What is Bandwidth?

Bandwidth refers to the maximum amount of data that can be transmitted over a network connection in a specific amount of time. It is essentially the data-carrying capacity of your internet connection.

Think of bandwidth like the width of a highway. A wider highway with more lanes can handle more cars (data) at the same time, allowing traffic to move smoothly. A narrow, single-lane road can become congested quickly. Similarly, a connection with higher bandwidth can handle more simultaneous activities—like voice calls, video conferences, and file downloads—without a drop in performance.

In digital networks, which are used for all modern IP communications, bandwidth is measured in bits per second (bps). You will commonly see it expressed in larger units:

• Kbps (Kilobits per second): Thousands of bits per second.
• Mbps (Megabits per second): Millions of bits per second.
• Gbps (Gigabits per second): Billions of bits per second.

Having sufficient bandwidth is critical for ensuring high-quality VoIP calls, clear video meetings, and fast data transfers. In contrast, insufficient bandwidth can lead to issues like choppy audio, lagging video, and slow connection speeds.
