Binary and Hex Flashcards

A number system using base-2, consisting of only 0s and 1s.

A number system using base-16, consisting of digits 0-9 and letters A-F.

Divide the number by 2 repeatedly, recording remainders. Read remainders from bottom to top.

Multiply each binary digit by its place value (powers of 2) and sum the results.

Divide the number by 16 repeatedly, recording remainders. Convert remainders to hexadecimal digits.

Multiply each hexadecimal digit by its place value (powers of 16) and sum the results.

Group binary digits into 4-bit chunks starting from the right, then convert each chunk to hexadecimal.

Convert each hexadecimal digit into its 4-bit binary equivalent.

Add binary digits column by column. Carry over if the sum exceeds 1.

Occurs when the result of a binary addition exceeds the number of bits available.

Shifts all bits to the left, multiplying the number by 2 for each shift.

Shifts all bits to the right, dividing the number by 2 for each shift.

Characters are represented using binary codes, such as ASCII or Unicode.

A character set using 8-bit binary codes to represent characters.

A character set that supports a wider range of characters than ASCII.

Computers use binary because they operate with two states: on (1) and off (0).

0+0=0 1+0=1 1+1=0(carry over the 1) 1+1+1 = 1
