1. A communication system comprising:
a vehicle including a control device configured to store a control program;
a terminal configured to give a notification of predetermined information; and
a server configured to:
determine whether update data for the control program is transmitted to the vehicle via the terminal or the update data is transmitted to the vehicle without intermediation of the terminal,
(i) in response to determining that the update data is transmitted to the vehicle via the terminal,
transmit the update data to the terminal, and
transmit, to the terminal, first information about a transmission status of the update data transmitted from the server to the vehicle via the terminal with a first data amount, and
(ii) in response to determining that the update data is transmitted to the vehicle without intermediation of the terminal,
transmit the update data to the vehicle without intermediation of the terminal, and
transmit, to the terminal, second information about the transmission status of the update data transmitted from the server to the vehicle without intermediation of the terminal with a second data amount,
wherein the first data amount with which the first information is transmitted from the server to the terminal in a case that the server transmits the update data to the vehicle via the terminal is smaller than the second data amount with which the second information is transmitted from the server to the terminal in a case that the server transmits the update data to the vehicle without intermediation of the terminal.
