Study Notes
The Internet: Structure, Functionality, and Services
- Internet Structure: Each device connected to the internet has a unique identifier known as an IP address (Internet Protocol Address).
- Protocols: These are standardized rules for formatting data to ensure consistent interpretation by any device.
- Network Access Layer: This layer generates data and requests network connections, focusing on applications needing communication.
- Internet Layer: Similar to OSI's Network Layer, it defines protocols for the logical transmission of data throughout the network.
- Transport Layer: Utilizes TCP/IP protocols to acknowledge data receipts and retransmit any lost packets, ensuring correct order and error-free delivery.
- Application Layer: Functions like the OSI transport layer, facilitating end-to-end communication and ensuring data is delivered without errors.
Functionality of the Internet
- Domain Name System (DNS): Converts user-friendly domain names into machine-readable IP addresses.
- Packet Switching: Involves partitioning data into smaller packets that travel through the network independently, being reassembled at the intended destination.
- Internet Protocols: Govern data transmission; TCP/IP is the main protocol supporting reliable data transfers.
- SSL/TLS: Provides secure communication methods over the internet.
- Web Browsing: Involves using web browsers to access information on the World Wide Web, alongside various internet services such as email, streaming, file sharing, and online gaming.
Social Media and Digital Communication
- Integration in Daily Life: Digital technologies connect individuals, allowing for interaction and information sharing.

History of Social Media:
- Early Beginnings (1970s-1990s): Features platforms like Usenet and Bulletin Board Systems (BBS).
- Rise of Social Networking (Late 1990s-Early 2000s): Platforms like SixDegrees.com, Friendster, and MySpace become popular.
- Microblogging and Other Platforms (2000s-Present): Emergence of Twitter, Instagram, LinkedIn, and TikTok, emphasizing brevity and visual content.
- Future of Social Media: Predictions include advancements driven by augmented reality, artificial intelligence, and blockchain technology, potentially leading to innovative platforms.
History of Digital Communication
- Digital Communication: Refers to conveying information using binary code (0s and 1s), fundamentally changing interactions, work processes, and information access.
- Timeline of Evolution: Spanning from early innovations in the 1800s-1900s to the rise of personal computers and the internet during the 1970s-1990s, illustrating the progression of digital communication technologies.
