Connectivity on a LAN (Edexcel GCSE Computer Science): Flashcards

Local Area Network - connects devices to communicate & share

Wired (cables) and wireless (Wi-Fi signals)

Challenging - each device needs dedicated cable

Simple - only WAPs need cables, devices use SSID & password

Rigid - devices stuck in location, moving requires new cables

Devices move freely within coverage area

Up to 100 metres

Up to 10 Gbps per connection (dedicated pathway)

Up to 3.2 Gbps (shared amongst all devices)

Delay between sending and receiving data

Physically hard to intercept - must access cable directly

Vulnerable - anyone in signal range can intercept transmissions

Combines wired & wireless connections strategically

Assigns internal IP address to each device
