A worksheet activity adding binary numbers and conversions to denary. Starts with 4 bits (nibble) and moves on to 8 bits (byte) additions. There is also an accompanying answer sheet. The activity also ...

We worked our way up to logic gate implementations for half adders and full adders, as illustrated below. In closing, I asked you to start thinking about how we could use these functions to add two ...

In the computer, all data are represented as binary digits (bits), and eight binary digits make up one byte. For example, the upper case letter A is 0101001. Numbers however can take several forms.

Decimal notation describes numbers using the digits 1 through 10. Binary notation describes them using just two digits, 1 and 0, where each bit in a string represents a power of 2. The right-most bit ...

Before we plunge headfirst into the fray with gusto and abandon, let’s briefly remind ourselves how we got here. In Part 1, we introduced the concepts of integers, signed integers, and unsigned ...
