Question

What is the hexadecimal equivalant of the binary number 01001011 (do it without using calculator, i.e. know you steps)?

Answer

4B

^^ trick is to split the binary into groups of 4 digits (i.e. 0100 = 4, 1011=B)

ented by a single octal digit. Hence, a binary number can be represented with hex or octal digits without much calculation, as shown in Table 2.1. A binary number 01001011 can be represented in <span>hex as 4B and in octal as 113 by simply separating the binary digits into groups of four or three, respectively. In UNIX administration, and also in many programming languages, there is often the
