IP addresses are assigned by the network administrator, or ISP. The computer does have to be configured manually to respond to that specific address.
It depends on what your computer's sharing settings are configured to.
A dynamic address, assigned by the DHCP server. Static addresses can also be assigned by the DHCP server through reservations using the unique MAC addresses to identify each machine. This ensures a machine receives the same address each time it requests an address from the server.

Nothing. That is not a valid IP address as its stands however ip addresses with the first 2 octets of 169.254.xxx.xxx means that Automatic Private IP Addressing has been enabled because no DHCP server was found and no static address has been defined.
When it is new it will initially be configured. When a new operating system is installed, it will be configured. Installing some software or changing some settings may require a little re-configuring. If you are chaning the country settings, for example. If the computer is being connected to a network it may need to be configured. If it is being upgraded it may be configured. If it is having a complete change in usage, maybe as a server instead of a client it may be configured. So there are many reasons when a computer would be configured.

It depends on what is stating invalid parameter, the system, the operating system, etc. Far more information is needed to troubleshoot.
Mostly two things. The hardware has to be compatible so it is configured to be. Software, which has to run on and be supported by the hardware. It is also configured for this purpose.
The IP address.
All computers store IP addresses. ;) <3
