Vezérljel

Vezérljel, also known as vezérlőjel, is a Hungarian term that translates to "control character" or "control code" in English. It refers to a specific type of character used in computing and telecommunications to control the behavior of devices, such as printers, terminals, and other peripherals. These characters are not visible when displayed on a screen but serve essential functions in data transmission and processing.

Control characters are typically represented by non-printable ASCII codes, ranging from 0 to 31 and 127 in the ASCII table. Some common examples include:

- Null (0): Represents the absence of a character.

- Bell (7): Produces an audible or visible alert.

- Backspace (8): Moves the cursor one position to the left.

- Horizontal Tab (9): Moves the cursor to the next tab stop.

- Line Feed (10): Moves the cursor to the next line.

- Carriage Return (13): Moves the cursor to the beginning of the line.

- Delete (127): Deletes the character at the cursor position.

Vezérljel characters are crucial in various applications, including text formatting, data transmission protocols, and the operation of hardware devices. They ensure that data is correctly interpreted and displayed, facilitating smooth communication between different systems and components. Understanding and correctly using vezérljel characters is essential for anyone working in fields such as software development, telecommunications, and data processing.
