Learning DOS (disk operating system) is the first step to learning to use and operate microcomputers, but many beginners have never been exposed to computers, which has affected their further learning. Based on years of teaching experience, I believe that combining some computer knowledge with some concepts in our daily life can have good results.
1. About the format of DOS commands
Computers are designed and manufactured by humans, so to allow the computer to complete a specific operation, corresponding commands must be issued to the computer. This is like a leader sending instructions to subordinates. For ease of operation, people have specially formulated a unified command syntax format for DOS:
[d:][path\]Command word[parameter][switch character/]
Where: [d:] is a drive letter, which can be A, B, C, and D;
[path\] is a path, which can be a root directory or a subdirectory;
[Parameter] is used to indicate the object and target of the command operation, including the three parts [d:][path\]<file name>;
[Switch character/] Add an English letter or number from "/" to the command is an additional function.
This grammatical format is the same as our Chinese grammar. At that time, you can only write articles according to this grammar, otherwise there will be problems and grammatical errors. For example: subject-predicate object is the most typical Chinese grammar. "We learn computers" meets this grammatical provision, but if written as "Learn from our computers" or "Learn from our computers", it will make people unable to understand and accept. Therefore, when operating DOS commands, we must strictly follow the DOS command syntax and do not make any mistakes. The above DOS command syntax format applies to both external commands of DOS and internal commands of DOS.
2. About some keywords in DOS
It is actually not difficult to learn DOS. If an error occurs during operation, the computer will display the corresponding error message or prompt message. The reason why it is difficult for beginners to master is that most of them do not know English words or do not understand computer-specific terms. However, when using a computer, if you can grasp some keywords, you can roughly understand the content of the error information or prompt information, and make judgments and processing based on this information. For example: If the file cannot be found, the computer will prompt: File not Found; if there is a problem with the command typed, the computer will prompt: Bad COMMAND (wrong command). If the path is wrong, the computer will prompt: Invalid path. The following DOS keywords will help beginners understand and master DOS prompt information in a short time.
Noun: File (file) Directory (directory) path (path) Command (command) Disk (disk) System (system) Drive (device) Name (name) Data (data) Date (date) Time (time)
Adjective: Bad (bad) invalid (invalid) error (error)
Verb: Found or Find Boot
Others: not or non(no) and(and) or(or) Cannot(cannot)
