FTA: “Based on the above picture, another important observation is that to represent the number 1078 in binary, we need at least ten memory cells (bits) for it (look at the most significant power of 2 used, which is 10)”
As the picture shows, we need 11 bits, with powers ranging from zero to ten, both included (under the implicit assumption that we want to represent all integers between 0 and 1078. If all we want to represent is 1078, we can do with one or, pedantically, zero bits)
