Router(config)#Copy running-config startup-config
This is an incomplete command. However, this indicates that the running configuration will be saved on the device to a different location.
The IOS command to copy the running configuration to NVRAM is copy running-config startup-config. This command saves the current configuration in RAM (running config) to the non-volatile memory (NVRAM), ensuring that the configuration is preserved after a reboot. You can also use the shorthand version, wr or write memory, to achieve the same result.

The router command used to copy the running configuration to NVRAM is copy running-config startup-config. This command saves the current active configuration so that it will be retained after a reboot. You can also use the shorthand version wr (short for "write memory") to achieve the same result.
To save the running configuration on a router, you typically use the command copy running-config startup-config in the privileged EXEC mode. This command copies the current configuration stored in RAM (running-config) to NVRAM (startup-config), ensuring that the configuration is retained after a reboot. Alternatively, you can use the shorthand command write memory. Always confirm the save by checking the startup configuration with the show startup-config command.
RouterC#copy running-config tftp [copy run tftp]
A technician would enter the command copy startup-config running-config to copy the configuration stored in the startup configuration file (which is saved in NVRAM) to the running configuration (stored in RAM). This action allows the device to apply previously saved settings without needing to re-enter them manually. It is often used after making changes to ensure that the system is configured as intended. Additionally, it can help restore configurations after a reboot or power cycle.
It is short for copy running-config starting-config. Running-config is the configuration of the router as you have modified it and which is currently operating, held in RAM (gone after a reboot), and you copy it to the starting-config which is in NVRAM and gets loaded by the router when it boots/ So essentially you're saving what you have now to the persistent storage so your router will still work after a reboot.
