<em>The answer is : He must consult with a lawyer.

<em>Hacking is considered illegal and in other countries, it is punishable by law. Hacking is gaining unauthorized access to a network. Even when someone is giving you permission to do it, it is still wrong and illegal. Therefore, you must know of your rights and make all the party involved to signed an agreement to save yourself.</em>

John can find the amount of Random Access Memory (RAM) memory installed on his computer with the Windows 7 under the category “<u>System and Security</u>” in the Control Panel.
To know the total amount of installed RAM through Control Panel in the computer with Windows 7, John should follow the steps as:
- Click the category named “System and Security”
- Now under “System”, click “View amount of RAM and processor speed”
- “Device Specifications” section displays the amount of installed RAM in John’s computer
Thus, above are the steps by which John’s can find the amount of installed RAM in his Windows 7 computer’s Control Panel.
What is Random Access Memory (RAM)?
RAM is the temporary memory in computers that stores the data currently being used by the processor.

Answer:
All the ports in a hub are in the same collision domain and a hub sends frames from one host to all other hosts in the network. This makes it prone to collision and poor network throughput. Just like a network switch, it uses the CSMA/CD protocol to detect collision in its network.
A network switch reduces its collision domain to just a port and sends frames from one host to another using its mac table as a route. This makes the network very efficient with high throughput. It also uses the CSMA/CD protocol to detect collision
Explanation:
Switches and hubs are used in networking to connect computer devices in a network. A hub is an obsolete device networking that broadcast a frame to all other ports or host in the network except for the send host port. This increases the rate of collision as all the ports in a hub share the same collision domain. A switch is an efficient frame switching device in a network, which uses its MAC table to decide and find a destination host.
CSMA/CD is a collision detection protocol used in a network to detect and prevent a collision. With this protocol, a host is able to listen, wait, send and resend frames to prevent a collision.
