Study Notes

Peer-to-Peer Networks

Peer-to-peer networks allow one computer to act as both client and server.
Common in small businesses and homes.
Easy to set up and less complex than other network types.
Lower cost, as dedicated servers may not be needed.
Suitable for simple tasks like file transfer and printer sharing.
Disadvantages: no centralized administration, less secure, not scalable, and potential for slower performance due to all devices acting as both client and server.

End Devices

End devices are the source or destination of network messages.
Each end device has a unique address used for communication.
Examples include PCs, IP phones, and servers.
Data flows from a source end device through a network and reaches a destination end device.

Intermediary Devices

Intermediary devices connect end devices to the network.
They form internetworks by connecting multiple networks.
Examples include routers, switches, and firewalls.
Functions include regenerating and retransmitting signals, maintaining network pathways, error detection, directing data along alternative paths, and classifying and prioritizing messages.
Essential for data transmission and routing across networks.
Some devices act as repeaters simply regenerating and retransmitting signals.

Network Media

Network media are the channels for data transmission across a network.
Common types are copper wires, fiber-optic cables, and wireless transmissions.
Copper wires encode data into electrical impulses.
Fiber-optic cables encode data into light pulses.
Wireless transmissions use electromagnetic waves.
Factors to consider when choosing network media: maximum signal transmission distance, installation environment, data transmission volume and speed, and cost.
