need to do so.

3. Lock and shred. Keep your billing and banking statements and other personal records locked up and shred them when no longer needed.

4. Stop prescreened credit and insurance mailings. Call toll-free 1-888-567-8688 to get off mailing lists for credit and insurance offers. Your Social Security number will be required. This keeps thieves from intercepting and accepting the offers in your name and doesn’t affect your eligibility for credit or insurance.

5. Keep private information to yourself. Never respond to phone calls or emails asking to confirm your Social Security number or account numbers. Don’t leave PIN numbers, passwords or other personal information around for others to see.

6. Be safe online. Use anti-virus and anti-spyware software and a firewall on your computer and keep them updated. When you provide financial or other sensitive information online, the address should change from “http” to “https” or “shttp.” A symbol such as a lock that closes may also indicate that the transmission is secure.

7. Look at your bills and bank statements promptly. If you find any charges or debits that you never made, contact the bank or company immediately.

Hope it helps.......
