To address this problem, a universal encoding named Unicode was ﬁrst deﬁned in 1991 and can handle over 1 million different characters. One implementation of Unicode is UTF-8, which is popular because it is backward compatible to the ASCII encoding that dominated the ﬁrst 30 years of computing. Currently over half the pages on the World Wide Web use UTF-8. It is the default character representation for Python 3. For those reasons this text will use UTF-8. 3 has part of the UTF-8 encoding showing some English characters, some symbols, and some control characters.
Assume that num1 and num2 represent numbers that are stored on the disk and that the result theSum will also be stored on the disk. Assume that the instruction itself, theSum = num1 + num2, also resides on the disk. Here is how it works: 1 Fetch Instruction: When the processor is ready to process an instruction, it fetches the instruction from memory. If the instruction is not in memory but on the disk, the memory must ﬁrst fetch it from the disk. In this way, the instruction theSum = num1 + num2 will move from the disk through memory to the processor.
