Zhang Ning: Well, there might many causes for system crash. One of them is software. The simplest operation like installing and uninstalling might cause a crash in system. Problems within the system may also do that, so you have to be very careful when deleting DLL files, modifying Windows registry, or upgrading the operating system. Another cause is the hardware problem. Have you tried backing up the files? It would be a great help in system restoration when the problem doesn’t lie in the hardware. Cheng Hong: The service personnel installed a ghost program for me when I bought the computer. Will I lose the data in my hard disk if it is restored? Qian Liang: Not except the data on C: drive, where files on your desktop or in My Documents are stored. You may move them into other locations with a bootable disk or under DOS if there are any. Cheng Hong: There are a lot of learning materials in My Documents and on the desktop. Would you please help me transfer them? It might save me the trouble of calling for customer services, and what’s more important, I’d learn a lot from you. Qian Liang: No problem.

Thedifficulty of writing programs in themachinelanguage of 0s and 1s led first to the development of assembly language, which allowsprogrammersto use mnemonics for instructions and symbols for variables. Such programs are thentranslatedby a program known as an assembler into the binary encoding used by thecomputer. Other pieces of system software known as linking loaderscombinepieces of assembled code and load them into the machine’s mainmemoryunit, where they are then ready for execution. The concept of linkingseparatepieces of code was important, since it allowed “libraries” ofprogramsto be built up to carry out common tasks—a firststeptoward the increasingly emphasized notion of softwarereuse. Assembly language was found to be sufficientlyinconvenientthat higher-level languages (closer to natural languages) were invented in the 1950s for easier, fasterprogramming; along with them came the need for compilers, programs that translatehigh-levellanguage programs into machine code. As programming languages became morepowerfuland abstract, building efficient compilers that create high-quality code in terms ofexecutionspeed and storage consumption became an interesting computer science problem in itself.
