ASCII (American Standard Code for Information Interchange) is the most common character encoding format for text data on computers and on the internet. In standard ASCII-encoded data, there are unique values for 128 alphabetic, numeric or special additional characters and control codes. Important PointsA CSV file is a comma delimited ASCII text file. It will open in Excel automatically, because it is made in such a way that Excel can easily parse and display the information in a tabular format. The Rich Text Format (often abbreviated RTF) is a proprietary document file format with published specifications developed by Microsoft Corporation from 1987 until 2008 for cross-platform document interchange with Microsoft productsASCII files are plain text files. They can have extensions . txt or have no extension at all. BINARY files are programs or other non-text files saved in the file format of the application that created them or archived or compressed file formats. Hence CSV, RTF, and TXT file formats contain exclusively the ASCII file format. Therefore the correct options are (B), (D), and E only.
