CCNA 二进制子网掩码－子网掩码只能有这9个数字 * Purpose: This figure explains how subnet masks are converted to decimal addresses. Emphasize: Review binary-to-decimal conversion, bit weighting, and conversion. Explain the logical AND. One possible explanation of the logical AND follows. We will need to be able to perform a logical AND on the binary numbers. Just take two binary numbers and place one above the other. The ones in the bottom are like a pipe—the number above it just drops through. The zeros are like a clogged pipe, so nothing comes out in the answer. Presenting a truth table will help some students understand. You might need to give more than one explanation. Note: You might want to hand out a binary-to-decimal conversion sheet if you have not already done so. We have not included one in the lab section. It is more useful to have one that is on a separate page from the labs.
