What would the binary number 10000000 be in denary?
What is binary number and give two example?
A binary number is a number that consists of only 0 and 1. We use decimal numbers, which consist of numbers made up from 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. The decimal system is also known as the denary system. Binary is critical to how computers operate, but that would take time to explain in detail. For your examples that you asked for, the following is how binary and decimal represent numbers from decimal 0 to decimal 10. 0 = 0 1 = 1 10 = 2 11 = 3 100 = 4 101 = 5 110 = 6 111 = 7 1000 = 8 1001 = 9 1010 = 10
What is -67 binary?
-67 binary is -1000011 because to change denary (numbers) to binary you need to: 67divide2 = 33 remainder 1 33divide2 = 16 remainder 1 16divide2 = 8 remainder 0 8divide2 =4 remainder 0 4divide2 =2 remainder 0 2divide2 =1 remiander 0 so now count from the last bold number to the first. answer: 1000011

Why 1 GB equal 1024 mega bytes?
The key to understanding this principle is that computers use the binary number system (0's and 1's). Therefore, any time you want to get 1,000 of a certain number (1,000 being a base 10 number), you must get 2^10 (2 to the tenth power) which is 1,024. Technically, 1 GB is slightly larger than 1,024 MB at 1,073,741,824 bytes which is 2^30; but, for sake of simplicity, people normally round the number. Some people use the denary system which uses base ten and makes life more simple for us humans. In denary, 1 GB = 1,000 MB.

Why is the denary number system rejected by the computer for data representation and the binary number system accepted?
Binary is used for representing numbers in computer systems because it is the only numeric system that can be represented with on/off switches. Each of those states, on and off, can be used to represent a digit, one and zero respectively. If we used decimal storage, then it could only be represented in ways that are less efficient, or not technically feasible. For example, if we had a high-speed microswitch (equivalent to a transistor) that had ten different states, then we could use that, but there is no such thing. Alternatively, we could represent decimal using nine on/off switches per digit, each representing a value from one to nine, ensuring that no two of them would be simultaneously on. This though, is a waste of resources. Doing it that way, having eighteen on/off switches would represent a number from zero to 99. Using binary, the same number of on/off switches can represent a number from zero to 262143.

What is a bit in a computer code?
A bit is a single digit in binary - the system that a computer uses to count. As humans we use a number system called Denary or Decimal. This means that each column of numbers represents a power of 10, moving from right to left. For example: When we write a number, (512 for example) what we are really saying is: 5 1 2 (5 multiplied by 100) + (1 multiplied by 10) + 2 = 512 It's commonly believed that we use 10 as the base for our number system because we learned to count on our fingers (+ thumbs). Most of the time we have 10 digits on both hands to count on. Computers of course, don't have hands so they have to count a different way - using electrical switches that are either on or off (just like your finger might be up or down if you were counting on them). So computers count using a number system that's based on the number 2 - because a simple switch can only have two states - on or off. A bit is one of those simple switches. It can have one of only two possible values - 1 or 0.

What comes after Primary Secondary and Tertiary?
well i was interested in the same question and finally found the answer!! It's Primary,Secondary,Tertiary,and!! "quaternary" Oh and your welcome;-) ...and then I found: The sequence continues with quaternary, quinary, senary, septenary, octonary, nonary, denary. Words also exist for `twelfth order' (duodenary) and `twentieth order' (vigenary).
What is after tertiary?
Primary, secondary, and tertiary are probably the most used of the order sequences, but it does continue with quaternary (4th Order), quinary (5th Order), senary (6th Order), septenary (7th Order), octonary (8th Order), nonary (9th Order), denary (10th Order). There is also duodenary (12th Order) and vigenary (20th Order). - Peter McGriff
