depends on the depth of memory, N address lines can map 2 Power N locations.
Hexadecimal is commonly used in comoputing to represent a memory byte.
HI I am Ahtarva,The addressibility is how many bits does that particular processor or micro-controller's architecture use to specify the address of a memory location in the memory. For example if someone say that addressibility is 8 bit then your memory address contains 8 bits and at maximum you have 2^8 different memory locations (or say memory addresses in your device). Here 2^8 is called Address space.
An address in C or C++ is the location in memory of an object or function. An address is the contents of a pointer, as opposed to the contents of the memory location pointed to by the pointer.
If there are 2^n cells then you need at least n bits to address each cell individually. For example, if there 2^32 cells then you need at least 32 bits to address each of the cells. 2^32 = 4,294,967,296 cells The cells are numbered the range 0 to 4,294,967,295 (inclusive). In hexadecimal notation this range becomes 0h to FFFFFFFFh. The upper bound has exactly 8 hex digits. Each hex digit represents the 4-bit binary value 1111. 8 x 4 bits = 32 bits. QED.
pointer
group of consecutive memory that has had physical memory assigned to it
If the architecture allows each individual byte to be adressed then there are 4,000,000 possible addresses ranging from 0 to 3,999,999. So the largest address is 3,999,999 which is 3D08FF in hexadecimal representation
It refers to Memory Address since variable will never be a NUMBER it is Memory Address like an HexaDecimal Address of FFFFH. Eds
Yes. We could use decimal notation but hexadecimal is more convenient because it requires fewer digits and more closely reflects the way the machine addresses memory using its native binary notation. For instance, a 64-bit address in decimal requires 20 decimal digits (including leading zeroes) but only 16 hexadecimal digits. Moreover, the hexadecimal value can be easily translated into the actual binary value used by the machine because each hex digit maps 1:1 with every nybble of the binary value. A nybble is half-a-byte (4-bits). Since each address typically represents an 8-bit byte, the value of that byte can also be expressed using just 2 hexadecimal digits (00 to FF) whereas decimal notation would require 3 digits (000 to 255). If we used decimal notation to present the contents of a block of memory, then we wouldn't be able to fit as many columns of data on the screen at once. More importantly, when we look at the contents of memory we're generally more interested in what the computer sees, and hexadecimal notation more closely reflects what the computer sees.
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.
In the context of computer memory, an address is used to access the computer's primary storage memory. These addresses consist of fixed-length digits displayed as unsigned integers.
Hexadecimal number system is a number sytem with a Base of 16. The 'regular' system which we use every day is base-ten (decimal), with the digits 0-9.Having a base 16 system makes it easier to represent values of computer memory, as computers deal in binary (base 2), where every value is either one or zero (on or off).With hexadecimal, the digit values range from zero to fifteen, so symbols are needed to represent ten, eleven, ... fifteen as single digits. The letters A through F were chosen, so:A represents tenB = elevenC = twelveD = thirteenE = fourteenF = fifteen
Port and memory addresses are expressed as Hexadecimal Numbers
I think it's a hexadecimal memory reference.

Hexadecimal is only preferred to machine code but not as preferred to C++, Pascal, Linux
