Hey guys, what’s up? Today this blog will discuss the Commands of the Computer system. I hope you are alright everywhere. Welcome to my site Engineering Technology. Today in this article I will discuss the Most Important Top 20 Commands of the Computer System.
The command is an important part of a computer system. So this is an important article for you. Please visit from start to end. Then you can find out the exact important knowledge of the command of the computer system.
So friends what is the command needed for the computer system? Power is a usable and essential part of the computer system. In this article, you can get the Top 20 most essential Commands of Computer systems. What is today’s topic? Those are listed below:
- Commands of the Computer system?
- Internal Commands of the Computer System?
- External Commands of the Computer System?
This is the main point that will be discussed in this article. And also pointed out different types of commands, Syntax, and Their Functions. Let’s begin 》》》》》
What is the command of the computer system?
A command is an order or instruction given to the computer to perform a specific task and get accurate output. The command is mainly of two types. Which are internal command and external command.
The internal and external commands are classified into different functions. So friends you should read clearly about the internal and external commands with different categories.
What is the internal command of the computer system?
First of all, I can explain of internal command of the computer system.
The commands which are recognized by the Command.com file of MS-DOS are called internal commands. When a computer is started, such types of commands are automatically loaded into the computer’s memory because they are the internal parts of the command.com file. Examples of internal commands are CLS, DIR, COPY, DEL, REN, MD, CD, DATE, TIME, PROMPT, etc.

So friends this is the most important Commands of Computer systems. These are not understood without practical in the computer. So To practice on the computer all of the above commands of the computer and show the results.
For the practice of commands of the computer. Open the Command Prompt [By pressing CMD] in the search box on the computer. Then you can easily apply all the above commands in the CMD panel.
The most important top 20 Commands of the Computer are for that person who can easily use CMD on the computer. Who should be charging, viewing, and setting indirectly? All the operating system is controlled by this above command. Making easily directory files on the computer settings on the computer than using this command.
So friends how was this article? I hope this article is helpful for you. You got all of the knowledge about the command. Thanks, friends to visit my site. Keep supporting and keep joining us on Instagram. Thank you.
