Synchronous programming refers to sequentially executed operations. 

Unlike asynchronous programming, where programs simultaneously run multiple operations, a synchronous model implements a blocking mechanism, ensuring tasks execute orderly to enhance code readability and predictability. 

For example, a web page aiming to load three images in sequence would employ synchronous programming to ensure each image loads completely before the next one begins. This process preserves the intended display order and delivers a systematic viewing experience for the user. 

However, synchronous programming can sometimes limit a website's responsiveness and performance. If a task takes longer to complete, it stalls subsequent operations, leading to lags in the site or application performance. To mitigate such delays, developers often employ asynchronous methods to allow for concurrent task execution, eliminating blocking mechanisms and improving responsive design.
