Types of Broadband Internet Connections

Types of Broadband Internet Connections

• DSL (Digital Subscriber Line) utilizes existing telephone lines for internet access, widely available but speed varies depending on distance from the service provider.
  • Advantages: Generally more widely available and often cheaper compared to other broadband types. Allows simultaneous use of phone line and internet.
  • Disadvantages: Speed can vary based on distance from the service provider's central office. Farther away you are, slower the speed.
• Cable Internet is provided through the cable television network using coaxial cables, generally offers higher speeds than DSL and is also widely available.
  • Advantages: Typically faster than DSL and can handle high-speed data for streaming and downloads.
  • Disadvantages: Connection speed can be influenced by the number of users in an area as bandwidth is shared among multiple subscribers.
• **Fiber-optic Internet ** offers the highest speeds and reliability by using fibers that transmit data via light, excellent for high-speed downloads and uploads but isn't as widely available as DSL or cable.
  • Advantages: Offers very high speeds for both uploads and downloads and is less susceptible to interference than cable or DSL.
  • Disadvantages: Availability is still limited in comparison to DSL and cable, often restricted to urban and suburban areas.
• Satellite Internet is useful in rural areas where cable and DSL aren’t available, uses a satellite dish to provide internet but can be affected by weather conditions and typically has higher latency.
  • Advantages: Available almost anywhere on the planet, making it ideal for rural or remote areas.
  • Disadvantages: Typically has higher latency and lower speeds compared to terrestrial broadband. Weather conditions can also affect connectivity.
• Fixed Wireless Internet also aimed at rural areas, uses radio signals from a nearby base station, doesn’t require cable or phone line installations but can be influenced by physical obstructions and weather.
  • Advantages: Does not require cable or phone line installations, making it useful in rural areas and places where other broadband types aren’t available.
  • Disadvantages: The quality of the connection can be affected by physical obstructions like buildings and trees, and sometimes by weather conditions.

Types of Internet Access Providers

• Internet Service Providers (ISP) provide internet access via various technologies like DSL, fiber, or cable, manage internet traffic and offer connection to residential and business customers.
  • Examples:
    • PLDT: Offers fiber, DSL, and wireless broadband services.
    • Converge ICT: Provides fiber internet across many cities and provinces.

Web Browser and Web Address

• Web Browser is software used to access and navigate the World Wide Web, allows users to view websites, download files, play videos, and interact with online content.
  • Examples: Google Chrome, Mozilla Firefox, Microsoft Edge, and Safari.
• Web Address is another term for a URL (Uniform Resource Locator), the string of characters you type into a web browser's address bar to access a specific website or resource on the internet.
  • It contains information about the location of a resource, including the website's domain name and sometimes specific pages, files, or data.

Components of a Web Address

• Protocol: Specifies how data is transferred between the browser and the web server (e.g., "http://" or "https://" for secure connections).
• Domain Name: Identifies the website (e.g., www.example.com).
• Path: Specifies a particular page or file on the website (e.g., "/about-us").
• Query String: Provides additional data to the server, often for searches or dynamic content (e.g., "?search=term").
• Port Number (optional): Specifies the port used to access the resource (e.g., ":80" for HTTP or ":443" for HTTPS).
• Fragment (optional): Refers to a specific section of a page (e.g., "#section1").

Search Engine

• A search engine is a software system designed to search for information on the internet. It helps users find relevant websites, images, videos, news, and other types of content based on the keywords or phrases they enter into the search bar.
  • Popular Examples: Google (most widely used), Bing, Yahoo, DuckDuckGo (focused on privacy).

How a Search Engine Works

• Crawling: The search engine uses bots (spiders or crawlers) to scan the web and gather information about web pages.
• Indexing: The information collected by the bots is stored in the search engine’s index (a vast database of web content).
• Ranking: When you search for something, the search engine’s algorithm sorts through the indexed pages and ranks them based on their relevance to your search.
• Results Display: The most relevant results appear at the top of the list on the search engine results page (SERP) with a link, a short description, and sometimes additional information.

How to use a search engine

1. Open a Web Browser: Launch a web browser like Google Chrome, Mozilla Firefox, Microsoft Edge, or Safari.
2. Go to a Search Engine: In the address bar, type the URL of a search engine, such as www.google.com, www.bing.com, or www.yahoo.com.
3. Enter Your Search Query: In the search box, type the keywords or phrases that describe the information you're looking for. Be specific to get better results.
4. Press Enter or Click the Search Button: After typing your query, press the "Enter" key or click the search button (usually a magnifying glass icon).
5. Review the Search Results: A list of web pages that match your search will appear. These results typically include the title of the page, a brief description, and the URL.
6. Click on a Result: Click on the link to a web page that looks most relevant to your search. It will open the page in your browser.
7. Refine Your Search if Necessary: If you don't find what you're looking for, try refining your search by changing or adding keywords.
