Correct Answer - Option 3 : Binary

• A binary number system is one of the four types of number systems.
• In computer applications, where binary numbers are represented by only two symbols or digits, i.e. 0 (zero) and 1(one).
• The binary numbers here are expressed in the base-2 numeral system. For example, (10110110)2 is a binary number.

• Internally the computer coding scheme represents data in Binary form
• The computer is an electronic device, which accepts data, processes it and outputs the results in the form of reports.
• The original objective of computers was to make fast calculations, but modern computers besides performing fast calculations can store large volumes of data, process and retrieve data as and when desired.
• Hence computers are also known as data processors.
• The computer is a system. A system is a group of integrated parts to achieve a common objective.
• The computer is made up of integrated parts (input, control, ALU, storage, and output unit).
• All the parts work together to process data.
• The computer accepts input and outputs data in an alphanumeric form. Internally it converts the input data to meaning binary digits, performs the instructed operations on the binary data, and transforms the data from binary digit form to understandable alphanumeric form.
