1111111111111111 (216 - 1 = 65535)
In unsigned notation, 0xFFFF (65,535 decimal) is the largest value that will fit in a 16-bit register. In signed notation, 0x7FFF (32,767 decimal) is the largest because the most-significant bit denotes the sign.
In C: result = value & ~0xFFDF

Quite simply, a 16-bit compiler is a compiler for a 16-bit machine.
16 bit compilers compile the program into 16-bit machine code that will run on a computer with a 16-bit processor. 16-bit machine code will run on a 32-bit processor, but 32-bit machine code will not run on a 16-bit processor. 32-bit machine code is usually faster than 16-bit machine code.-DJ CraigNoteWith 16 bit compiler the type-sizes (in bits) are the following: short, int: 16long: 32long long: (no such type)pointer: 16/32 (but even 32 means only 1MB address-space on 8086)With 32 bit compiler the object-sizes (in bits) are the following:short: 16int, long: 32long long: 64pointer: 32With 64 bit compiler the object-sizes (in bits) are the following:short: 16int: 32long: 32 or 64 (!)long long: 64pointer: 64[While the above values are generally correct, they may vary for specific Operating Systems. Please check your compiler's documentation for the default sizes of standard types]Note: C language itself doesn't say anything about "16 bit compilers" and "32 bit compilers"

The number of data lines required in a 16-bit microprocessor is 16, in the internal view, but could be something else, such as 8, in the external view. In the 8086/8088, the processor is 16 bits, and its internal data bus is 16 bits. The 8086 provides 16 bits on the external bus, but the 8088 provides 8 bits, even though they are the same internal processor - the 8088 simply uses two memory cycles to move one word. The largest number that can be represented on a 16 bit bus depends on the interpretation of that number. An unsigned 16 bit number ranges from 0 to 65535, so 65535 is the largest value when unsigned. A 16 bit two's complement signed number ranges from -32768 to +32767, so +32767 is the largest value when signed.
That would be 216 - 1, or 65535.
For an unsigned integer, that would be 216-1. For a signed integer in 2's complement notation, the largest number would be 215-1.
The largest binary number that can be expressed with 16 bits is 1111111111111111, which is equivalent to 65,535 in decimal. This number uses all 16 bits set to 1. In general, for an n-bit binary number, the maximum value is (2^n - 1). Thus, for 16 bits, it is (2^{16} - 1 = 65,535).
In a 16 bit number there must be from zero to 16 '1'. If a bit does not have value zero then it has a value of 1. Nothing else can be represented by a bit. Example 0000 is a 4 bit number. Each bit is a zero. 1010 is also a four bit number. 0000111100001111 is a 16 bit number. 1100110011000001 is also a 16 bit number.
The largest number which can be stored in an 8 bit memory byte is 255. The largest prime number below 255 is 251.
The largest number which can be stored in an 8 bit memory byte is 255 . The largest prime number below 255 is 251.
