Study Notes
Network Fundamentals
- The network layer is responsible for making routing decisions.
- The transport layer initiates, maintains, and terminates logical sessions between sender and receiver.
Data Transmission
- The physical layer defines how individual bits are formatted to be transmitted through the network.
Data Presentation
- The presentation layer formats data for presentation to the user and provides data interfaces, data compression, and translation between different data formats.
Industrial Revolution
- The Second Industrial Revolution brought significant changes to the way industries operated.
Networking Basics
- Understanding networking involves three parts: devices, media, and network protocols.
Local Area Network (LAN)
- A LAN consists of three components: devices, media, and network protocols.
Network Evolution
- The time taken for information transmission decreased significantly from pre-1850s to 2007.
Network Types
- A Wide Area Network (WAN) connects LANs and Basic Networks (BNs) across different locations.
- A Metropolitan Area Network (MAN) shares a high-speed backbone linking together organizational LANs at various locations.
Network Access
- The main difference between an intranet and an extranet is that an intranet is accessible only to an organization's members, while an extranet is accessible to partners and suppliers.
Network Models
- The OSI (Open Systems Interconnection) model is a 7-layered network model created by the International Standards Organization (ISO).
Networking Approach
- Breaking down networking into smaller components helps to understand and manage complex networks more efficiently.
Network Terminology
- MAN stands for Metropolitan Area Network in the context of network types based on scale.
