Network Performance
The measure of how well a network operates, including speed, reliability, and efficiency.
Bandwidth
The amount of data that can be transferred in a given time, typically measured in bits per second (bps).
Number of Devices
More devices connected to a network can reduce performance due to increased data traffic.
Latency
The delay between sending and receiving data, often caused by distance or network congestion.
Error Rate
The frequency of errors in data transmission, which can affect network reliability and speed.
Transmission Media
The physical or wireless medium used to transfer data, such as fibre optic cables or Wi-Fi.
Wired vs Wireless
Wired connections generally offer higher performance and reliability compared to wireless connections.
Interference
External factors like physical obstructions or other signals that can disrupt wireless network performance.
Server Load
The amount of demand placed on a server, which can affect its ability to respond quickly to requests.
Network Congestion
Occurs when too much data is being transmitted, leading to slower speeds and higher latency.
