Our number system, the decimal system, uses ten symbols. Therefore, decimal is said to be Base Ten. By describing systems with bases, we can gain an understanding of how that particular system works.
Once we reach the last symbol, we create a new placement in front of the first and count that up. The placement of a symbol indicates how much it is worth. Each additional placement is an additional power of Consider the number of We know this number is quite large, for example, if it pertains to the number of apples in a basket. That's a lot of apples. How do we know it is large? We look at the number of digits. Each additional digit represents a higher and higher quantity. This is applicable for Base 10 as well as to other bases.
Knowing this will help you understand the other bases better. Binary is another way of saying Base Two. So, in a binary number system, there are only two symbols used to represent numbers: 0 and 1. When we count up from zero in binary, we run out of symbols much more frequently. From here, there are no more symbols. We do not go to 2 because in binary, a 2 doesn't exist. Instead, we use In a binary system, 10 is equal to 2 in decimal.
Since this is base two, however, the numbers don't get quite as large as it does in decimal. Even still, a binary number with 10 digits would be larger than in decimal. The binary system is useful in computer science and electrical engineering.
Transistors operate from the binary system, and transistors are found in practically all electronic devices. A 0 means no current, and a 1 means to allow current. With various transistors turning on and off, signals and electricity is sent to do various things such as making a call or putting these letters on the screen.
Computers and electronics work with bytes or eight digit binary numbers. Each byte has encoded information that a computer is able to understand. Many bytes are stringed together to form digital data that can be stored for use later. Octal is another number system with less symbols to use than our conventional number system.
Octal is fancy for Base Eight meaning eight symbols are used to represent all the quantities. They are 0, 1, 2, 3, 4, 5, 6, and 7. When we count up one from the 7, we need a new placement to represent what we call 8 since an 8 doesn't exist in Octal. So, after 7 is Just like how we used powers of ten in decimal and powers of two in binary, to determine the value of a number we will use powers of 8 since this is Base Eight. Consider the number in base eight. Each additional placement to the left has more value than it did in binary.
The third digit from the right in binary only represented 2 , which is 4. In octal, that is 8 which is The hexadecimal system is Base Sixteen. The octal number system uses digits from 0 to 7 which can be made from binary numbers by grouping binary digits in its 3-bit representation. Octal numbers use a lesser number of digits as compared to decimal and hexadecimal which makes it easy to compute in fewer steps.
The octal number system is a number system of base 8 which means that 8 different symbols are needed to represent any number in the octal system. The symbols are 0, 1, 2, 3, 4, 5, 6, and 7. The advantages of the octal number system are that it is one-third of the binary number system, the conversion process of octal to binary and vice versa is very simple, and in the octal form, it is simple to handle input and output. The disadvantages of the octal number system are that there is an additional requirement of a system within the computer that provides easier conversion of octal numbers to binary numbers before it is actually applied to a digital platform.
To convert octal to decimal , we need to expand the number with the base of eight where each number is multiplied with the reducing power of 8. Once the product is obtained, we add the numbers to arrive at the decimal number. To convert decimal to octal , the decimal number is divided by 8 each time a reminder is obtained from the previous digit.

Definition of Octal Number System 2. Conversion from Octal to Binary Numbers 3. Conversion from Octal to Decimal number 4. Conversion from Decimal to Octal 5. Conversion from Octal to Hexadecimal Numbers 6. Solved Examples 7. Binary system is used for representing binary quantities which can be represented by any device that has only two operating states or possible conditions. For example, a switch has only two states: open or close.
In the Binary System, there are only two symbols or possible digit values, i. Summary: For decades, scientists have known that DNA consists of four basic units — adenine, guanine, thymine and cytosine. Those four bases have been taught in science textbooks and have formed the basis of the growing knowledge regarding how genes code for life.
First Base — Kissing. Third Base — Oral Stimulation. Home Run — Penetrative Sex. Some people only consider French kissing as getting to first base. Second base is direct physical contact, usually meaning his hands to her breast. This is called base power of 8. The decimal value of any octal number can be determined using sum of product of each digit with its positional value.
The octal numbers are not as common as they used to be. However, Octal is used when the number of bits in one word is a multiple of 3. The main advantage of using Octal numbers is that it uses less digits than decimal and Hexadecimal number system. So, it has fewer computations and less computational errors.
