The SCP Client is a software tool used for secure file transfer between computers over a network. It utilizes the SCP (Secure Copy Protocol) to ensure that files are transferred securely, protecting them from unauthorized access. This protocol is commonly used in environments where data security is a priority, such as in server management and cloud computing. Typically, the SCP Client operates through a command-line interface, allowing users to execute commands to upload or download files. It is often integrated with other tools and systems, such as SSH (Secure Shell), to provide a secure connection. Users can easily transfer files between local and remote systems with minimal setup.
