Answer:
The page field is 8-bit wide, then the page size is 256 bytes.
Using the subdivision above, the first level page table points to 1024 2nd level page tables, each pointing to 256 3rd page tables, each containing 64 pages. The program's address space consists of 1024 pages, thus we need we need 16 third-level page tables. Therefore we need 16 entries in a 2nd level page table, and one entry in the first level page table. Therefore the size is: 1024 entries for the first table, 256 entries for the 2nd level page table, and 16 3rd level page table containing 64 entries each. Assuming 2 bytes per entry, the space required is 1024 * 2 + 256 * 2 (one second-level paget table) + 16 * 64 * 2 (16 third-level page tables) = 4608 bytes.
Answer:
Our brain as a central information processor vs. computer having a central processing unit
Our brain takes sensory input → processing/ sense making → in order to produce behavior as output. Computers work similarly: information input → processing → output task
Computers requires both hardware and software to function. Our body is essentially hardware, what we learn from formal education and informal life experiences are software.

Awesome question! I love networking. When you enter a URL into your browser, your computer sends the request to your ISP or internet service provider. Your ISP has a HUGE database that coordinates the IP address to the domain name. This database is called a DNS, or Domain Name Service. So when you submit www.google.com to your ISP, they return look in the DNS and find the IP address. The ISP then returns the IP address to you. Your browser then takes the IP and connects you to the server. The server finally send the index.html file to and your browser and renders it as a web page.
This all happens in the blink of an eye. The internet is truly amazing :D
