4.3 4.3 Conversion Between Number Bases 169 Conversion Between Number Bases Although the numeration systems discussed in the opening section were all base ten‚ other bases have occurred historically. For example‚ the ancient Babylonians used 60 as their base. The Mayan Indians of Central America and Mexico used 20. In this section we consider bases other than ten‚ but we use the familiar HinduArabic symbols. We will consistently indicate bases other than ten with a spelled-out subscript

studied two speculative fiction short stories. Speculative fiction is a story genre that puts ordinary people in extraordinary situations‚ asking the question “what if?” It also opens up disturbing questions about humanity and society. “Visiting the Millionaire” by George Anthony and “All Summer in a Day” by Ray Bradbury are both examples of spec-fiction because they both raise questions about humanity and society and the way that we treat other people. Another reason is that both these stories make predictions

you have a proper understanding of Text file and Binary File. If any of both seems strange to you we give short information about these files:- Text file. The text file stores the data in ASCII character. Each line of text is terminated with a special character known as EOL (End of Line) character or delimiter character in text files. When this EOL character is read or written‚ certain internal translations take place. Binary file. The Binary File stores the data in the same format as it is held

designed to do what we tell it to do. We give it commands that are mathematically calculated in a code called binary code. A Binary code is a way of representing text or computer processor instructions by the use of the binary number system’s two-binary digits 0 and 1. This is accomplished by assigning a bit string to each particular symbol or instruction. For example‚ abinary string of eight binary digits (bits) can represent any of 255 possible values and can
