Line editor and screen editor are two main types of text editors used in computing. Line editors allow you to edit one line at a time and are usually used for smaller files and code. Screen editors, on the other hand, are used to edit whole blocks of text or larger files. They provide more features than a line editor, such as the ability to view and edit multiple lines at once, add formatting and search and replace text.
Line editors are often used to edit code, as they are simple and provide quick editing capabilities. Screen editors, on the other hand, provide more features and therefore make it easier to edit texts that are longer in length and require formatting capabilities. For instance, most people prefer to use a screen editor when writing blog posts or emails, as they provide more flexibility.
At the end of the day, it comes down to personal preference. If you're looking for an editor to quickly make changes to short blocks of code, a line editor might be the best choice for you. If you're looking for a more powerful editor for longer texts, then a screen editor might be the way to go.
