What technique is utilized to convert data into a coded format in operating systems?

• A. Data compression
• B. Encryption
• C. Data visualization
• D. Data migration

Answer: (B)

The technique that converts data into a coded format in operating systems is encryption. Encryption is a security measure used to protect sensitive information by transforming readable data into an encoded format that can only be read or deciphered with a specific key or algorithm. This process ensures confidentiality and integrity, making it essential for protecting data from unauthorized access, especially in environments where data is transmitted over networks or stored on devices that may be vulnerable to interception.

In contrast, data compression reduces the size of data to save storage space or speed up transmission, but it does not secure the data. Data visualization deals with presenting data in a graphical format to make it easier to understand and analyze, rather than converting data into a coded format. Data migration involves moving data from one storage location to another, which does not inherently involve encoding or securing the data. Thus, encryption is the correct choice as it specifically addresses the conversion of data into a coded format for the purposes of protection and privacy.
