Networking Devices and Models Flashcards

Vocabulary-style flashcards covering networking hardware, network types, and server models based on the Chapter 2 lecture notes.

networking devices

A collection of computers and devices connected together for communication purposes.

Benefits of Networking

Resources such as files and data can be shared, and data can be backed up centrally.

Drawbacks of Networking

Cables and servers can be expensive, managing large networks is complex, and malware or hacking can affect the entire network.

Switches

Devices that connect other devices to form a LAN and direct incoming data packets to a specific destination address only.

hubs

Devices that connect other devices to form a LAN and direct incoming data packets to all devices on the network.

Lan

Consists of computers and devices connected to switches or hubs; it is owned by a private network, more secure, and has a higher data transfer rate.

Wan

Owned by a public network, it has a lower data transfer rate and uses transmission by fibre optic cable or satellite.

Client Server model

A network model using separated dedicated servers where the server dictates which user can access which files; suitable for a large number of clients needing good security.

Client Server application

Common examples include printers and Email Servers.

Peer to peer model

A decentralized network with no central server where each node can share its files with all other nodes and there is no requirement for user authentication.

Peer to peer application

Commonly used for communication tools and small networks of users with no need for robust security.
