- Generally speaking, single bits are used only for storing Boolean values (true or false). In most programming languages, true equates to one, while false equates to zero. The smallest unit of data that can be addressed in computer memory is the byte. The definition of the byte has varied over the years but it is now generally cons…
- Integers are whole numbers. The range of values that can be stored as an integer depends on whether or not the number is signed (i.e. positive or negative), and how much memory is allocated for it in memory. Programming languages can generally represent integers that are signed or un…

https://www.binarytranslator.com/why-binary-numbers-are-used-by-computersAll the characters are stored by computers as binary data numbers. The digits: 0 and 1, are used by binary code to represent computer text or instructions and a bit string is assigned to each symbol or instruction. The assigned strings have the …

- Every computer is made up of many electronic components. That is why a basic knowledge of electronics is needed to understand how and why binary numbers are used in computers. We’ll keep it very simple. A computer is built with many connections and components, which are used to transfer and store data, as well as communicate with other components. Most of that storing…

Apr 26, 2018 · There's no difference between text data or any other types of data per se, so the computer can't distinguish between an ASCII character or a plain number in memory. However, the process acting on that data treats the different memory contents differently and comes with the "knowledge" of the type of data baked into its instruction sequence.

- No two manufactured parts are exactly alike, but small differences do not impair the usefulness of the final product. For mechanical parts, we might say that a difference of ten thousandths of an inch, plus or minus, from the nominal, or design value is good enough. Depending on the part, the amount of deviation, or tolerance, might be larger or smaller, but there is always the concept of …

Answer (1 of 18): All computer data is just numbers. Each character of text is stored as a number. When you press a key on the keyboard, the keyboard sends a number, corresponding to the key that was pressed. When text is displayed on your monitor, each …

This is something to be aware of when writing low-level software to to do computations. • The more bits we use to represent a number, the greater the precision of the representation and the more memory we consume. Also, if the natural representation of the machine does not use that number of bits and repre-

All signals inside a computer have two (and only two) different therefore binary values: 0 and 1. They can be thought of as off (0) and on (1) or false (0) and true (1). In computer terminology, one piece of information which can store either 0 or 1 is called a bit. So a bit represents values from 0 to 1 (2 values).
