0xA7DF has the bit pattern: 1001011111011111.
The hexadecimal of black, assuming that "black" is an ASCII character string is 0x626c61636b. If you mean RGB, it is R=00H, G=00H, B=00H, or 000000H combined.
hexadecimal can express 16 bit binary in 4 place form, not 16.
A binary number system has two states '0' '1' for a long word in bits it can be as follows 101010101010101010101011 intimidating RIGHT? it can be represented in groups of 3 bits in octal 10/010/101/010/101/010/101/011= 22525253 digital or in group of 4 bits as 10/1010/1010/1010/1010/1010 = 2AAAAA 111 =7 octal 1111=f F in hexadecimal numbers 1000 =8 1010 =10 or A
16 is the 4th power of 2. So a hexadecimal number is converted to binary by replacing each hex digit by the 4-bit binary number having the same value. Conversely, in converting binary to hexadecimal, we group every 4 bits starting at the decimal (binary?) point and replace it with the equivalent hex digit. For example, the hexadecimal number 3F9 in binary is 1111111001, because 3 in binary is 11, F (decimal 15) is 1111, and 9 is 1001.
0xc = 1100 Hexadecimal digits use exactly 4 binary digits (bits). The 0x0 to 0xf of hexadecimal map to 0000 to 1111 of binary. Thinking of the hexadecimal digits as decimal numbers, ie 0x0 to 0x9 are 0 to 9 and 0xa to 0xf are 10 to 15, helps with the conversion to binary: 0xc is 12 decimal which is 8 + 4 → 1100 in [4 bit] binary.

Five of them.
The hexadecimal of black, assuming that "black" is an ASCII character string is 0x626c61636b. If you mean RGB, it is R=00H, G=00H, B=00H, or 000000H combined.
If it is unsigned representation (meaning high bit is not sign bit) then it is 7F which has a decimal equivalent of 127. If it is a signed number (meaning high bit is sign bit) then numbers range from decimal -64 to +63
1100
It is 1100.
since bits are 0 & 1 in binary then 11111111 in binary = 256 in decimal = 377 in octal = FF in hexadecimal
7F
hexadecimal can express 16 bit binary in 4 place form, not 16.
we use LDA ## where ## is an 8 bit hexadecimal data
The answer is 1100.
