Latency is the delay between an input into the system and the desired outcome. Although the latency definition is simple, there are several more complex types of latency that you should familiarize yourself with. Latency itself comes in many forms because it can affect many different areas of a network. Below are some of the most common types of latency that your system may experience. Once you have these definitions memorized, you can better prevent and solve latency problems for your coming digital candystorms.
Latency And Throughput
Latency and throughput are two of the most fundamental measures for network performance, whether you use HPUX or something else. These two concepts are similar, but not exactly the same. Latency measures the amount of time between action start and finish. Throughput, on the other hand, is the number of times the action that latency is measuring actually happens in a set amount of time. It is important to remember that latency and throughput are related, but measure two separate things.
WAN Latency
WAN latency is a specific type of latency caused by high traffic volume. This can happen on any type of browser, including Yesware Chrome. WAN latency happens when a netowrk is busy dealing with an inordinate amount of traffic. This leads to request being delayed, because the hardware is unable to handle all of the expected functions at maximum speeds. This type of latency effects wired networks as well, because the whole network operates together. That is why it is a must know.
Network Latency
Network latency is a term used to describe any type of delay that happens in data communication over a network. It is the broadest term and most commonly referred to. Network latency can be tested through ping tests and trace routes, which may allow you to find the source of the problem and minimize the effects. If you use any of the Filesync alternatives, you will know that network speed is very helpful. This is an important latency definition to know as a tech beginner because you will likely come across it in the future.
Packet-Switched Networks
In a packet-switched network, whether using netbeans or not, network latency is measure one way or round trick delay time. One way latency measurements refer to the time from the sender to the destination. Round trip delay time measurements of latency note the one way from source to destination and add it to the one way latency from destination to sender. Round trip latency is much more frequently used as the means of latency measurement. Ping does not perform packet processing, so it is important to be familiar with how to measure latency in packet switched networks.
Internet Latency
Internet users everywhere will know the frustration of a slow internet connection, that is why overclocking CPUhas become much more common. Sometimes, however, it is not the connection that is bad. Internet latency is a type of network latency that specifically effects the Internet. There are many factors that can play into an increase in latency, such as distance, hardware and transmission issues. If your Internet ever seems to be running more slowly than usual, Internet latency may be the culprit.
Computer System Latency
Computer system latency has to do with the operating system that you are using. This is the delay between the input and output of a program or other type of software. The most common cause of this type of latency is mismatched microprocessors, shoddy hardware and processing load of the computer, according to ITAA advocacy. The severity of computer system latency can vary, but it is often easy to spot for the average computer user.
Mechanical Latency
Mechanical latency is the delay in physical operations. When it comes to computers, this will have to do with hardware. For example, a hard drive has several moving parts. If there is a delay between the shift of one gear and the shift of another, this would be considered mechanical latency. See how users avoid this by using an overclocked CPU to boost performance. If the moving parts of a computer are not working properly, this can greatly affect its operation.
Audio Latency
Audio latency is another common issue many people may experience on their laptops or even over the phone. The time it takes sound to travel from its source to its intended audience can be affected by audio latency. This is the delay between you speaking into a phone or microphone and the sound reaching the other person or computer. In some cases, this can happen with radio broadcasting too. This type of latency can be tested easily most people will notice a lag of as little as 30 milliseconds when it comes to sound.
Although the latency definition is simple, there are several other subcategories of latency to consider whether you use a VAX computer or a Dell. Hopefully, we have shed some light on the different types so that you can better understand these computer issues. Now, you can better identify the source of the problem when dealing with latency.
