Inside the computer everything operates with the notion of on or off. With this in mind, the use of binary is really self-explanatory as it consists of only 1s and 0s. Hexadecimal, like octal, works very well also as they're both based on powers of 2 (8 and 16) it's easy to use these as forms of shorthand for binary.

What number bases are most commonly used in computers?
binary and hexadecimal
Why is hexadecimal often used instead of denary to represent binary numbers for a human audience?
Hexadecimal is often used instead of denary to represent binary numbers because it provides a more compact and readable format. Each hexadecimal digit corresponds to four binary digits (bits), making it easier to represent large binary values without lengthy strings of zeros and ones. This simplification helps reduce the potential for errors when interpreting or writing binary data, especially in programming and digital electronics. Additionally, hexadecimal aligns well with the way computers process data, which is inherently binary.
Why is it possible to have decimal numbers?
It is possible to have numbers in ANY base. Binary, octal and hexadecimal are used extensively in computers. Furthermore, the base can be any positive number - it does not even need to be rational.
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.
Is the octal number system used for business dealing in Pakistan?
the octal numbering system is not used for dealing it was once used for computers but has been replaced with binary and hexadecimal because of its complexity and how it does not relate to binary at all hexadecimal and binary go together way better...
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.
Why are IP addresses converted into binary format?
ip adresses are put into the binary format so computers can make sense of them. hexadecimal is used for the same purpose.
Are binary numbers used mostly in the science of computers?
No. All computers only understand binary, which is 0 as "off" and 1 as "on."
Why do you use octal and hexadecimal number system as shortcut notation?
Memory dump which are in binary numbers would have many numbers of 0s and 1s. working with these numbers would be very difficult. Hence two number system hexadecimal and octal number system is used because these numbers are inter convertible with binary numbers by the concept of bits.
Why are different number systems used in computers?
It turns out that using the binary system - base 2 - requires circuits that are extremely simple, compared to circuits that manage decimal (base 10) numbers. So, internally, computers do lots of stuff in binary. Octal and hexadecimal numbers are used as shorthand for binaries, to make them readable for humans. This is because on average, a number written in binary digits requires 3-4 times as many digits as a number in decimal. Each octal (base 8) number simply represents three bits (binary digits); while each hexadecimal (base 16) number represents 4 bits.
Why is Hexadecimal used?
It is used because it is easier to convert to and from binary to hexadecimal than decimal, and it uses less characters than binary. For instance: decimal: 65535 hex: FFFF binary: 1111111111111111
What are number systems use in computer to store data and perform calculations?
Binary number system ,which has only two digits 0 and 1.
