OS File Operations

Q.1: What is the difference between unlink() and remove() in Linux when it comes to deleting files?

Answer:

Both the functions have the same functionality which is to delete a file from the directory but only difference is the naming convention.

Q.2: What’s the difference between file compression and file encryption?

Answer:

File compression is to reduce the size of the file by using applying certain compression algorithms, these are on the based of format and data the file has. Whereas the file encryption algorithm is used to protect the file in order to avoid disclosure of information when a file transferred. The file encryption is carried out by use of encryption-decryption algorithms.

Q.3: Can I perform file compression and encryption simultaneously on a file in Linux and Windows?

Answer:

Yes, one can perform both operations simultaneously. Firstly compress the file using “gzip” or “zip” command and then move for the encryption for which a tool can be used for the Linux like “openssl” or “gpg”. These same steps with different commands can be performed in Windows in order to perform simultaneous execution of compression and encryption.

Q.4: Can file operations be performed remotely in Linux and Windows?

Answer:

Yes both the OS supports file operations remotely. For Linux is can be done by using SSH (Secure Shell) which is the best way for secure remote file management. On Windows this can be done by using the tools like Windows Remote Desktop, FTP or network sharing to access and manipulate the files.

File operations within an operating system (OS) encompass a set of essential tasks and actions directed at files and directories residing within a computer’s file system. These operations are fundamental for the effective management and manipulation of data stored on various storage devices. In this article, we will learn different file operations and what are the system calls and APIs used to perform them in a Linux / Windows-based OS.
