Data rate is the speed at which information is exchanged between electronic devices, including internet connections, hardware components, and electronics. It affects website optimization, graphics quality, and overall performance. Manufacturers measure efficiency and classify products. Actual performance differs from maximum possible speed.
Data rate is a technical term that describes how fast information can be exchanged between electronic devices. In many cases, this term is used to describe the speed of the Internet connection and how quickly a consumer can upload or download files. Hardware components such as hard drives, memory and video cards also handle data rates as they process information, but so do electronics such as televisions, video games and radios. Using a calculation for this rate, manufacturers are also able to measure the efficiency of their products and classify them into categories.
Internet connections are measured in terms of data speeds. A 56k dial-up modem, for example, can receive a maximum of 56 kilobits per second when properly installed. The information is sent in small chunks of data called packets, and because it can travel thousands of miles or kilometers across various phone lines, there is never 100% optimization. As speeds increase in the case of a cable or digital subscriber line (DSL) modem, packet losses are even greater. While a term like 3 gigabytes (3G) refers to the maximum possible speed, data speed refers to actual performance.
Nearly every aspect of the internet relates to data charges in one form or another. Website builders optimize web layouts so that pages load quickly when a consumer clicks on a link, and larger websites require near-constant attention. For example, if a person were the only one visiting a web address, the page could load instantly. When thousands of people click on that particular link, the incoming data rate needs to be optimized for that link. This helps businesses decide what type of graphics to use online, how to host their websites, and how much bandwidth needs to be allocated.
Computers and electronics also measure data rates in other ways. A computer hard drive can normally send information to the processor in milliseconds, but other programs running in the background could drastically reduce the response time. Graphics cards are also heavily dependent on data rates to deliver the correct visuals in games and movies. In many cases, hundreds of frames per second (FPS) are sent to the monitor, and as the rate decreases, the image becomes blurry or distorted. Memory cards also have a large factor in a computer’s overall data rate as they deliver information from one piece of hardware to another.
