如果你对编程感兴趣,那么请注意,编程语言(programming languages)通常分为两类:高级(High-Level)和低级(Low-Level),每一类都有自己的用途。知道哪一个最适合您,很大程度上取决于您的知识,这就是我们决定解释两者之间差异的原因。
低级和高级编程(Programming)语言
今天,我们将解释高级和低级编程的定义,以及不同的类型。当您完成阅读本文后,预计您将对未来重点关注哪种语言有所了解。
请记住(Bear),编程并不容易,即使对于专业人士来说也不容易,因为事情随时可能出错。如果你不是为解决复杂问题而生的,那么学习编码可能不是你的事。
1]什么是高级编程
现在,根据我们多年来所了解的情况,有一些定义高级编程的特征,我们将研究其中的一些。
好的,所以高级编程更类似于人类语言,因为它是可读的,或者更多。此外,这些语言不参与内存管理和特征抽象。
高级编程语言的主要示例是 C#、Python、Java、Ruby等。

2]什么是低级编程
您会注意到的第一件事是与High-level(High-level)相比,相反的低级语言有多少。你看,它们没有抽象特征,但是当涉及到内存管理和计算机读取的能力时,它们就领先了。
此外,这些语言根本不接近人类语言,因此阅读它们并不容易。
至于示例,请查看机器代码和汇编语言以了解我们在说什么。

3]对高级编程语言的更深入解读(Deeper)
好的,事情就是这样。高级语言都具有如上所述的抽象,这很好,因为它使它们更易于使用和理解。如果我们查看下面的代码行,我们可以看到它是如何可读且更像人类的:
# Create the data for the graph.
v <- c(9,13,21,8,36,22,12,41,31,33,19)
# Give the chart file a unique name.
png(file = "histogram.png")
# Create the required histogram.
hist(v,xlab = "Weight",col = "yellow",border = "blue")
# Save the file.
dev.off()
正如你所看到的,它只是简单的几行代码,如果你阅读得当,你就会明白你得到了什么。此外,无需使用高级语言来管理内存。
就高级编码中一些最重要的部分而言,它们是变量、对象、例程和循环。你看,这些抽象使得高级语言比低级语言更容易使用。
此外,高级编码允许用户仅用一行代码发送数十条命令。此外,应该注意每种高级编程语言都有自己的语法编写方式,因此,有些会比其他的更容易。

4]对低级编程语言的深入解读(Deeper)
正如我们上面所说,低级编程语言更符合计算机系统而不是人类语言,因此,以正常方式阅读它是不可能的。最知名的低级编程语言之一是机器码(Machine),它都是关于随机数的。
你看,机器(Machine)代码只包含传递给计算机的个人指导方针,这意味着它缺乏抽象。
现在,我们不应该让机器(Machines)只理解字节,尽管它们主要以十进制、十六进制表示法或二进制表示。我们知道二进制文件比其他文件使用得更多。
机器码示例:
000000 00001 00010 00110 00000 100000
如您所见,不可能阅读上面的代码来了解它会做什么。另一方面,只要程序员指定明确的方向,计算机就非常有能力阅读这种语言。
5]你应该(Should)学习一种还是两种编程语言?
这是一个很难回答的问题,因为这两种语言各有利弊。你看,高级语言更容易学习和掌握。更不用说,高级语言更安全,因为它们包含某些保护措施,使程序员更难编写旨在破坏计算机的代码。
低级语言则完全相反,因此,它们不用于为 Web 或应用程序编写代码,而主要用于驱动程序软件或操作系统内核。
Difference between Low-level and High-level Programming languages
If yоu’re interested in programming, then please note that programming languages are usually separated in two classes: High-Level and Low-Level, and each has its own purpose. Knowing which one is best for you, depends a lot on your knowledge, which is why we’ve decided to explain the differences between both.
Low-level and High-level Programming languages
Today, we are going to explain the definition of high and low-level programming, and the different types. When you’ve completed reading this article, it is expected that you’ll have some idea of which language to focus on going forward.
Bear in mind that programming is not easy, not even for professionals because things can go wrong at any time. If you are not built for solving complex problems, then chances are learning to code is not your thing.
1] What is a high-level programming
Now, from what we’ve come to understand over the years, there are a few characteristics that define high-level programming and were going to look at some of them.
OK, so high-level programming is more akin to human language due to the fact it is readable, or more so. Furthermore, these languages do not take part in memory management and feature abstraction.
The main examples of high-level programming languages are C#, Python, Java, Ruby, and more.

2] What is Low-level programming
The first thing you’ll notice is how much of an opposite low-level language are when compared to High-level. You see, they do not feature abstraction, but when it comes down to memory management and the ability to be read by computers, they are ahead.
Additionally, these languages are not close to human language at all, so reading them is not easy.
As for examples, look to machine code and assembly language to get an idea of what we’re talking about.

3] Deeper interpretation of high-level programming languages
OK, so here’s the thing. High-level languages all feature abstraction as explained above, and this is good because it makes them easier to use and understand. If we look at the line of code below, we can see how it is readable and more human-like:
# Create the data for the graph.
v <- c(9,13,21,8,36,22,12,41,31,33,19)
# Give the chart file a unique name.
png(file = "histogram.png")
# Create the required histogram.
hist(v,xlab = "Weight",col = "yellow",border = "blue")
# Save the file.
dev.off()
As you can see, it’s just simple lines of code, and if you read it properly, you will understand what you’re getting what comes after. Furthermore, there is no need to manage memory with high-level language.
In terms of some of the most important parts of coding in high-level, they are variables, objects, routines, and loops. You see, these are the abstractions that make high-level languages so easy to use when compared to their lower-level counterparts.
Also, coding from the high-level allows the user to send dozens of commands with just a single line of code. Furthermore, one should note that each high-level programming language has its own way of writing syntax, therefore, some will be easier than others.

4] Deeper interpretation of low-level programming languages
As we’ve stated above, low-level programming languages are more aligned with the computer system rather than human language, therefore, reading it in a normal fashion is impossible. One of the most known low-level programming languages out there is Machine code, and it’s all about random numbers.
You see, Machine code only contains the individual guidelines passed down to the computer, which means, it lacks abstraction.
Now, we should not that Machines only understand bytes, although they are mainly represented in decimal, hexadecimal notation, or binary. We understand that binary is used more than the others.
Example of machine codes:
000000 00001 00010 00110 00000 100000
As you can see, it’s impossible to read the above code in order to get an idea of what it will do. The computer, on the other hand, is very much capable of reading this language as long as the programmer specifies clear directions.
5] Should you learn one or both types of programming languages?
That’s a difficult question to answer since both languages have benefits and cons. You see, high-level languages are easier to learn and grasp. Not to mention, high-level languages are safer because they contain certain safeguards to make it harder for programmers to write code designed to destroy a computer.
Low-level languages are the complete opposite, and as such, they are not used for writing code for the web or apps, but primarily driver software or operating system kernels.
