What is the highest digit that can be used in each place value?

In the decimal number system, the highest valued digit is 9. The highest digit that ever appears in any one 'place' of a number is one less than the 'base' of the number. The numbers that everyone is most familiar with ... the numbers you see around you every day ... are numbers written in the 'decimal' system, using the 'base' of 10. So the highest digit in any one place is 9. 'Binary' numbers ... the form most used to represent numbers inside digital circuits and computers ... are constructed in base 2. So the highest digit in any one place is 1, and each of these numbers is just a string of 1's and zeros. Digits can be even higher than 9 in number systems that use other bases. For example, the hexadecimal system (often used in computer science to represent binary numbers) is base 16, so in that case the highest valued digit is "F" which has a value equivalent to 15 in a decimal representation. As an example, the number "FA" hexadecimal, has decimal value 15*16 + 10 = 250.


How many ways are there to write a 3 digit positive integer using digits 1 3 5 7 and 9 if no digit is used more than once?

This is a question of permutations; the answer is equal to the factorial of 5 (number of digits) divided by the factorial of 3 (number used in each selection), written 5! / 3!. This equals 120 / 6, or 20 ways.

Where do they use hexadecimal system?

Computers store data in binary digits - ones and zeroes. It is mainly here that hexadecimal is used, as a shortcut for binary; each hexadecimal digit corresponds to four binary digits.


How many different symbols are used in the hexadecimal system?

There are 16 symbols.


How many hex digits are typically used in computing?

Used for what???The hexadecimal system is just a way to represent information. Each byte requires two hexadecimal digits. Modern computers have billions of bytes in RAM, and often a trillion or more bytes on the hard disk, so that would be billions or trillions of hexadecimal digits. Some examples of things that are often represented as hex digits: * An IPv6 address has 16 bytes - so, 32 hex digits. * A MAC address has 6 bytes (12 hex digits). * A register has a few bytes. The size varies, but is often 2-8 bytes.

What are the advantages of hexa decimal number system?

Computers do much of their processing in binary. Hexadecimal is used as a kind of shortcut (easier to read for humans): each hexadecimal digit represents four binary digits.


What is the meaning of binary in computer science?

Binary is a number system which only has two possible digits. That corresponds with the on and off signals in computers, where 0 means off and 1 means on. Binary digits are often used in convenient groupings. For instance, 4 binary digits (a "nybble") represent a single hexadecimal digit. Hexadecimal is a 16-base number system with digits 0 to 9, A to F, thus giving 16 possibilities. Eight binary digits, or two hexadecimal digits, is another convenient grouping called a byte. A byte represents 256 possibilities.


What is a hexdecimal system?

That is "hexadecimal". The decimal system we often used is based on powers of 10 (each place-value is worth 10 times as much as the one to the right); the hexadecimal system is based on powers of 16, and therefore needs 16 different digits. The "digits" commonly used are the digits 0-9, the "A" for 10, "B" for 11, ... "F" for 15.This is commonly used in computers, as a sort of shorthand for writing binary (base-2) numbers.


What are hexadecimal numbers?

hexadecimal numbers are the a positional numeral system with a radix, or base, of 16.16 distinct symbols are used in the hexadecimal numbers.


How many digits in numeric system?

It varies depending on the base you are using. The standard is the decimal system (because of the 10 fingers on our hands) 0-9. Some other used systems (especially for computers) are binary 2, octal 8, hexadecimal 16 using the digits: 0-9,A-F.


What is radix in number system?

The radix refers to the base of a number system: the total number of possible digits. The decimal number system that we all use is base ten, as it has ten distinct digits (0,1,2,3,4,5,6,7,8,9). Commonly used bases in computing include binary, octal, and hexadecimal, which have two, eight, and sixteen digits, respectively.


What are the advantages of hexadecimal number system?

Each hexadecimal digit represents four binary digits (bits) (also called a "nibble"), and the primary use of hexadecimal notation is as a human-friendly representation of values in computing and digital electronics. For example, binary coded byte values can range from 0 to 255 (decimal) but may be more conveniently represented as two hexadecimal digits in the range 00 through FF. Hexadecimal is also commonly used to represent computer memory adresses.
