網絡術語詞彙表 Network Glossary
測速結果入面嘅 Mbps、Ping、Latency 係咩意思？以下詞彙表用中英對照解釋常見嘅網絡術語，幫你更好咁了解你嘅網速測試結果。
Mbps (Megabits per second)
每秒兆位元
網速嘅常用單位，1 Mbps = 每秒傳輸 1,000,000 bits 嘅數據。注意 Mbps（小寫 b）同 MBps（大寫 B）唔同，1 MBps = 8 Mbps。
Common unit for internet speed. 1 Mbps = 1,000,000 bits per second. Note: Mbps (lowercase b) differs from MBps (uppercase B); 1 MBps = 8 Mbps.
Download Speed
下載速度
你嘅裝置從互聯網接收數據嘅速度。影響網頁載入、串流影片、下載檔案等日常使用。
The rate at which your device receives data from the internet. Affects web browsing, video streaming, and file downloads.
Upload Speed
上載速度
你嘅裝置向互聯網發送數據嘅速度。影響視像通話、上傳檔案、直播等。上載速度通常比下載速度慢。
The rate at which your device sends data to the internet. Affects video calls, file uploads, and live streaming. Usually slower than download speed.
Ping / Latency
延遲 / 反應時間
數據從你嘅裝置去到伺服器再返嚟嘅時間，以毫秒（ms）為單位。Ping 值越低越好，對於網上遊戲同視像通話尤其重要。一般低於 20ms 為優秀，20-50ms 良好，50ms 以上可能有明顯延遲。
The time it takes for data to travel from your device to a server and back, measured in milliseconds (ms). Lower is better, especially important for online gaming and video calls. Under 20ms is excellent, 20-50ms is good, above 50ms may cause noticeable lag.
Jitter
抖動
Ping 值嘅波動幅度。Jitter 越高，網絡越唔穩定。高 jitter 會導致視像通話斷斷續續、網上遊戲卡頓。理想嘅 jitter 應低於 30ms。
The variation in ping values over time. Higher jitter means less stable connections. Can cause choppy video calls and gaming lag. Ideally below 30ms.
Bandwidth
頻寬
你嘅網絡連線喺指定時間內可以傳輸嘅最大數據量。好似水喉嘅闊度 — 越闊，同一時間可以通過嘅水（數據）就越多。
The maximum data transfer capacity of your connection. Like a water pipe — wider pipes allow more water (data) to flow at once.
ISP (Internet Service Provider)
互聯網服務供應商
提供互聯網接入服務嘅公司。香港主要 ISP 包括 HKBN 香港寬頻、HGC 環電、Netvigator 網上行（PCCW）、SmarTone 等。詳見 香港 ISP 比較。
Companies that provide internet access. Major Hong Kong ISPs include HKBN, HGC, Netvigator (PCCW), SmarTone, etc. See our <a href="/hk-isp/">HK ISP Comparison</a>.
Fiber / FTTH (Fiber to the Home)
光纖 / 光纖入屋
用光纖直接連接到你屋企嘅寬頻技術。比傳統銅線（DSL）快好多，可提供 1Gbps 甚至 10Gbps 嘅速度。香港光纖覆蓋率超過 95%。
Broadband technology using fiber optic cables directly to your home. Much faster than traditional copper (DSL), offering speeds up to 1Gbps or even 10Gbps. Hong Kong has over 95% fiber coverage.
5G
第五代流動通訊
最新一代流動網絡技術，理論下載速度可達 1-10Gbps，延遲低至 1ms。香港主要電訊商都已經提供 5G 服務。
Latest generation mobile network technology with theoretical download speeds of 1-10Gbps and latency as low as 1ms. All major HK telcos now offer 5G service.
Wi-Fi 6 / Wi-Fi 6E
Wi-Fi 6 / Wi-Fi 6E
最新嘅 WiFi 標準（802.11ax），支援更快速度、更多同時連接裝置、同更低延遲。Wi-Fi 6E 額外支援 6GHz 頻段，進一步減少干擾。
Latest WiFi standard (802.11ax) supporting faster speeds, more simultaneous devices, and lower latency. Wi-Fi 6E adds 6GHz band support for less interference.
DNS (Domain Name System)
域名系統
將網址（如 speedtesthk.com）轉換成 IP 地址嘅系統。使用快嘅 DNS（如 Cloudflare 1.1.1.1 或 Google 8.8.8.8）可以輕微改善網頁載入速度。
System that translates domain names (like speedtesthk.com) to IP addresses. Using fast DNS servers (like Cloudflare 1.1.1.1 or Google 8.8.8.8) can slightly improve page load times.
Packet Loss
丟包率
數據封包喺傳輸過程中遺失嘅比例。即使少量丟包（1-2%）都會明顯影響網絡質素，導致影片卡頓、遊戲延遲等問題。理想嘅丟包率係 0%。
The percentage of data packets lost during transmission. Even small packet loss (1-2%) can noticeably affect quality, causing video stutter and gaming lag. Ideal packet loss is 0%.
