Advanced Concepts in Internet and Web Applications

The chapter Internet and Web Applications becomes more scoring when students understand deeper concepts and real-life applications. These advanced topics are frequently used in exams to test analytical skills.

1. Client-Server Architecture

In Internet and Web Applications, communication happens through a client-server model:

  • Client: User device (computer, mobile)
  • Server: Stores and provides data

When a user requests a webpage, the client sends a request to the server, and the server responds with the required data.

2. IP Address and Domain Name

Every device connected to the internet has a unique IP address.

  • IP Address: Numeric identifier (e.g., 192.168.1.1)
  • Domain Name: Human-readable name (e.g., google.com)

DNS (Domain Name System) converts domain names into IP addresses.

3. Cloud Computing

Cloud computing is an important concept in Internet and Web Applications. It allows users to store and access data over the internet instead of local storage.

Types of cloud services:

  • IaaS (Infrastructure as a Service)
  • PaaS (Platform as a Service)
  • SaaS (Software as a Service)

Examples: Google Drive, Dropbox

4. E-Commerce and Online Services

The chapter Internet and Web Applications includes real-life applications such as:

  • Online shopping
  • Digital payments
  • Ticket booking
  • Online education

These services depend heavily on web applications.

5. Cyber Threats and Protection

Common cyber threats:

  • Phishing
  • Malware
  • Viruses
  • Hacking
