Study Notes
Internet Standards and Organizations
- The Internet Engineering Task Force (IETF) is responsible for developing Internet standards.
- The ITU-T (International Telecommunications Union - Telecom Group) is based in Geneva, Switzerland.
Network Fundamentals
- The application layer is responsible for HTTP and HTML (Web) standards.
- Pervasive Networking refers to the integration of networking into daily life.
- Broadband communication involves high-speed data transmission over high-bandwidth channels.
Networking Evolution
- The Industrial Revolution introduced computers and networking, changing the way people worked.
- The Technological Revolution collapsed the information lag and brought people together, leading to globalization.
- The Information Age saw the growth of telecommunications and computer networks, enabling rapid transmission of large quantities of information.
Network Models and Architecture
- Wide Area Networks (WANs) connect LANs and BNs across different locations.
- Intranets are private networks for organization use, while Extranets are extended intranets for partners or customers.
- The OSI 7-Layer Model and the Internet's 5-Layer Model are network models developed to solve internetworking problems.
Network Layers and Standards
- The transport layer is responsible for establishing end-to-end connections and translating domain names into numeric addresses according to the Internet's 5-Layer Model.
- The network layer is responsible for making routing decisions according to the 7-Layer Model of OSI.
- Layered network models allow for flexibility and ease of modification in networking.
Standards and Standardization
- Standards provide interoperability and consistency in data communication interfaces.
- Formal standards are developed by organizations, while 'de-facto' standards emerge in the marketplace through widespread adoption.
- A specification in standardization processes involves detailed descriptions of requirements and characteristics.
- The OSI 7-Layer Model is the framework for computer network standards created by the International Standards Organization (ISO).
- Metropolitan Area Networks (MANs) use fiber optics to transmit data across different locations.
