Question

1. A......
processes numbers in computer​

Answer 1

Answer:

In a Computer numbers are represented by binary digits 0 and 1. Computers employ binary arithmetic for performing operations on numbers. Since it gets cumbersome to display large numbers in binary form computers usually display them in hexadecimal or octal or decimal system.

Answer 2

Answer:

Computers use binary numbers. The advantage of hexadecimal (and octal for that matter) codes is that it is easily convertible to binary character by character (unlike decimal code). In the case of hexadecimal one hexadecimal character corresponds to four bits. Using binary code directly by a human is very inconvenient (too many 0s and 1s), so hexadecimal code is kind of a compromise.

Explanation:

• Computers use the binary number system to store data and perform calculations.
• In mathematics and digital electronics, a binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically 0 (zero) and 1 (one). The base-2 numeral system is a positional notation with a radix of 2. Each digit is referred to as a bit.
• An easy method of converting decimal to binary number equivalents is to write down the decimal number and continually divide by 2 (two) to give a result and a remainder of either a “1” or a “0” until the final result equals zero. So for example. Convert the decimal number 29410 into its binary number equivalent.
• Binary numbers use the same rules as decimals - the value of any digit always depends on its position in the whole number. It all gets down to bases. Decimal uses base ten so that every time a number moves one position to the left in a figure, it increases by a power of ten (eg. 1, 10, 100, etc).
• Binary is a base 2 number system invented by Gottfried Leibniz that is made up of only two numbers: 0 and 1. This number system is the basis for all binary code, which is used to write data such as the instructions that computer processors use, or the digital text you read every day.
