Computer Codes A computer is a digital system that stores and processes different types of data in the form of 0s and 1s. The different types of data handled by a computer system include numbers,alphabets and some special characters. Therefore,there is a need to change the data entered by the users into a form that the computer system can understand and process
Computer Codes ◼ A computer is a digital system that stores and processes different types of data in the form of 0s and 1s. ◼ The different types of data handled by a computer system include numbers, alphabets and some special characters. ◼ Therefore, there is a need to change the data entered by the users into a form that the computer system can understand and process
Computer Codes Different types of codes have been developed and used to represent the data entered by the users in the binary format. The binary system represents each type of data in terms of binary digits,0s and 1s. Since these codes convert the data into the binary form,the computer codes are also referred as binary codes

Computer Codes Computer professionals use different number systems according to their requirements to communicate with the computer system. All the number systems used by computer professionals to interact with computer systems come under the category of positional number system. The positional number system is a number system in which numbers are represented using some symbols called digits and the values of these numbers can be determined by taking the position of digits into consideration

Computer Codes The different positional number systems are: 。Decimal system ·Binary system 。Hexadecimal system 。Octal system
Computer Codes The different positional number systems are: ⚫ Decimal system ⚫ Binary system ⚫ Hexadecimal system ⚫ Octal system
Decimal System The decimal system is the most common number system used by human beings. ■ It is a positional number system that uses 10 as a base to represent different values.Therefore,this number system is also known as base 10 number system. In this system,10 symbols are available for representing the values.These symbols include the digits from 0 to 9.The common operations performed in the decimal system are addition (+) subtraction (-)multiplication (x),and division (/
