Programming at its “lowest level” involves communicating with specific digital hardware in “machine language,” sequences of bits (0’s and 1’s). The particular machine model will classify sequences of bits into a fixed number of “types,” say instructions, signals, addresses, and data;...
Thisabstraction layermeans that with high-level languages, you’re not concerned with the nitty-gritty details of what’s happening inside the machine, such asmemory managementor the specific instructions to the CPU. Instead, you can focus on developing thelogic of the programand let the language...
高级语言 高级语言(High-level programming language)相对于机器语言(machine language,是一种指令集的体系。这种指令集,称机器码(machine code),是电脑的CPU可直接解读的数据)而言。是高度封装了的编程语言,与低级语言相对。它是以人类的日常语言为基础的一种编程语言,使用一般人易于接受的文字来表示(例如汉字、不规则...

A high-level programming language like PASCAL offers data types, variables, constants and operators, with which the programmer can represent the actual world as a model inside the computer. The world of numbers and text has been represented in the computer for many years by various kinds of ...
The Low-level programming languages are actually a declarations that uses a bit of abstraction to the machine code. As, the machine code is actually hidden behind the instructions the low level language are easily readable. The lowest low level language is Assembly languages that is just next...
