There are several ways that written text is converted into digital form or data.
1. Word processing is a term to describe how words are typed into a computer application and then converted into fancier looking text. WP data can then be printed by the computer through a LASER printer or the data can be stored on the computer or even sent in digital form from one computer to another computer / printer / storage device somewhere else on the planet.
2. Scanning a written word book through a convertor or scanner uses simmilar technology to a photo copier to input the written words into digital form
Data refers to information that can be represented in various forms, including text, numbers, graphics, sound, and video. When this information is converted into a digital format, it is expressed as discrete digits, typically in binary code (0s and 1s). This digital representation allows for easier storage, processing, and transmission across computers and networks. Ultimately, data serves as the foundation for computing and digital communication.
Data that has been converted into discrete digits, such as text, numbers, graphics, sound, and video, is referred to as digital data. This conversion process allows various forms of information to be represented in a format that computers can process and store. Digital data is typically composed of binary code, which consists of 0s and 1s, enabling it to be easily manipulated, transmitted, and preserved across different devices and platforms.
The delimiter used in the data being converted from text to columns can vary depending on the format of the data. Common delimiters include commas (,), tabs (\t), semicolons (;), and spaces ( ). In spreadsheet applications like Excel, you can specify the delimiter when using the "Text to Columns" feature to separate the data correctly.
Document processing is an area of study and a set of production methods for converting an analogue document to a digital format. Unstructured data is converted through Intelligent Document Processing (IDP). Documents are used to store and communicate data. Manual forms and analogue data are converted to digital format so that they can be integrated into day-to-day business procedures.

Analogue data is data in a continuous stream that has an infinite range of values that change gradually. One example of analogue data is the sound of a person talking. We are capable of handling analogue data, yet computers require analogue data to be converted into digital data for processing. Digital data is discrete data that is used in computers to handle all sorts of digital media, including text, graphics and audio. It only exists in two forms - on and off. This is represented with two digits- 1s and 0s - in the binary format. Since digital data is discrete, files saved in this format can be copied perfectly with no degradation.
The process of changing plain text into cipher text is called encryption. During this process, data is transformed using an algorithm and a key, making it unreadable to unauthorized users. The resulting cipher text can only be converted back to plain text through decryption, which requires the appropriate key. This is a fundamental technique used in digital security to protect sensitive information.
A modem (which stands for Modulator-Demodulator) converts digital data from the computer to analog data compatible with the telephone system. The analog signal is converted back into digital data on the other end of the call.
When you convert a memo data type to text, any text stored in the memo field will be converted to plain text format. Any formatting, such as line breaks or special characters, may be lost during this conversion.
Because in order to preserve the original sound, a digital sampling rate must be twice the frequency of the analog signalAnalog data is smooth and continuous, where as digital data, such as the binary data used in computers, has distinct gradations. The process of producing digital data by measuring data at a series of representative points is called sampling.
