Who will run programs in Computer?
- We use electronic machines with Operating Systems.
- We need to install OS on every computer.
- Every other software application such as VLC, MS-office, Clang, Java, and Python are dependent to Operating System.
- Every other application in computer run by Operating System only.
How to request?
- Every OS is available in 2 modes CUI and GUI.
- GUI – Graphical user interface – where we just click on software to run
- CUI – Command user interface – where we need to provide command to run the program.
Launch CUI mode:
- Open run prompt (windows + r)
- Type cmd
- Click on OK
- Once we open OS in CUI mode, we can specify the command to open the software.
- OS search for the specified software from the machine and opens as a separate process.
- It gives the error message in case the specified command is invalid.
- Remember, every programmer should have some command knowledge to work with CUI mode of OS.
