Study Notes
The Internet and the World Wide Web
- Internet connects billions of computers globally, using TCP/IP protocols.
- The internet uses various technologies, including optical fibers and wireless connections (3G, 4G, Wi-Fi).
- The internet is a network of networks, connecting computers and servers across the world, through routers, switches, and communication channels.
- It was developed by DARPA (Defense Advanced Projects Agency) in the USA, starting in 1969.
How the Internet Works
- The internet operates using clients and servers.
- A client (e.g., laptop) connects to the internet through an Internet Service Provider (ISP).
- Each device is identified by an IP address provided by the ISP.
- Servers store websites and respond to client requests.
- Data travels through optical fibres, converting light signals to electrical signals to reach client devices.
- Data transfer is fast because it is transmitted in binary form (0s and 1s) in packets.
- Domain names (e.g., youtube.com) are easier for users to remember than IP addresses and are translated by DNS servers.
Intranet
- A private network within an organization.
- Designed for internal use (employees, associates).
- Secure platform for sharing information and data, with only authorized users having access.
- Can be used for internal communications, announcements, company documents, and applications.
- More secure than the internet.
- Usually cheaper and easier to implement.
- Intranets use web servers, platforms, and applications.
Extranet
- An extension of a company's intranet.
- Provides controlled access to specific external resources (customers, suppliers, partners).
- Securely shares internal information with external parties (trading partners, customers, etc.)
- Uses internet protocols, especially VPN connections.
- This allows secure access to information.
Advantages and Disadvantages of the Internet/Intranet/Extranet
- Internet:*
- Advantages: Instant messaging, online shopping, online banking, etc.
- Disadvantages: Less secure, need an internet connection, possible security risks.
- Intranet:*
- Advantages: Secure, internal communication, information sharing amongst authorized users.
- Disadvantages: Limited to the organization's internal network, more challenging to share information beyond the organization.
- Extranet:*
- Advantages: Secure access to external parties or customers, sharing information with strategic partners.
- Disadvantages: Security vulnerabilities.
