Peer-to-peer network

A network where each computer acts as both a server and a client, sharing resources directly with each other.

End Device

A device on a network that initiates communication and sends or receives messages, like a computer, smartphone, or printer.

Network Address

Unique identifier assigned to each end device on a network, allowing other devices to locate and communicate with it.

Client-server network

A network where a central device, like a server, manages resources and provides services to connected devices.

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.
