A dynamic workload is ephemeral and loads and runs only when needed. A static workload is always on and running, such as an operating system (OS), email system, enterprise resource planning (ERP), customer relationship management (CRM) and many other applications central to a business's operations. As one example, workloads may be classified as static or dynamic. Workloads are created to perform myriad different tasks in a countless variety of ways, so it is difficult to classify all workloads into a single set of uniform criteria. Standardized metrics used to measure and report on an application's performance or load are collectively referred to as benchmarks. For example, a web server application might gauge load by the number of webpages the server delivers per second, while other applications might gauge load by the number of transactions accomplished per second with a specific number of concurrent network users. A heavy workload demands significant amounts of computing resources.Ī workload's tasks vary widely depending on the complexity and intended purpose of the application. A light workload accomplishes its intended tasks or performance goals using relatively little computing resources, such as processors, CPU (central processing unit) clock cycles, storage I/O (input/output) and so on. Broadly stated, an application's workload is related to the amount of time and computing resources required to perform a specific task or produce an output from inputs provided. Workload can also refer to the amount of work (or load) that software imposes on the underlying computing resources. Today, the terms workload, application, software and program are used interchangeably. A workload can be a simple alarm clock or contact app running on a smartphone, or a complex enterprise application hosted on one or more servers with thousands of client (user) systems connected and interacting with the application servers across a vast network. In computing, a workload, typically, is any program or application that runs on any computer. It can be a bit of a bad experience as users can still tab to the link.įor accessibility, what I see used today is a combination of styles to hide an element while being visible to screen readers. The important difference with text-indent is that it will often be read by screen readers. text-indent: -9999px is one other that is roughly equivalent. Keep in mind what visually-impaired users will experience. ![]() There are a lot of detailed answers here, but I thought I should add this to address accessibility since there are implications.ĭisplay: none and visibility: hidden may not be read by all screen reader software. visibility: hidden has the additional benefit of not capturing JavaScript events, whereas opacity: 0 captures events Because toggling from visibility: hidden to visibility: visible allow for CSS-transitions to be use, whereas toggling from display: none to display: block does not. However, opacity: 0 is functionality equivalent to visibility: hidden and does not re-trigger the layout step.Īnd CSS-transition property is also important thing that we need to take care. ![]() Visibility: hidden and display: none will be equally performant since they both re-trigger layout, paint and composite. Interesting information about visibility: hidden and display: none properties It will leave the element in the normal flow of the page such that is still occupies space.Īn element is not visible and Element’s space is allocated for it on the page. There will be no space allocated for it between the other elements. It will remove the element from the normal flow of the page, allowing other elements to fill in.Īn element will not appear on the page at all but we can still interact with it through the DOM. Maybe this would be useful for some type of watermarking, or if you wanted to hide a copyright notice that would show up if a carelessly user copy/pasted your content? This is usually not the behavior you want (but maybe sometimes it is?).Īnother difference is if you select the text, then copy/paste as plain text, you get the following: 1st link. However, there is a difference between 2 and 3: in case 3, the mouse will still switch to the hand when hovering over the link, and the user can still click on the link, and Javascript events will still fire on the link. The difference between 1 and 2 has already been pointed out (namely, 2 still takes up space). (Be sure to click "Run code snippet" button above to see the result.)
