Reading comprehension.(阅读理解) We know a computer is a machine that processes data(stored in main memory )into information, under control of a stored program. We also know that, internally, a computer is a binary machine; thus the data and the program instructions must be stored in binary form. Characters are represented in a binary code. Numbers are stored as binary numbers, with each bits positional value significant. A computer's main memory is divided into bytes, words or both( depending on the system), and each of these basic storage units is assigned an address. Using this address, the processor can read or writeUnit 4 The Fundamentals of Computer Hardware Text 1 Organization of Computer System Components Exercises 1.
