What is Latency?

During the first few seconds of your web browsing experience, you may wonder: “What is latency?” This article will explain the different types of latency, how they’re measured, how they impact the user experience, and how you can minimize your latency. If you’re new to the subject, start with these common examples. Listed below are a few everyday situations where latency can be an issue.

Distinct types of latency

There are two primary types of network latency: propagation delay and network latency. The first type of latency refers to the time it takes for the first bit of a message to travel from one point to another. The latter typically refers to the total time it takes for a message to travel from one point to another. Latency can be caused by several factors, including network infrastructure and device-level problems.

A computer’s response time can be affected by the amount of time to process data. Typically, disk latency is more prolonged than network latency. On the other hand, interrupt latency refers to the time it takes a host operating system to respond to a signal. In this case, the host operating system must decide what action to take. Distinct types of latency affect the quality of user experiences, as well.

Measurement of latency

In networking, latency refers to the amount of delay experienced during data transmission. Latency can be small but can be long, depending on the amount of “hops” and distances between systems. Latency can be measured in milliseconds so a high number would mean a slow connection. This is the main distinction between bandwidth and latency. Both have their own advantages and disadvantages, but both are important when determining network performance.

The most basic definition of latency is from the perspective of a passenger. Consider John Doe, for example. He flies from his house in England to his hotel in New York. He needs to wait approximately five hours to get there. This latency is independent of the throughput of the London-New York air link. If ten thousand passengers take the same flight, latency for each is the same. And the longer the distance between the two cities, the lower the latency.

Impact of latency on user experience

Latency refers to the time it takes data to travel from one point to another. This is usually expressed in milliseconds, and it accounts for both the time it takes to get to its destination and the time it takes to get back to the source. Latency is often grouped with other performance measurements, such as bandwidth and throughput. The higher the latency, the worse the user experience. For example, higher latency can slow down webpage load times, interrupt video streams, and make audio streams unusable. Although latency can only affect a small portion of the overall user experience, it can significantly impact performance.

Even though latency may seem trivial compared to bandwidth, it can dramatically impact conversion rates. Amazon, for example, reported that a 100-ms delay cost them 1% of their sales, while Google found that a 500-ms lag in their search results reduced traffic by 20 percent. In addition, a study by Loadstorm found that long latencies also decreased the chances of conversion, resulting in abandoned shopping carts and frustrated users leaving the site.

Ways to reduce latency

The first thing to do to reduce latency is to minimize your internet usage. Latency can impact your computer’s responsiveness, especially when streaming a video or playing a game. Your router, Wi-Fi network, and video or game download speeds are all affected by latency. However, there are several ways to reduce latency without sacrificing performance. Listed below are a few tips to minimize latency on your home network.

– Improve your network’s network performance. Poor network connections typically cause latency, which can lead to various problems. Increasing the speed of your network can help reduce latency, but you have to be aware of possible bottlenecks. Some of the most effective ways to reduce latency include upgrading the hardware and software on your computer, optimizing your network configuration, and removing unnecessary programs. However, these methods may not be effective for all network environments.
