📌 Latency Sources Summary
Latency sources are the different factors or steps that cause a delay between an action and its visible result in a system. These can include the time it takes for data to travel across a network, the time a computer spends processing information, or the wait for a device to respond. Understanding latency sources helps in identifying where delays happen, so improvements can be made to speed up processes.
🙋🏻♂️ Explain Latency Sources Simply
Imagine sending a letter to a friend. The total time before your friend reads it includes the time you write the letter, the postal service delivers it, and your friend opens it. Each step adds some delay, just like different latency sources add up in a computer system.
📅 How Can it be used?
Identifying latency sources helps developers optimise system performance by targeting the components that contribute most to delays.
🗺️ Real World Examples
In online video games, players may experience lag if the game server is far away, the internet connection is slow, or their computer processes graphics slowly. Each of these is a different source of latency affecting the gaming experience.
When making a video call, delays can occur due to the time it takes for audio and video data to be captured, compressed, sent over the internet, decompressed, and displayed on the other person’s device. Each stage contributes to the overall latency.
✅ FAQ
What are the main reasons for delays when using computers or the internet?
Delays can happen for several reasons, such as the time it takes for information to travel between devices, how quickly a computer processes data, or how fast a device responds to a request. Even small steps like loading a webpage or waiting for a video to start can involve many of these sources of latency working together.
How can understanding latency sources help make things faster?
By knowing where delays come from, it becomes easier to spot which step is slowing things down. For example, if a game feels sluggish, it might be due to slow internet, or perhaps the device itself is taking too long to process information. Pinpointing the cause means you can focus on fixing the right issue, making the whole experience smoother.
Does every device or system experience latency in the same way?
No, different devices and systems can have different sources of latency. For instance, a smartphone might be slower because of its hardware, while a desktop computer might be quick but experience delays due to network issues. Each situation is unique, which is why understanding the various sources of latency is so useful.

💡Other Useful Knowledge Cards
Incident Monitor
An Incident Monitor is a system or tool that observes and tracks events or problems as they happen within an organisation's digital or physical environment. It collects information about incidents, such as system outages, security breaches, or operational issues, and alerts relevant people so they can respond quickly. Incident Monitors help organisations minimise downtime and prevent small issues from becoming bigger problems by providing real-time updates and historical records.
Decentralized Identity Systems
Decentralised identity systems let people control their personal information without relying on a single organisation or central authority. Instead, users store and manage their identity details on their own devices or through secure, distributed networks. These systems use technologies like blockchain to help verify identity while keeping data private and secure.
Prompt-Driven Personalisation
Prompt-driven personalisation is a method where technology adapts content, responses, or services based on specific instructions or prompts given by the user. Instead of a one-size-fits-all approach, the system listens to direct input and modifies its output to suit individual needs. This makes digital experiences more relevant and helpful for each person using the service.
Quantum Error Analysis
Quantum error analysis is the study of how mistakes, or errors, affect the calculations in a quantum computer. Because quantum bits are very sensitive, they can be disturbed easily by their surroundings, causing problems in the results. Analysing these errors helps researchers understand where mistakes come from and how often they happen, so they can develop ways to fix or avoid them. This process is crucial to making quantum computers more reliable and accurate for real-world use.
AI for Autonomous Drones
AI for autonomous drones refers to the use of artificial intelligence to allow drones to operate without direct human control. By processing data from sensors and cameras, AI enables drones to make decisions such as navigating obstacles, choosing flight paths, and responding to changing environments. This technology helps drones perform complex tasks safely and efficiently, even in unpredictable situations.
