You are given the following piece of code: try { var response = await client.GetAsync( "https://venus.sod.asu.edu/WSRepository/Services/EncryptionRest/Service.svc/ Encrypt?text=" + EncryptEntry.Text); response.EnsureSuccessStatusCode(); result = (await response.Content.ReadAsStringAsync()).Replace(@"""", ""); } (1) What type of service does the code call? RESTful service (2) How does the code save CPU time? It uses two threads. The first thread terminates after calling the service, and the second thread can go to "wait" state while waiting for the result.
