### 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

###### Asked in Computer Terminology

### 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
