Any base that is itself a power of 2 can be used to notate binary values. That is, base-4, base-8 (octal), base-16 (hexadecimal), base-32, and so on.
Binary is a base-2 counting system such that each digit represents one of two possible values (0 or 1). When we combine bits we double the number of possible values with each additional bit. Thus 2 bits can represent up to 4 possible values, 3 bits gives us 8 possible values and 4 bits gives us 16 possible values, and so on.
We normally deal with bits in groups of 4 because 2 groups of 4 gives us an 8-bit byte which is the norm for most systems. Thus we can reduce an 8-bit binary value from 8 binary digits to just 2 hexadecimal digits, thus giving us a convenient method of notating binary values with fewer digits and a trivial conversion.
Octal notation isn't used as much as hexadecimal notation, but if we wanted to use a 9-bit byte rather than an 8-bit byte (which is not an uncommon activity), octal notation is more convenient than hexadecimal because the 9-bit values can be treated as being exactly 3 groups of 3 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 number bases are most commonly used in computers?
binary and hexadecimal
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 is 10111010 in hexidecimal?
I assume the number is in binary. Separate the binary number from the right, 4 digits at a time: 1011 1011. Then convert each group of four binary digits to hexadecimal. In this case, 1011 is B, so the answer is 0xBB (the prefix 0x is often used to indicate hexadecimal).I assume the number is in binary.

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 MAC addresses written as six pair of Hexadecimal numbers?
Any data is stored internally in the computer as binary digits, but those are "bulky" - you need 4 binary digits for every hexadecimal digit, so hexadecimal is really a kind of shortcut to write out binary numbers.Decimal is another option, but conversion between binary and decimal is more cumbersome than with hexadecimal. Therefore, for the new IP addresses (IP version 6), they decided to write them down in hexadecimal, instead of the decimal that is used for IPv4.
Why hex code use in micro-controller?
When you work in the field of microcontrollers, you have to deal with the hexadecimal code. Some people find it very confusing, but if you know the basics, it will be really easy for you to understand. The Intel Hex format is a standard for storing binary code in text format. It is widely used in programming microcontrollers. The Intel Hex code is used on manufacturers’ websites to provide firmware upgrades and data sheets. The Intel Hex format is also referred to as Bin HEX, u-code, or u-hex.
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.
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.
Where is hexadecimal is used?
Hexadecimal is used whenever we want to notate a binary value because each hex digit maps directly with each 4 bit nybble (half a byte). A 64-bit binary value can therefore be reduced to a more concise 16-digit hex value.
What are number systems use in computer to store data and perform calculations?
Binary number system ,which has only two digits 0 and 1.
What number system does subtraction occur in?
Im not sure, but i think all. im sure its used in binary, octal, decimal and hexadecimal
