Test: Understanding Data - 1 - CUET Humanities MCQ

Data without any meaning is useless. Once the data is processed, it becomes meaningful and is called information.

Data represent raw facts, whereas information is the processed meaningful data.

During the processing of data, programs and processed information are held temporarily in RAM.

The working-storage section describes data records that are not part of the data files but are developed and processed by a program or a method. It also describes data items whose values are assigned in a source program or a method and do not change during the execution of the object program.

In this system, data are analysed and reports are generated, which are used for the assessment of the situation for decision making.

The data that is raw, when processed, is converted to information that is in an organized format.

All are the properties of Metadata.

• RAW is a data type used to store binary data, or data which is byte oriented.
• The char is a fixed-length character data type, the varchar is a variable-length character data type.
• Numeric is anything of, relating to, or containing numbers.

So, option (1) is correct.
