问题 单项选择题

关于计算机语言,下面叙述不正确的是

A.高级语言是独立于具体的机器系统的

B.汇编语言对于不同类型的计算机,基本上不具备通用性和可移植性

C.高级语言是先于低级语言诞生的

D.一般来讲,与高级语言相比,机器语言程序执行的速度较快

答案

参考答案:C

解析:解析:程序设计语言根据其面向对象(机器、过程)的不同分为低级语言、高级语言两种。面向机器的计算机语言称为低级语言,面向过程的计算机语言称为高级语言。机器语言是以二进制代码表示的指令集合,是计算机能直接识别和执行的语言。机器语言的优点是占用内存少、执行速度快,缺点是面向机器的语言,随机而异,通用性差,而且指令代码是二进制形式,不易阅读和记忆,编程工作量大,难以维护。汇编语言是符号化的机器语言,与机器语言相比,汇编语言容易写、容易懂,也容易记。缺点与机器语言相同,即通用性差,随机而异。高级语言是一种与具体计算机硬件无关,表达方式接近于人类自然语言的程序设计语言。高级语言的优点是通用性强,可以在不同的机器上运行,程序可读性强,便于维护,极大地提高了程序设计的效率和可靠性。
