Study Notes

Binary Representation

Unsigned binary representation can only represent positive binary numbers.
Signed binary representation, such as 2's complement, can represent both positive and negative numbers.

2's Complement Form

During add and subtract operations in 2's complement form, the carry generated from the most significant bit (MSB) is discarded.
The main advantage of using 2's complement signed representation is that it simplifies the handling of positive and negative numbers.

Binary Counters

A 5-digit car odometer can reach a maximum count of 99999 before rolling back to 00000.
A calculator with an 8-digit display has a limitation in handling integer numbers, as it can only display up to 8 digits.

Binary Shift Operations

The multiplication factor is determined by 2^n when there are n number of bit shifts.
Shifting a binary number left by 3 bits results in the original number multiplied by 2^3.
Shifting the binary number 11000 left by 3 bits results in 11000000.
In binary division, the division factor is determined by 2^n when there are n bit shifts.
Shifting a binary number right by 2 bits results in the original number divided by 2^2.
Shifting the binary number 01010 right by 2 bits results in 00101.

Binary Numbers and Operations

Positive and negative numbers are represented in digital systems using the binary number system, where 0 represents positive and 1 represents negative.
A right shift by a single bit signifies a division by 2.
A Borrow occurs in binary subtraction when the result of a subtraction is negative.
Binary subtraction is similar to decimal subtraction, with the exception of borrowing.
The result of multiplying 1 by 0 in binary is 0.
Binary multiplication is different from decimal multiplication in that it uses bitwise operations.
A left shift by a single bit accomplishes a multiplication by 2.
Borrowing is necessary in binary subtraction to ensure correct results when subtracting a larger number from a smaller number.
