i) Progress Bar: A progress bar is a graphical control element used to visualize the progression of an extended computer operation, such as a download, file transfer, or installation. For example, when you're downloading a file, a progress bar will typically appear showing the percentage of the file that has been downloaded and how much is remaining.

ii) Toast: In the context of user interface design, a toast is a small message that pops up on the screen to display an information or feedback. For example, when you send an email, a small message might pop up at the bottom of your screen saying "Email sent successfully."

iii) Radio Button: A radio button is a type of graphical user interface element that allows the user to choose only one of a predefined set of mutually exclusive options. For example, when filling out a survey, you might be asked to select your gender with the options "Male", "Female", and "Other" represented as radio buttons. You can only select one of these options.

iv) Check Box: A check box is a graphical user interface widget that permits the user to make a binary choice, i.e. a choice between one of two possible mutually exclusive options. For example, when signing up for a service online, there might be a check box that you can tick to agree to the terms and conditions.
