Binary
Akopọ
A computer's processor only ever switches between two electrical states, and everything it stores or calculates has to be built out of those two states. Numbers, letters, photographs and even the instructions of the program itself are all, deep down, patterns of binary digits.
In this lesson you will learn to convert confidently between binary, denary and hexadecimal, add two binary numbers and recognise when the result overflows an 8-bit register, shift a binary pattern left and right, and represent both positive and negative whole numbers using sign-and-magnitude and two's complement.
Awọn Afojusun
- Understand that computers use binary to represent data (numbers, text, sound, graphics) and program instructions
- Understand how computers represent and manipulate numbers (unsigned integers, signed integers (sign and magnitude, two's complement))
- Be able to convert between binary and denary whole numbers (0-255)
- Understand how to perform binary arithmetic (add, shifts (logical and arithmetic)) and understand the concept of overflow
- Understand why hexadecimal notation is used and be able to convert between hexadecimal and binary
