Number Systems - Essay ExampleThe use of antithetic tokens by different bases means that a no(prenominal)e system uses 10 different symbols and from the 11th no. the cycle of symbol repeats. The concept bases perk up long existed. Earlier for each of the counted nos. a different symbol was used. However the line of work with this system was as the list of the no. counted increased so did the no. of symbols that were used. In fact in that respect would be infinite no. of symbols if this system was followed. This problem was recognized early on by the tender civilization and the concept of bases was introduced. Egyptians used a base of 2, Babylonians base of 60, for Mayans the base was 18 and 20. Currently besides the number system that is mostly used is the denary no. system with base 10. The different no. systems that are generally used by computers areDecimal- This is the no. system which has a base of 10. The lists of symbols of decimal no. system are 0,1,2,3,4,5,6,7,8, 9 and after 9 the counting again starts from 1. The symbols in a decimal system range from 0 to 9. So after 9 are reached the system should start from 1. barely if the system starts from 1 then it will be difficult to understand. So an empty placeholder should be placed in the ones place. A symbol which is part of the list of symbols, doesnt have a value in itself but signifies great value when places along with another no. This personal line of credit is done by the symbol 0. Hence after reaching 9 the system starts from 10.Binary- The binary no. system is the no. system that is most commonly used and understood by the computers. Binary no. system has only 2 symbols 0 and 1 (Merlot, 2002). 0 and 1 are the two states that are represented by on and off. On state represents 1 and off state represents 0. For writing a no. in the binary no. system the way is to write the no. in the deviation and then attach a base 2 as subscript after closing deflexion is written. For example to wri te (25)10 in binary no. system, it is written as (11001)2.Octal- The octal no.
