Hi, i have a few questions that i need clarification on.
1- What are some pros and cons of cloud computing.
2-How are URLS converted into IP's?
3- How do you know if a network is peer-to-peer or client server in a home apart from there being no physical server?
Component 2-
How would you draw more advanced logic gates like A AND (B OR C)
How do you calculate the amount of bits of a bitmap image?
How does a character set represent a strong in a variable?
Thank you

1- pros : can be accessed from any time, anywhere from any connected device. Easy to add more devices. Little hardware required
cons: must have access to the internet. Vulnerable to attacks
2- The URL is typed into the search engine. The DNS holds the translations of all the URLs into IP addresses. The IP address for the URL typed in is located in the DNS and the website is redirected
3- Files are not stored in a central device. Copies of files have to be made to send them to other devices. All computers have access to files in the network
4- draw the logic gate for B OR C first. Then draw the AND logic gate with input values of A and the result of (B OR C)
5+6- unsure about these ones sorry
cons: must have access to the internet. Vulnerable to attacks

above the B OR C gate write A. then draw a line from the B OR C gate into the AND gate. the other input into the AND gate is A
