What is the special code called used by computers?

Computers use a special code of their own to express the digital information they process. It's called binary code because it is made of only two symbols — 0s and 1s. (The "bi" in "binary" means two.) Everything in the computer is represented by this binary code.

What is the number 9 in binary code?

9 in binary is 1001.

What are the zeros and ones that make up computer data called?

Computers use binary - the digits 0 and 1 - to store data. A binary digit, or bit , is the smallest unit of data in computing.

What type of code is in 1s and 0s?

binary code, code used in digital computers, based on a binary number system in which there are only two possible states, off and on, usually symbolized by 0 and 1.

Is binary code still used?

Binary numbers can be considered the very basic representation of a number in an electronic device. Converting to and from a decimal will be covered in another article. ... The very first computers used binary numbers, and they are still used today.

How do you write 21 in binary?

21 in binary is 10101.

What does 110101 mean?

In other words: 110101 in binary is equivalent to 53 in our usual decimal system of numbers.

What exactly is binary?

Binary describes a numbering scheme in which there are only two possible values for each digit: 0 and 1. The term also refers to any digital encoding/decoding system in which there are exactly two possible states.

Is computer code just ones and zeros?

A binary code represents text, computer processor instructions, or any other data using a two-symbol system. The two-symbol system used is often "0" and "1" from the binary number system. ... A bit string, interpreted as a binary number, can be translated into a decimal number.

What is binary data in computer?

Binary data is data whose unit can take on only two possible states, traditionally labelled as 0 and 1 in accordance with the binary numeral system and Boolean algebra.

What is the 8421 code and how is it used?

In other words, the BCD is a weighted code and the weights used in binary coded decimal code are 8, 4, 2, 1, commonly called the 8421 code as it forms the 4-bit binary representation of the relevant decimal digit.

How do you write code 8421?

8421 code A weighted code in which each decimal digit 0 through 9 is represented by a four-bit codeword. The bit positions in each codeword are assigned weights, from left to right, of 8, 4, 2, and 1.

Which of the following code is known as the 8421 code?

BCD code or Binary coded Decimal codes. It is a numeric weighted binary codes, where every digit of a decimal number is expressed by a separate group of 4-bits. There are various BCD codes like 8421, 2421, 5211, etc. The BCD code is also known as the 8421 code.
