Q2) Describe the binary number system.
Answer: The number system that only uses two digits,0 and 1,is called the binary number system.In a computer,all counting and calculations use the binary number system.Because of the way the number system is organized,grouping is often done in groups of eight bits,each of which is called a byte.Counting in binary goes like this: 0,1,10,11,100,101,and so forth.For example,in binary code the number 25 is 0001 1001.When text is stored in a computer,every letter or other character is first converted to a code using only zeros and ones.The most common coding method for text is ASCII (American Standard Code for Information Interchange).
