Binary Code

Map the two states of visual or physical examples, such as switches, to 0 and 1 and write the resulting bit patterns.

Determine the positional value of each bit in a binary number using a visual powers-of-two place-value diagram.

Convert an unsigned binary number of up to eight bits to decimal using a place-value chart.

Convert a decimal whole number from 0 to 255 to an eight-bit binary pattern, including leading zeros, using a place-value chart.

Partition bit strings into four-bit nibbles and eight-bit bytes and determine their sizes in bits.

Add two unsigned binary numbers of up to four bits using visual sum-and-carry rules, including results that require a fifth bit.

Encode and decode uppercase English letters and decimal digits as eight-bit byte patterns using a standard ASCII table.
