What Is Bandwidth?
The data transfer capacity of a computer network is measured in bits per second (Bps). The phrase can also be used colloquially to describe a person’s ability to perform tasks or think deeply at a given time.
Importance of bandwidth
A web page’s bandwidth is what defines how quickly it loads in a browser. This is likely the most crucial thing to consider when selecting a web hosting platform. It’s crucial to think about how the website and internet connection will affect bandwidth usage.
For a website with a lot of graphics, the bandwidth requirement can be as high as 10 gigabytes or more. A simplified website’s bandwidth utilization will be lower as well. A quicker internet connection, like bigger bandwidth, will allow you to download online pages and movies more quickly.
Measuring bandwidth
While bandwidth used to be measured in bits per second (bps), current network cables have much more capacity, therefore bandwidth is now measured in megabits per second (Mbps) or gigabits per second (GBPS) (Gbps).
Bandwidth connections can be symmetrical, meaning the data capacity is the same in both directions (upload and download), or asymmetrical, meaning the data capacity is not the same in both directions (upload and download) (upload and download).
Upload capacity is usually lower than download capacity in asymmetrical connections, which are common in consumer-grade internet broadband connections. Symmetrical bandwidth is more common in enterprise-grade WAN and DIA lines.
Uses of bandwidth
Following are common some use of bandwidth:
When a network link is overburdened, network engineers have a number of options. The most typical solution is to increase bandwidth. This can be done by expanding the network’s physical throughput capacity or by spreading traffic across multiple lines using port aggregation and load balancing. These methods, however, are not always available.
ISPs or network managers can also use bandwidth throttling to deliberately impede data transmission across the network (up or down). Reduced network congestion, particularly on public access networks, is one of the reasons for bandwidth restrictions.
Throttling is a technique used by ISPs to limit the amount of bandwidth used by a certain user or group of users. A service provider might, for example, give a menu of upload and download bandwidth with tiered pricing. ISPs can also impose bandwidth restrictions to balance network demand across all customers.
Data can be transported more quickly with higher bandwidth (although “bandwidth” is not identical with “internet speed”). More devices can connect at the same time on a network with enhanced bandwidth.
The bandwidth is sometimes used to denote system bandwidth in filter or communication channel systems. When a system is claimed to have a certain bandwidth, it means it can process signals in that frequency range or reduce the bandwidth of a white noise input to that bandwidth.
