Question

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

Answer

113

^^

trick is to split the binary into groups of 3 digits (i.e. 01 = 1, 001 = 1, 011 = 3)

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 hex as 4B and in <span>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 ambiguity of whethe
