Week 2: Introduction to Web Design

Overview of Topics

  • Fundamentals of Internet Connectivity

    • Role of Internet Service Providers (ISPs)

    • IP Addresses and Domain Names

    • Function of Web Browsers

Objectives

  • Explain the concepts of internet connectivity.

  • Describe how users connect to the internet and the role of ISPs.

  • Introduce building blocks of web pages, including HTML, CSS, and JavaScript.

Internet Connectivity

  • User Connection

    • Users connect to the internet through an ISP (e.g. PLDT, Globe).

    • Examples of ISP types: WiFi at home vs. mobile data.

  • ISP Definition

    • ISP is a company that provides internet access to homes and businesses

    • They maintain infrastructure to connect users to the internet.

Internet Access Types

  • ISPs offer different plans based on speed (e.g., 25 Mbps, 50 Mbps, 100 Mbps).

  • Differences between residential and business internet plans.

Network Types

  • Introduction to network topologies: 8 different types of network topologies to be covered.

IP Addresses

  • Definition: Unique set of numbers identifying every device on the internet, enabling communication between devices.

  • Types of IP Addresses:

    • IPv4: Older version, consists of 32 bits (4 bytes) and is running out of available addresses.

    • IPv6: Newer system with a much larger address space, uses hexadecimal format.

  • Dynamic vs Static IP Addresses:

    • Dynamic IP Address: Changes periodically each time a device connects.

    • Static IP Address: Remains constant, typically used for specific needs like hosting servers.

Network Topologies

  • Star Topology: Devices connected to a central hub or switch.

  • Bus Topology: All devices share a single communication line; newer networks rarely use this.

  • Ring Topology: Each device connected in a circular format.

  • Mesh Topology: Devices are interconnected directly, enhancing reliability.

  • Hierarchical Topology: Multi-level hierarchy connecting various devices through parent-child relationships.

  • Hybrid Topology: Combination of different topologies to suit specific needs.

  • Point-to-Point Topology: Direct connection between two devices, often used for file sharing.

Additional Key Points

  • IP Address Formatting:

    • IPv4 addresses are represented with decimal numbers separated by dots.

    • IPv6 addresses are represented in hexadecimal format, separated by colons.

  • Packet Loss: Understanding how data packets travel over networks and how routing is done using IP addresses.

  • Activity and Further Learning: Activities related to the topics will be shared, ensuring reinforcement of the lessons learned.

Conclusion

  • Aim to understand the fundamental aspects of web design, the role of ISPs, IP addressing, and network topologies.

  • Questions were taken from the class regarding these topics.
