Lab 1.1 Review 1. 127= 0111 1111 2^7= 128. 127 is less than 128 so it will be 0. 2^6= 64. 127 is greater than 64. 127-64=63. Place 1 bit. 2^5= 32. 63 is greater than 32. 63-32=31. Place 1 bit. 2^4= 16. 31 is greater than 16. 31-16=15. Place 1 bit. 2^3= 8. 15 is greater than 8. 15-8=7. Place 1 bit. 2^2= 4. 7 is greater than 4. 7-4=3. Place 1 bit. 2^1= 2. 3 is greater than 2. 3-2=1. Place 1 bit. 2^0= 1. 1 is equal to 1. 1-1=0. Place 1 bit. 2. 10 and 0010 are the same because all binary values are grouped in four or eight digits. 10 is a short version of 0010. 3. The available digit values in a base 5 numbering system are 1s and 0s. But we only use 5 bits of the 8 bits on the binary system. For example, you are using 16 8 4 2 1 instead of 128 64 32 16 8 4 2 1.
