Network Component
What you need to set up a network?
- Hosts/ End Nodes
- Refers to the data source and the data destination. For examples:
- Personal computers
- Terminals
- Workstations
- Automatics Teller Machine
- Transmission Media
Network Electronic Device
- Responsible to control data from source to destination.
- Provide interface between different media transmitter or for different protocol.
- To connect multiple network together or to connect computer or network to the inetrnet.
- Examples of Network Electronic Device
- Bridges
- Routers
- Multiplexers
- Switches
- Hubs
- Gateways
- Front End Processors
Applications/ Software
- The applications at the end nodes ( is a peripheral unit in a network, or a primary designated unit within that network. IT professionals and others use the term "end node" to specify a certain hardware component of a network that has its own role and properties within that network system) normally involves technique and protocols.
- The protocols determines the rules and procedure to send data, terminate data, interpret data, present data and control mistakes.
- Software in the network functions to ensure data is delivered at respective destination.
