摘要:
A method and apparatus for providing software by function units are provided. In the method, at the streaming client, a functional unit identification is created for identifying a function requested from a user by intercepting a request of a predetermined function in application software from a user. Then, it determines whether a functional unit corresponding to the created functional unit identification is streamed or not, and determines whether each of execution pages of the functional unit is streamed or not when the functional unit is not streamed. After determining, a streaming list is composed with execution pages that are not streamed based on the determination result. Then, a streaming service is requested by transmitting the composed streaming list to the streaming server, and execution pages transmitted from the streaming server are received and stored.
