Now you already know the most important thing about 203 in binary form. 11001011 is binary 203. That is if the binary in unsigned.

If 203 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 00011001011 in which the leftmost bit is the sign bit, followed perhaps by more trailing 0’s, and then by magnitude bits.

The reason to have the binary 203 signed is to accommodate for negative numbers, in which case the sign bit is 1 in our example.

Therefore, minus 203 signed using two’s complement, will start with one or more 1’s, but the exact code for -203 decimal to binary depends on the signed number representation system and number of bits available.
