NUMBER SYSTEM (or system of numeration) is a writing system for expressing numbers‚ that is a mathematical notation for representing numbers of a given set‚ using graphemes or symbols in a consistent manner. It can be seen as the context that allows the symbols "11" to be interpreted as the binary symbol for three‚ the decimal symbol for eleven‚ or a symbol for other numbers in different bases. BINARY TO HEXADECIMAL Example 1. Consider Binary: 1000100100110111 (a 16-bit Byte) STEP 1 Break

physical systems are represented by the voltages 5V and 0V‚ or something close to that. While the restriction to two states seems limiting it makes many things easier because problems due to noise are minimized. It is generally very easy to reliably distinguish between logic 1 or logic 0. Since many quantities cannot be represented by two states‚ more than one binary digit can be used to represent a number. For example the number 2510 (twenty five base 10) can be represented by the binary number 110012

can be a mental stimulus‚ perception‚ representation‚ knowledge‚ or even an instruction. The examples of data can be facts‚ analysis‚ or statistics. In computer terms‚ symbols‚ characters‚ images‚ or numbers are data. These are the inputs for the system to give a meaningful interpretation. In order‚ data in a meaningful form is information. In a computer‚ however‚ all data is represented by the state of the computer’s electronic switches. A switch has only two possible states- on and off –so it

Answer 3. What would you call a device that works with binary data? Any device that works with binary data is called a digital device. 5. What are the short words that are used in assembly language called? Assembly language uses short words known as mnemonics for instructions in a program. Exercises 1.
