Data Representation

1. Detects and responds to some type of analogue/continuous input from the physical environment.
2. A collection of 8 bits. Used to store letters and numbers.
5. A whole number, positive or negative
7. Used to represent majority of keys on a standard English keyboard
9. Computer component that acts as a switch, controlling the flow of current within a circuit.
11. Error that results when the number of bits is not enough to represent the number.
12. The key component of a computer system, which contains the circuitry necessary to interpret and execute program instructions. Often known as the brain of the computer.

1. A method in computing of being able to convert numbers (both positive and negative) as a string of binary digits. The 1st bit represents the sign (0 means positive, 1 means negative).
2. A number composed of just 0s and 1s, also known as a base-2 number.
3. An international encoding standard for use with different languages and scripts, by which each letter, digit, or symbol is assigned a unique numeric value that applies across different platforms and programs.
4. A base-16 system that computers may use, consisting of the symbols 0 through 9, and the letters A through F.
6. A base-10 system that we use every day, consisting of the symbols 0 through 9.
7. Data from our environment, also said to be continuous.
8. Digital data stored in binary form.
10. The observation that computing power roughly doubles every two years.
