Answer:
Low Vision Aid for Computer Users
Explanation:
Visually impaired people can use the same low vision aids for viewing a computer screen as they do for regular reading activities. These include eyeglass-mounted magnifiers, handheld magnifiers and stand-alone magnifiers. But also, special software has been developed to display content on the screens of computers and other digital devices in large print. Other applications can read text and other visual content aloud with a synthetic voice. These adaptive low vision devices let partially sighted people do the same computer-related tasks as fully sighted people — such as word processing, creating and using spreadsheets and viewing web pages online.
The informal answer to your question is "clipboard". However, there isn't such a thing as the "clipboard". The people who came up with the idea of the clipboard use that nomenclature to describe the location in memory where that copied data resides. So the formal answer to your question is memory or RAM.
