Specifically, control characters are those with ASCII values from 0 to 31, and the <strong>Data characters<\/strong> are those with ASCII values from 32 to 127.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Control Characters<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Control characters in NVT are non-printable characters that are used for controlling devices and managing the flow of data. These characters are in the <strong>ASCII range from 0 to 31<\/strong>. Examples include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>NUL (Null)<\/strong> &#8211; ASCII value 0, used to represent the absence of a character.<\/li>\n\n\n\n<li><strong>BEL (Bell)<\/strong> &#8211; ASCII value 7, used to make a sound or alert.<\/li>\n\n\n\n<li><strong>ESC (Escape)<\/strong> &#8211; ASCII value 27, used to initiate an escape sequence that modifies the interpretation of subsequent characters.<\/li>\n\n\n\n<li><strong>CR (Carriage Return)<\/strong> &#8211; ASCII value 13, moves the cursor to the beginning of the line.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Control characters are primarily used for managing the data stream, indicating actions like the beginning or end of a transmission, starting or stopping certain operations, or formatting text.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Data Characters<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Data characters are printable characters that correspond to letters, digits, punctuation marks, and other symbols. These characters are in the <strong>ASCII range from 32 to 127<\/strong>. Examples include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A-Z<\/strong> (uppercase letters)<\/li>\n\n\n\n<li><strong>a-z<\/strong> (lowercase letters)<\/li>\n\n\n\n<li><strong>0-9<\/strong> (digits)<\/li>\n\n\n\n<li><strong>Symbols<\/strong> such as <code>@<\/code>, <code>#<\/code>, <code>$<\/code>, etc.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Data characters represent the actual content that is transmitted over the network, and they are the characters typically seen in user interfaces and communication messages.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">NVT in Action<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The NVT protocol operates in a way that allows these two types of characters to be transmitted clearly over a network. Since control characters manage the session and data characters carry the meaningful content, the distinction between the two is essential for correctly interpreting the data flow.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For instance, when transmitting text over a network, data characters are sent as part of the message, while control characters ensure the transmission occurs properly, adjusting timing or formatting when necessary.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How are control and data characters distinguished in NVT?
