Study Notes
Network Hardware
- Network cables are transmission media that transfer data between devices
- Category 5 cable with RJ-45 connector is a commonly used network cable
- Routers are connecting devices that transfer data packets between different computer networks
- Routers contain RJ-45 ports for connecting computers and devices using network cables
- Repeaters, hubs, and switches connect network devices together as a single segment
- Repeaters receive signals, regenerate them, and re-transmit to extend transmission distance
- Hubs are multiport repeaters with several input/output ports, broadcasting input to all ports
- Switches receive data, use packet switching to resolve destinations, and forward to specific devices
Network Software
- No notable points mentioned in the text
Reference Models
- OSI Model is a layered networking framework developed by International Standards Organization (ISO)
- OSI Model has seven interconnected layers: physical, data link, network, transport, session, presentation, and application
- TCP/IP Protocol Suite is a suite of protocols for communication structured in four layers: application, transport, internet, and network access
Physical Layer
- Physical layer transmits bits between devices, managing physical and electrical details
- Physical layer defines encoding types, communication modes, network connection types, physical topologies, and media bandwidth
- Functions of physical layer include representing encoding types, communication modes, network connection types, physical topologies, and media bandwidth
