زمن الاستجابة ومعدل النقل
يؤثر زمن الاستجابة في سرعة التفاعل، بينما يؤثر معدل النقل في سرعة نقل البيانات الكبيرة. تحتاج مكالمات الفيديو إلى عرض نطاق كافٍ وزمن استجابة مستقر.
Internet speed test
Measure download, upload, ping and jitter directly in your browser.
Indicative HTTP test via Vercel: server processing may affect ping and upload.

How this internet speed test works
The test first sends tiny requests for ping and jitter, then transfers several blocks in parallel to estimate download and upload. Values update while the test is running.
Download
Download speed determines how fast your device receives data. It affects streaming, downloads and page loads.
Upload
Upload speed matters for video calls, live streaming, cloud backups and file sharing.
Ping / Jitter
Ping measures round-trip latency to the server. Jitter measures how much that latency varies. Competitive gaming and calls benefit from low, stable values.
