Topology refers to the physical or logical arrangement of computers and devices in a network. It defines how devices are connected and how data flows between them.

For a school network, a star topology would be the best choice. In a star topology, all computers are connected to a central device like a switch or hub. This topology offers several advantages for a school environment:

• Easy to install and manage
• If one computer fails, it doesn't affect the rest of the network
• Easy to add new computers without disrupting the network
• Centralized management makes troubleshooting easier
• Provides good performance for typical school activities

Example URL: https://www.example.com:443/path/to/page.html?query=value#section

Different sections of a URL:

• Protocol (https://) - Specifies how data is transferred between the browser and server
• Subdomain (www) - A subdivision of the main domain
• Domain (example.com) - The main address of the website
• Port (:443) - The communication endpoint (optional, defaults to standard ports)
• Path (/path/to/page.html) - The specific location of the resource on the server
• Query (?query=value) - Additional parameters sent to the server
• Fragment (#section) - A specific section within the page

Ranking refers to the process of ordering search results based on their relevance and importance to the user's query.

In search engines, ranking is crucial because:

• It determines which web pages appear first in search results
• It helps users find the most relevant information quickly
• It's based on complex algorithms that consider factors like:
  • Keywords in the content
  • Quality and authority of the website
  • User engagement metrics
  • Freshness of content
  • Mobile-friendliness
• Good ranking drives traffic to websites
• Search engines continuously update their ranking algorithms to improve user experience

BCC (Blind Carbon Copy) is an email field used to send copies of an email to recipients without other recipients knowing who received the BCC copies.

Uses of BCC:

• To protect recipients' privacy when sending to multiple people
• To send a copy to someone without the main recipients knowing
• For mass emails where you don't want to reveal all recipients' addresses

Example: When sending a newsletter to 100 subscribers, you would put all email addresses in the BCC field. This way, no subscriber can see the other subscribers' email addresses, protecting everyone's privacy. The "To" field could contain your own email address or be left blank.
