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
How hexadecimal conversion use in computer?
Hexadecimal conversion is widely used in computing as a more human-friendly representation of binary data. Each hexadecimal digit corresponds to four binary digits (bits), making it easier to read and write large binary numbers. It is commonly employed in programming, memory addressing, and color codes in web design, where compactness and clarity are essential. Additionally, hexadecimal is used in debugging and understanding low-level data structures and machine code.
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 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 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.
Why you use hexadecimal and octal systems?
Hexadecimal and octal systems are used primarily in computing and programming because they provide a more compact representation of binary data. Hexadecimal (base 16) simplifies the representation of binary values, allowing four binary digits to be represented by a single hexadecimal digit, making it easier for humans to read and understand. Octal (base 8), while less common today, was traditionally used in computing due to its straightforward conversion from binary, grouping bits into sets of three. Both systems help streamline coding, debugging, and memory addressing processes.
