II．Translate the following terms or phrases from English into Chinese and vice versa:
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.
