Quinary (

**base**-**5**or pental) is a numeral system with**five**as the**base**. A possible origination of a quinary system is that there are**five**fingers on either hand. In the quinary place system,**five**numerals, from 0 to 4, are used to represent any real number. Each quinary digit has log_{2}**5**(approx.Also know, what is the base of a number?

In

**mathematics**, a**base**or radix is the**number**of different digits or combination of digits and letters that a system of counting uses to represent**numbers**. For example, the most common**base**used today is the decimal system. Because "dec" means 10, it uses the 10 digits from 0 to 9.What is the base of number system in computer?

We are used to using the

**base**-10**number system**, which is also called decimal. Other common**number systems**include**base**-16 (hexadecimal),**base**-8 (octal), and**base**-2 (binary).1

## What is the base 16 number system?

The hexadecimal numeral system, also known as just hex, is a numeral system made up of 16 symbols (base 16). The standard numeral system is called decimal (base

**10**) and uses**ten**symbols:**0**,1,**2**,**3**,**4**,**5**,6,7,**8**,**9**. Hexadecimal uses the decimal numbers and includes**six**extra symbols.2

## What is the base of hexadecimal number system?

In mathematics and computing, hexadecimal (also base

**16**, or hex) is a positional numeral system with a radix, or base, of**16**. It uses**sixteen**distinct symbols, most often the symbols**0**–**9**to represent values zero to nine, and A–F (or alternatively a–f) to represent values**ten**to**fifteen**.3

## What do you mean by BCD?

Binary coded decimal (

**BCD**) is a system of writing numerals that assigns a four-digit binary code to each digit 0 through 9 in a decimal (base-10) numeral. The four-bit**BCD**code for any particular single base-10 digit is its representation in binary notation, as follows: 0 = 0000. 1 = 0001. 2 = 0010.4

## What is the 8421 code?

**8421 code**.

**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. See also binary-coded decimal, excess-3

**code**, biquinary

**code**.

## What is the gray code?

The reflected binary

**code**(RBC), also known just as reflected binary (RB) or Gray**code**after Frank Gray, is an ordering of the binary numeral system such that two successive values differ in only one bit (binary digit).6

## What is a GREY code?

A

**Gray code**is an encoding of numbers so that adjacent numbers have a single digit differing by 1. The term**Gray code**is often used to refer to a "reflected"**code**, or more specifically still, the binary reflected**Gray code**.7

## What is meant by excess 3 code?

12. The

**Excess**-**3 code**:- It is an important BCD**code**, is a 4 bit**code**and used with BCD numbers To convert any decimal numbers into its**excess**-**3**form ,add**3**to each decimal digit and then convert the sum to a BCD number As weights are not assigned, it is a kind of non weighted**codes**.8

## What is the 2421 code?

**2421 Code**. This is a weighted

**code**, its weight are 2, 4, 2 and 1. A decimal number is represented in 4-bit form and total weight of the four bits = 2 + 4 + 2 + 1 = 9. Hence the

**2421 code**represents decimal number 0 to 9.

## What is not a weighted code?

**Weighted**binary

**codes**are those binary

**codes**which obey the positional weight principle. Each position of the number represents a specific weight. Several systems of the

**codes**are used to express the decimal digits 0 through 9. In these

**codes**each decimal digit is represented by a group of four bits.

## What is 0 and 1 in computer language?

A binary code represents text,

**computer**processor instructions, or any other data using a two-symbol system. The two-symbol system used is often the binary number system's**0 and 1**. The binary code assigns a pattern of binary digits, also known as bits, to each character, instruction, etc.11

## What is a non weighted code?

**Weighted Codes**:-The

**weighted codes**are those that obey the position

**weighting**principle,which states that the position of each number represent a specific weight. In these

**codes**each decimal digit is represented by a group of four bits. There are millions of

**weighted code**The most common one is 8421/BCD

**Code**.

12

## What is BCD code with example?

Short for Binary Coded Decimal,

**BCD**is also known as packet decimal and is numbers 0 through 9 converted to four-digit binary. Using this conversion, the number 25, for**example**, would have a**BCD**number of 0010 0101 or 00100101. However, in binary, 25 is represented as 11001.13

## What is the ascii?

**ASCII**(American Standard Code for Information Interchange) is the most common format for text files in

**computers**and on the Internet. In an

**ASCII**file, each alphabetic, numeric, or special character is represented with a 7-bit binary number (a string of seven 0s or 1s). 128 possible characters are defined.

14

## How many different characters can be represented in a 7 bit character set?

The ASCII table has

**128 characters**, with values from 0 through 127. Thus, 7 bits are sufficient to represent a character in ASCII; however, most computers typically reserve 1 byte, (8 bits), for an ASCII character.15

## What is meant by a character set?

A defined list of

**characters**recognized by the computer hardware and software. Each**character**is represented by a number. The ASCII**character set**, for example, uses the numbers 0 through 127 to represent all English**characters**as well as special control**characters**.16

## What is the UTF 8 character set?

Summary. UTF-8 is a compromise character encoding that can be as compact as

**ASCII**(if the file is just plain English text) but can also contain any**unicode**characters (with some increase in file size). UTF stands for**Unicode**Transformation Format. The '8' means it uses 8-bit blocks to represent a character.17

## What is a character set in HTML?

ASCII was the first

**character encoding**standard (also called**character set**). ASCII defined 128 different alphanumeric**characters**that could be used on the internet: numbers (0-9), English letters (A-Z), and some special**characters**like ! UTF-8 (Unicode) covers almost all of the**characters**and symbols in the world.18

## What is the character set of C?

C Character Set - C Programming Language. character:- It

**denotes**any alphabet, digit or special symbol used to represent information. Use:- These characters can be combined to form variables. C**uses**constants, variables, operators,**keywords**and expressions as building blocks to form a basic C program.19

## What is UTF 8 in HTML?

That meta

**tag**basically specifies what character set is your website written with. Here is a definition of**UTF**-**8**:**UTF**-**8**(U from Universal Character Set + Transformation Format—**8**-bit) is a character encoding capable of encoding all possible characters (called code points) in Unicode.
